Android: Custom ListAdapter extending BaseAdapter crashes on application launch

Question

Data being pulled from a local DB, then mapped using a cursor. Custom Adapter displays data similar to a ListView. As items are added/deleted from the DB, the adapter is supposed to refresh. The solution attempted below crashes the application at launch. Any suggestions?

Thanks in advance, -D

 @Override
 public View getView(int position, View convertView, ViewGroup parent) {
   View v = convertView;
   ViewGroup p = parent;            
   if (v == null) {
     LayoutInflater vi = (LayoutInflater)context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
     v = vi.inflate(R.layout.items_row, p);
   }
   int size = mAdapter.getCount();
   Log.d(TAG, "position " + position + " Size " + size);
   if(size != 0){
     if(position < size) return mAdapter.getView(position, v, p);
     Log.d(TAG, "-position " + position + " Size " + size);
   }
   return null;
 }

Answer 1

v = vi.inflate(R.layout.items_row, p);

Add a false third parameter to that call, and I think your problem will go away. The call should become:

v = vi.inflate(R.layout.items_row, p, false);

This is the answer! I had this issue already but I'd forgotten to put in the extra false parameter this time since it's been a while and sure enough this fixed it right up. – Egyptian

Answer 2

change this code

v = vi.inflate(R.layout.items_row, p);

to

v = vi.inflate(R.layout.items_row, null );
