通知栏跳转问题

点击通知栏进行跳转到相应的Activity：

Notification notification = new Notification(R.drawable.ic_launcher, “Hello”, System.currentTimeMillis()); 

PendingIntent pendingIntent = PendingIntent.getActivity( 
ActivityA.this, 
0, 
new Intent(ActivityA.this, ActivityB.class), PendingIntent.FLAG_CANCEL_CURRENT
);
/*通过设置PendingIntent就能跳转到ActivityB啦*/
notification.contentIntent = pendingIntent;

希望能帮助到你。
