Android get thing clicked in listview to setText

Question

I have two classes, a listview class with many strings and a class with a text view .. I want when I click on a string on the listview the second class starts and the textView in it is setText to the item clicked ..

I tried:

      @Override
      protected void onListItemClick(android.widget.ListView l, View v, int position, long id) 
      {
          super.onListItemClick(l, v, position, id);
          String item = (String) getListAdapter().getItem(position);
          Intent select = new Intent(LV.this, Main.class);
          startActivity(select);
      }

and on the second class its

S.setText(LV.item); 

S is the textview

now it appears null ..

Answer 1

You dont get data in one method of an activity in another activity, unless you pass the data between activites. They are only locally available to one activities

Use putExtra to send data from one activity to another. Now in the second activity recieve that value and set it as text to the TextView

Here for e.g

In the first Activity

Intent select = new Intent(LV.this, Main.class);
select.putExtra("item", item)
startActivity(select);

In the next activity, receive this

Bundle extras = getIntent().getExtras();
if (extras != null) {
    String value = extras.getString("item");
}

S.setText(value);
