有没有办法使 EditText 在禁用 focusableInTouchMode 的情况下可聚焦? [英] Is there a way to make EditText focusable with disabled focusableInTouchMode?

问题描述

我有一些 EditText，我想以编程方式控制它们的焦点顺序.但是，默认情况下，EditText 会在触摸时获得焦点，因此这会破坏顺序.

I have some EditTexts, and I want to control their focus order programmatically. However, EditText will get focus when touched by default, so this will break the order.

我曾尝试将 EditText 的 focusableInTouchMode 设为 false，但它从未获得焦点，就像它禁用了可聚焦一样.

I have tried to make EditText's focusableInTouchMode false, but it never got focus then, like it has disabled focusable.

那么，有没有办法禁用它的 focusableInTouchMode 但仍然可以聚焦?

So, there is a way to disable it's focusableInTouchMode but still focusable?

推荐答案

Alan 希望这是不可能的.解决方法是，创建一个 0dp 高和 0dp 宽的假编辑文本.

hope it's impossible Alan.Work around is ,Create one fake editText with 0dp hight and 0dp width.
