  • Android学习笔记(九) 视图的应用布局效果

      最近少了写博客,可能最近忙吧,工作上忙,因为工作原因也忙于学习,也没记录什么了,也没有按照之前的计划去学习了。现在就记录一下最近学到的。

      要做Android应用,界面设计少不了,可惜之前一直在用WindowPhone的,对别的系统的界面风格严重不了解,稍留意了一下,发现有几种风格的,上网找了代码学习了一下,还是能做出来的

    豌豆荚的布局

      这种布局类似用Tab来布局,通过左右滑动切换不同的界面,或者点击顶部的文字来切换。不过在这里我并没有用上TabHost,对整个页面来说我把它切成了3部分:文字导航、绿色的那小条子,还有下面主要的内容

    • 最上面的文字导航我就用一个线性布局把TextView排列起来
    • 绿色的小条子也是用了一个线性布局里面放了一个ImageView,这个ImageView是需要加动画的
    • 主要内容我就用了ViewPager,这是一个好东西,滑动切换时有效果,这里是用到了碎片Fragment,虽然说是Android3.0后才加上去的东西,但是2.3的系统还是能用得上。

    然后用一个线性布局把上面这三块排列起来就行了

    下面就展示一下布局的代码

     1 <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
     2     android:layout_width="match_parent"
     3     android:layout_height="match_parent"
     4     android:orientation="vertical" >
     5     
     6     <LinearLayout
     7         android:layout_width="match_parent"
     8         android:layout_height="wrap_content"
     9         android:orientation="vertical" >
    10 
    11 
    12 
    13         <LinearLayout
    14             android:id="@+id/imf_linearLayout1"
    15             android:layout_width="fill_parent"
    16             android:layout_height="wrap_content"
    17             android:paddingBottom="5dip"
    18             android:paddingTop="10dip" >
    19 
    20             
    21 
    22             <TextView
    23                 android:id="@+id/imfLbRealTime"
    24                 android:layout_width="fill_parent"
    25                 android:layout_height="fill_parent"
    26                 android:layout_weight="1.0"
    27                 android:gravity="center"
    28                 android:text="Tab1"
    29                 android:textColor="@color/select"/>
    30 
    31             <TextView
    32                 android:id="@+id/imfLbOnLine"
    33                 android:layout_width="fill_parent"
    34                 android:layout_height="fill_parent"
    35                 android:layout_weight="1.0"
    36                 android:gravity="center"
    37                 android:text="Tab2"
    38                 android:textColor="@color/unselect"/>
    39         </LinearLayout>
    40 
    41         <LinearLayout
    42             android:layout_width="match_parent"
    43             android:layout_height="2dip"
    44             android:layout_gravity="bottom"
    45             android:orientation="vertical"
    46             android:paddingBottom="3dip"
    47             android:background="#ddd">
    48 
    49             <ImageView
    50                 android:id="@+id/imfImgButtomLine"
    51                 android:layout_width="40dip"
    52                 android:layout_height="2dip"
    53                 android:scaleType="matrix"
    54                 android:src="@color/select" />
    55         </LinearLayout>
    56     </LinearLayout>
    57 
    58     <android.support.v4.view.ViewPager
    59         android:id="@+id/imfVpContent"
    60         android:layout_width="wrap_content"
    61         android:layout_height="wrap_content"
    62         android:layout_gravity="center"
    63         android:layout_weight="1.0"
    64         android:flipInterval="30"
    65         android:persistentDrawingCache="animation" />
    66         
    67 
    68 </LinearLayout>

    这里为了兼容,ViewPager也是用了support.v4里面的视图,导航的条子的宽度这里是乱设的,因为它到时的宽度会在java代码中进行设置。还有颜色呢只是在color.xml里面定义的颜色而已

