无法从其他活动中调用方法

Question

我无法通过 OnNotificationPosted 中的其他活动调用方法。我也试图制作活动实例但失败了。我搜索了很多但没有成功。请帮忙

的NotificationListener

public class NotificationListener extends NotificationListenerService {
    @Override
    public void onCreate() {
        super.onCreate();
    }

    @Override
    public void onNotificationPosted(StatusBarNotification sbn) {
        otherActivity oth = new otherActivity();
        oth.loc();
    }

    @Override
    public void onNotificationRemoved(StatusBarNotification sbn) {
        Log.i("Msg", "Notification Removed");
    }
}

otherActivity

public class OtherActivity extends AppCompatActivity {
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_other);

    }

    public void loc() {
//code body
    }
}

如何使用：otherActivity.loc（）;

public class OtherActivity extends AppCompatActivity {
        @Override
        protected void onCreate(Bundle savedInstanceState) {
            super.onCreate(savedInstanceState);
            setContentView(R.layout.activity_other);

        }

          public static void loc(){
                //code body 
            }

    }
