java - 如何以一种智能的方式（以及超过 100 个项目）创建这个 Android 自定义“复选框”，如选择？

Question

我正在尝试为此布局创建项目选择逻辑。基本上每个项目都充当一个复选框。从理论上讲，选择的想法非常简单，您单击一个项目 - 被选中，再次单击它 - 被取消选择，单击另一个项目 - 新项目被选中，旧项目被取消选中。基本上你不能选择多个。

更重要的是，每次勾选一个项目，圆角矩形背景从白色（不可见）变为蓝色并带有波纹效果（我已经有这个背景资源用XML制作），然后文本颜色也从蓝色变为白色对比背景，并且图标的资源图像更改为白色对应物（在下图中，它不会导致我忘记添加它，但账单图标应该更改为白色 PNG 计数器部分）。

我正在寻找的是具有最少行数的智能代码，可用于 100 多个不同项目的列表。对于这样的选择也是一个更好的 XML 布局。我最初对线性布局中的项目进行了硬编码，我知道这是一种不适用于许多元素的廉价方式。

这是我为此编写的代码，我尝试在列表中添加每个文本和图标（包括它们的 XML ID）并动态更改它们，但我需要一个比我更好的解决方案。

}

同样，即使我也知道代码底部的布尔值非常不专业，我需要更好的选择代码。谢谢你。
