Hello,
My following code does an exception when I'm trying to display the
dropdownview. I uses the default standard object ArrayAdapter
displaying string...but there is an issue that I can't resolve. I
tried a lot of thing...So maybe i'm tired or i don't understand
something somewhere!
Thanks for your help
mRegions is an array of String, not null.
mSpinnerRegions is my spinner view.
ArrayAdapter<String> adapterRegion = new ArrayAdapter<String>(this,
android.R.layout.simple_spinner_item, mRegions);
adapterRegion
.setDropDownViewResource
(android.R.layout.simple_spinner_dropdown_item);
mSpinnerRegions.setAdapter(adapterRegion);
Exception
