I had tried it, but when I want to use a "selector" for my button, it seems the dither can't work again.
res/drawable/keyboard_speeddial_normal_dithered.xml: <nine-patch xmlns:android="http://schemas.android.com/apk/res/android"; android:src="@drawable/keydialer_normal" android:dither="true" /> res/drawable/keyboard_speeddial.xml: <selector xmlns:android="http://schemas.android.com/apk/res/android";> <item android:state_pressed="true" android:drawable="@drawable/keyboard_speeddial_press" /> <item android:state_focused="true" android:drawable="@drawable/keyboard_speeddial_focus" /> <item android:drawable="@drawable/ keyboard_speeddial_normal_dithered" /> </selector> I set the "keyboard_speeddial" as the background of a RelativeLayout. By the way, if I wrap the keyboard_speeddial into another dither xml file such like: res/drawable/keyboard_speeddial_dithered.xml: <nine-patch xmlns:android="http://schemas.android.com/apk/res/android"; android:src="@drawable/keyboard_speeddial" android:dither="true" /> It will cause a runtime exception.
