try this:

@Override
protected void onScrollChanged(int l, int t, int oldl, int oldt) {
        View view = (View) getChildAt(getChildCount()-1);
        int diff = (view.getBottom()-(getHeight()+getScrollY()));// Calculate the scrolldiff
        if( diff == 0 ){  // if diff is zero, then the bottom has been reached
            Log.d(ScrollTest.LOG_TAG, "MyScrollView: Bottom has been reached" );
            yourButton.setVisible(true);
        }
        super.onScrollChanged(l, t, oldl, oldt);
}

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