Do not add a ListView to a ScrollView if you don't know exaclty what you are doing.
Do not add a ListView to a ScrollView also if you are the best android programmer in the World.
ListViews are not supposed to get in ScrollView. Even if you hack, and i mean big hack, both views by extending them and got them to scroll , also be itemclickable etc etc , something will break eventually. Also do not add a ListView to a ScrollView.
Watch this
You should first get the ListView in you layout using findViewById(android.R.id.list) then you cant add the items into ListView and then add this to scrollview.
You cannot get reference to the ListView this way. You should execute findViewById(/Id of the listview element goes here/).
Edit:
Suppose you have:
<ListView android:layout_height="wrap_content" android:id="@+id/listView1" android:layout_weight="1" android:layout_width="fill_parent"></ListView>
You can get access to the listview by:
ListView l = findViewById(R.id.listView1);
Hope this helps!
Got the solution....here is the complete the code...
