مشکل nullpointerexceptionدر کد آداپتر (حل شده)

به نظر شما چرا از خط مشخص شده شده ارور null میگیره؟

 

public class MyAdapter extends ArrayAdapter<Item> implements PinnedSectionListAdapter {

    private static final int[]    COLORS       = new int[]{ R.color.blue_light };

            section.sectionPosition = sectionPosition;
            section.listPosition = listPosition++;
            onSectionAdded(section, sectionPosition);

        }
    }

        if (text != null) {

            rate.setRating(2.5f); این خط ارور داره

        }
