In the main Acticity use this Utility class to change the listview height.
phraseListView=(ListView)findViewById(R.id.phrase_listview);
phraseAdapter=new PhraseListAdapter(this);
phraseListView.setAdapter(phraseAdapter);
setListViewHeightBasedOnChildren(phraseListView);
2) If Adapter item's height is dynamic then use this function before nofitydataSetChanged()
public static void setListViewHeightBasedOnChildren(ListView listView) {
ListAdapter listAdapter = listView.getAdapter();
if (listAdapter == null) {
return;
}
int totalHeight = 0;
int desiredWidth = View.MeasureSpec.makeMeasureSpec(listView.getWidth(), View.MeasureSpec.UNSPECIFIED);
for (int i = 0; i < listAdapter.getCount(); i++) {
View listItem = listAdapter.getView(i, null, listView);
listItem.measure(desiredWidth, View.MeasureSpec.UNSPECIFIED);
totalHeight += listItem.getMeasuredHeight();
}
ViewGroup.LayoutParams params = listView.getLayoutParams();
params.height = totalHeight + (listView.getDividerHeight() * (listAdapter.getCount() - 1)) + 10;
Log.e("HEIGHT","HEIGHT::::::"+params.height);
listView.setLayoutParams(params);
listView.requestLayout();
