scroll - Android: Detecting When ScrollView Hits Bottom

Question

(This question already has answers here): question from:https://stackoverflow.com/questions/4953692/android-detecting-when-scrollview-hits-bottom

Answer 1

Try this:

@Override
protected void onScrollChanged(int l, int t, int oldl, int oldt) 
{
    // Grab the last child placed in the ScrollView, we need it to determinate the bottom position.
    View view = (View) getChildAt(getChildCount()-1);

    // Calculate the scrolldiff
    int diff = (view.getBottom()-(getHeight()+getScrollY()));

    // if diff is zero, then the bottom has been reached
    if( diff == 0 )
    {
        // notify that we have reached the bottom
        Log.d(ScrollTest.LOG_TAG, "MyScrollView: Bottom has been reached" );
    }

    super.onScrollChanged(l, t, oldl, oldt);
}

To implement this, extend ScrollView and then override the onScrollChanged method (inherited from View).
