添加添加到谷歌地图，然后搜索它

Question

我是谷歌地图和谷歌地图 api 的新手 我想知道我的 android 应用程序如何将数据添加到谷歌地图“像位置” 然后其他用户可以在最近的搜索请求中获取此位置
换句话说

我的应用程序将允许人们将他们的位置添加到我的谷歌地图，并允许用户按位置搜索到其他用户添加的最近位置，而不仅仅是谷歌地方库 因此应用程序可以获取包含用户位置附近最近位置的 json 文件

我如何使用 Google API 做到这一点？

// Fetches all places from GooglePlaces AutoComplete Web Service
private class PlacesTask extends AsyncTask<String, Void, String>{

    @Override
    protected String doInBackground(String... place) {
        // For storing data from web service
        String data = "";

        // Obtain browser key from https://code.google.com/apis/console
        String key = "key=key";

        String input="";

        try {
            input = "input=" + URLEncoder.encode(place[0], "utf-8");
        } catch (UnsupportedEncodingException e1) {
            e1.printStackTrace();
        }       


        // place type to be searched
        String types = "types=geocode";

        // Sensor enabled
        String sensor = "sensor=false";         

        // Building the parameters to the web service
        String parameters = input+"&"+types+"&"+sensor+"&"+key;

        // Output format
        String output = "json";

        // Building the url to the web service
        String url = "https://maps.googleapis.com/maps/api/place/autocomplete/"+output+"?"+parameters;

        try{
            // Fetching the data from web service in background
            data = downloadUrl(url);
        }catch(Exception e){
            Log.d("Background Task",e.toString());
        }
        return data;        
    }

    @Override
    protected void onPostExecute(String result) {           
        super.onPostExecute(result);

        // Creating ParserTask
        parserTask = new ParserTask();

        // Starting Parsing the JSON string returned by Web Service
        parserTask.execute(result);
    }       
}


/** A class to parse the Google Places in JSON format */
private class ParserTask extends AsyncTask<String, Integer, List<HashMap<String,String>>>{

    JSONObject jObject;

    @Override
    protected List<HashMap<String, String>> doInBackground(String... jsonData) {            

        List<HashMap<String, String>> places = null;

        PlaceJSONParser placeJsonParser = new PlaceJSONParser();

        try{
            jObject = new JSONObject(jsonData[0]);

            // Getting the parsed data as a List construct
            places = placeJsonParser.parse(jObject);

        }catch(Exception e){
            Log.d("Exception",e.toString());
        }
        return places;
    }

    @Override
    protected void onPostExecute(List<HashMap<String, String>> result) {            

            String[] from = new String[] { "description"};
            int[] to = new int[] { android.R.id.text1 };

            // Creating a SimpleAdapter for the AutoCompleteTextView            
            SimpleAdapter adapter = new SimpleAdapter(getBaseContext(), result, android.R.layout.simple_list_item_1, from, to);             

            // Setting the adapter
            atvPlaces.setAdapter(adapter);
    }           
}
