How to select any item from AutoCompleteTextView programmatically in Android Studio?

Question

AutoCompleteTextView autoCompleteTextView
ArrayAdapter<String> adapter;
ArrayList<String> list = new ArrayList<>();

@Override
protected void onCreate(Bundle savedInstanceState) {
    // code...
    list.add("First");
    list.add("Second");
    list.add("Third");
    list.add("Forth");
    list.add("Fifth");
    autoCompleteTextView = findViewById(R.id.auto_complete);
    adapter = new ArrayAdapter<>(this, R.layout.drop_down, list);
    autoCompleteTextView.setAdapter(adpater);
}

then, after adding some strings to ArrayList and linking that list with autoCompleteTextView using Adapter.

autoCompleteTextView.setSelection(3);

Now I want any of my item getting selected automatically, once I open this activity. I treid setSelection() method, but it is not working.

Answer 1

your selected value will store selectedItem

@Override
protected void onCreate(Bundle savedInstanceState) {
    // code...
    autoCompleteTextView = findViewById(R.id.auto_complete);
   
    list.add("First");
    list.add("Second");
    list.add("Third");
    list.add("Forth");
    list.add("Fifth");
 adapter = new ArrayAdapter<>(this, R.layout.drop_down, list);
    autoCompleteTextView.setAdapter(adpater);
autoCompleteTextView.setThreshold(1);
  String selectedItem = autoCompleteTextView.getText().toString();
}
