Use OnItemClickListener     ListView lv   getListView       lv setOnItemClickListener new OnItemClickListener               Override       public void onItemClick AdapterView lt   gt  adapter  View v  int position              long arg3                       String value    String adapter getItemAtPosition position                   assuming string and if you want to get the value on click of list item                do what you intend to do on click of listview row                  When you click on a row a listener is fired  So you setOnClickListener on the listview and use the annonymous inner class OnItemClickListener   You also override onItemClick  The first param is a adapter  Second param is the view  third param is the position   index of listview items    Using the position you get the item    Edit   From your comments i assume you need to set the adapter o listview  So assuming your activity extends ListActivtiy       setListAdapter adapter      Or if your activity class extends Activity       ListView lv    ListView  findViewById R id listview1          initialize adapter       lv setAdapter adapter
