test1.xml
<?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="match_parent" android:layout_height="match_parent" android:orientation="vertical" > <LinearLayout android:layout_width="match_parent" android:layout_height="wrap_content"> <TextView android:layout_width="match_parent" android:layout_height="45dp" android:gravity="center" android:background="#4ADF2B" android:textColor="#ffffff" android:textSize="20dp" android:text="悦动" /> </LinearLayout> <LinearLayout android:layout_width="match_parent" android:layout_height="match_parent"> <ImageView android:layout_width="match_parent" android:background="@drawable/yuedong22" android:layout_height="match_parent" /> </LinearLayout> </LinearLayout>
Activity_text1.java要继承Fragment 跟上面test1.xml进行适配
package com.example.speed_app; import android.os.Bundle; import android.support.annotation.Nullable; import android.support.v4.app.Fragment; import android.view.LayoutInflater; import android.view.View; import android.view.ViewGroup; public class Activity_text1 extends Fragment{ @Override public View onCreateView(LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) { // TODO Auto-generated method stub View view = inflater.inflate(R.layout.text1, container,false); return view; } }
上面的Activity_text1.java 和 test1.xml双双多个 这里就弄一个，我的项目弄了多个 因为都是一样的方法
上面准备好了
接下来才是我们要去实现的
caidan_dibu.xml
<?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="match_parent" android:layout_height="match_parent" android:orientation="horizontal" > <RadioGroup android:id="@+id/radioGroup1" android:layout_width="match_parent" android:layout_height="60dp" android:orientation="horizontal" android:gravity="center"> <RadioButton android:id="@+id/radioButton1" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_weight="1" android:button="@null" android:checked="true" android:drawableTop="@drawable/ledong" android:gravity="center" android:textColor="@drawable/color" android:text="悦动" /> <RadioButton android:id="@+id/radioButton2" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_weight="1" android:drawableTop="@drawable/tiaozhan" android:button="@null" android:textColor="@drawable/color" android:text="挑战" android:gravity="center" /> <RadioButton android:id="@+id/radioButton3" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_weight="1" android:button="@null" android:drawableTop="@drawable/faxian" android:gravity="center" android:textColor="@drawable/color" android:text="发现" /> <RadioButton android:id="@+id/radioButton4" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_weight="1" android:button="@null" android:drawableTop="@drawable/quanz" android:text="圈子" android:textColor="@drawable/color" android:gravity="center" /> <RadioButton android:id="@+id/radioButton5" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_weight="1" android:button="@null" android:textColor="@drawable/color" android:drawableTop="@drawable/wo3" android:text="我" android:gravity="center" /> </RadioGroup> </LinearLayout>
结果图：
home.xml
<?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="match_parent" android:layout_height="match_parent" android:orientation="vertical" > <LinearLayout android:layout_width="match_parent" android:layout_height="wrap_content" android:layout_weight="1" > <android.support.v4.view.ViewPager //这个是一个v4包，这个包放在你要切换布局里面在下图的框里 android:id="@+id/vp" android:layout_width="match_parent" android:layout_height="match_parent" android:flipInterval="30" android:persistentDrawingCache="animation" /> </LinearLayout> <LinearLayout android:layout_width="match_parent" android:layout_height="wrap_content"> <include layout="@layout/caidan_dibu"/> </LinearLayout> </LinearLayout>
结果：
MyFragmentPagerAdapter.java 实现适配器
package com.example.speed_app; import java.util.List; import android.support.v4.app.Fragment; import android.support.v4.app.FragmentManager; import android.support.v4.app.FragmentStatePagerAdapter; //FragmentPagerAdapter是Android-support-v4支持包里面出现的一个新的适配器 public class MyFragmentPagerAdapter extends FragmentStatePagerAdapter { private FragmentManager fragmentManager; private List<Fragment> fragmentList; public MyFragmentPagerAdapter(FragmentManager fragmentManager,List<Fragment> fragmentList) { super(fragmentManager); this.fragmentManager = fragmentManager; this.fragmentList = fragmentList; } @Override public Fragment getItem(int arg0) { // TODO Auto-generated method stub return fragmentList.get(arg0); } @Override public int getCount() { // TODO Auto-generated method stub return fragmentList.size(); } }
