一、Dilog使用实例

activity_main.xml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" >    <TextView        android:layout_width="wrap_content"        android:layout_height="wrap_content"        android:textSize="10pt"        android:text="对话框测试" />    <Button         android:id="@+id/simpleButton"        android:layout_width="fill_parent"        android:layout_height="60dp"        android:text="简单对话框"/>    <Button         android:id="@+id/listButton"        android:layout_width="fill_parent"        android:layout_height="60dp"        android:text="列表对话框"/>    <Button         android:id="@+id/multiButton"        android:layout_width="fill_parent"        android:layout_height="60dp"        android:text="多选对话框"/>    <Button         android:id="@+id/loginButton"        android:layout_width="fill_parent"        android:layout_height="60dp"        android:text="登录对话框"/>    <Button         android:id="@+id/timerButton"        android:layout_width="fill_parent"        android:layout_height="60dp"        android:text="时间对话框"/>    <Button         android:id="@+id/popupButton"        android:layout_width="fill_parent"        android:layout_height="60dp"        android:text="弹出对话框"/>    <Button         android:id="@+id/customButton"        android:layout_width="fill_parent"        android:layout_height="60dp"        android:text="自定义对话框"/></LinearLayout>