    Java文件就不打算完全贴出来,因为这个可以用在碎片里面,也可以用在活动里面,我就用在了碎片里面。

    在构造碎片的方法里面或者构造视图的方法里面,依次调用下面定义的方法

     1     private void IniWidth()
     2     {
     3         DisplayMetrics dm=new DisplayMetrics();
     4         getActivity().getWindowManager().getDefaultDisplay().getMetrics(dm);
     5         int screenW = dm.widthPixels;
     6         buttomLine=(ImageView)view.findViewById(R.id.domfImgButtomLine);
     7         buttomLine.getLayoutParams().width=screenW/5;
     8         buttomLine.setLayoutParams(buttomLine.getLayoutParams());
     9         
    10         buttomLineWidth=buttomLine.getLayoutParams().width;
    11         offset = (int) ((screenW / 5.0 - buttomLineWidth) / 2);
    12 
    13         positionOne = (int) (screenW / 5.0);
    14         positionTwo = positionOne * 2;
    15         positionThree=positionOne * 3;
    16         positionFour=positionOne * 4;
    17     }

    这个方法先获取获取当前屏幕的宽度,再通过宽度对小条的吃长度进行设置,最后用到的几个position是后面在给小条动画效果时用到的值,它们都是int类型,记录着每个导航标题的位置。

     1     private void IniViews()
     2     {
     3         lbCheck=(TextView)view.findViewById(R.id.domfLbCheck);
     4         lbPublish=(TextView)view.findViewById(R.id.domfLbPublish);
     5         lbQuery=(TextView)view.findViewById(R.id.domfLbQuery);
     6         lbRecommand=(TextView)view.findViewById(R.id.domfLbRecommand);
     7         lbSend=(TextView)view.findViewById(R.id.domfLbSend);
     8 
     9         
    10         lbQuery.setOnClickListener(new MyOnClickListener(0));
    11         lbCheck.setOnClickListener(new MyOnClickListener(1));
    12         lbPublish.setOnClickListener(new MyOnClickListener(2));
    13         lbSend.setOnClickListener(new MyOnClickListener(3));
    14         lbRecommand.setOnClickListener(new MyOnClickListener(4));
    15     }

    视图设置,给相应的导航标题对象添加引用,以及绑定事件,绑定事件目的在于点击文字时会切换到相应的页面中去,事件的定义如下

     1     class MyOnClickListener implements View.OnClickListener {
     2         private int index = 0;
     3 
     4         public MyOnClickListener(int i) {
     5             index = i;
     6         }
     7 
     8         @Override
     9         public void onClick(View v) {
    10             mPager.setCurrentItem(index);
    11         }
    12 };

    最后设置ViewPager了

     1     private void IniViewPager()
     2     {
     3         mPager=(ViewPager)view.findViewById(R.id.domfVpContent);
     4         
     5         
     6         ArrayList<Fragment> fragLst=new ArrayList<Fragment>();
     7         checkFrag =new DataOptionCheckFragment();
     8         publishFrag =new DataOptionPublishFragment();
     9         queryFrag =new DataOptionQueryFragment();
    10         recommandFrag =new DataOptionRecommandFragment();
    11         sendFrag =new DataOptionSendFragment();
    12         fragLst.add(queryFrag);
    13         fragLst.add(checkFrag);
    14         fragLst.add(publishFrag);
    15         fragLst.add(sendFrag);
    16         fragLst.add(recommandFrag);
    17         
    18         adapter=new MyViewPageAdapter(getActivity().getSupportFragmentManager(),fragLst);
    19         mPager.setAdapter(adapter);
    20         mPager.setCurrentItem(0);
    21         mPager.setOnPageChangeListener(new MyOnPageChangeListener());
    22         mPager.setCurrentItem(0);
    23     }

