如何实现Notification的弃用方法 [英] How to implement the deprecated methods of Notification

问题描述

我有一个小问题，但不知道如何解决这个问题.

I have a small problem but dont understand how to get out of this.

我创建了一个提供通知的类，但这些行被标记为已弃用:

I created a class for providing Notifications, but these lines are marked deprecated:

...
Notification notification = new Notification(icon, text, time); // deprecated in API level 11
...
notification.setLatestEventInfo(this, title, text, contentIntent); // deprecated in API level 11
...

替代方法是:

...
Notification noti = new Notification.Builder(mContext)
         .setContentTitle("New mail from " + sender.toString())
         .setContentText(subject)
         .setSmallIcon(R.drawable.new_mail)
         .setLargeIcon(aBitmap)
         .build(); // available from API level 11 and onwards
...

我可以写一个类似的代码:

Can i write a code something like:

if(API_level < 11)
{
...
    Notification notification = new Notification(icon, text, time); // deprecated in API level 11
    ...
    notification.setLatestEventInfo(this, title, text, contentIntent); // deprecated in API level 11
    ...
}

else
{
    ...
    Notification noti = new Notification.Builder(mContext)
             .setContentTitle("New mail from " + sender.toString())
             .setContentText(subject)
             .setSmallIcon(R.drawable.new_mail)
             .setLargeIcon(aBitmap)
             .build(); // available from API level 11 and onwards
    ...
}

我提供的最低 sdk 版本为8".

I providing the minimum sdk version as "8".

我确实喜欢以下内容:

int currentapiVersion = android.os.Build.VERSION.SDK_INT;
        if (currentapiVersion < android.os.Build.VERSION_CODES.HONEYCOMB){

            Notification notification = new Notification(icon, text, time);

            PendingIntent contentIntent = PendingIntent.getActivity(this, 0, new Intent(this, TaskDetails.class), 0);

            notification.setLatestEventInfo(this, title, text, contentIntent);

            notification.flags |= Notification.FLAG_AUTO_CANCEL;

            mNM.notify(NOTIFICATION, notification);
        } 
        else
        {
            // what to write here
        }

我可以为 else 部分写什么??

What can i write for else portion ??

推荐答案

这就是我最终的解决方案:

This is how i ended up to the solution:

if (currentapiVersion < android.os.Build.VERSION_CODES.HONEYCOMB) {

            notification = new Notification(icon, text, time);
            notification.setLatestEventInfo(this, title, text, contentIntent); // This method is removed from the Android 6.0
            notification.flags |= Notification.FLAG_AUTO_CANCEL;
            mNM.notify(NOTIFICATION, notification);
        } else {
            NotificationCompat.Builder builder = new NotificationCompat.Builder(
                    this);
            notification = builder.setContentIntent(contentIntent)
                    .setSmallIcon(icon).setTicker(text).setWhen(time)
                    .setAutoCancel(true).setContentTitle(title)
                    .setContentText(text).build();

            mNM.notify(NOTIFICATION, notification);
        }

上述解决方案有效.尽管如此，由于引入了 NotificationCompat.Builder 类，我们可以跳过 if 条件来检查比较当前 API 版本.因此，我们可以简单地删除 if...else 条件，然后使用:

The above solution works. Still, since, NotificationCompat.Builder class was introduced, we can skip the if condition for checking that compares current API version. So, we can simply remove the if...else condition, and go with:

NotificationCompat.Builder builder = new NotificationCompat.Builder(
                        this);
notification = builder.setContentIntent(contentIntent)
                      .setSmallIcon(icon).setTicker(text).setWhen(time)
                      .setAutoCancel(true).setContentTitle(title)
                      .setContentText(text).build();
mNM.notify(NOTIFICATION, notification);
