| public boolean | isActive()Returns true if the drawable is a StateListDrawable and is in the focused state.

| public boolean | isEnabled()Returns true if this target is enabled. Typically an enabled target contains a valid
drawable in a valid state. Currently all targets with valid drawables are valid.
return mDrawable != null && mEnabled;

| private void | resizeDrawables()Makes drawables in a StateListDrawable all the same dimensions.
If not a StateListDrawable, then justs sets the bounds to the intrinsic size of the
drawable.

// Note we explicitly don't set mResourceId to resId since we allow the drawable to be
