I set onitemclicklistener for my AutoCompleteTextView and in it I manually do setText for the AutoCompleteTextView:

    editNumber = (AutoCompleteTextView) findViewById(R.id.editNumber);
    NumberAdapter adapter = new NumberAdapter(
            this, 
            ContactInfo.getContacts(this.getContentResolver()));
    editNumber.setAdapter(adapter);

    editNumber.setOnItemClickListener(this);
    ....

public void onItemClick(AdapterView<?> parent, View view, int position,
        long id) {
    ContactInfo ci = (ContactInfo)parent.getItemAtPosition(position);
    editNumber.setText(ci.Number);
}
