Question

I am using autocompletetextview in my app and putting 4 items in my strings.xml file. When I type a letter, the dropdowm list is populated according to the letter I type. What I need it to do, however, is whenever I type a letter all the values from strings.xml must be shown in the dropdown list on autocompletetextview. Is this possible?

You have to subclass AutoCompleteTextView so it does not send the text inside the EditText to the filter:

public class MyAutoCompleteTextView extends AutoCompleteTextView {

    public MyAutoCompleteTextView(Context context) {
        super(context);
    }

    public MyAutoCompleteTextView(Context context, AttributeSet attrs) {
        super(context, attrs);
    }

    public MyAutoCompleteTextView(Context context, AttributeSet attrs, int defStyle) {
        super(context, attrs, defStyle);
    }

    // Allows you to show options on empty string.
    public boolean enoughToFilter() {
        return true;
    }
    // Override to always send an empty string.
    @Override
    protected void performFiltering(CharSequence text, int keyCode) {
        super.performFiltering("", 0);
    }
}
