【中文标题】如何在通知选项卡中单击推送通知消息打开特定片段？【英文标题】：How to open the particular fragment on the click of the push notification message in the notification tab? 【发布时间】：2016-09-07 12:35:58 【问题描述】：这是我发送消息的GcmIntentService 类。问题是当我单击推送通知消息时，它会打开主要活动。但我想打开特定的片段。我知道sendNotification()method 中会有一些更改。谁能告诉我如何在点击推送通知时打开特定片段？
public class GcmIntentService extends IntentService
public static final int NOTIFICATION_ID = 1;
private NotificationManager mNotificationManager;
private final static String TAG = "GcmIntentService";
public GcmIntentService()
super("GcmIntentService");
@Override
protected void onHandleIntent(Intent intent)
Bundle extras = intent.getExtras();
GoogleCloudMessaging gcm = GoogleCloudMessaging.getInstance(this);
String messageType = gcm.getMessageType(intent);
if (!extras.isEmpty())
if (GoogleCloudMessaging.MESSAGE_TYPE_SEND_ERROR
.equals(messageType))
sendNotification("Send error: " + extras.toString());
else if (GoogleCloudMessaging.MESSAGE_TYPE_DELETED
.equals(messageType))
sendNotification("Deleted messages on server: " + extras.toString());
else if (GoogleCloudMessaging.MESSAGE_TYPE_MESSAGE
.equals(messageType))
for (int i = 0; i < 5; i++)
Log.d(TAG, " Working... " + (i + 1) + "/5 @ "
+ SystemClock.elapsedRealtime());
try
Thread.sleep(5000);
catch (InterruptedException e)
e.printStackTrace();
sendNotification(extras.getString("message"));
WakefulBroadcastReceiver.
GcmBroadcastReceiver.completeWakefulIntent(intent);
private void sendNotification(String msg)
mNotificationManager = (NotificationManager) this
.getSystemService(Context.NOTIFICATION_SERVICE);
PendingIntent contentIntent = PendingIntent.getActivity(this, 0, new Intent(this, MainActivity.class), 0);
NotificationCompat.Builder mBuilder = (NotificationCompat.Builder) new NotificationCompat.Builder(this)
.setSmallIcon(getNotificationIcon())
.setContentTitle("Telepoh")
.setStyle(new NotificationCompat.BigTextStyle().bigText(msg))
.setContentText(msg)
.setDefaults(Notification.DEFAULT_SOUND | Notification.DEFAULT_VIBRATE);
mBuilder.setContentIntent(contentIntent);
mBuilder.getNotification().flags |= Notification.FLAG_AUTO_CANCEL;
mBuilder.setAutoCancel(true);
mNotificationManager.notify(NOTIFICATION_ID, mBuilder.build());
private int getNotificationIcon()
boolean useWhiteIcon = (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP);
return useWhiteIcon ? R.drawable.gcm : R.drawable.push_icon;
这是我想在点击推送通知消息时打开的片段：-

【问题讨论】：
【参考方案1】：管理一些标志并通过Intent将通知中的信息传递给MainActivity。
在MainActivity 中使用 switch case 或 if/else，如果您收到特定的标志/数据，请加载所需的片段。
Intent passIntent = new Intent(this, MainActivity.class);
passIntent.putExtra("flag","some value");
PendingIntent contentIntent = PendingIntent.getActivity(this, 0, passIntent, 0);
在您的 MainActivity.java 中
if(getIntent().hasExtra("flag"))
if(getIntent.getStringExtra("flag").equalsIgnorCase("some value"))
//write code to load your fragment.
【讨论】：
亲爱的先生，它不工作。当我点击通知消息时没有加载片段。而不是片段主要活动正在打开。 你能告诉我主要活动的哪个方法我得到了意图并加载片段。我在 create() 方法中完成了这项工作。以上是关于如何在通知选项卡中单击推送通知消息打开特定片段？的主要内容，如果未能解决你的问题，请参考以下文章
