Android ImageView is raising OnClick event when is hidden
I have couple questions about android views. I'm newbie so if my question seems ridiculous please give me right hint :) So I'm trying to make memory game. Here is my code of mainLayout.
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout

}
}
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.activity_main, menu);
return true;
}
}
Ok so, in first step after create Activiti I'm setting up OnClickListener to every card (pic_a1, pic_a2 ... pic_e5) and visiblity of ImageView paPreviewView to invisible (where i wanna show image of selected card). And then when i clicked to pic_a1 is paPreviewView showed. This is ok. My questions are.
1) In my early version of this example I hid paPreviewView ImageView by calling
paPreviewView.setVisibility(View.INVISIBLE);
or
paPreviewView.setVisibility(View.GONE);
but it didn't work properly. Because method OnClickListener.onClick was called only from hidden paPreviewView ImageView. So i tried to remove OnClickListener from paPreviewView but it didn't help. Only working solution is remove (for hidding ) and add (for showing) paPreviewView from /to mainPanel.
My question is why? Why is paPreviewView raising onClick event when paPreviewView is hidden?
2) And my second question is. Is better solution than I made for this example (I mean card game) ?
Thanks a lot for any idea :)

ImageView.setVisibility() only changes the "visibility" of the view and it still has the listener registered.
You can use:
paPreviewView.setEnabled(false);
to not receive the click events.

The correct function to use in this case would be:
paPreviewView.setClickable(false);
