方法一 使用API解析

json：

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

獲取json的方法

private void sendRequestWithHttpClient(){new Thread(new Runnable() {@Overridepublic 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(); // 取得返回的數據String response = EntityUtils.toString(entity, "utf-8");
//解析jsonparseJSONWithJSONObject(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();}}

最后在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" />
