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...
