I have the below XML in slider_button.xml:
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:state_focused="true"
android:state_pressed="false"
android:drawable="@android:drawable/button9patch" />
...
</selector>
The android:drawable="@android:drawable/button9patch" gets the error:
Error: No resource found that matches the given name (at ‘drawable’
with value ‘@android:drawable/button9patch’).
However I think I have the file in the right place (I’ve even put it in all the drawable folders to be sure):

What am I doing wrong? Thanks
change like this
