Android--利用selector设置Button

如下图所示，为了实现这个效果：

主要有两部分：

• 按键
• 文字

按键

android:background="@drawable/button_selector"

button_selector.xml

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

    <item android:drawable="@drawable/btn_pressed" android:state_pressed="true"/> 

selector>

btn_pressed.xml

<shape xmlns:android="http://schemas.android.com/apk/res/android">
    <solid android:color="#020c41">solid> 
    <stroke android:width="1dp" android:color="#FFFFFF">stroke> 
shape>

<shape xmlns:android="http://schemas.android.com/apk/res/android">

文字

android:textColor="@drawable/text_color_selector"
