整理下button 按下效果，切换背景：

       在drawable下新建bg_hangup.xml

<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:state_pressed="false" android:drawable="@drawable/haangup" />
<item android:state_focused="true" android:drawable="@drawable/number_press_dial" />
<item android:state_pressed="true" android:drawable="@drawable/number_press_dial" />
</selector>

 使用时直接 在view下添加

android:src="@drawable/haangup" 

 PS：附上拨号自定义盘布局改写

    <item name="android:gravity">center</item>
    <item name="android:background">@color/line_color</item>
    <item name="android:orientation">horizontal</item>
</style>

<style name="layout1_input_amount_style">
