Why is the forceLayout method called on a View object in Android?

The forceLayout() method on a View object in Android is used to forcibly reset the current layout state and initiate a new measure/layout pass for that view and its descendants.

This is useful when you have changed parameters affecting the size or position of the View and want to immediately update its display without waiting for the next UI update cycle.

Example usage:

view.forceLayout();
view.requestLayout();

However, requestLayout() is more commonly used, and forceLayout() is rarely applied, only in specific cases where you need to reset the flag indicating that the layout is valid to ensure a re-layout pass.