    这里主要是设置构造相应的碎片,然后添加到相应的adapter里面,加入到ViewPager里面,重点在于PageChange事件的定义

      1     class MyOnPageChangeListener implements OnPageChangeListener {
      2 
      3         @Override
      4         public void onPageScrollStateChanged(int arg0) {
      5             // TODO Auto-generated method stub
      6 
      7         }
      8 
      9         @Override
     10         public void onPageScrolled(int arg0, float arg1, int arg2) {
     11             // TODO Auto-generated method stub
     12 
     13         }
     14 
     15         @Override
     16         public void onPageSelected(int selectedIndex) {
     17             
     18             
     19             Animation animation=null;
     20             if(selectedIndex==currIndex)
     21             {
     22                 
     23             }
     24             switch (selectedIndex) {
     25             case 0:
     26                 if (currIndex == 1) {
     27                     animation = new TranslateAnimation(positionOne, 0, 0, 0);
     28                     lbCheck.setTextColor(resources.getColor(R.color.unselect));
     29                 } else if (currIndex == 2) {
     30                     animation = new TranslateAnimation(positionTwo, 0, 0, 0);
     31                     lbPublish.setTextColor(resources.getColor(R.color.unselect));
     32                 } else if (currIndex == 3) {
     33                     animation = new TranslateAnimation(positionThree, 0, 0, 0);
     34                     lbSend.setTextColor(resources.getColor(R.color.unselect));
     35                 }else if (currIndex == 4) {
     36                     animation = new TranslateAnimation(positionFour, 0, 0, 0);
     37                     lbRecommand.setTextColor(resources.getColor(R.color.unselect));
     38                 } else if(selectedIndex==currIndex){
     39                     animation=new TranslateAnimation(0, 0, 0, 0);
     40                     lbQuery.setTextColor(resources.getColor(R.color.unselect));
     41                 }
     42                 lbQuery.setTextColor(resources.getColor(R.color.select));
     43                 break;
     44             case 1:
     45                 if (currIndex == 0) {
     46                     animation = new TranslateAnimation(offset, positionOne, 0, 0);
     47                     lbQuery.setTextColor(resources.getColor(R.color.unselect));
     48                 } else if (currIndex == 2) {
     49                     animation = new TranslateAnimation(positionTwo, positionOne, 0, 0);
     50                     lbPublish.setTextColor(resources.getColor(R.color.unselect));

    125             animation.setDuration(300);
    126             buttomLine.startAnimation(animation);
    127             
    128         }
    129         
    130     }

    这里根据之前选中的标题是哪个,确定要把小滑块从原本位置移动到新位置上,把原本选中颜色的文字变回不选中,把新选中文字的颜色更替。

    设置ViewPager时还涉及到一个adapter的定义,代码如下

     1 public class MyViewPageAdapter extends FragmentPagerAdapter {
     2     private ArrayList<Fragment> arrayList;
     3     
     4     public MyViewPageAdapter(FragmentManager fm) {
     5         super(fm);
     6         // TODO Auto-generated constructor stub
     7     }
     8 
     9     public MyViewPageAdapter(FragmentManager fm,ArrayList<Fragment> arrayList)
    10     {
    11         super(fm);
    12         this.arrayList=arrayList;
    13     }
    14 
    15     
    16     @Override
    17     public Fragment getItem(int position) {
    18         // TODO Auto-generated method stub
    19         return arrayList.get(position);
    20     }
    21 
    22     @Override
    23     public int getCount() {
    24         // TODO Auto-generated method stub
    25         return arrayList.size();
    26     }
    27     
    28     @Override
    29     public int getItemPosition(Object object) {
    30         return POSITION_NONE;
    31     }
    32 }

    有个争议的地方,就是对public Object instantiateItem (ViewGroup container, int position)方法的重写,在网上看对这个方法重写后,多次切换ViewPager之后内容就会被清空掉,但是我重写了之后内容才不会被清空,有次还尝试了无论有没有重写照样被清空。

    底部Tab导航

    这个用的是TabHost了,个人认为主要的是TabHost和TabWidget,而主要还是靠TabWidget这部分把Tab的效果呈现出来,而页面的内容最终还是靠碎片来实现,这里可以用FrameLayout显示一个碎片,也可以通过ViewPager显示,布局文件如下

