Android AutoCompleteTextView is very slow

I have a list of 250 thousand lines that I will put in AutoCompleteTextView

.

When I apply them to the view, the suggestion tooltips are displayed for about 10-20 seconds.

Since all values ​​are at least 10 characters long, I also tried setting the threshold to 5, but it didn't seem to help much.

The code I used:

List<String> locations = GetLocations();
ArrayAdapter<String> adapter = new ArrayAdapter<String>(this, android.R.layout.simple_dropdown_item_1line, locations);
((AutoCompleteTextView) findViewById(R.id.txt_location)).setAdapter(adapter);
((AutoCompleteTextView) findViewById(R.id.txt_location)).setThreshold(5);

      

        
        
        
      

    

Is there a way to make this behavior faster, or am I missing another alternative approach for this case?

Edit: Now that I've been looking a little more, there seems to be no choice but to implement my own logic ( How to speed up AutocompleteTextView in Android? )
