任何人都可以帮助我为什么会收到此错误？

另外，请让我知道我需要在这里显示哪些文件，以便你们可以解决这个错误

下面是'build.gradle'文件代码：

buildscript {
    repositories {
        mavenCentral()
    }

    dependencies {
        classpath "com.android.tools.build:gradle:3.0.1"
    }
}

apply plugin: "com.android.application"

android {
    compileSdkVersion 27
    buildToolsVersion "27.0.2"

    defaultConfig {
        applicationId "com.sg.calculator"
        minSdkVersion 14
        targetSdkVersion 27
        versionCode 1
        versionName "1.0"
    }

    sourceSets {
        main {
            manifest.srcFile "AndroidManifest.xml"
            java.srcDirs = ["src"]
            res.srcDirs = ["res"]
        }
    }

    compileOptions {
        sourceCompatibility JavaVersion.VERSION_1_7
        targetCompatibility JavaVersion.VERSION_1_7
    }
}

repositories {
    mavenLocal()
    maven {
        url "https://maven.google.com"
    }
}

dependencies {
    implementation 'com.android.support:appcompat-v7:25.4.0'
    compile 'com.android.support:support-v4:25.4.0'
    compile 'com.android.support:recyclerview-v7:25.4.0'
    compile files('exp4j-0.4.8.jar')
    compile files('nineoldandroids-2.4.0.jar')
}

        android:inputType="text"
        android:focusable="false"
        android:textColor="@color/display_result_text_color" />

</RelativeLayout>

'res / drawable / pad_button_background.xml'文件代码：

<ripple xmlns:
android="http://schemas.android.com/apk/res/android"
android:color="@color/pad_button_ripple_color" />

RippleDrawable - 在API级别21中添加

因此，您需要将该XML文件移动到至少一个res/drawable-v21文件夹。 （如果不存在则生效）
