Answer 1

If you want to add ListView on ScrollView and adjust the height of ListView try this code

if (adapter != null) {
    int totalHeight = 0;
    for (int i = 0; i < adapter.getCount(); i++) {
         View listItem = adapter.getView(i, null, listView);
         listItem.measure(0, 0);
         totalHeight += listItem.getMeasuredHeight() + (listItem.getMeasuredHeightAndState()/2);
    }
    ViewGroup.LayoutParams params = listView.getLayoutParams();
    params.height = totalHeight + (listView.getDividerHeight() * (adapter.getCount() - 1));
    listView.setLayoutParams(params);
    listView.requestLayout();

This will help you.

 ListAdapter listadp = listview.getAdapter();
       if (listadp != null) {
           int totalHeight = 0;
           for (int i = 0; i < listadp.getCount(); i++) {
               View listItem = listadp.getView(i, null, listview);
               listItem.measure(0, 0);
               totalHeight += listItem.getMeasuredHeight();
           }
           ViewGroup.LayoutParams params = listview.getLayoutParams();
           params.height = totalHeight + (listview.getDividerHeight() * (listadp.getCount() - 1));
           listview.setLayoutParams(params);
           listview.requestLayout();

you can try this function to update the height of listView

public static void updateListViewHeight(ListView myListView) {
    ListAdapter myListAdapter = myListView.getAdapter();
    if (myListAdapter == null) {
        return;
    }
    // get listview height
    int totalHeight = 0;
    int adapterCount = myListAdapter.getCount();
    for (int size = 0; size < adapterCount; size++) {
        View listItem = myListAdapter.getView(size, null, myListView);
        listItem.measure(0, 0);
        totalHeight += listItem.getMeasuredHeight();
    }
    // Change Height of ListView
    ViewGroup.LayoutParams params = myListView.getLayoutParams();
    params.height = (totalHeight
            + (myListView.getDividerHeight() * (adapterCount));
    myListView.setLayoutParams(params);
}
