[英]how to resolve findviewbyid in kotlin?
I tried almost everything but it doesn't seem to work, I keep getting a cannot resolve findviewById for the buttons at the bottom.我几乎尝试了所有方法,但它似乎不起作用,我不断收到无法解析底部按钮的 findviewById。 the button declarations have the same errors but I have fixed those correctly, the bottom buttons don't seem to behave the same way.
按钮声明具有相同的错误,但我已正确修复这些错误,底部按钮的行为似乎不同。 I'm new to android, please help!
我是 android 的新手,请帮忙!
add requireActivity()
before findViewById.在 findViewById 之前添加
requireActivity()
。 for example:例如:
btn = requireActivity().findViewById<Button>(R.id.btn)
