这是按钮选择器的完整XML代码

button_normal.xml

<?xml version="1.0" encoding="utf-8"?>
<shape  xmlns:android="http://schemas.android.com/apk/res/android" 
       android:shape="rectangle">

       <solid android:color="@color/button_light_green"/>
        <corners android:radius="5dp" />

</shape>

button_selected.xml

<?xml version="1.0" encoding="utf-8"?>
<shape  xmlns:android="http://schemas.android.com/apk/res/android" 
       android:shape="rectangle">

       <solid android:color="@color/button_light_green_selected"/>
        <corners android:radius="5dp" />

</shape>

button_bg.xml

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android" >
    <item android:state_pressed="true" android:drawable="@drawable/button_selected"/>
    <item android:state_focused="true" android:drawable="@drawable/button_selected"/>
    <item android:drawable="@drawable/button_normal"/> 
</selector>

最后将其添加到您的按钮背景中......

<Button
android:layout_marginTop="20dp"
android:id="@+id/button1"
android:layout_width="match_parent"
android:layout_height="150sp"
android:text="add"
android:gravity="center" 
android:layout_centerHorizontal="true"
android:layout_below="@+id/spin"
android:background="@drawable/button_bg"/> <!-- Add Selector File here to have click effect -->
