Could not resolve "import android.support.v7.widget.GridLayout; " in Android Studio new project

Question

I tried to use GridLayout as

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

But it was crashing my application. Surfing internet for the problem gave solution that i should use

android.support.v7.widget.GridLayout;

instead of android.widget.GridLayout; but while using this i am getting error could not resolve v7.

Searched for this problem and got many solution to update build.gradle file but it also fails by build.

build.gradle file Initially:

// 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
}

After updating:

    // 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
    }
}

please help me in resolving this issue

You must not add dependencies to Project/build.gradle.

You must add them to the Project/app/build.gradle.

You must move these to Project/app/build.gradle, in the dependencies block:

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'
