How can I set the onItemClick method to show the Text that I clicked in a ListView?

Question

just start my learning in Android. This is a small question but I really want to know how to solve it.

public class MainActivity extends AppCompatActivity {
    ListView l;
    String [] days = {"Sunday", "Monday", "Tuesday", "Wednesday", "Thursday", "Friday", "Saturday"};

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        l = (ListView) findViewById(R.id.ListView);
        ArrayAdapter<String> adapter = new ArrayAdapter<String>(this, R.layout.single_row, R.id.textView, days);
        l.setAdapter(adapter);
        l.setOnItemClickListener(new AdapterView.OnItemClickListener() {
            @Override
            public void onItemClick(AdapterView<?> parent, View view, int position, long id) {

                Toast.makeText(MainActivity.this, "Hi",Toast.LENGTH_SHORT).show();
            }
        });
    }
}

Hope someone can help me. Thank you!

Use the data in days array. position argument of onItemClick method points to which item position you clicked in the ListView.

@Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
    String selected = days[position];
    Toast.makeText(MainActivity.this, selected, Toast.LENGTH_SHORT).show();
}

Thank you so much! By the way, what if I also want to get the index of the text I just clicked? I tried to change `days[position]` to `days[id]` but it is not working. – CHAORAN LI Jan 11 '17 at 19:04
The `position` itself is the index. – K Neeraj Lal Jan 11 '17 at 19:12
Hi, what should I do to make the text and the index of that text to show up in the Toast message? Thank you! – CHAORAN LI Jan 11 '17 at 19:50
`postion + " " + selected` – K Neeraj Lal Jan 12 '17 at 04:48

String selectedFromList =(String) (l.getItemAtPosition(position));

Edit: Neeraj's code is probably the better solution
