ScrollView

基于UGUI的动态滚动列表,主要支持以下功能:

  1. 继承自UGUI的SrollRect,支持ScrollRect的所有功能;

  2. 使用对象池来管理列表元素,以实现列表元素的复用;

  3. 支持一行多个元素或一列多个元素;

  4. 可使用不同尺寸的列表元素;

  5. 列表数据变化后动态刷新列表元素;

用法详见工程中附带的示例,场景Scene中的Canvas1及脚本TestScript

ScrollViewEx

当item数量巨大时,可以使用ScrollViewEx

ScrollViewEx继承了ScrollView的所有功能,并进行了针对性的优化,它会对item进行分页,设置适当的页面尺寸可以得到更好的性能表现,详见场景Scene中的Canvas2,及脚本TestLargeAmount.cs

以下是当有50000个item时使用ScrollViewScrollViewEx,并指定页面尺寸30:

当随机地添加、删除数据或随机跳转时二者耗时:

ScrollView

A DynamicScrollView component based on UGUI that has the following features:

  1. Extented from SrollRect(UGUI class), so supports all the functions of ScrollRect;

  2. Scroll items are managed by an object pool so they can be recycled and reused;

  3. More than one items in one row (or column) is supported;

  4. Items can have different sizes;

  5. Items can be updated when scrollview data change;

For more details please run the test case: active Canvas1 in Scene and play or read TestScript.

ScrollViewEx

When there is a large number of items, ScrollViewEx is recommended.

ScrollViewEx inherits all the features of ScrollView and is optimized for handling massive items by pagination. An appropriate pageSize will result in better performance, see Canvas2 in scene Scene and script TestLargeAmount.cs for details.

The following case shows that a ScrollView and a ScrollViewEx are both working with 50000 items and the latter has a pageSize of 30:
