如何在android中显示之前从到达通知中获取数据

<receiver android:name=".NotificationReceiver" />

NotificationCompat.Builder builder = new NotificationCompat.Builder(context, channelId)
        .setSmallIcon(R.drawable.notification_icon)
        .setContentTitle("Notification Title")
        .setContentText("Notification Content")
        .setAutoCancel(true);

// 添加数据到通知的 extras
Bundle extras = new Bundle();
extras.putString("key", "value");
builder.setExtras(extras);

// 发送通知
NotificationManager notificationManager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
notificationManager.notify(notificationId, builder.build());

@Override
public void onReceive(Context context, Intent intent) {
    // 获取通知的 extras
    Bundle extras = intent.getExtras();
    if (extras != null) {
        String data = extras.getString("key");
        // 在这里可以对获取到的数据进行处理，例如显示在界面上
        // ...
    }
}
