谢谢!!希望你能帮助我
editor.getBoolean给了我无法解决的错误!!!
我能做些什么?您需要将开关的值保存在某个位置(SQLite或SharedReferences)并检查它是否为当前开关值,而不是在开关处于选中或未选中状态时更改该值 以下是创建SharedReference并输入值的方式:
SharedPreferences sharedPreferences = getSharedPreferences("key", 0);
SharedPreferences.Editor editor = sharedPreferences.edit();
editor.putBoolean("switchValue", aSwitch.isChecked());
editor.apply();
以下是检查SharedReferences值并对其进行更改的方式:
Boolean showNotifications = editor.getBoolean("key",false);
if (aSwitch.isChecked() != showNotifications) {
editor.putBoolean("key",!showNotifications).apply();
}
如果要通知通知,应检查SharedReferences值:
Boolean showNotifications = editor.getBoolean("key",false);
已编辑这是您触发通知的方式:
NotificationCompat.Builder mBuilder = new
NotificationCompat.Builder(context)
.setSmallIcon(R.drawable.your_drawable)
.setStyle(new NotificationCompat.BigTextStyle().bigText("notification text"))
.setContentText(notificationToNotify.getText())
.setContentTitle(CaseFormat.UPPER_UNDERSCORE.to(CaseFormat.UPPER_CAMEL, "notification title"))
.setContentIntent(contentPendingIntent)
.setDeleteIntent(deletePendingIntent)
.setAutoCancel(true);
//notify the Notification
mNotifyMgr.notify(notification_id, mBuilder.build());
notification_id-可以为每个通知提供的int id。
您可以设置删除意图和内容意图(如果用户单击通知)
伙计,你需要用同样的“钥匙”。就像这样:
SharedPreferences sharedPreferences =
getActivity().getSharedPreferences("key", 0);
SharedPreferences.Editor editor = sharedPreferences.edit();
editor.putBoolean("**switchValue**", aSwitch.isChecked());
editor.apply();
boolean showNotifications =
editor.getBoolean("**switchValue**",false);
如果理解正确,这里的问题不是如何知道开关是打开还是关闭,而是如何避免根据开关状态获取推送通知 您希望避免收到通知而不收到-收到通知并决定是否提交 因此,您需要的是保存其他答案中提到的切换状态,但除此之外-如果用户将状态切换为“关闭”,则需要使用以下命令注销用户获取通知的权限,反之亦然: 从保存用户FCM令牌的服务器中删除令牌:
// Remove user from notification messages
InstanceID.getInstance(context).deleteInstanceID();
// Register user back to get notifications
FirebaseInstanceId.getInstance().getToken() // This will call the onTokenRefresh() method which will call your implementation that calls your FCM server and update the new user's token
或者如果此用户已注册到特定的通知主题
// Unregister him from the topic
FirebaseMessaging.getInstance().unsubscribeToTopic("news");
// Register him back in case switch is on
FirebaseMessaging.getInstance().subscribeToTopic("news");
boolean showNotifications=editor.getBoolean(“key”,false);
到
我假设你希望有人来代替你做这件事,但这样不行。因此,您需要将开关的值保存在某个位置(true或false),并在显示通知之前进行检查。如果该值为true,则显示它。否则-不,这是应该做的,但我怎么做通知本身?哈哈,如果你问如何从服务器端发送/不发送通知,你需要在这里添加你正在使用的服务器端技术(NodeJS、PHP、C#、Java等),然后你将能够得到帮助-但这似乎是另一个问题。是的,这应该可以做到,但我如何制作通知本身?HahayYou可以检查MainActivity的每个onResume或onCreate,以及用户是否需要通知。真是太棒了。非常感谢你,我会试试看,稍后再给你确认!嘿,无法获取“editor.getBoolean”它说它无法解决在片段中执行它的问题。您是否编写了:SharedReferences SharedReferences=GetSharedReferences(“键”,0);SharedReferences.Editor=SharedReferences.edit();在你使用编辑器之前?
// Unregister him from the topic
FirebaseMessaging.getInstance().unsubscribeToTopic("news");
// Register him back in case switch is on
FirebaseMessaging.getInstance().subscribeToTopic("news");
boolean showNotifications = sharedPreferences.getBoolean("key",false);
