导读：?xml version="1.0" encoding="utf-8"? selector xmlns:android = "http://schemas.android.com/apk/res/android" item android:state_pressed = "true" shape android:shape = "rectangle" solid android:color = "@color/yellow" / stroke android:color =

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:state_pressed="true">
        <shape android:shape="rectangle">
            <solid android:color="@color/yellow"/>
            <stroke android:color="@color/white" android:width="@dimen/dp1"/>
        </shape>
    </item>
    <item android:state_focused="true">
        <shape android:shape="rectangle">
            <solid android:color="@color/yellow"/>
            <stroke android:color="@color/white" android:width="@dimen/dp1"/>
        </shape>
    </item>
    <item android:state_checked="true">
        <shape android:shape="rectangle">
            <solid android:color="@color/yellow"/>
            <stroke android:color="@color/white" android:width="@dimen/dp1"/>
        </shape>
    </item>



    <item >
        <shape android:shape="rectangle">
            <solid android:color="@color/black"/>
            <stroke android:color="@color/white" android:width="@dimen/dp1"/>
        </shape>
    </item>
</selector>

其实可以将shape单独拎出来，单独出来，其效果反而更好，增加可复用性，降低ctrl+c和ctrl+v，而且只专注于一项事情，此篇幅只是说selector是可行的。

单独拎出来如下：
1、创建shape:
stroke_white_solic_yellow_rec_shape.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/yellow"/>
    <stroke android:color="@color/white" android:width="@dimen/dp1"/>
</shape>

2、设置selector

<item android:state_checked="true" android:drawable="@drawable/stroke_white_solic_yellow_rec_shape" />