    <?xml version="1.0" encoding="utf-8"?>
    <TabHost
        xmlns:android="http://schemas.android.com/apk/res/android"
        android:id="@android:id/tabhost"
        android:layout_width="match_parent"
        android:layout_height="match_parent">
     
        <LinearLayout
            android:orientation="vertical"
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:id="@+id/tabEnableLayout">
    
            
            <FrameLayout
                android:id="@+id/realtabcontent"
                android:layout_width="match_parent"
                android:layout_height="0dp"
                android:layout_weight="1"/>  
             
             
            <TabWidget
                android:id="@android:id/tabs"
                android:layout_width="match_parent"
                android:layout_height="wrap_content"
                android:tabStripEnabled="false"
                android:background="#04508b"
                android:layout_weight="0"/>
             
        </ LinearLayout >
    </TabHost>

    然后java文件构造的方法中按顺序调用下面定义的方法

     1     //设置tab选项的内容
     2     private void SetViews()
     3     {
     4         fm=this.getActivity().getSupportFragmentManager();
     5         
     6         tabHost=(TabHost)contentView. findViewById(android.R.id.tabhost);
     7         tabWidget=(TabWidget)contentView. findViewById(android.R.id.tabs);
     8         LinearLayout layout=(LinearLayout)tabHost.getChildAt(0);
     9         TabWidget tw=(TabWidget)layout.getChildAt(1);
    10         
    11         relative1=(RelativeLayout)LayoutInflater.from(this.getActivity()).inflate(R.layout.tab_indicator_item, tw, false);
    12         ((ImageView)relative1.getChildAt(0)).setBackgroundResource(R.drawable.selector_tab_home);
    13         ((TextView)relative1.getChildAt(1)).setText("首页");
    14         
    15         relative2=(RelativeLayout)LayoutInflater.from(this.getActivity()).inflate(R.layout.tab_indicator_item, tw, false);
    16         ((ImageView)relative2.getChildAt(0)).setBackgroundResource(R.drawable.selector_tab_data);
    17         ((TextView)relative2.getChildAt(1)).setText("数据");
    18         
    19         relative3=(RelativeLayout)LayoutInflater.from(this.getActivity()).inflate(R.layout.tab_indicator_item, tw, false);
    20         ((ImageView)relative3.getChildAt(0)).setBackgroundResource(R.drawable.selector_tab_room);
    21         ((TextView)relative3.getChildAt(1)).setText("站房");
    22         
    23         relative4=(RelativeLayout)LayoutInflater.from(this.getActivity()).inflate(R.layout.tab_indicator_item, tw, false);
    24         ((ImageView)relative4.getChildAt(0)).setBackgroundResource(R.drawable.selector_tab_more);
    25         ((TextView)relative4.getChildAt(1)).setText("更多");
    26         
    27         indexFragment=new IndexFragment();
    28         dataOptionFragment=new DataOptionFragment();
    29         roomEnvFragment =new RoomEnvFragment();
    30         moreFragment=new MoreFragment();
    31         
    32     }

    这里主要是获取了TabWidget,然后把逐个标签设置进去,标签的内容也是通过布局文件来设置。

     1 private void SetTabHost()
     2     {
     3         tabHost.setup();
     4         TabHost.OnTabChangeListener tabChangeListener = new TabHost.OnTabChangeListener(){    
     5             @Override
     6             public void onTabChanged(String arg0) {
     7                 
     8                 catch(Exception ex)
     9                 {}
    10                 
    11                 if(arg0.equalsIgnoreCase("Home")){
    12                     ChangeFragment(indexFragment);
    13                     SELECT_TAB=1;
    14                 }
    15                 
    16                 else if(arg0.equalsIgnoreCase("Data")){
    17                     ChangeFragment(dataOptionFragment);
    18                     SELECT_TAB=2;
    19                 }
    20                 
    21                 else if(arg0.equalsIgnoreCase("Room")){
    22                     ChangeFragment(roomEnvFragment);
    23                     SELECT_TAB=3;
    24                 }
    25                 else if(arg0.equalsIgnoreCase("More")){
    26                     ChangeFragment(moreFragment);
    27                     SELECT_TAB=4;
    28                 }
    29                 
    30                 else
    31                 {
    32                     switch (SELECT_TAB) {
    33                     default:
    34                     case 1:
    35                         ChangeFragment(indexFragment);
    36                         break;
    37                     case 2:
    38                         ChangeFragment(dataOptionFragment);
    39                         break;
    40                     case 3:
    41                         ChangeFragment(roomEnvFragment);
    42                         break;
    43                     case 4:
    44                         ChangeFragment(moreFragment);
    45                         break;
    46                     }
    47                 }
    48             }
    49         };
    50         tabHost.setCurrentTab(0);
    51         tabHost.setOnTabChangedListener(tabChangeListener);
    52         IniTab();
    53         tabHost.setCurrentTab(0);
    54     }

