I have an issue, maybe it's because a missing import.

Question

I want to make spinner in my app that I could select item using it. so my code was:
map_picker.setAdapter(new ArrayAdapter<String>(getBaseContext(),
android.R.layout.simple_spinner_dropdown_item, mapsTit));

that code caused an error message:
The type MainActivity.ArrayAdapter is not generic; it cannot be parameterized with arguments <String>

Then I searched google. And knew that it was because of error in input! My input: no enought space here to write it!
