从捆绑中提取数据

Question

AWS SNS正在向

发送有效负载

@Override
public void onMessageReceived(final String from, final Bundle data) {
    String message = getMessage(data);
    Log.d(LOG_TAG, "Message: " + message);

    int timeToLive = data.getInt("time_to_live");
    Log.d(LOG_TAG, "time_to_live: " + timeToLive);

    String text = data.getString("text");
    Log.d(LOG_TAG, "Text: " + text);

消息采用

的形式

PushListenerService: Message: {
                           "condition": "normal”,
                           "priority" : "normal",
                           "time_to_live" : 0,
                           "notification" : {
                               "body" : “random gibberish”,
                               "title" : "TEST TITLE”,
                               "icon" : “ic_launcher”
                           },
                           "data" : {
                               “GeoHash” : 1,
                               "text" : "TEST TEXT”
                           }
                       }
D/PushListenerService: time_to_live: 0
D/PushListenerService: Text: null

如何从中提取数据？我希望PushListener返回Text：TEST TEXT。我可以查询类似于查询json的包吗？正则表达式？

getMessage方法：

public static String getMessage(Bundle data) {
    return data.containsKey("default") ? data.getString("default") : data.getString(
        "message", "");
}

你不能做这样的事情：

Bundle payload = data.getBundle("data");
String text = payload.getString("text");
