Android: id list view

Question

I have a list view declared in my xml:

Answer 1

Your ListView object id should be specified either as android:id="@android:id/list"

ListView lv = (ListView) findViewById(android.R.id.list);

or it should have some other id like android:id="@+id/sampleList"

ListView lv = (ListView) findViewById(R.id.sampleList);

Check this : ListActivity

and list

Hope this would help.
