Question

我正在尝试使用地址填充列表视图，方法是在附近的位置运行查询，从点g到解析服务器中的地址/ geopoint列表。：

public class Map_Masti extends FragmentActivity {
    ParseGeoPoint g;
    private SupportMapFragment mapFragment;
    private TextView textView;
    private  ParseQueryAdapter<Rahees> adapter;
    private ParseQueryAdapter<Rahees> postsQueryAdapter;//this is outside oncreate
  private List <ParseGeoPoint> points=new ArrayList<ParseGeoPoint>();



    private void getG() {
        ParseQuery<ParseUser> query = ParseUser.getQuery();
        query.getInBackground("ccm3xKMmr4", new GetCallback<ParseUser>() {
            public void done(ParseUser object, ParseException e) {
                if (e == null) {
                    g = (ParseGeoPoint) object.get("user_Location");

                    display();


                } else {


                }
            }
        });
    }



    public void display()
    {


        // Set up a customized query
        ParseQueryAdapter.QueryFactory<Rahees> factory =
                new ParseQueryAdapter.QueryFactory<Rahees>() {
                    public ParseQuery<Rahees> create() {                    
                        ParseQuery<Rahees> query = Rahees.getQuery();

                        query.include("user");
                        query.whereWithinKilometers("Locations", g, 1000);

                        query.findInBackground(new FindCallback<Rahees>() {//here is the error
                            @Override
                            public void done(List<Rahees> objects, ParseException e) {
                                //to check if there is a result


                                } 
                            }
                        });
                        return query;
                    }
                };




        // Set up the query adapter
        postsQueryAdapter = new ParseQueryAdapter<Rahees>(this, factory) {
            @Override
            public View getItemView(Rahees post, View view, ViewGroup parent) {
                if (view == null) {

                    view = View.inflate(getContext(), R.layout.row1_of_listvew, null);
                }
                TextView contentView = (TextView) view.findViewById(R.id.textView1);
                TextView usernameView = (TextView) view.findViewById(R.id.textView2);
                contentView.setText(post.getInt("Address"));
                usernameView.setText(post.getInt("Address"));
                return view;
            }
        };




        postsQueryAdapter.setAutoload(false);

// ***************************Disable pagination, we'll manage the query limit ourselves********************************/


        postsQueryAdapter.setPaginationEnabled(false);


        //********************************** Attach the query adapter to the view/

        ListView postsListView = (ListView) findViewById(R.id.listview);

        postsListView.setAdapter(postsQueryAdapter);

        postsQueryAdapter.loadObjects();

    }

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.map_masti);
        textView = (TextView) findViewById(R.id.text);
        mapFragment = (SupportMapFragment) getSupportFragmentManager().findFragmentById(R.id.map_fragment);
      getG();
    }
}
 //****************************************************************************//

以下是我得到的错误

Parse的新手，所以不太确定，只是按照指南中的说明进行操作。

Answer 1

您应该尝试再次卸载并重新安装该应用。这至少解决了我的问题。

您可以尝试的另一件事是删除并重新创建您要查询的对象或类。

告诉我这是否有效。

Answer 2

我不应该在工厂查询中添加查询的执行，下面的部分：query.findInBackground（new FindCallback（）{//这里是错误@Override public void done（List objects，ParseException e）{//检查是否有结果}}}）;

java.lang.RuntimeException：此查询具有出色的网络连接。你必须等到它完成
