选择文本并从标签xamarin表格中复制 [英] Select text and copy from label xamarin forms

问题描述

几天来，我一直在不同的论坛上阅读有关选择文本并从xamarin形式的标签中复制文本的问题，这似乎并不是实现此问题的直接方法.

I have for some days been reading on different forums about the issue of selecting a text and copying the text natively from a label in xamarin forms and it seems to be no straightforward way of implementing this.

我的问题是我需要在标签中呈现一本书中的大量数据，并且用户应该能够从标签中选择并复制大量文本. 我继续将数据显示在编辑器组件中，但随后用户可以在编辑器中编辑文本.将Editor组件设置为只读也不能解决问题.

My problem is that I need to present a large amount of data from a book in a label and the user should be able to select and copy a chunk of text from the label. I moved on to present the data in an Editor component instead but then the user can edit the text in the Editor. Making the Editor component read-only doesn't solve the problem either.

任何建议将不胜感激！

Any suggestions would be greatly appreciated!

推荐答案

我最近遇到了同样的业务需求.在每个平台上带有Renderers定制的Editor是我的解决方案.

I recently faced the same business requirement. An Editor with Renderers customization on each platform was the solution for me.

简而言之，Android renderer利用EditText的CustomSelectionActionModeCallback和CustomInsertionActionModeCallback属性来自定义上下文菜单以进行文本选择和插入，而iOS renderer非常简单明了，并设置了Selectable和Editable UITextView的属性.

In short, Android renderer leverages CustomSelectionActionModeCallback and CustomInsertionActionModeCallback properties of EditText to customize context menu for text selection and insertion, while iOS renderer is pretty straight-forward and sets Selectable and Editable properties of UITextView.
