Android Json 解析

標籤：

方法一 使用API解析

json：

{"beaconid":"2397","state":"01","userid":"90"}

擷取json的方法

 private void sendRequestWithHttpClient(){                new Thread(new Runnable() {                  @Override                  public void run() {                                                    try {                                 // HttpClient對象                              HttpClient httpClient = new DefaultHttpClient();                                 // HttpGet對象                              HttpGet httpGet = new HttpGet("http://192.168.0.103/test.json");                              HttpResponse httpResponse = httpClient.execute(httpGet);                              if (httpResponse.getStatusLine().getStatusCode() == 200) {                                  HttpEntity entity = httpResponse.getEntity();                                  // 取得返回的資料                                  String response = EntityUtils.toString(entity, "utf-8");
                                  //解析json                                  parseJSONWithJSONObject(response);                              }                          } catch (IOException e) {                              e.printStackTrace();                          }                      }              }).start();      }

解析json的方法

 private void parseJSONWithJSONObject (String jsonData){        try {            JSONObject jsonObj = new JSONObject(jsonData);            String beaconid = jsonObj.getString("beaconid");            String state = jsonObj.getString("state");            String uid = jsonObj.getString("userid");            Log.d("beaconid","beaconid is"+" "+beaconid);            Log.d("state","state is"+ " "+state);            Log.d("userid","userid is"+ " "+uid);        } catch (JSONException e) {            e.printStackTrace();        }    }

最後在MainActivity 調用 sendRequestWithHttpClient() 方法；

記得在AndroidMainfest.xml

<uses-permission android:name="android.permission.INTERNET" />    <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />    <uses-permission android:name="android.permission.VIBRATE" />    <uses-permission android:name="android.hardware.sensor.accelerometer" />
