Android : How to add a listview inside a scrollview.?

Question

In an android application, I have a linear layout with vertical orientation. This layout contains 2 childs(listview and a textview). The problem is the layout has to show the textview only when the listview has finished scrolling. Plz help me to design the layout?

All you need to know is when the listview is at the bottom or showing the last item, then make your textview visible, this code does the trick:

yourListView.setOnScrollListener(this);//The class must implement onscrolllistener

@Override
public void onScroll(AbsListView lw, final int firstVisibleItem,
                 final int visibleItemCount, final int totalItemCount) {

    switch(lw.getId()) {
        case android.R.id.list:     

            // Make your calculation stuff here. You have all your
            // needed info from the parameters of this function.

            // Sample calculation to determine if the last 
            // item is fully visible.
             final int lastItem = firstVisibleItem + visibleItemCount;
           if(lastItem >= totalItemCount) {
              if(preLast!=lastItem){ //to avoid multiple calls for last item
                Log.d("Last", "Last");
                preLast = lastItem;
                //Make your text view visible
              }
           }
    }
}

Is also important to mention that "You Should not have a listview within a ScrollView.", it goes against the Android Design Guidelines and chances are that you are doing something terribly wrong if you go for that approach.

Hope it Helps!

Thanks Martin. Your solution worked for me. I also took your suggestion and changed my implementation of having a listview inside a scrollview. — Umesh Isran, Jul 30 '14 at 09:25