Activity_home.java 要继承FragmentActivity
package com.example.speed_app; import java.util.ArrayList; import java.util.List; import android.graphics.Color; import android.graphics.drawable.Drawable; import android.os.Bundle; import android.support.v4.app.Fragment; import android.support.v4.app.FragmentActivity; import android.support.v4.app.FragmentManager; import android.support.v4.app.FragmentTransaction; import android.support.v4.view.ViewPager; import android.support.v4.view.ViewPager.OnPageChangeListener; import android.view.View; import android.view.View.OnClickListener; import android.view.animation.Animation; import android.view.animation.TranslateAnimation; import android.widget.RadioButton; public class Activity_home extends FragmentActivity{ private int currIndex;//记录滑动的第几个 private ViewPager viewPager;//ViewPager滚动功能 private List<Fragment> fragmentList;//一共有多少个Fragment集合 private RadioButton radioButton1,radioButton2,radioButton3,radioButton4,radioButton5; @Override protected void onCreate(Bundle savedInstanceState) { // TODO Auto-generated method stub super.onCreate(savedInstanceState); setContentView(R.layout.home); //z初始化 viewpager viewPager = (ViewPager) findViewById(R.id.vp); fragmentList = new ArrayList<Fragment>(); Fragment fragment1 = new Activity_text1();//滑动页面的布局1 Fragment fragment2 = new Activity_text2();//滑动页面的布局2 Fragment fragment3 = new Activity_text3();//滑动页面的布局3 Fragment fragment4 = new Activity_text4();//滑动页面的布局4 Fragment fragment5 = new Activity_text5();//滑动页面的布局5 fragmentList.add(fragment1);//添加到集合保存 fragmentList.add(fragment2);//添加到集合保存 fragmentList.add(fragment3);//添加到集合保存 fragmentList.add(fragment4);//添加到集合保存 fragmentList.add(fragment5);//添加到集合保存 //FragmentManager能够实现管理activity中fragment. 通过调用activity的getFragmentManager()取得它的实例 FragmentManager fragmentManager = getSupportFragmentManager();//V4的包 //FragmentPagerAdapter类 MyFragmentPagerAdapter pagerAdapter = new MyFragmentPagerAdapter(fragmentManager, fragmentList); viewPager.setAdapter(pagerAdapter); viewPager.setCurrentItem(0);//默认从第1个开始 也就是Activity_text1()这个Fragment开始 viewPager.setOnPageChangeListener(new OnPageChangeListener() { @Override public void onPageSelected(int arg0) { // TODO Auto-generated method stub //Animation animation = new TranslateAnimation(0,0,0,0); //animation.setFillAfter(true); currIndex = arg0;//获取目前滑动的坐标 radioButton1 = (RadioButton) findViewById(R.id.radioButton1); radioButton2 = (RadioButton) findViewById(R.id.radioButton2); radioButton3 = (RadioButton) findViewById(R.id.radioButton3); radioButton4 = (RadioButton) findViewById(R.id.radioButton4); radioButton5 = (RadioButton) findViewById(R.id.radioButton5); switch (arg0) { case 0: radioButton1.setChecked(true);//如果是0坐标，那radioButton1这个单选按钮为true，也就是点击状态 break; case 1: radioButton2.setChecked(true); break; case 2: radioButton3.setChecked(true); break; case 3: radioButton4.setChecked(true); break; case 4: radioButton5.setChecked(true); break; default: break; } } @Override public void onPageScrolled(int arg0, float arg1, int arg2) { } @Override public void onPageScrollStateChanged(int arg0) { } }); //下面可以通过点击radioButton按钮实现切换页面 radioButton1 = (RadioButton) findViewById(R.id.radioButton1); radioButton2 = (RadioButton) findViewById(R.id.radioButton2); radioButton3 = (RadioButton) findViewById(R.id.radioButton3); radioButton4 = (RadioButton) findViewById(R.id.radioButton4); radioButton5 = (RadioButton) findViewById(R.id.radioButton5); radioButton1.setOnClickListener(new OnClickListener() { @Override public void onClick(View v) { viewPager.setCurrentItem(0);//这个0代表坐标，但点击radioButton1这个按钮之后会显示坐标为0的页面也就是 Activity_text1() } }); radioButton2.setOnClickListener(new OnClickListener() { @Override public void onClick(View v) { viewPager.setCurrentItem(1);//这个1代表坐标，但点击radioButton1这个按钮之后会显示坐标为0的页面也就是 Activity_text2() } }); radioButton3.setOnClickListener(new OnClickListener() { @Override public void onClick(View v) { viewPager.setCurrentItem(2);//这个2代表坐标，但点击radioButton1这个按钮之后会显示坐标为0的页面也就是 Activity_text3() } }); radioButton4.setOnClickListener(new OnClickListener() { @Override public void onClick(View v) { viewPager.setCurrentItem(3);//这个3代表坐标，但点击radioButton1这个按钮之后会显示坐标为0的页面也就是 Activity_text4() } }); radioButton5.setOnClickListener(new OnClickListener() { @Override public void onClick(View v) { viewPager.setCurrentItem(4);//这个4代表坐标，但点击radioButton1这个按钮之后会显示坐标为0的页面也就是 Activity_text5() } }); } }
