Question

我一步一步地按照他们的教程，但我一直遇到奇怪的错误。

notifymanager没有.notify（）作为方法，其中包含notifymanager的任何代码行必须有括号，无论代码在何处。

我开始认为这是一个依赖问题，请帮忙！

                                                    "Android Example Status message!",
                                                    System.currentTimeMillis());

    // This pending intent will open after notification click
    PendingIntent i=PendingIntent.getActivity(this, 0,
                                            new Intent(this, NotifyMessage.class),
                                            0);

    note.setLatestEventInfo(this, "Android Example Notification Title",
                            "This is the android example notification message", i);

    //After uncomment this line you will see number of notification arrived
    //note.number=2;
    mgr.notify(NOTIFY_ME_ID, note);


}

    import android.widget.TextView;

public class NotifyMessage extends Activity {
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        TextView txt=new TextView(this);

        txt.setText("Activity after click on notification");
        setContentView(txt);
    }
}
