这个我很难受...

我有数据从 pubnub 连接进入服务

public void Startpubnub() {
Toast.makeText(this, "PubnubService created...", Toast.LENGTH_LONG).show();
Log.i("PUBNUB", "PubnubService created...");
try {
    pubnub.subscribe(new String[] {channel}, new Callback() {
        public void connectCallback(String channel) {

            notifyUser("CONNECT on channel:" + channel);
        }
        public void disconnectCallback(String channel) {
            notifyUser("DISCONNECT on channel:" + channel);
        }
        *public void reconnectCallback(String channel) {
            notifyUser("RECONNECT on channel:" + channel);
        }
        @**Override
        public void successCallback(String channel, Object message) {
            Log.i("tag","broadcast is sent!");
            //notifyUser(channel + " " + message.toString());
            Gson gson = new Gson();
            String jsonMessage = gson.toJson(message);
            System.out.printf("tag",jsonMessage);
            JSONObject json = null;
            try {
                json = new JSONObject(jsonMessage);
            } catch (JSONException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            }
            System.out.printf("tag",json);
            String data = null;
            try {
                data = json.getString("data");
            } catch (JSONException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            }
            Log.i("tag",data);**

        }*

在 successCallback 中，我试图将传入消息解析为 jsonobject 并将附加信息发送到广播接收器。

我很难理解如何解析...对象消息。

这是传入消息的格式：

        5 info = pubnub.publish({
        6     'channel' : 'somechannel',
        7     'message' : {
        8         'data' : 'Hello my World',
        9         'data2' : 'yup',
        10         'data3' : 'yupyup'
        11     }
        12 })

我最终使用了这个......来自将json发送到广播接收器类的服务。这很冗长。但并不真正了解如何实现@bhagat 的答案....

        private void broadcastMessage(JSONObject message) { 
    String msg = null;
    try {
    msg = message.getString("action");
} catch (JSONException e) {
    // TODO Auto-generated catch block
    e.printStackTrace();
}
    Intent intent = new Intent(msg);
    intent.putExtra("message", message.toString());
    sendBroadcast(intent);
}

class MessageHandler extends Handler {
    @Override
    public void handleMessage(Message msg) {
        try {
            String m = msg.getData().getString("message");
            Log.i("handleMessage", m);
            JSONObject message = (JSONObject) new JSONTokener(m).nextValue();
            broadcastMessage(message);
        } catch (JSONException e) {
            e.printStackTrace();
        }

    }

};
    @Override
        public void successCallback(String channel, Object message) {
            Log.i("tag","broadcast is sent!");
            notifyUser(channel + " " + message.toString());
            Log.i("afterBroadcastisSent", message.toString());
            try {
                Message m = Message.obtain();
                Bundle b = new Bundle();
                b.putString("message", message.toString());
                m.setData(b);
                mMessageHandler.sendMessage(m);
            } catch (Exception e) {
                e.printStackTrace();
            }
        }

尝试这样的事情：

import org.json.JSONObject;
public void callback(JSONObject data) {
    try {
        String dt = data.getString("data");
        String dt = data.getString("data1");
    } catch (Exception e) {}
}
