Question

我有一个小问题，但不明白如何摆脱这个。

我创建了一个用于提供通知的类，但这些行被标记为已弃用：

...
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
...

我可以编写类似的代码：

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
    ...
}

我提供的最小sdk版本为“8”。

修改

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
        }

我能为else部分写什么？

这就是我最终解决问题的方法：

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);
        }

修改

以上解决方案有效。但是，由于引入了NotificationCompat.Builder类，我们可以跳过用于检查比较当前API版本的if条件。因此，我们只需删除if...else条件，然后使用：

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);

这是获得关卡的正确方法。

 final int sdkVersion = Integer.parseInt(Build.VERSION.SDK);

if (sdkVersion < Build.VERSION_CODES.HONEYCOMB)
{
...
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
}
