Have you worked with the invalidate() method to update the view display?

The invalidate() method in Android is used to mark a View as needing to be redrawn. When invalidate() is called, the system schedules a call to the onDraw() method for that View in the next drawing cycle, allowing the display to be updated with new data or state changes.

Example usage:

myView.invalidate(); // Request to redraw myView

This is useful when you change internal data of the View, such as color, position, or content, and want these changes to be reflected on the screen. It is important to call invalidate() from the UI thread, otherwise, an error may occur.
