我在ListFragment中有一个自定义列表视图，有3种类型的标题（1st.Green Background，2nd.Black Background，3rd.Gray background），正如您在video中看到的那样。
我想自定义绿色标题，即点击绿色标题时，必须最小化下一个绿色标题之间的所有视图（项目），＆amp;再次点击那个绿色标题，应该放弃最小化的视图。
像FloatingGroupExpandableListView这样使用一些虚拟物品的功能，在我的情况下，必须自定义视图。
我不知道如何修改我的代码来完成这项任务。

谢谢，请帮忙。 。 。 。 。
答案 0 :(得分：-1)
我没有审核过你的代码，但是这里有一个如何实现它的想法：
显然你无法真正最小化它，因为列表视图只显示部分视图，而实际的最小化视图量可能要大得多。
此外，在最小化了所有需要最小化的视图后，您不能将它们显示为空视图（height = 0），因为您的列表将为空。
因此，为了解决第二个问题，我建议操纵数据以排除这些视图。
第一个问题难以解决，你可能需要妥协一些方法。 您可以最小化所有可见视图，但是整个列表视图可能会变小或者在其中创建一个大厅。在最小化完成后，您将更新数据，并获得应该在繁荣中可见的视图的所有重置。 如果您有1或2个视图可以最小化，这可能会很有效，但通常这不是一个完美的想法。
另一种解决方案是忘记列表视图，实际上在内存中拥有所有视图，我认为这是实现它的唯一方法。
总的来说，这是一项非常艰巨的任务。
