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

Issue

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.

Solution

We need to pass false as second argument to setText() method.

autoCompleteTextView.setText("First", false);

If we don't pass second arguiment "false" as a filter to setText() method, it will clear all the entries inside list and will keep just one entry. that we set as using setText() method.
