（1）布局文件如下：

<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=".MainActivity" ><Buttonandroid:id="@+id/button1"android:layout_width="wrap_content"android:layout_height="wrap_content"android:layout_alignParentLeft="true"android:layout_alignParentTop="true"android:onClick="IntentTest"android:text="从Google搜索内容" /><Buttonandroid:id="@+id/button2"android:layout_width="wrap_content"android:layout_height="wrap_content"android:layout_alignLeft="@+id/button1"android:layout_below="@+id/button1"android:onClick="IntentTest"android:text="游览网页" /><Buttonandroid:id="@+id/button3"android:layout_width="wrap_content"android:layout_height="wrap_content"android:layout_alignLeft="@+id/button2"android:layout_below="@+id/button2"android:onClick="IntentTest"android:text="显示地图" /><Buttonandroid:id="@+id/button4"android:layout_width="wrap_content"android:layout_height="wrap_content"android:layout_alignLeft="@+id/button3"android:layout_below="@+id/button3"android:onClick="IntentTest"android:text="拨打电话" /><Buttonandroid:id="@+id/button5"android:layout_width="wrap_content"android:layout_height="wrap_content"android:layout_alignLeft="@+id/button4"android:layout_centerVertical="true"android:onClick="IntentTest"android:text="发短信" /><Buttonandroid:id="@+id/button6"android:layout_width="wrap_content"android:layout_height="wrap_content"android:layout_alignLeft="@+id/button5"android:layout_below="@+id/button5"android:onClick="IntentTest"android:text="播放多媒体" /><Buttonandroid:id="@+id/button7"android:layout_width="wrap_content"android:layout_height="wrap_content"android:layout_alignRight="@+id/button4"android:layout_below="@+id/button6"android:onClick="IntentTest"android:text="安装APK" /><Buttonandroid:id="@+id/button8"android:layout_width="wrap_content"android:layout_height="wrap_content"android:layout_alignLeft="@+id/button7"android:layout_below="@+id/button7"android:onClick="IntentTest"android:text="卸载APK" /></RelativeLayout>
