 //主線程中接收子線程發(fā)送的消息并處理
private Handler handler=new Handler(){
        @SuppressLint("HandlerLeak")
        public void handleMessage(Message msg){
            try {
                switch (msg.what){
                    case 0:
                        String Listeningresponse= msg.getData().getString("Listeningdate");
                    case 1:
                        String response = msg.getData().getString("date");
                    case 2:
                        vsnfilename=msg.getData().getString("vsndate");
                    default:
                        Log.e(TAG, " handler fail in send" );
                }
 
            }catch (Exception e){
                e.printStackTrace();
            }
        }
    };

上面代碼是在主線程中接收子線程發(fā)送的消息，根據(jù)消息標識處理后續(xù)操作。下面是子線程代碼：

開啟子線程服務：new Thread(runnable).start();

子線程執(zhí)行的任務：

 Runnable runnabletday = new Runnable(){
        @Override
        public void run() {
            try {
                //String url=ResourceMethod.UrlSplicingMinute();
                String url2=ResourceMethod.UrlSplicingDay();
                hadata=getDateFromSever(url2);
                Message msg = new Message();
                Bundle bundle =new Bundle();
                bundle.putString("date", hadata);// 這是數(shù)據(jù)標志，在接收的時候方便辨認
                msg.setData(bundle);
                msg.what = 1;
                handler.sendMessage(msg);
            } catch (Exception e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            }
        }
    };

代碼 Bundle bundle =new Bundle(); bundle.putString("date", hadata)中data是數(shù)據(jù)標識，hadata是需要發(fā)送的數(shù)據(jù)?？梢允?code>int，string，object等。msg.what = 1是設置的消息標識位，在接收消息的時候作為區(qū)分消息。

hadata=getDateFromSever(url2)是訪問url2獲取數(shù)據(jù)的方法：具體實現(xiàn)如下：

//進行http請求并獲取返回的數(shù)據(jù)
    public String getDateFromSever(String url) {
        try {
            OkHttpClient client = new OkHttpClientFactory().getInstance();
            Request request = new Request.Builder()
                    .url(url)
                    .get()
                    .build();
            Response response = client.newCall(request).execute();
            Log.d(TAG, "Ipaws response="+response);
            String responseData = response.body().string();
            if (response.isSuccessful()) {
                return responseData;
            }else {
                Log.d(TAG, "responseData: error");
            }
        } catch (Exception e) {
            e.printStackTrace();
        }
        return null;
    }
