推荐答案

据 文档:

注意:视图不会自动启用剪辑.如果视图没有被其他项目或屏幕裁剪，则需要设置 clip: true 以便很好地裁剪视图外项目.

Note: Views do not enable clip automatically. If the view is not clipped by another item or the screen, it will be necessary to set clip: true in order to have the out of view items clipped nicely.

因此，您遇到的是一种常见行为，您应该 1) 通过其他 Item(例如标题 Rectangle 和页脚 >Rectangle 和 z:infinite 或简单地将 clip 属性设置为 true，即

Hence, what you are experiencing is a common behaviour and you should either 1) clip the view via other Items (e.g. a header Rectangle and a footer Rectangle with z:infinite or simply set the clip property to true, i.e.

ListView{
   //...
   clip:true
   //...
}

剪辑有一些性能劣势，这会极大地影响随着应用程序的增长.因此，应该仔细评估它的使用，尤其是在视图场景之外.

Clipping has some perfomance disavantages which can greatly affect the application as it grows. Hence, its usage, especially outside the views scenario, should be evaluated carefully.
