     ScrollView

         RelativeLayout

             LinearLayout

             

        

Answer 1

import android.view.ViewGroup.LayoutParams;

 ListView mListView = (ListView)   findViewById(R.id.listviewid);
 LayoutParams list = (LayoutParams) mListView.getLayoutParams();
   list.height = set the height acc to you;//like int  200
   mListView.setLayoutParams(list);

Answer 2

this class can be use to expand the height of listview or gridview at runtime ,please put it in your package and use by passing listview

public class CustomView {

        public static void getListViewSize(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);
                listItem.measure(0, 0);
                totalHeight += listItem.getMeasuredHeight();
            }
            //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 getGridViewSize(GridView myGridView) {
            ListAdapter myListAdapter = myGridView.getAdapter();
            if (myListAdapter == null) {
                //do nothing return null
                return;
            }
            //set listAdapter in loop for getting final size
            int totalHeight = 0;
            int maxHeight = 0;//implement new 
            for (int size = 0; size < myListAdapter.getCount(); size++) {
                View listItem = myListAdapter.getView(size, null, myGridView);

                listItem.measure(0, 0);

                totalHeight += listItem.getMeasuredHeight()+8;

                if(maxHeight < listItem.getMeasuredHeight()){//implement new 

                    maxHeight = listItem.getMeasuredHeight()+8;
                    System.out.println(" max height of gridview item<11>  "+size+"  ==  "+maxHeight);
                }

                System.out.println(myListAdapter.getCount()+"  height of gridview item<22>  "+size+"  ==  "+listItem.getMeasuredHeight());
            }

            //setting listview item in adapter
             ViewGroup.LayoutParams params = myGridView.getLayoutParams();

            if(myListAdapter.getCount() > 1)
                params.height = maxHeight * ((myListAdapter.getCount()+1)/2);//implement new
            else
                params.height = maxHeight;//implement new

             myGridView.setLayoutParams(params);

        }


    }

Try this answer,

public static void setListViewHeightBasedOnChildren(final ListView listView) {
    listView.post(new Runnable() {
        @Override
        public void run() {
            ListAdapter listAdapter = listView.getAdapter();
            if (listAdapter == null) {
                return;
            }
            int totalHeight = listView.getPaddingTop() + listView.getPaddingBottom();
            int listWidth = listView.getMeasuredWidth();
            for (int i = 0; i < listAdapter.getCount(); i++) {
                View listItem = listAdapter.getView(i, null, listView);
                listItem.measure(
                        View.MeasureSpec.makeMeasureSpec(listWidth, View.MeasureSpec.EXACTLY),
                        View.MeasureSpec.makeMeasureSpec(0, View.MeasureSpec.UNSPECIFIED));


                totalHeight += listItem.getMeasuredHeight();
                Log.d("listItemHeight" + listItem.getMeasuredHeight(), "___________");
            }
            ViewGroup.LayoutParams params = listView.getLayoutParams();
            params.height = (int) ((totalHeight + (listView.getDividerHeight() * (listAdapter.getCount() - 1))));
            listView.setLayoutParams(params);
            listView.requestLayout();

        }
    });
   }

Answer 4

 <ScrollView
        android:layout_width="match_parent"
        android:layout_height="match_parent">

<LinearLayout
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:layout_weight="1">
            <ListView
                android:id="@+id/lv_premimum_upgrade"
                android:layout_width="match_parent"
                android:layout_height="wrap_content"
                android:layout_marginTop="@dimen/custom_margin"
                android:minHeight="48dp">
            </ListView>
        </LinearLayout> 

</ScrollView>

int list_cell_size=188;    // cell_size is varible 
ViewGroup.LayoutParams list;
list = (ViewGroup.LayoutParams) listView.getLayoutParams();
list.height = list_cell_size*response.size();  // response is list items size
listView.setLayoutParams(list);

Answer 5

Its not recommended to use ListView inside of a ScrollView

Answer 6

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();
    }
}
