Main point here is onclick listener is implemented on the layout
package com.example.weeknamesdisplay;

import android.view.Menu;
import android.widget.ListView;
public class MainActivity extends Activity {
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
String[] sports = getResources().getStringArray(R.array.sports_array);
final ListView lv1 = (ListView) findViewById(R.id.listV_main);
lv1.setAdapter(new ItemListBaseAdapter(this, sports));
}
}