    这里大部分代码都是定义Tab切换的事件,因为在Android中的TabHost跟之前在WinFor中的TabControl那样,标签切换了,内容跟着切换。切换时调用了一个方法,处理碎片的切换

    1     private void ChangeFragment(Fragment frag)
    2     {
    3         ft= fm.beginTransaction();
    4         ft.setTransition(FragmentTransaction.TRANSIT_FRAGMENT_FADE);
    5         ft.replace(R.id.realtabcontent, frag);
    6         ft.commit();
    7     }

    还有另一个方法是真的把Tab添加都TabHost里面去了

     1     //增添Tab的内容
     2     private void IniTab()
     3     {
     4         TabSpec tSpecHome=tabHost.newTabSpec("Home");
     5         TabSpec tSpecData=tabHost.newTabSpec("Data");
     6         TabSpec tSpecRoom=tabHost.newTabSpec("Room");
     7         TabSpec tSpecMore=tabHost.newTabSpec("More");
     8         
     9         tSpecHome.setIndicator(relative1);
    10         tSpecHome.setContent(new MyTabContent(this.getActivity().getBaseContext()));
    11         tSpecData.setIndicator(relative2);
    12         tSpecData.setContent(new MyTabContent(this.getActivity().getBaseContext()));
    13         tSpecRoom.setIndicator(relative3);
    14         tSpecRoom.setContent(new MyTabContent(this.getActivity().getBaseContext()));
    15         tSpecMore.setIndicator(relative4);
    16         tSpecMore.setContent(new MyTabContent(this.getActivity().getBaseContext()));
    17         
    18         tabHost.addTab(tSpecHome);
    19         tabHost.addTab(tSpecData);
    20         tabHost.addTab(tSpecRoom);
    21         tabHost.addTab(tSpecMore);
    22         
    23     }

    侧栏菜单

    这个感觉比较简单,但是效果没那么好,主要用到的是FrameLayout布局(或者RelativeLayout布局)和ListView,因为FrameLayout只能让内容显示在左上角(RelativeLayout默认也是把内容显示在左上角),所以把ListView设置在FrameLayout(或RelativeLayout)最下面就可以了。

     1 <RelativeLayout
     2     xmlns:android="http://schemas.android.com/apk/res/android"
     3     android:layout_width="fill_parent"
     4     android:layout_height="fill_parent"
     5     >
     6      <RelativeLayout 
     7            android:id="@+id/divTitle"
     8             android:layout_width="fill_parent"
     9             android:layout_height="45dp"
    10             android:orientation="horizontal"
    11             android:background="#007ACC"
    12             >
    13             <TextView
    14                 android:layout_width="wrap_content"
    15                 android:layout_height="wrap_content"
    16                 android:textSize="22dp"
    17                 android:layout_centerInParent="true"
    18                 android:textColor="@android:color/white"
    19                 android:text="@string/app_name"
    20                 />
    21                 <Button
    22                     android:layout_width="wrap_content"
    23                     android:layout_height="wrap_content"
    24                     android:layout_alignParentRight="true"
    25                     android:layout_centerVertical="true"
    26                     android:text="刷新"
    27                     android:id="@+id/titleBtnRefresh"
    28                     />
    29 
    30         </RelativeLayout>
    31     
    32         
    33     <fragment 
    34         android:id="@+id/titles"
    35         android:layout_width="wrap_content"
    36         android:layout_height="match_parent"
    37         android:layout_weight="1"
    38         class="com.sysu.cityenv.androidapp.Fragments.TabHostFragment"/>   
    39     </LinearLayout>
    40     
    41             
    42      <ListView
    43         android:id="@+id/left_menu"
    44         android:layout_height="fill_parent"
    45         android:layout_width="120dp"
    46         android:background="#F0F0F0"/>   
    47           
    48   
    49         
    50 </RelativeLayout>

