Google Places API獲取Android中附近地點的距離

Question

我找不到在android中根據距離對我最近的地方進行排序的方法。 我還想在列表視圖上用地點名稱顯示該距離。 誰能幫我做到這一點。

這是我搜索地點的功能：

public PlacesList search(double latitude, double longitude, double radius, String types)
        throws Exception {

    this._latitude = latitude;
    this._longitude = longitude;
    this._radius = radius;

    try {

        HttpRequestFactory httpRequestFactory = createRequestFactory(HTTP_TRANSPORT);
        HttpRequest request = httpRequestFactory
                .buildGetRequest(new GenericUrl(PLACES_SEARCH_URL));
        request.getUrl().put("key", API_KEY);
        request.getUrl().put("location", _latitude + "," + _longitude);
        request.getUrl().put("radius", _radius); // in meters
        request.getUrl().put("sensor", "false");
        if(types != null)
            request.getUrl().put("types", types);

        PlacesList list = request.execute().parseAs(PlacesList.class);
        // Check log cat for places response status
        Log.d("Places Status", "" + list.status);
        return list;

    } catch (HttpResponseException e) {
        Log.e("Error:", e.getMessage());
        return null;
    }

}

嘗試添加以下內容：

request.getUrl().put("rankby", "distance");
