在Android Studio新项目中无法解析“导入android.support.v7.widget.GridLayout;”

我试图将GridLayout用作

GridLayout maingrid=(GridLayout)findViewById(R.id.mainGridView);

但是它使我的应用程序崩溃了。 上网冲浪解决该问题,我应该使用

android.support.v7.widget.GridLayout; 

而不是android.widget.GridLayout;,但是在使用此方法时出现错误无法解决v7。

搜索了此问题,并获得了许多解决方案来更新 build.gradle 文件,但该文件也因构建而失败。

build.gradle文件最初:

// Top-level build file where you can add configuration options common to all sub-projects/modules.

buildscript {
    repositories {
        google()
        jcenter()

    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.4.2'
        implementation 'com.android.support:cardview-v7:21.+'
        implementation 'com.android.support:recyclerview-v7:21.+'
        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }
}

allprojects {
    repositories {
        google()
        jcenter()

    }
}

task clean(type: Delete) {
    delete rootProject.buildDir
}

更新后:

    // Top-level build file where you can add configuration options common to all sub-projects/modules.

buildscript {
    repositories {
        google()
        jcenter()

    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.4.2'
        implementation fileTree(dir: 'libs', include: ['*.jar'])
        implementation 'com.android.support:appcompat-v7:26.1.1'
        implementation 'com.android.support.constraint:constraint-layout:1.0.2'
        implementation 'com.android.support:design:26.1.1'
        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }
}

allprojects {
    repositories {
        google()
        jcenter()

    }
}

task clean(type: Delete) {
    delete rootProject.buildDir
}

android {
    compileSdkVersion 26
    buildToolsVersion "26.0.2"

    defaultConfig {
        minSdkVersion 16
        targetSdkVersion 26
    }
}

请帮助我解决此问题

您不得将依赖项添加到Project / build.gradle。

您必须将它们添加到Project / app / build.gradle。

您必须将它们移动到{/ {1}}块中的Project / app / build.gradle:

dependencies
