Android: AutoCompleteTextView show suggestions when no text entered

Question

I am using AutoCompleteTextView, when the user clicks on it, I want to show suggestions even if it has no text - but setThreshold(0) works exactly

Answer 1

Destil's code works just great when there is only one InstantAutoComplete object. It didn't work with two though - no idea why. But when I put showDropDown() (just like CommonsWare advised) into onFocusChanged() like this:

@Override
protected void onFocusChanged(boolean focused, int direction,
        Rect previouslyFocusedRect) {
    super.onFocusChanged(focused, direction, previouslyFocusedRect);
    if (focused) {
        performFiltering(getText(), 0);
        showDropDown();
    }
}

it solved the problem.

It is just the two answers properly combined, but I hope it may save somebody some time.
