This snippet is pretty mutch as the title says, an example in detecting when ScrollView has reached the bottom. In this sample I extend ScrollView and then overrides the onScrollChanged method (inherited from View).
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);
Cheers to this thread for helping me getting the calculations right. Update: You can find a full implementation here:
