方法一 使用API解析
json：
{"beaconid":"2397","state":"01","userid":"90"}
获取json的方法
private void sendRequestWithHttpClient(){ new Thread(new Runnable() { @Override public void run() { try { // HttpClient对象 HttpClient httpClient = new DefaultHttpClient(); // HttpGet对象 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(); // 取得返回的数据 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(); } }
最后在MainActivity 调用 sendRequestWithHttpClient() 方法；
记得在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" />
