Hi, You can use the mergeDrawableStates() method of the View class to provide your custom states:
http://code.google.com/android/reference/android/view/View.html#mergeDrawableStates(int[],%20int[]) Try the steps below to create new custom states: 1) Define the state resources in res/values/attrs.xml <declare-styleable name="MyCustomState"> <attr name="state_fried" format="boolean" /> <attr name="state_baked" format="boolean" /> </declare-styleable> 2) In your custom view class : A) Declare the state variables: private static final int[] FRIED_STATE_SET = { R.attr.state_fried }; private static final int[] BAKED_STATE_SET = { R.attr.state_baked }; B) Override the onCreateDrawableState() method: @Override protected int[] onCreateDrawableState(int extraSpace) { final int[] drawableState = super.onCreateDrawableState(extraSpace + 2); if (isFried()) { mergeDrawableStates(drawableState, FRIED_STATE_SET); } if (isBaked()) { mergeDrawableStates(drawableState, BAKED_STATE_SET); } return drawableState; } Once this is done, you should be able to use these in ColorStateListDrawable, but you should use your app's namespace to use these new states: <selector xmlns:android="http://schemas.android.com/apk/res/android"; xmlns:app="http://schemas.android.com/apk/res/<my_app_package>"> <item android:drawable="@drawable/item_baked" state_baked="true" state_fried="false" /> <item android:drawable="@drawable/item_fried" state_baked="false" state_fried="true" /> <item android:drawable="@drawable/item_overcooked" state_baked="true" state_fried="true" /> <item android:drawable="@drawable/item_raw" state_baked="false" state_fried="false" /> </selector> On Mon, Mar 31, 2008 at 9:48 AM, Ted Hopp <[EMAIL PROTECTED]> wrote: > > With some searching I've found several examples and explanations of > customizing the look of a component based on the drawing states.
