                mShop=Shopinfo;
                String[] spots = new String[mShop.size()];
                int i = 0;
                for(ParseObject Shopinfos : mShop) {
                    spots[i] =  Shopinfos.getString(ParseConstants.KEY_SHOP_NAME);
                    i++;

                if (getListView().getAdapter() == null) {
                    adapter=new ShopListAdapter(list.getContext(), mShop);
                    setListAdapter(adapter);
                }
                else {
                    ((ShopListAdapter)getListView().getAdapter()).refill(mShop);
                }

            }

        }
    });

回答1:

Move the following to onActivityCreated() method or in onViewCreated().

    @Override
    public void onActivityCreated(Bundle savedInstanceState) {
        super.onActivityCreated(savedInstanceState);
    ParseQuery<ParseObject> query = new ParseQuery<ParseObject>("Shopinfo");
    query.findInBackground(new FindCallback<ParseObject>() {

        @Override
        public void done(List<ParseObject> Shopinfo, ParseException e) {
            // TODO Auto-generated method stub
            if(e==null){
                mShop=Shopinfo;
                String[] spots = new String[mShop.size()];
                int i = 0;
                for(ParseObject Shopinfos : mShop) {
                    spots[i] =  Shopinfos.getString(ParseConstants.KEY_SHOP_NAME);
                    i++;
                }

                if (getListView().getAdapter() == null) {
                    adapter=new ShopListAdapter(list.getContext(), mShop);
                    setListAdapter(adapter);
                }
                else {
                    ((ShopListAdapter)getListView().getAdapter()).refill(mShop);
                }

            }

        }
    });
    }

A good practice is to put everything that uses UI widgets inside onActivityCreated() method.
