我有一个小问题,但不明白如何解决这个问题。
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
...
我可以写一个类似的代码:
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
...
}
我提供的最低 sdk 版本为“8”。
编辑:
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??
最佳答案
这就是我最终得到解决方案的方式:
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);
}
编辑:
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 条件来检查是否比较当前 API 版本。因此,我们可以简单地删除 if...else
条件,然后继续:
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);
