突然，我的 TextInputEditText 的绑定开始失败，这与链接器有关。如果我将链接器设置为“无”，则一切都会按预期进行。我使用的许多其他绑定仍然可以正常工作。
我得到的堆栈：

我已经将以下内容添加到“请包含链接”中，但没有帮助。
public void Include(TextInputEditText text)
{
text.TextChanged += (sender, args) => text.Text = "" + text.Text;
text.Hint = "" + text.Hint;
text.Background = (Drawable)Android.Resource.Color.Black;
text.Text = "Text" + text.Text;
}
public void Include(TextInputLayout text)
{
text.Hint = "" + text.Hint;
text.Background = (Drawable)Android.Resource.Color.Black;
}
将 TextInputEditText 更改为简单的 EditText 也没有帮助，并且会引发相同的异常。
我缺少什么？通过查看堆栈，我并没有更接近解决方案。
经过一番挖掘后我发现了这个answer https://stackoverflow.com/a/40433275/2026877这表明 MvvmCross 的新版本 (v4.4.0) 发生了变化，需要对项目的 LinkerPleaseInclude.cs 中的 TextView 部分进行调整
