安卓学习-界面-ui-对话框

1.最简单的消息提示

 

 Button btn=(Button)findViewById(R.id.button1);
    btn.setOnClickListener(new OnClickListener() {
        public void onClick(View v) {
            AlertDialog d=new AlertDialog.Builder(MainActivity.this)
            .setTitle("这是标题")
        //图标
        .setIcon(R.drawable.ic_launcher)
        .setMessage("消息提示")
        .setNegativeButton("左按钮", null)
        .setNeutralButton("中按钮", null)
        .setPositiveButton("右按钮", null)            
        .create();
        d.show();
    }
});

 2.简单列表窗口

public class MainActivity extends Activity {

    String[] items=new String[]{"苹果","鸭梨","桔子","香蕉"};
    
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        
         Button btn=(Button)findViewById(R.id.button1);
            btn.setOnClickListener(new OnClickListener() {
                public void onClick(View v) {
                    AlertDialog d=new AlertDialog.Builder(MainActivity.this)
                    .setTitle("水果列表")
                    //图标
                    .setIcon(R.drawable.ic_launcher)
                    .setItems(items, new DialogInterface.OnClickListener() {
                            public void onClick(DialogInterface dialog, int which) {
                            Toast.makeText(MainActivity.this, items[which], Toast.LENGTH_SHORT).show();                            
                        }
                    })
                    .setNeutralButton("我知道了", new DialogInterface.OnClickListener() {
        
                        public void onClick(DialogInterface dialog, int which) {
                            Toast.makeText(MainActivity.this,"我知道了", Toast.LENGTH_SHORT).show();    
                        }
                    })
                    .create();
                d.show();
            }
        });
    }
}

3.单选列表框

public class MainActivity extends Activity {

    int selIndex=0;
    String[] items=new String[]{"苹果","鸭梨","桔子","香蕉"};
    
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        
         Button btn=(Button)findViewById(R.id.button1);
            btn.setOnClickListener(new OnClickListener() {
                public void onClick(View v) {
                    AlertDialog d=new AlertDialog.Builder(MainActivity.this)
                    .setTitle("请选择")
                    //图标
                    .setIcon(R.drawable.ic_launcher)
                    .setSingleChoiceItems(items, selIndex, new DialogInterface.OnClickListener() {
                        public void onClick(DialogInterface dialog, int which) {
                            selIndex=which;
                            Toast.makeText(MainActivity.this, "你选择的是："+items[which], Toast.LENGTH_SHORT).show();            
                        }
                    })
                    .setNeutralButton("确定", new DialogInterface.OnClickListener() {
                        public void onClick(DialogInterface dialog, int which) {
                            Toast.makeText(MainActivity.this,"确定，选择的的是"+items[selIndex], Toast.LENGTH_SHORT).show();    
                        }
                    })
                    .setPositiveButton("取消", new DialogInterface.OnClickListener() {
                        public void onClick(DialogInterface dialog, int which) {
                            Toast.makeText(MainActivity.this,"取消", Toast.LENGTH_SHORT).show();    
                        }
                    })
                    .create();
                d.show();
            }
        });
    }
}

 4.多选

public class MainActivity extends Activity {

    int selIndex=0;
    String[] items=new String[]{"苹果","鸭梨","桔子","香蕉"};
    boolean[] selItems=new boolean[]{false,false,true,true};
    
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        
         Button btn=(Button)findViewById(R.id.button1);
            btn.setOnClickListener(new OnClickListener() {
                public void onClick(View v) {
                    AlertDialog d=new AlertDialog.Builder(MainActivity.this)
                    .setTitle("请选择")
                    //图标
                    .setIcon(R.drawable.ic_launcher)
                    .setMultiChoiceItems(items,selItems, new DialogInterface.OnMultiChoiceClickListener() {
                        public void onClick(DialogInterface dialog, int which, boolean isChecked) {
                            if(isChecked){
                                Toast.makeText(MainActivity.this, "你选择了："+items[which], Toast.LENGTH_SHORT).show();
                                selItems[which]=isChecked;
                            }
                        }
                    })
                    .setNeutralButton("确定", new DialogInterface.OnClickListener() {
                        public void onClick(DialogInterface dialog, int which) {
                            String str="";
                            for(int i=0;i<selItems.length;i++){
                                if(selItems[i]){
                                    str=str+items[i]+",";
                                }
                            }
                            Toast.makeText(MainActivity.this,"确定，选择的的是"+str, Toast.LENGTH_SHORT).show();    
                        }
                    })
                    .setPositiveButton("取消", new DialogInterface.OnClickListener() {
                        public void onClick(DialogInterface dialog, int which) {
                            Toast.makeText(MainActivity.this,"取消", Toast.LENGTH_SHORT).show();    
                        }
                    })
                    .create();
                d.show();
            }
        });
    }
}

