Toolbar setOnScrollChangeListener() for api level 19

Question

Is there any alternate listener which I can use to get scrolling amount in y axis?

I am using android.support.v7.widget.Toolbar but it doesn't have backward compatibility to API level 19.

Answer 1

You can achieve that using ViewTreeObserver#addOnScrollChangedListener() API:

    toolbar.getViewTreeObserver().addOnScrollChangedListener(
        new ViewTreeObserver.OnScrollChangedListener() {
          @Override public void onScrollChanged() {
              int x = toolbar.getScrollX();
              int y = toolbar.getScrollY();
          }
        });

Answer 2

If i have understood properly , you can use addOnScrollChangedListener() instead.

Hope this helps. Sorry for my english.
