android - 如何在谷歌地图中获取解析 url 以获取有关 android 中位置和邻域的详细信息

Question

这是我的代码

public static JSONObject getLocationInfo(String address) {
                StringBuilder stringBuilder = new StringBuilder();
                try {

               // address = address.replaceAll(" ","%20");    

                HttpPost httppost = new HttpPost("http://maps.google.com/maps/api/geocode/json?address=" + address + "&sensor=false");
                HttpClient client = new DefaultHttpClient();
                HttpResponse response;
                stringBuilder = new StringBuilder();


                    response = client.execute(httppost);
                    HttpEntity entity = response.getEntity();
                    InputStream stream = entity.getContent();
                    int b;
                    while ((b = stream.read()) != -1) {
                        stringBuilder.append((char) b);
                    }
                } catch (ClientProtocolException e) {
                } catch (IOException e) {
                }

                JSONObject jsonObject = new JSONObject();
                try {
                    jsonObject = new JSONObject(stringBuilder.toString());
                } catch (JSONException e) {
                    // TODO Auto-generated catch block
                    e.printStackTrace();
                }

                return jsonObject;
            }

我在响应中收到一个 json 异常。请告诉我一个有效的网址。我还为 gps 做了 mapview(api key 和 android list 许可)。

试试这个:

    private String getJSONFile(String URL) {
    HttpGet httpGet = new HttpGet(URL);
    HttpClient httpClient = new DefaultHttpClient();
    HttpResponse httpResponse;
    StringBuilder stringBuilder = new StringBuilder();

    try {
        httpResponse = httpClient.execute(httpGet);
        HttpEntity httpEntity = httpResponse.getEntity();
        InputStream inputStream = httpEntity.getContent();
        int c;
        while ((c = inputStream.read()) != -1) {
            stringBuilder.append((char) c);
        }
    } catch (Exception e) {
        e.printStackTrace();
    }

    return stringBuilder.toString();
}
