在Kotlin中的适配器中调用时，如何在AlertDialog.Builder()中设置上下文？

val adapter = ArrayAdapter<String>(this, android.R.layout.simple_list_item_1, dataList)

val builder = AlertDialog.Builder(this)
builder.setAdapter(adapter) { dialog, which ->
    // 处理点击事件
}
builder.show()

val adapter = ArrayAdapter<String>(requireContext(), android.R.layout.simple_list_item_1, dataList)

val builder = AlertDialog.Builder(requireContext())
builder.setAdapter(adapter) { dialog, which ->
    // 处理点击事件
}
builder.show()