5.自定义adapter

 

activity_main.xml

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context="${relativePackage}.${activityClass}" >

    <Button
        android:id="@+id/button1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignParentLeft="true"
        android:text="Button" />

</RelativeLayout>

item.xml

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent" >

    <ImageView
        android:id="@+id/imageView1"
        android:layout_width="50dp"
        android:layout_height="50dp"
        android:layout_alignParentLeft="true"
        android:layout_alignParentTop="true"
        android:layout_marginLeft="25dp"
        android:layout_marginTop="16dp" />

    <TextView
        android:id="@+id/textView1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignTop="@+id/imageView1"
        android:layout_marginLeft="14dp"
        android:layout_toRightOf="@+id/imageView1"
        android:text="Large Text"
        android:textAppearance="?android:attr/textAppearanceLarge" />

</RelativeLayout>

MainActivity.java

public class MainActivity extends Activity {

    int selIndex=0;
    SimpleAdapter sa;
    String[] names=new String[]{"苹果","鸭梨","桔子","香蕉"};
    int[] res=new int[]{R.drawable.pic1,R.drawable.pic2,R.drawable.pic3,R.drawable.pic4};
    ArrayList<HashMap<String,Object>> items=new ArrayList<HashMap<String,Object>>();
    
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        
        for(int i=0;i<names.length;i++){
            HashMap<String,Object> map=new HashMap<String,Object>();
            map.put("name", names[i]);
            map.put("res", res[i]);
            items.add(map);
        }
    
        sa=new SimpleAdapter(MainActivity.this,items,
                R.layout.item,new String[]{"name","res"},new int[]{R.id.textView1,R.id.imageView1});

         Button btn=(Button)findViewById(R.id.button1);
            btn.setOnClickListener(new OnClickListener() {
                public void onClick(View v) {
                    AlertDialog d=new AlertDialog.Builder(MainActivity.this)
                    .setTitle("请选择")
                    //图标
                    .setIcon(R.drawable.ic_launcher)
                    .setAdapter(sa, new DialogInterface.OnClickListener() {
                        @Override
                        public void onClick(DialogInterface dialog, int which) {
                            Toast.makeText(MainActivity.this,"选择的的是"+names[which], Toast.LENGTH_SHORT).show();
                        }
                    })
                    .setPositiveButton("取消", new DialogInterface.OnClickListener() {
                        public void onClick(DialogInterface dialog, int which) {
                            Toast.makeText(MainActivity.this,"取消", Toast.LENGTH_SHORT).show();    
                        }
                    })
                    .create();
                d.show();
                
                }
        });
    }
}

 6.自定义view

login.xml

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent" >

    <TextView
        android:id="@+id/textView1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignParentLeft="true"
        android:layout_alignParentTop="true"
        android:layout_marginLeft="15dp"
        android:layout_marginTop="22dp"
        android:text="用户名"
        android:textAppearance="?android:attr/textAppearanceLarge" />

    <TextView
        android:id="@+id/textView2"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignLeft="@+id/textView1"
        android:layout_below="@+id/textView1"
        android:layout_marginTop="21dp"
        android:text="密码"
        android:textAppearance="?android:attr/textAppearanceLarge" />

    <EditText
        android:id="@+id/editText1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignBaseline="@+id/textView1"
        android:layout_alignBottom="@+id/textView1"
        android:layout_toRightOf="@+id/textView1"
        android:ems="10" >

        <requestFocus />
    </EditText>

    <EditText
        android:id="@+id/editText2"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignBottom="@+id/textView2"
        android:layout_alignLeft="@+id/editText1"
        android:ems="10" />

</RelativeLayout>

MainActivity.java

public class MainActivity extends Activity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

         Button btn=(Button)findViewById(R.id.button1);
            btn.setOnClickListener(new OnClickListener() {
                public void onClick(View v) {
                    View view=LayoutInflater.from(MainActivity.this).inflate(R.layout.login,null);
                    AlertDialog d=new AlertDialog.Builder(MainActivity.this)
                    .setTitle("登录窗口")
                    //图标
                    .setIcon(R.drawable.ic_launcher)
                    .setView(view)
                    .setNegativeButton("登录", new DialogInterface.OnClickListener() {
                        public void onClick(DialogInterface dialog, int which) {
                            Toast.makeText(MainActivity.this,"登录", Toast.LENGTH_SHORT).show();    
                        }
                    })
                    .setPositiveButton("取消", new DialogInterface.OnClickListener() {
                        public void onClick(DialogInterface dialog, int which) {
                            Toast.makeText(MainActivity.this,"取消", Toast.LENGTH_SHORT).show();    
                        }
                    })
                    .create();
                d.show();
                
