xml布局如下：

<?xml version="1.0" encoding="utf-8"?>
<linearlayout xmlns:android="http://schemas.android.com/apk/res/android"
 xmlns:app="http://schemas.android.com/apk/res-auto"
 xmlns:tools="http://schemas.android.com/tools"
 android:layout_width="match_parent"
 android:layout_height="match_parent"
 tools:context="com.example.lyp1020k.lv.mainactivity"
 android:orientation="vertical">
 
 <button
 android:id="@+id/button1"
 android:text="列表框"
 android:onclick="showlist"
 android:layout_width="match_parent"
 android:layout_height="wrap_content" />
 
 <button
 android:id="@+id/button2"
 android:text="单选列表"
 android:onclick="showsinglealertdialog"
 android:layout_width="match_parent"
 android:layout_height="wrap_content" />
 
 <button
 android:id="@+id/button3"
 android:text="多选按钮"
 android:onclick="showmutilalertdialog"
 android:layout_width="match_parent"
 android:layout_height="wrap_content" />
 
</linearlayout>
