我在想如果语句为isJellyBeanOrHigher(),但不知道如何实现它。任何关于如何解决我的问题的建议都会很有帮助。
Notification notification = new Notification.Builder(this)
.setContentTitle(
mContext.getString(R.string.ui_maps_display_notification_title))
.setContentText(
getResources().getString(
R.string.ui_maps_display_notification_content))
.setSmallIcon(R.drawable.ic_launcher).setContentIntent(pi)
.build();
mNotificationManager = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);
notification.flags = notification.flags
| Notification.FLAG_ONGOING_EVENT;
mNotificationManager.notify(0, notification);
编辑: Notification notification = new NotificationCompat.Builder(this)
.setContentTitle(
mContext.getString(R.string.ui_maps_display_notification_title))
.setContentText(
getResources().getString(
R.string.ui_maps_display_notification_content))
.setSmallIcon(R.drawable.ic_launcher).setContentIntent(pi)
.build();
mNotificationManager = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);
notification.flags = notification.flags
| Notification.FLAG_ONGOING_EVENT;
mNotificationManager.notify(0, notification);
检查应用运行的操作系统版本:
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.JELLY_BEAN) {
//do something
} else {
//do something else
}
你还必须用@TargetApi()
注释你的函数,以防止在被检查的块内调用方法时编译器发出警告。
我也同意Guardanis的观点,你应该试试NotificationCompat.Builder
检查android.os.Build.VERSION
CODENAME
:当前的开发代码,或者字符串"REL",如果这是一个发布版本。INCREMENTAL
:底层源代码控件用来表示此构建的内部值。RELEASE
:用户可见的版本字符串
