编辑器.getBoolean让我无法解决错误！ 我该怎么办???
答案 0 :(得分：1)
您需要在某处保存交换机的值（SQLite或SharedPreferences），并检查它是否是当前的交换机值，而不是更改保留它的位置上的值在交换机上选中或取消选中
这是您创建SharedPreferences并输入值的方式：
.when("/profile", {
templateUrl : "profile.php",
controller : "profilecontroller"
}
这是检查SharedPreferences值并更改它的方法：
SharedPreferences sharedPreferences = getSharedPreferences("key", 0);
SharedPreferences.Editor editor = sharedPreferences.edit();
editor.putBoolean("switchValue", aSwitch.isChecked());
editor.apply();
如果要通知通知，则应检查SharedPreferences值：
Boolean showNotifications = editor.getBoolean("key",false);
if (aSwitch.isChecked() != showNotifications) {
editor.putBoolean("key",!showNotifications).apply();
}
已修改这是您发布通知的方式：
Boolean showNotifications = editor.getBoolean("key",false);
notification_id - 您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（如果用户点击通知）
你需要使用相同的“密钥”。那样：
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());

如果理解正确，这里的问题不是关于如何知道开关是打开还是关闭，而是关于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是 - 获取通知并决定是否提供通知。
所以你需要的是保存其他答案中提到的开关状态，但另外 - 如果用户将状态切换为OFF，则需要取消注册用户以获取通知，反之亦然，使用以下内容：
从服务器中删除包含用户FCM令牌的令牌：
// 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);
收件人
boolean showNotifications = sharedPreferences.getBoolean("key",false);
