Scrolling of listView under a Scroll View is not happening

Question

Hey I am using Listview under a scroll view. I want to scroll the ListView upto a position dynamically, am trying to do it with the following code but its not scrolling. can anybody please give me a solution.

listView.setSmoothScrollbarEnabled(true); listView.smoothScrollToPosition(position);

Don't use listivew inside scrollview. ListView can scroll on it's own. — Aniruddha, Jun 06 '14 at 11:09

Does the list View scroll otherwise, at run time, when you scroll it using your figure? — Parth Kapoor, Jun 06 '14 at 12:12
no when i add a new item it should be automatically scrolled to that position — Shruti, Jun 06 '14 at 12:35

Instead of using the ScrollToPosition try using the setSelection method of the listView

example:

listView.setSelection(position);

you should be use only listview and remove scrollview from its parent view and put above item of list view as header of listview and same below of listview set as footer of list view.

I can not change my scenrio right now. so please help me with the existed one – Shruti Jun 06 '14 at 11:21
so you have to give a fixed (hard coded) height for list view params. – Pratyesh Jun 06 '14 at 11:28
Yes i have given that, but my problem is m not able to scroll the list dynamically – Shruti Jun 06 '14 at 11:36
because android confuse for take action on move of Scrollview or LstView ,so listview can't scroll as you want. – Pratyesh Jun 06 '14 at 11:57

You can do this just use this class

package com.whathappened.utils;

import android.util.Log;
import android.view.View;
import android.view.ViewGroup;
import android.widget.ListAdapter;
import android.widget.ListView;

public class Helper {
//  public static void getListViewSize(DragSortListView myListView) {
//      
//      ListAdapter myListAdapter = myListView.getAdapter();
//      if (myListAdapter == null) {
//          //do nothing return null
//          return;
//      }
//      //set listAdapter in loop for getting final size
//      int totalHeight = 0;
//      for (int size = 0; size < myListAdapter.getCount(); size++) {
//          View listItem = myListAdapter.getView(size, null, myListView);
//          if(listItem!=null){
//          listItem.measure(0, 0);
//          totalHeight += listItem.getMeasuredHeight();
//          }else{
//              
//          }
//      }
//      //setting listview item in adapter
//      ViewGroup.LayoutParams params = myListView.getLayoutParams();
//      params.height = totalHeight + (myListView.getDividerHeight() * (myListAdapter.getCount() - 1));
//      myListView.setLayoutParams(params);
//      // print height of adapter on log
//      Log.i("height of listItem:", String.valueOf(totalHeight));
//  }



    public static void getListViewSizeGroup(ListView myListView) {
        ListAdapter myListAdapter = myListView.getAdapter();
        if (myListAdapter == null) {
            //do nothing return null
            return;
        }
        //set listAdapter in loop for getting final size
        int totalHeight = 0;
        for (int size = 0; size < myListAdapter.getCount(); size++) {
            View listItem = myListAdapter.getView(size, null, myListView);
            if(listItem!=null){
            listItem.measure(0, 0);
            totalHeight += listItem.getMeasuredHeight();
            }else{

            }
        }
        //setting listview item in adapter
        ViewGroup.LayoutParams params = myListView.getLayoutParams();
        params.height = totalHeight + (myListView.getDividerHeight() * (myListAdapter.getCount() - 1));
        myListView.setLayoutParams(params);
        // print height of adapter on log
        Log.i("height of listItem:", String.valueOf(totalHeight));
    }
}


After setting the adapter just call Helper.getListViewSizeGroup(yourlistviewobject);
it will scroll..
