Question

我从Api收到一条文本，我想将其显示为通知，该怎么办？这是我有通知代码的代码和获取json对象的代码。

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.pushnotifications);
NotificationCompat.Builder mBuilder =   new NotificationCompat.Builder(this)
            .setSmallIcon(R.drawable.ic_launcher_background) // notification icon
            .setContentTitle("Notification!") // title for notification
            .setContentText("Hello word"); // message for notification

    Notification mNotificationManager = mBuilder.build();
    NotificationManagerCompat.from(this).notify(0,mNotificationManager);

    URL obj = null;
    try {
        obj = new URL("https://gekon.technologypark.cz/api/v1/notification/demo/8");
        HttpsURLConnection conn = (HttpsURLConnection) obj.openConnection();
        conn.setRequestMethod("POST");
        conn.setRequestProperty("ApiSecret", LoginInfo.ApiSecret);
        conn.connect();
        BufferedReader br = new BufferedReader(new InputStreamReader((conn.getInputStream())));
        StringBuilder sb = new StringBuilder();
        String output;
        while ((output = br.readLine()) != null)
            sb.append(output);

        JSONObject jsonObj = new JSONObject(sb.toString());

        String notifText=(String) jsonObj.get("data");

        Log.d("log","PUSH NANI"+notifText);


    } catch (Exception e) {
        e.printStackTrace();
        Log.d("log","PUSH CATCG"+e);

    }

}

在api成功内调用您的通知代码，看看

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.pushnotifications);


    URL obj = null;
    try {
        obj = new URL("https://gekon.technologypark.cz/api/v1/notification/demo/8");
        HttpsURLConnection conn = (HttpsURLConnection) obj.openConnection();
        conn.setRequestMethod("POST");
        conn.setRequestProperty("ApiSecret", LoginInfo.ApiSecret);
        conn.connect();
        BufferedReader br = new BufferedReader(new InputStreamReader((conn.getInputStream())));
        StringBuilder sb = new StringBuilder();
        String output;
        while ((output = br.readLine()) != null)
            sb.append(output);

        JSONObject jsonObj = new JSONObject(sb.toString());

        String notifText=(String) jsonObj.get("data");

        Log.d("log","PUSH NANI"+notifText);
         showNotification(notiftext)


    } catch (Exception e) {
        e.printStackTrace();
        Log.d("log","PUSH CATCG"+e);

    }

}

这是在成功调用api后显示通知的方法。

public void showNotification(String message){
NotificationCompat.Builder mBuilder =   new NotificationCompat.Builder(this)
                .setSmallIcon(R.drawable.ic_launcher_background) // notification icon
                .setContentTitle("Notification!") // title for notification
                .setContentText(message); // message for notification

       NotificationManager mNotificationManager =
        (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
       NotificationManager.notify().
      mNotificationManager.notify(001, mBuilder.build());
}

希望它将对您有帮助！
