Hello,
I have one question. How can i fill GridView with data from String
array? My code for adapter is :
ArrayAdapter<String> adapter2 = new ArrayAdapter<String>(this,
android.R.layout.simple_list_item_1, tmpx);
gridview.setAdapter(adapter2);
where tmpx is array with strings.
But my app crashes, when i want to run activity.
LogCat error log:
