Android各种对话框的使用

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

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>
