我有一个问题，当点击“商店”或“bukukoleksi”并单击“登录”后，无法导航到页面“商店”页面或“Koleksi”页面。必须再次点击“商店”或“koleksibuku”才能导航到“商店”和“Koleksi”页面。如何处理

我有一个问题，当点击“商店”或“bukukoleksi”并单击“登录”后，无法导航到页面“商店”页面或“Koleksi”页面

导航操作由点击的

事件调用，单击loginBtn
后，导航操作不应自动触发。处理此问题的一个简单方法是创建bool变量，以在单击loginbtn
之前标记要点击的图像。例如，创建了两个变量isstoreTapped
，iskoleksiTapped
，一旦存储tapped，将isstoreTapped
设置为true，与“koleksi”相同。登录后，通过两个标志判断要导航的页面
  bool isstoreTapped = false;
  bool iskoleksiTapped = false;
