好吧,我有点基础知识。我有一个方法在类中显示通知栏中的通知。我试图让它变成静态的,但如果我将它变成静态的,一些函数将不起作用。如何从不同的类访问
所以,如果我在x.class中有以下功能,我怎样才能从y.class访问它?因为我用静态和对象尝试过,但都失败了。
void notify(String i) {
String ns = Context.NOTIFICATION_SERVICE;
NotificationManager mNotificationManager = (NotificationManager) getSystemService(ns);
int icon = R.drawable.icon; // icon from resources
CharSequence tickerText = "gogu la telefon"; // ticker-text
long when = System.currentTimeMillis(); // notification time
Context context = getApplicationContext(); // application Context
CharSequence contentTitle = "My notification"; // message title
CharSequence contentText = "Hello World!"; // message text
Intent notificationIntent = new Intent(this, MilkyWaySearcherActivity.class);
PendingIntent contentIntent = PendingIntent.getActivity(this, 0, notificationIntent, 0);
// the next two lines initialize the Notification, using the configurations above
Notification notification = new Notification(icon, tickerText, when);
notification.setLatestEventInfo(context, contentTitle, contentText, contentIntent);
notification.ledARGB = 0xff00ff00;
notification.ledOnMS = 300;
notification.ledOffMS = 1000;
notification.flags |= Notification.FLAG_SHOW_LIGHTS;
mNotificationManager.notify(BIND_AUTO_CREATE, notification);
}
getApplicationContext();我也不能使用这个...如果我把它做成静态的 – user1015311
你需要的任何实例化变量都可以通过方法的参数传入。如果你需要一个'Context',把你的方法改为'void notify(String i,Context context)' –
它与参数一起工作......太愚蠢了,我没有想到。谢谢! – user1015311
