This is all my code given. I added all tags like android:focusable="false", android:focusableInTouchMode="false" in row of list view and also I added android:descendantFocusability="blocksDescendants" in root layout of listview and listView.setItemsCanFocus(false); in code before the listView.setOnItemClickListener but after this onitem click listener does not work and no response.
if you your all code is correct and also no Exception is remain in your code But your ListView On ItemClickListener is not working then you need to use
Restart/invalidate caches option available in Android studio then Run the Listview Project then OnItemClick Listener work correctly.
Click on the File Option on top left corner of the android studio the select the invalidate caches/restart option .
