Android: Custom ListAdapter extending BaseAdapter crashes on application launch
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 开发者_开发百科= (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;
}

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);
change this code
v = vi.inflate(R.layout.items_row, p);
to
v = vi.inflate(R.layout.items_row, null );
