listview 可重用组件 - 架构 - android
我有一个复杂的视图，其中包含根据要求排列的 4 个列表视图。我已经能够实施并使其发挥作用。但这是一项单独的活动，需要在内部（活动内）提供数据。 我想定义一种方式，其中这个复杂的视图就像一个可重用的组件，由其他活动调用，为所有 4 个列表视图提供数据，然后视图显示在屏幕上。
有人可以指导我如何实现此功能吗？
i have a complex view which contains 4 list views arranged as per the requirement. i have been been able to implement and get it working. but this is a sole activity and data needs to supplied internally (within the activity).
i want to define a way where in, this complex view is like a reusable component which is called by other activities that provide data for all 4 list views and then the view shows up in the screen.
could somebody please guide me as to how do i go about achieving this functionality.

您应该在其自己的布局文件中定义列表视图结构。然后，您可以使用所谓的膨胀，它可以让您在运行时将单独的布局文件“注入”到主布局中。看一下：
http://developer.android.com/reference/android/ view/LayoutInflater.html
请注意介绍性注释。 Android 已经在膨胀 XML 资源，即您在 setContentView() 中定义的布局文件，您可以获取膨胀器的当前实例并根据需要使用它，与您自己实例化它相比，可以大大节省内存。
You should define your listview structure in a layout file of its own. Then you can use whats called inflation, which lets you "inject" seperate layout files into your main layout in run-time. Take a look at:
http://developer.android.com/reference/android/view/LayoutInflater.html
Take note at the introductory notes. Android is already inflating an XML resource, namely the layout file you´ve defined in setContentView(), you can grab the current instance of the inflater and use it as you see fit, saving greatly on memory as opposed to instantiating it yourself.