    ListView设置的代码就不列举了,拉出侧栏的代码是通过触控事件来实现的,在点击下去的时候记录开始位置,到提起来的时候就判断移动的方向,从而把ListView设置成显示和隐藏

     1     @Override
     2     public boolean onTouchEvent(MotionEvent event)
     3     {
     4         float xDelta=(float) Math.abs(mPostion-event.getX());
     5         if(event.getAction()==MotionEvent.ACTION_DOWN){
     6             mPostion= event.getX();
     7             mPositionY=event.getY();
     8             
     9         }
    10         if(event.getAction()==MotionEvent.ACTION_UP&&xDelta>70)
    11         {
    12             if(xDelta>Math.abs(mPositionY-event.getY())){
    13                 
    14                 boolean isVisiable=leftMenu.getVisibility()==View.VISIBLE;
    15                 if(mPostion>event.getX()&&isVisiable)     Hide();
    16                 else if(mPostion<event.getX()&&mPostion<=sWidth*0.1)    Show();
    17             }
    18         }
    19             
    20         return super.onTouchEvent(event);
    21     }

    不过侧栏滑出来了,后面的内容还是会有事件响应的,就算在这里把返回值设成false也没用(true表明在事件冒泡中还需要处理,false则表示不需要处理了),因为在整个事件冒泡过程中,这个OnTouch的时间在最后才触发,那只能把后面视图作处理,让它的返回是false,我的处理是这样子的,把ListView下面的内容放在一个Layout的布局中去,那个Layout是自己拓展某个Layout视图,重写它的onInterceptTouchEvent方法,让它在适当的时候返回false,不对触控有响应,那么点击事件也没响应了,因为Click事件是包在了两个Touch事件里面的(DOWN和UP)。

     1     @Override
     2     public boolean onTouchEvent(MotionEvent event)
     3     {
     4         float xDelta=(float) Math.abs(mPostion-event.getX());
     5         if(event.getAction()==MotionEvent.ACTION_DOWN){
     6             mPostion= event.getX();
     7             mPositionY=event.getY();
     8             
     9             if(mPostion<=sWidth*0.1)
    10                 ((MyLinearLayout)findViewById(R.id.tabEnableLayout)).SetControlEnable(false);
    11         }
    12         if(event.getAction()==MotionEvent.ACTION_UP&&xDelta>70)
    13         {
    14             if(xDelta>Math.abs(mPositionY-event.getY())){
    15                 
    16                 boolean isVisiable=leftMenu.getVisibility()==View.VISIBLE;
    17                 if(mPostion>event.getX()&&isVisiable)     Hide();
    18                 else if(mPostion<event.getX()&&mPostion<=sWidth*0.1)    Show();
    19             }
    20         }
    21         else if(event.getAction()==MotionEvent.ACTION_UP&&mPostion<=sWidth*0.1)
    22         {
    23             ((MyLinearLayout)findViewById(R.id.tabEnableLayout)).SetControlEnable(true);
    24         }
    25             
    26         return super.onTouchEvent(event);
    27     }

    代码就成这样子,但是这样有个弊端是,滑动的距离太小的时候,侧栏没显示出来,但是侧栏下面的内容已经停止了事件响应,暂时没好办法去处理。
