AutoCompleteTextView item selection programmatically

Question

I have an autocomplete text view that is filled with cities from an sqlite database that calls an async task on item click, recently I added an option to detect my location usin

Answer 1

I have used autoCompleteTextView.setText(myText, false); solution as well, however it sometimes failed. I mean it was actively filtering results so, when user clicks there was only 1 item at dropdown.

In addition I also needed this to work on custom objects as well, and this is my my solution:

binding.hourEditText.configureDropDownMenu(viewModel.hours) { it.hourString() }
    .subscribe {
        // Do whatever you need when on click.
    }
    .addTo(disposables)

fun  AutoCompleteTextView.configureDropDownMenu(list: List, toString: ((T) -> String)? = null): Observable {
    keyListener = null
    val textItems = toString?.let(list::map) ?: list.map { it.toString() }
    setAdapter(NonFilterArrayAdapter(context!!, android.R.layout.simple_spinner_dropdown_item, textItems))
    return itemClickEvents().map {
        list[it.position]
    }
}

private class NonFilterArrayAdapter(context: Context, @LayoutRes resource: Int, objects: List) : ArrayAdapter(context, resource, objects) {

    override fun getFilter() = NonFilter()

    private class NonFilter : Filter() {
        override fun performFiltering(constraint: CharSequence?) = FilterResults()

        override fun publishResults(constraint: CharSequence?, results: FilterResults?) = Unit
    }
}

Note: This also contains a bit of Rx, but it can be removed easily.
