Android. How to add items to ListView from BroadcastReceiver?

public class AddNewRequestActivity extends Activity {
protected void onCreate(Bundle savedInstanceState) {
// create a BroadcastReceiver
 br = new BroadcastReceiver() {
 // actions when receiving messages
 public void onReceive(Context Context, Intent intent) {
String[] names = { "John", "Mary", "Peter", "Anton", "Dora", "Boris",
 "Kostya", "Igor", "Anna", "Denis", "John" };

// find the list
 ListView lvMain = (ListView) findViewById(R. id.listViewRequests);
 // create the adapter
 ArrayAdapter<string> adapter = new ArrayAdapter<string>(AddNewRequestActivity.this, android.R.layout.simple_list_item_1, names);
 // assign adapter to list
lvMain.setAdapter(adapter);

}
};
// create a filter for BroadcastReceiver
 IntentFilter intFilt = new IntentFilter(BROADCAST_ACTION);
 // pending (include) BroadcastReceiver
 registerReceiver(br, intFilt);
}
}</string></string>
