I have group indication with small icon, and i use groupIndicator to call the selector to draw it but I see android by default stretch that icon to fits the text size
how can i prevent that behavior, and display the icon with it’s original size ?
You can add group indicator by setGroupIndicator method. But By default, Android stretch height of indicator to fit group item’s height. (width can be adjusted by setIndicatorBounds method.)
Therefore, you should make group indicator’s height exactly same as group item’s height.
(see ExpandableListView)
Otherwise, you can make fully customized group indicator with onGroupCollapsed and onGroupExpanded methods. Just make a view with some states and When these methods are called, change your view’s state. (see ExpandableListAdapter)
