Hi,
I am trying to use that small favorite icon (the Android star icon,
android:drawable/btn_star), which according to its XML definition has
several distinct states in which it looks different (e.g. it's a
golden filled star when checked, and a grey unfilled star when
unchecked).
Whenever the ImageView rendering that drawable receives a click event,
I want to switch those two states. Here is what I do:
starIcon.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
Drawable star = starIcon.getDrawable();
int[] currentState = star.getState();
System.out.println(StateSet.dump(currentState));
if (StateSet.stateSetMatches(currentState,
android.R.attr.state_checked)) {
System.out.println("is checked");
star.setState(new int[]
{ android.R.attr.state_enabled });
} else {
System.out.println("not checked");
star.setState(new int[]
{ android.R.attr.state_checked });
}
star.invalidateSelf();
}
});
however, the onclick handler always enters the else clause and the
dump always prints W P E, which means that the call to setState
(checked) has no effect... I guess?
What am I missing?
Thanks,
Matthias
