谁能解释为什么这个android布局不起作用，并且在启动活动后立即使活动崩溃

Question

此代码无法正常工作，并且该应用始终崩溃。每当我运行代码时，它就会显示错误。即使任何人都可以，请帮助我删除此错误。每当我在应用程序中使用TextInputLayout时，也会发生此错误。

Gradle：

apply plugin: 'com.android.application'
apply plugin: 'kotlin-android'
apply plugin: 'kotlin-android-extensions'

android {
    compileSdkVersion 29
    buildToolsVersion "29.0.3"

    defaultConfig {
        applicationId "com.example.weatherapp"
        minSdkVersion 21
        targetSdkVersion 29
        versionCode 1
        versionName "1.0"

        testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"
    }

    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
        }
    }
