我的通知未检索待处理意图中的附加内容

Question

我已经尝试了大多数解决方案，但是当单击通知时我仍然没有得到附加信息 我尝试了1 为什么 PendingIntent 没有发回我的 Intent 自定义附加设置？ 2 Intent.getExtras() 总是返回 null

                String itemID = dataSnapshot.child("itemID").getValue(String.class);
                Intent intent = new Intent(UserHomeActivity.this, MapsActivity.class);
                intent.putExtra("id", itemID);
                intent.setAction(itemID);
                intent.addFlags(Intent.FLAG_ACTIVITY_SINGLE_TOP | Intent.FLAG_ACTIVITY_CLEAR_TOP);

                int uniqueInt = (int) (System.currentTimeMillis() & 0xfffffff);
                PendingIntent pendingIntent = PendingIntent.getActivity(UserHomeActivity.this, 0,
                        intent, PendingIntent.FLAG_UPDATE_CURRENT);
                if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O ){
                    CharSequence name ="001";
                    NotificationChannel notificationChannel = new NotificationChannel(Channel_ID, name,NotificationManager.IMPORTANCE_HIGH );
                    notificationChannel.setDescription("This is description");

                    NotificationManager notificationManager = (NotificationManager)getSystemService(NOTIFICATION_SERVICE);
                    notificationManager.createNotificationChannel(notificationChannel);

                    Notification.Builder builder = new Notification.Builder(getApplicationContext(),Channel_ID);
                    builder.setSmallIcon(R.mipmap.ic_launcher)
                            .setContentText(text)
                            .setContentTitle("New Price Added")
                            .setContentIntent(pendingIntent)
                            .setPriority(Notification.PRIORITY_DEFAULT);
                    NotificationManagerCompat  notificationManagerCompat = NotificationManagerCompat.from(getApplicationContext());
                    notificationManagerCompat.notify(001,builder.build());

                }else {
                    Notification.Builder builder = new Notification.Builder(getApplicationContext());
                    builder.setSmallIcon(R.mipmap.ic_launcher)
                            .setContentText(text)
                            .setContentTitle("New Price Added")
                            .setAutoCancel(true)
                            .setContentIntent(pendingIntent)
                            .setPriority(Notification.PRIORITY_MAX);
                    NotificationManagerCompat  notificationManagerCompat = NotificationManagerCompat.from(getApplicationContext());
                    notificationManagerCompat.notify(uniqueInt,builder.build());

这是我用于检索附加内容的代码

        if(extras != null){
                // extract the extra-data in the Notification
                String msg = extras.getString("id");
                String sss = getIntent().getParcelableExtra("id");
            Toast.makeText(this, sss+" ids  "+msg+ "     "+extras.toString(), Toast.LENGTH_SHORT).show();

        }
        imageButton = findViewById(R.id.call);
        imageButton.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                Intent phoneIntent = new Intent(Intent.ACTION_DIAL);
                phoneIntent.setData(Uri.parse("tel:0818283848"));
                startActivity(phoneIntent);
            }
        });     ```

您是否尝试调试附加功能？ 尝试设置断点并查看您通过意图收到的内容。 检查额外的是否真的通过了。

如果你没有收到额外的，那么你的意图是错误的。 如果您收到的是额外的，那么您如何访问额外的逻辑是错误的。
