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>

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>
