给RelativeLayout设置背景，无效果bug解决

drawable文件夹下面 tomyshop_selector.xml文件

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

    <item android:state_focused="true"
        android:drawable="@color/color_E2590E"/>
    <item android:state_pressed="true"
        android:drawable="@color/color_E2590E"/>
    <item android:drawable="@color/color_FF5F07"/>

</selector>

布局里面:一定要加上android:clickable="true"否则没有效果

 <RelativeLayout
                    android:layout_width="match_parent"
                    android:layout_height="match_parent"
                    android:background="@drawable/tomyshop_selector"
                    android:clickable="true"
                    android:layout_weight="1">
