Answer 1

If I remember correctly, there should be no direct way to change it. If you must implement this kind of thing, you can only save the country by taking a curve:

• Before or after the keyboard pops up (willShow, didShow Notification), get the view of the keyboard, then traverse to find the Search button you want, and then paste a custom button on it, change the color, implement the return function, etc. .

• Overlay a brand new View on the keyboard, customized by you, and you can do whatever you want.

• Use a customized keyboard to do what Sogou input method does

• Some other methods, I don’t know

I have never done this. The above are just some of my thoughts, which do not mean they are correct.

Answer 2

How about using notifications. When you click search, a notification is sent and the color changes.
