<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" > <Button android:id="@+id/button1" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_alignParentTop="true" android:layout_centerHorizontal="true" android:layout_marginTop="184dp" android:background="@drawable/button_selector" /> </RelativeLayout>
android:background="@drawable/button_selector"
(2)在res文件夹下创建drawable文件夹,创建一个selector文件
<?xml version="1.0" encoding="utf-8"?> <selector xmlns:android="http://schemas.android.com/apk/res/android"> <item android:drawable="@drawable/q" android:state_pressed="true"></item> <item android:drawable="@drawable/w" android:state_focused="true"></item> <item android:drawable="@drawable/e"></item> </selector>
文件夹内放三张图片用于切换的时候改变图片
(3)其他内容不需要改变
文件的图片随着按钮的点击变化
