Android Studio：可绘制xml预览不起作用

Question

Last time I did this, it worked. But now, my Android Studio couldn't show a preview of the drawable which i made before.

Answer 1

See the upper Image click on Version 24 and select Version 23 or below it will solve your problem.

Answer 2

This is only drawable when item is pressed

So remove state_pressed=true

or add not state item

<item>
...
</item>

Answer 3

Android Studio is not showing preview when state_pressed=true . Replace true to false to enable the "show preview".
