布局文件

<LinearLayout 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"    android:orientation="vertical"    tools:context=".MainActivity" >    <Button        android:onClick="click1"        android:layout_width="fill_parent"        android:layout_height="wrap_content"        android:text="确定取消对话框" />        <Button        android:onClick="click2"        android:layout_width="fill_parent"        android:layout_height="wrap_content"        android:text="单选对话框" />            <Button        android:onClick="click3"        android:layout_width="fill_parent"        android:layout_height="wrap_content"        android:text="多选对话框" />                <Button        android:onClick="click4"        android:layout_width="fill_parent"        android:layout_height="wrap_content"        android:text="进度条对话框" /></LinearLayout >

代码实现