                }
        });
    }
}

 7.将activity定义为窗口

定义一个ExitActivity窗口供主窗口调用

exit.xml

<?xml version="1.0" encoding="UTF-8"?>
    <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
        android:id="@+id/exit_layout"
        android:layout_width="280dp"
        android:layout_height="wrap_content"
        android:gravity="center_horizontal"
        android:orientation="vertical"
        android:background="@drawable/confirm_dialog_bg2" >

        <TextView
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_marginTop="4dp"
            android:padding="5dp"
            android:textColor="#333"
            android:textSize="20sp"
            android:text="退出微信" />
        
        <TextView
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:textColor="#333"
            android:layout_marginTop="1dp"
            android:padding="10dp"
            android:textSize="16sp"
            android:gravity="center_horizontal"
            android:text="退出后，你将收不到新的消
息.确定要退出？" /> 
        

        <LinearLayout
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"           
            android:layout_marginTop="33dp"
            android:layout_marginBottom="8dp"
             >
            
            <Button
              android:id="@+id/exitBtn0"
              android:layout_width="110dp"
              android:layout_height="wrap_content"
              android:text="是"
              android:textSize="16sp"
              android:textColor="#fff"
              android:background="@drawable/btn_style_green"
              android:gravity="center"
              android:onClick="exitbutton0"
              />
            
            <Button
              android:id="@+id/exitBtn1"
              android:layout_width="110dp"
              android:layout_height="wrap_content"
              android:layout_marginLeft="10dp"
              android:text="否"
              android:textSize="16sp"
              android:textColor="#333"
              android:background="@drawable/btn_style_white"
              android:gravity="center"
              android:onClick="exitbutton1"
              />
        </LinearLayout>

    </LinearLayout>

ExitActivity.java

package com.example.popupwindow;

import android.app.Activity;
import android.os.Bundle;
import android.view.MotionEvent;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.LinearLayout;
import android.widget.Toast;

public class ExitActivity extends Activity {
    LinearLayout layout;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.exit);

        layout = (LinearLayout) findViewById(R.id.exit_layout);
        layout.setOnClickListener(new OnClickListener() {
            @Override
            public void onClick(View v) {
                // TODO Auto-generated method stub
                Toast.makeText(getApplicationContext(), "提示：点击窗口外部关闭窗口！",
                        Toast.LENGTH_SHORT).show();
            }
        });
    }

    @Override
    public boolean onTouchEvent(MotionEvent event) {
        finish();
        return true;
    }

    public void exitbutton1(View v) {
        this.finish();
    }

    public void exitbutton0(View v) {
        this.finish();
        MainActivity.instance.finish();// 关闭Main 这个Activity
    }
}

 样式MyDialogStyle

    <style name="MyDialogStyle">
         <!-- 窗口背景色 -->
         <item name="android:windowBackground">@android:color/transparent</item>
         <!-- Dialog的windowFrame框为无 -->
         <item name="android:windowFrame">@null</item>

         <item name="android:windowIsFloating">true</item>
         <!-- 窗口是否半透明——是（与第一条配合使用） -->
         <item name="android:windowIsTranslucent">true</item>
         <!-- 这个不设置的话，可能会出现边框黑线 -->
         <item name="android:windowContentOverlay">@null</item>
         <!-- 窗口弹出效果 -->
         <item name="android:windowAnimationStyle">@android:style/Animation.Dialog</item>
         <!-- 是否允许背景模糊 -->
         <item name="android:backgroundDimEnabled">true</item>
    </style>

修改AndroidManifest.xml

<activity android:name="ExitActivity" android:theme="@style/MyDialogStyle"></activity>

在主界面，用这个执行调用窗体

Intent intent=new Intent(MainActivity.this,ExitActivity.class);
startActivity(intent);

8.PopupWindow创建对话框,仿微信

activity_main.xml

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context="${relativePackage}.${activityClass}" >

    <Button
        android:id="@+id/button1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignParentRight="true"
        android:layout_alignParentTop="true"
        android:layout_marginRight="43dp"
        android:text="菜单" />
