android studio的报错提示：

AAPT: error: '#DCDCDC' is incompatible with attribute drawable (attr) reference.

解决，打开selector_view_name_state.xml看看内容：

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:drawable="#DCDCDC" android:state_pressed="true"/>
    <item android:drawable="@color/cf2f2f2" android:state_pressed="false"/>
</selector>

错误译文是：drawable="#DCDCDC"，改为drawable="@color/cdcdcdc"，通过定义引入就兼容了

还是在color.xml里指定一下颜色，通过定义引入就兼容了

<?xml version="1.0" encoding="utf-8"?>
<resources>
    <!--  自定义的颜色  -->
    <color name="cdcdcdc">#DCDCDC</color>
</resources>
