xml background don't change when i use tablet

I have an xml that declare the button background:

<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:state_pressed="true" android:drawable="@color/selector_pressed" />
    <item android:state_focused="true" android:drawable="@color/selector_focused" />
    <item android:drawable="@android:color/transparent" />
</selector>

On my phone Samsung Nexus S (android 4.0.3) , this xml work perfectly, when i press the view the background color change. But I got a problem on tablets (Samsung Galaxy tab, Android 3.2), the button is clicked but i don't see any changes for the backgroung. The background color never change for tablets.

Any one have an idea why this happening only for tablets? and how can i fix this?

Solution

  • I've had the same problem but I've managed to solve this: the actual problem lies in a defect in android 3.2 regarding hardware acceleration so if you put in your AndroidManifest that your application is hardwareAccelerated="true" your problem will be solved.
