android - 如何在 kotlin 中将 View 对象转换为我的布局

Question

如何在setAnswer函数中访问page.questionTextView

//Create the given page (indicated by position)
override fun instantiateItem(container: ViewGroup, position: Int): Any {
    val page = inflater.inflate(R.layout.layout_question, null)
    page.questionTextView.text = "hi"

    //Add the page to the front of the queue
    (container as ViewPager).addView(page, 0)
    return page
}

private fun setAnswer(page: View){
    //how to access page.questionTextView
}

Answer 1

我找到了解决方案:我使用“with”方法访问 page.questionTextView

private fun setAnswer(page: View){
    with(page){
        questionTextView.text = "hi"
    }
}
