Java switch statement completely skipped

Question

I am trying a switch statement to dynamically determine which part of an actionbar dropdown spinner is being selected. This switch statement does not even go to my default case, what am I doing wrong?

public boolean onNavigationItemSelected(int itemPosition, long itemId) {
    // TODO Auto-generated method stub

    //restart fragment with selected spinner item's api call
    TypedArray mArray = getResources().obtainTypedArray(R.array.spinner_actionbar);
    switch(mArray.getResourceId(itemPosition, 0)){
    case R.string.spinner_timeline:
        break;
    case R.string.spinner_profile:
        break;
    case R.string.spinner_top_posts:
        break;
    case 0:
        break;
    default:
        break;
    }
    mArray.recycle();
    return false;
}

mArray.getResourceId(itemPosition, 0) returns the position of an arraylist OR 0, and none of my cases not even case 0 is being called

Thanks for any insight, this is using the android framework

You have empty cases in your switch-case block. You want to do something inside each case, besides just break out of the block. For example:

case R.string.spinner_timeline:
    System.out.println(R.string.spinner_timeline);
    break;
case R.string.spinner_profile:
    System.out.println(R.string.spinner_profile);
    break;
case R.string.spinner_top_posts:
    System.out.println(R.string.spinner_top_posts);
    break;
case 0:
    break;
default:
    System.out.println("default case...");
    break;
