[From the docs](http://developer.android.com/reference/android/widget/ScrollView.html)"You should never use a ScrollView with a ListView, because ListView takes care of its own vertical scrolling." — codeMagic, Jul 03 '13 at 13:35
add this to your ScrollView tag : android:fillViewport="true" — mmoghrabi, Jul 03 '13 at 13:44

NEVER put a list view inside a scroll view or vice versa! It says so right in the documentation:

You should never use a ScrollView with a ListView, because ListView takes care of its own vertical scrolling. Most importantly, doing this defeats all of the important optimizations in ListView for dealing with large lists, since it effectively forces the ListView to display its entire list of items to fill up the infinite container supplied by ScrollView.

hai just i replace above coding with full code please give solution — Satheesh, Jul 03 '13 at 13:44

Create Class Like this:

public class Utility {

public static void setListViewHeightBasedOnChildren(ListView listView) {
    ListAdapter listAdapter = listView.getAdapter();
    if (listAdapter == null) {
        // pre-condition
        return;
    }

    int totalHeight = 0;
    int desiredWidth = MeasureSpec.makeMeasureSpec(listView.getWidth(), MeasureSpec.AT_MOST);
    for (int i = 0; i < listAdapter.getCount(); i++) {
        View listItem = listAdapter.getView(i, null, listView);
        listItem.measure(desiredWidth, MeasureSpec.UNSPECIFIED);
        totalHeight += listItem.getMeasuredHeight();
    }

    ViewGroup.LayoutParams params = listView.getLayoutParams();
    params.height = totalHeight + (listView.getDividerHeight() * (listAdapter.getCount() - 1));
    listView.setLayoutParams(params);
    listView.requestLayout();
}
}

Call this method at where do you want Scroll your listview like this.

Utility.setListViewHeightBasedOnChildren(YourListView);

For your Reference.

Hope this will help you.

    //requestDisallowInterceptTouchEvent(true);
    // use above method to disable listview scroll and enabled scrollview scroll
    // to disable listview.requestDisallowInterceptTouchEvent(true);
    // to enabled scrollview scroll write as below
    // ex:  ((MainActivity) context).listview.requestDisallowInterceptTouchEvent(true);
    // i  have used above things on viewHolder.l1.setOnTouchListener(new View.OnTouchListener()
