saurabhdtu commented 7 years ago

I am using a custom layout. I tried using frame layout and linear layout as the root view also tried match_parent and some constant number with the width and height.. for the root view. but the crash still occurs

java.lang.NullPointerException: Attempt to read from field 'int android.view.ViewGroup$MarginLayoutParams.leftMargin' on a null object reference at com.lorentzos.flingswipe.SwipeFlingAdapterView.makeAndAddView(SwipeFlingAdapterView.java:149) at com.lorentzos.flingswipe.SwipeFlingAdapterView.layoutChildren(SwipeFlingAdapterView.java:132) at com.lorentzos.flingswipe.SwipeFlingAdapterView.onLayout(SwipeFlingAdapterView.java:117)

Figured it out. It was due to a silly bug that i had in the array adapter on bindview method.

Could you elaborate on the bug? I have the same error.

        //Earlier I was using this code. Later replaced it with the code below : itemView = layoutInflater.inflate(R.layout.item_group_match_request, null);
            itemView = layoutInflater.inflate(R.layout.item_group_match_request, parent, false);
