在进行表单提交之前，一定会有用户的输入，输入就免不了一些提示和选择。本文就介绍一下通知对话框，多选对话框和单选对话框。

下面是主要代码：

<?xml version="1.0" encoding="utf-8"?><RelativeLayout 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:paddingBottom="@dimen/activity_vertical_margin"    android:paddingLeft="@dimen/activity_horizontal_margin"    android:paddingRight="@dimen/activity_horizontal_margin"    android:paddingTop="@dimen/activity_vertical_margin"    tools:context="com.example.wuxueyou.myfirstandroidapplication.MainActivity">    <Button        android:layout_width="wrap_content"        android:layout_height="wrap_content"        android:text="多选对话框"        android:id="@+id/button1"        android:layout_centerVertical="true"        android:layout_centerHorizontal="true" />    <Button        android:layout_width="wrap_content"        android:layout_height="wrap_content"        android:text="提示框"        android:id="@+id/button"        android:layout_above="@+id/button1"        android:layout_centerHorizontal="true"        android:layout_marginBottom="68dp" />    <Button        android:layout_width="wrap_content"        android:layout_height="wrap_content"        android:text="单选dialog"        android:id="@+id/button2"        android:layout_below="@+id/button1"        android:layout_alignLeft="@+id/button1"        android:layout_alignStart="@+id/button1"        android:layout_marginTop="61dp" /></RelativeLayout>
