I am adding a spinner dynamically in a layout, as;
public class FRQuestionsDetail extends Activity implements OnClickListener,

private int questionId;
private int count = 0;
private int position;

private long questionScore;;

FRReviewQuestionsTable db = new FRReviewQuestionsTable(

But when I click on the spinner, my app crashes and I got the following error.

I do not know, how to select an item in the spinner or how to make a spinner selectable or clickable.
Note: My this activity is one of the activities in my ActivityGroup.
Please help me out in this. Thank You!
Your logcat says
android.view.WindowManager$BadTokenExceptionwhich means you are passing invalid Context somewhere.I doubt this line
Try using
Spinner spin=new Spinner(YourActivity.this)orSpinner spin=new Spinner(getApplicationContext())
