I have a customer adapter which is used to displays a list of items. I want to show a light white colored tint over the whole custom adapter whenever the user long clicks an item to give a sense of selection (I also plan to place an image over it later on, like a heart or thumbs icon to represent that the item has been liked but that's a different story).
But the problem is how to do it, I can't figure it out and also couldn't find anything on Google.
What would be a simple way for doing it?
Why you aren't trying to change the value of alpha of your adapterview? Just like-
public View getView(final int position, View convertView, ViewGroup parent)
{ .
.
.
convertView.setAlpha(0.4); //change the value as per your need
}
Even if you don't want to use this feel free to make a state_selected item in your selector and use on your adapter onItemLongClick.
