Android 由30多个视图组成的自定义视图的缓慢渲染
我有一个自定义视图，其中包含两行，每个行有4个其他自定义视图，并且在这8个自定义视图的每个视图周围都有边框 在xml中，我使用的是Android 由30多个视图组成的自定义视图的缓慢渲染,android,xml,android-constraintlayout,Android,Xml,Android Constraintlayout,我有一个自定义视图，其中包含两行，每个行有4个其他自定义视图，并且在这8个自定义视图的每个视图周围都有边框 在xml中，我使用的是ConstraintLayout，第一行和第二行有两个不可见的视图，这有助于使视图具有相同的宽度-s和高度-s 设计是伟大的工作，但让我烦恼的是，渲染太慢。我尝试删除视图的约束，如果没有约束，它的运行速度似乎更快 我的问题是：有没有办法提高这个视图的性能，或者这是正确的方法 下面是我使用的xml： <?xml version="1.0" encoding="u

优化布局的方法多种多样。首先，嵌套的
ConstraintLayout引导线，而不是使用嵌套约束布局。使用百分比值25%、50%、75%并将所有视图约束到约束。您的自定义视图将是屏幕的1/4，app:layout\u constraintDimensionRatio=“1:1”
将具有相同的高度
最后，您将有3个指南行
和4个自定义视图，这将更快、更简单布局我通过应用3个垂直指南
并删除应用程序：布局约束尺寸比=“1:1”修复了性能问题
用于表格中的8项，因为此时不需要 您是否尝试过使用简单的GridView而不是ConstraintLayout？您是否在层次结构查看器
@TodorKostov中查看了布局？我忘了提到这一点，但我需要控制每个项目的边界。如我提供的图像所示，我希望在启用/禁用项目时能够更改边框的颜色。我能用GridView
复制这种行为吗？我相信这是可能的。您仍然有自定义视图，但将只有一个GridView，而不是2个ConstraintLayouts。这将降低总体布局的复杂性。
