How to Implement Tooltip in Android Studio?
A tooltip is a message which appears when a cursor is positioned over an icon, image, hyperlink, or any other GUI component. In this application, we will be using an EditText to take the message from the user and then display that message as a tooltip over a view. Here is a sample video of the application which we are going to build. Note that we are going to implement this project in Java Language.
