Soft Keyboard does not persist on focus change from AutoCompleteTextView to EditText

Question

On pressing the next button on the soft keyboard on my AutoCompleteTextView (whether data is entered or not), I have attempted to change focus to the next EditText and keep the soft keyboard. Focus changes, but the soft keyboard goes away. I've attempted to use an InputMethodManager to no avail. Is there something fundamentally incorrect about what I'm doing?

If you want the soft keyboard to show up, then do this

driverAutoCompleteTextView.setOnKeyListener(new View.OnKeyListener() {

    public boolean onKey(View v, int keyCode, KeyEvent event) {
        // If the event is a key-down event on the "enter" button
        if ((event.getAction() == KeyEvent.ACTION_DOWN) &&
                (keyCode == KeyEvent.KEYCODE_ENTER))
        {
            // remove focus from driverAutoCompleteTextView
            driverAutoCompleteTextView.clearFocus();
            // give focus to trailerEditText
            trailerEditText.setFocusable(true);
            trailerEditText.setFocusableInTouchMode(true);
            boolean isFocused = trailerEditText.requestFocus();
            Log.d("myTag","isFocused is: "+isFocused);
            Log.d("myTag","driver auto complete text view focused: "+driverAutoCompleteTextView.isFocused());
            showKeyboard(trailerEditText);

            return true;
        }
        return false;
    }
}); 

private void showKeyboard(View view){
    InputMethodManager manager = (InputMethodManager) this.getSystemService(Activity.INPUT_METHOD_SERVICE);

    manager.showSoftInput(view,InputMethodManager.SHOW_IMPLICIT);
}

This is quick and dirty but it should work. Also, you should add trailerEditText.setFocusableInTouchMode(true) in your onCreate method or in your xml.
