If you check http://developer.android.com/reference/android/widget/ArrayAdapter.html#ArrayAdapter(android.content.Context, int, T[]), you will find that the array adapter is expecting that the second parameter is a resource id of a text view not a layout..

initialize your adapter using:

new ArrayAdapter(MainActivity.this, android.R.layout.simple_spinner_item, coursesList);
