1 普通对话框（喜欢，不喜欢，一般）

2 输入“文本”后确定或取消

3 对话框退出功能，确定是否退出

4 带有单选按钮的弹出框使用 

5 以列表形式，显示单选列表 

6 以复选框的形式，展示的对话框 

 

一、调用各种对话框的按钮xml

 

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:orientation="vertical" >

    <Button
        android:id="@+id/Button01"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:text="投票选择" >
    </Button>

    <Button
        android:id="@+id/Button02"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:text="输入确定" >
    </Button>

    <Button
        android:id="@+id/Button03"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:text="确定退出" >
    </Button>

    <Button
        android:id="@+id/Button04"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:text="单选按钮组" >
    </Button>

    <Button
        android:id="@+id/Button05"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:text="单选列表对话框" >
    </Button>
    <Button
        android:id="@+id/Button06"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:text="复选列表对话框" >
    </Button>
    
    
</LinearLayout>

 

二、Activity的代码 

 

package com.example.fragmentdemo1;  
  
import android.app.Activity;
import android.app.AlertDialog;
import android.app.AlertDialog.Builder;
import android.content.Context;
import android.content.DialogInterface;

import android.view.LayoutInflater;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.EditText;
import android.widget.Toast;
  
//对话框测试  
//参考  http://blog.youkuaiyun.com/andie_guo/article/details/14145135
public class DialogActivity extends Activity {

    EditText editText;
    
    /** Called when the activity is first created. */  
    @Override  
    public void onCreate(Bundle savedInstanceState) {  
        super.onCreate(savedInstanceState);  
        setContentView(R.layout.dialog);  
        
        //定义按钮  
        btnShowDialog=(Button)this.findViewById(R.id.Button01);  
        btnShowDialog.setOnClickListener(new ClickEvent());

        singleChoseListBtn=(Button)this.findViewById(R.id.Button05);  
        singleChoseListBtn.setOnClickListener(new ClickEvent());  

        checkboxChoseListBtn=(Button)this.findViewById(R.id.Button06);  
        checkboxChoseListBtn.setOnClickListener(new ClickEvent()); 
        
    }  
      
      
    //统一处理按键事件  
    class ClickEvent implements OnClickListener{
        @Override

三、array.xml的数据列表

 

<?xml version="1.0" encoding="utf-8"?>
<resources>
  <string-array name="hobby">        
     <item>游泳</item>            
     <item>打篮球</item>            
     <item>登山</item>        
  </string-array>
</resources>
