我可以通过 FocusRequester 设置焦点状态 TextField，但 Button 不能。

        val requester1 = FocusRequester()
       
        TextField(value = text1,
            { newValue ->
                text1 = newValue
            },
            modifier = Modifier
                .focusable(true)
                .focusRequester(requester1)
                .background(focusedColor1)
                .onFocusChanged {
                    focusedColor1 = if (it.isFocused) {
                        text1 = "TextField1 focused"
                        Color.Red
                    } else {
                        text1 = "TextField1 unfocused"
                        Color.Green
                    }
                }

        )

将调用 TextField 的“onFocusChanged”方法。

        val requester3 = FocusRequester()
        Button(
            onClick = {
                requester3.requestFocus()

            },
            modifier = Modifier
                .focusModifier()
                .focusable(true)
                .focusRequester(requester3)
                .onFocusEvent {
                    Toast
                        .makeText(
                            context,
                            "Button onFocusEvent it.isFocused:${it.isFocused}. ${it.name}", …
