我想在通知上设置onclick，以转到我从后端获取的特定活动。（FireBase）。目前，当我点击通知时，它打开应用程序启动器活动。
答案 0 :(得分：0)
请在此处检查 MyFirebaseMessagingService 文件我设置onclick并打开其他活动： -
首先是＃34; if（json instanceof JSONObject）{＆＃34;条件得到来自通知的json响应的响应，然后打开评论活动。
在＆＃34; else＆＃34;获得简单的消息并在通知上显示并从Splash Screen重新启动应用程序。
public class MyFirebaseMessagingService extends FirebaseMessagingService { private static final String TAG = "MyFirebaseMsgService"; Context mContext; /** * Called when message is received. * * @param remoteMessage Object representing the message received from Firebase Cloud Messaging. */ // [START receive_message] @Override public void onMessageReceived(RemoteMessage remoteMessage) { // TODO(developer): Handle FCM messages here.

希望它可以帮助你。

如果您从后端发送{"notification":""}数据，android会自动在通知栏中显示通知（仅当您集成了FCM sdk时）。
如果你想控制通知，不要从后端发送通知对象，只发送数据对象（如果你从firebase控制台发送通知进行测试，通知对象将默认存在）
每当您发送没有通知对象的通知时，都会执行onMessageReceived()方法
@Override
public void onMessageReceived(RemoteMessage remoteMessage) {
String data=remoteMessage.getData();
//parse data and show notification
showNotification(parsedMessageData);
}
private void sendNotification(String message) {
Intent intent = new Intent(this, MainActivity.class);
intent.putExtra("showNotification", true);
intent.putExtra("params", params);
if (page != null && page.equals(VIEW_INDENT)) {
intent.putExtra("page", HomeNavigationController.DISPLAY_INDENT_TAG);
}else if(page != null && page.equals(PAYMENT_SUMMERY)){
intent.putExtra("page", HomeNavigationController.DISPLAY_PAYMENT_SUMMERY_TAG);
intent.putExtra("month",paymentParams.getMonth());
intent.putExtra("year",paymentParams.getYear());
intent.putExtra("slotId",paymentParams.getSlotId());
}
else {
intent.putExtra("page", HomeNavigationController.PRODUCT_LIST_TAG);
}
intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
PendingIntent pendingIntent = PendingIntent.getActivity(this, 0 /* Request code */, intent,
PendingIntent.FLAG_ONE_SHOT);
Uri defaultSoundUri = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(this)
.setSmallIcon(R.drawable.farm_taaza_logo)
.setContentTitle("Sample Notification")
.setStyle(new NotificationCompat.BigTextStyle().bigText(message))
.setContentText(message)
.setAutoCancel(true)
.setSound(defaultSoundUri)
.setContentIntent(pendingIntent);
NotificationManager notificationManager =
(NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
notificationManager.notify(0 /* ID of notification */, notificationBuilder.build());
}
主要活动将以传递的参数作为putExtra启动，然后您可以根据参数传递到相应的活动。
