kotlin - java.lang.ClassCastException：java.lang.Integer 无法转换为 android.widget.LinearLayout 当我尝试充气时

Question

rerferf我正在尝试在 Kotlin https://www.youtube.com/watch?v=hfoXhiMTc0c中复制本教程， 但是当我制作膨胀部分时出现此错误：

java.lang.ClassCastException：java.lang.Integer 无法转换为 android.widget.LinearLayout

这是我的代码

var bottomSheetDialog = BottomSheetDialog(this, R.style.Theme_Design_BottomSheetDialog) var view: View = LayoutInflater.from(application).inflate(R.layout.recover_password_sheet, R.id.sheet_container as LinearLayout)

custom_bottom_sheet.xml

xmlns:android="http://schemas.android.com/apk/res/android"android:shape="rectangle"> xmlns:android="http://schemas.android.com/apk/res/android" android:shape="rectangle"> <solid android:color="@color/colorWhite"/> <corners android:topLeftRadius="20dp" android:topRightRadius="20dp"/> </shape>

恢复密码表.xml

Answer 1

您的问题在于：

R.id.sheet_container as LinearLayout

在那里，您尝试将整数（代表资源）转换为LinearLayout.

查看LayoutInflater上的文档，找出函数的哪些重载inflate更适合您的需求。
