Answer 2

您需要使用背景自定义Selector（类似于Tabs选择器）到您的Button。

<Button 
    android:id="@+id/button" 
    android:background="@drawable/button_background" 
    android:layout_width="wrap_content" 
    android:layout_height="wrap_content" 
    android:text="My button" /> 

你​​：

<selector xmlns:android="http://schemas.android.com/apk/res/android"> 
    <!-- Non focused states --> 
    <item android:state_focused="false" android:state_selected="false" android:state_pressed="false" android:drawable="@drawable/tab_unselected_holo" /> 
    <item android:state_focused="false" android:state_selected="true" android:state_pressed="false" android:drawable="@drawable/tab_selected_holo" /> 

    <!-- Focused states --> 
    <item android:state_focused="true" android:state_selected="false" android:state_pressed="false" android:drawable="@drawable/tab_unselected_focused_holo" /> 
    <item android:state_focused="true" android:state_selected="true" android:state_pressed="false" android:drawable="@drawable/tab_selected_focused_holo" /> 

    <!-- Pressed --> 
    <!-- Non focused states --> 
    <item android:state_focused="false" android:state_selected="false" android:state_pressed="true" android:drawable="@drawable/tab_unselected_pressed_holo" /> 
    <item android:state_focused="false" android:state_selected="true" android:state_pressed="true" android:drawable="@drawable/tab_selected_pressed_holo" /> 

    <!-- Focused states --> 
    <item android:state_focused="true" android:state_selected="false" android:state_pressed="true" android:drawable="@drawable/tab_unselected_pressed_holo" /> 
    <item android:state_focused="true" android:state_selected="true" android:state_pressed="true" android:drawable="@drawable/tab_selected_pressed_holo" /> 
</selector> 

• tab_unselected_holo
• tab_selected_holo
• tab_unselected_focused_holo
• tab_selected_focused_holo
• tab_unselected_pressed_holo
• tab_selected_pressed_holo
