Android错误（使用对话框时无法从可绘制资源中找到ColorStateList）

【Android错误（使用对话框时无法从可绘制资源中找到ColorStateList）】黄沙百战穿金甲，不破楼兰终不还。这篇文章主要讲述Android错误：使用对话框时无法从可绘制资源中找到ColorStateList相关的知识，希望能为你提供帮助。
我正在尝试对新的android材料库进行测试，但经过数小时的调查后，我无法弄清楚如何解决这个问题。
当我尝试打开任何类型的对话框时发生错误。
这是错误

android.content.res.Resources $ NotFoundException：无法在android.content.res.Resources.loadColorStateList（android.content.res.Resources.loadColorStateList）的android.content.res.ResourcesImpl.loadColorStateList（ResourcesImpl.java:1042）中找到可绘制资源ID＃0x7f070018的ColorStateList .java：1041）在com.android.internal.policy的com.android.internal.policy.PhoneWindow.generateLayout（PhoneWindow.java:2436）的android.content.res.TypedArray.getColor（TypedArray.java:469）。 PhoneWindow.installDecor（PhoneWindow.java:2672）at com.android.internal.policy.PhoneWindow.setContentView（PhoneWindow.java:410）at com.android.internal.app.AlertController.installContent（AlertController.java:263）at android Android.app.Dialog.show上的android.app.Dialog.dispatchOnCreate（Dialog.java:407）中的.app.AlertDialog.onCreate（AlertDialog.java:436）（Dialog.java:302）

ID为＃0x7f070018的资源解析为abc_dialog_material_background，它是appcompat库的一部分。
这是调用错误的代码

val c = Calendar.getInstance() val year = c.get(Calendar.YEAR) val month = c.get(Calendar.MONTH) val day = c.get(Calendar.DAY_OF_MONTH)DatePickerDialog(requireContext(), DatePickerDialog.OnDateSetListener { _, y, m, dayOfMonth -> println(y) println(m) println(dayOfMonth) }, year, month, day).show()

这是我的模块build.gradle文件

所有版本都从项目build.gradle中检索并且是最新的。
答案在一个新项目中一步一步地再做一切后发现问题，它是应用程序主题中的一个项目。
