推荐答案

了解视图堆叠的一种非常简单的方法是拿一本书(任何一本书).将每个页面都视为一个视图.

A very simple way of understanding stacking of views is to take a book (any book). Think of each page as a view.

可见度

• 打开书本时，您会看到一个页面(主视图-VISIBLE)
• 当您翻到当前页面时，您可以看到下一页(INVISIBLE-主视图以显示下一个视图.请记住，您只是隐藏视图，如果将可见性设置为GONE，则相当于撕裂的当前页面以查看下一页.)

• When you open the book you can see a page (Main View - VISIBLE)
• When you turn the current page you can see the next page (INVISIBLE - Main View to show the next view. Remember you are only hiding the view, if you set the visibility to GONE this is equivalent to tearing of the current page to view the next page.)

触摸场景

• 假设您的第一页是蜡质页面(类似于您的半透明视图的半透明页面)，那么您可以看到基础页面
• 当您尝试触摸第二页上的图形时，尽管您可以在第二页上看到该图形，但您正在触摸第一页.从第二页到第一页都不可能触及该图.

别灰心，因为这是您要处理的观点，而不是论文，您仍然可以做您想做的事情:)

Don't be disheartened, since it is a view you will be dealing with and not a paper you can still do what you want to do :)

• 对两个视图都实施View.OnTouchListener
• 要半透明查看您收到的任何触摸事件，请在方法onTouch
中返回FALSE
• Android会将touch事件传递给您的基础视图.

• Implement View.OnTouchListener for both your views
• For translucent view any touch events you get, return FALSE in the method onTouch
• Android will pass on the touch event to your underlying view.
