How to detect the user hovering over a view?

22 min read

To detect when a user is hovering over a view, you can use the following steps:

  1. Implement a OnHoverListener on the view you want to track the hovering action. For example, if you have a Button called myButton, you would set the listener like this:
myButton.setOnHoverListener(new View.OnHoverListener() {
     @Override
     public boolean onHover(View v, MotionEvent event) {
         // Handle hover events here
         if (event.getAction() == MotionEvent.ACTION_HOVER_ENTER) {
             // User started hovering over the view
             return true;
         } else if (event.getAction() == MotionEvent.ACTION_HOVER_EXIT) {
             // User stopped hovering over the view
             return true;
         }
         return false;
     }
});

  1. Inside the onHover() method, you can check the MotionEvent action to determine if the user started (ACTION_HOVER_ENTER) or stopped (ACTION_HOVER_EXIT) hovering over the view.

  2. Perform your desired actions when the user starts or stops hovering over the view. In the example above, a true return value is used to indicate that the event has been consumed and no further processing is required. You can return false if you want the event to be passed on to other listeners.

By implementing the OnHoverListener and monitoring the MotionEvent actions, you can detect when a user is hovering over a specific view.
