To add click listener to listview follow these steps

1.add click listener like this in oncreate method of the activity.

listView.setOnItemClickListener(this);

2.Implement OnItemClickListener in the activity.

public class Main2Activity extends AppCompatActivity implements AdapterView.OnItemClickListener {

3.Override the onItemClick method in the activity.

@Override
public void onItemClick(AdapterView<?> adapterView, View view, int i, long l) {
    //Call method here
}
