NullPointerException after screen orientation change

[zasadnyy]

I have case when for portrait orientation I have one column and for landscape two columns. If we rotate from portrait to landscape we'll get NullPointerException. Stacktrace:

Here is how I've fixed this issue:

         final int top = getPaddingTop();
         for(int i = 0; i<colCount; i++){
-           final int offset =  top + ((mRestoreOffsets != null)? Math.min(mRestoreOffsets[i], 0) : 0);
+            int offset = top;
+            if((mRestoreOffsets != null) && mRestoreOffsets.length == colCount)
+                offset +=  Math.min(mRestoreOffsets[i], 0);
            mItemTops[i] = (offset == 0) ? mItemTops[i] : offset;
            mItemBottoms[i] = (offset == 0) ? mItemBottoms[i] : offset;
         }
