drawingView &＃61; (DrawingView) rootView.findViewById(R.id.drawingView);

drawingView.setUndoRedoStateDelegate(new DrawingView.UndoRedoStateDelegate() {

&＃64;Override

public void onUndoRedoStateChange(DrawingView drawingView, boolean canUndo, boolean canRedo) {

undoButton.setEnabled(canUndo);

redoButton.setEnabled(canRedo);
