Android2D Redraw View
To redraw View class.
We want to update View class to add item or something.
In that case, we should use invalidate method of View class;
Inside of View class
public class DrawView extends View { public DrawView ( Context context ) { super(context); } @Override protected void onDraw ( Canvas canvas ) { } private void update() { invalidate(); // Can call directly. } }
Outside of View class
private View view; public void updateView() { view.invalidate(); }
I tested it in Timer example. here.
