术语“没有标签视图指向此文本字段”的含义是：警告信息 [英] Meaning of "No label views point to this text field" warning message

问题描述

此警告的含义是什么？

What is the meaning of this warning?

没有标签视图指向带有android：labelFor = @
id / @ id / editText1属性的文本字段

No label views point to this text field with an android:labelFor="@ id/@ id/editText1" attribute

请注意，双id（ @ id / @ id ）是错误消息文本中出现问题 ，并且不能反映XML内容（这是正确的语法）。

Note that the double id (@id/@id) is a problem with the error message text and does not reflect the XML content (which is the correct syntax).

推荐答案

labelFor 是辅助功能选项的属性。您可以将其分配给标签，以便用户在表单上单击textedit字段时，Android可以知道向用户读取的内容（TalkBack）。

The labelFor is an attribute for accessibility options. You assign this to a label so that if, on a form , user clicks a textedit field , android can know what to read (TalkBack) to user.

分配给它似乎无效。为什么在ID中有两个 @id ？使用这样的ID： @ id / editText1

The id you assigned to it doesn't seem to be a valid one. why there are two @id in the id? Use ids like this: @id/editText1
