单击通知时如何打开“活动”

我需要使用带有点击事件的通知，我有通知方法，但此方法不会打开我的活动。

My code:

 private void sendNotification(String msg) {

        NotificationCompat.Builder mBuilder =  new NotificationCompat.Builder(this)
        .setContentTitle("EXX")
        .setSmallIcon(R.drawable.ic_launcher)
        .setStyle(new NotificationCompat.BigTextStyle()
        .bigText(msg))
        .setContentText(msg)          
        .setOngoing(true);          
    mNotificationManager.notify(NOTIFICATION_ID, mBuilder.build());
}    

这可能吗，

thanks.

对的，这是可能的。

改变你的方法，就像这样；

private void sendNotification(String msg) {
    Intent intent = new Intent(this, MainActivity.class);
    intent.putExtra("yourpackage.notifyId", NOTIFICATION_ID);
    PendingIntent pIntent = PendingIntent.getActivity(this, 0, intent,
            PendingIntent.FLAG_UPDATE_CURRENT);
    NotificationCompat.Builder mBuilder =  new NotificationCompat.Builder(this)
            .setContentTitle("EXX")
            .setSmallIcon(R.drawable.ic_launcher)
            .setStyle(new NotificationCompat.BigTextStyle()
            .bigText(msg))
            .addAction(getNotificationIcon(), "Action Button", pIntent)
            .setContentIntent(pIntent)
            .setContentText(msg)
            .setOngoing(true);
    mNotificationManager.notify(NOTIFICATION_ID, mBuilder.build());
}

并添加您的主要活动

    NotificationManager notificationmanager = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);

这段代码工作。
