I'm trying to use the android support recyclerView widget, and though I've added all the dependencies to my build.gradle file (I think), the line "import android.support.v7.widget.RecyclerView;" in my activity isn't resolving. I'm new to Android Studio, so I might be missing something very basic.
So far I've tried adding the google repository in allprojects of the project build gradle, as well as that of my module build gradle. I've also shifted around my dependencies and tried changing version numbers. And I tried invalidating caches and restarting. I do seem to be able to import "import androidx.recyclerview.widget.RecyclerView;", but that isn't the same from what I've heard.
This is my build gradle file:
//noinspection GradleCompatible
apply plugin: 'com.android.application'
android
compileSdkVersion 28
buildToolsVersion '28.0.3'
defaultConfig
applicationId "com.example.chaos"
minSdkVersion 20
targetSdkVersion 28
versionCode 1
versionName "1.0"
testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"
buildTypes
customDebugType
debuggable true
release
minifyEnabled false

//implementation 'com.android.support:recyclerview-v7:28.0.0'
implementation 'android.arch.persistence.room:runtime:1.1.1'

androidTestImplementation ('androidx.test.espresso:espresso-core:3.2.0-alpha02',
exclude group: 'com.android.support', module: 'support-annotations'
)
And then this is the import I'm attempting in my main activity. It seems I can import android.support.v4 libraries, but v7 isn't even an auto-complete option. I'd appreciate the help!
import android.support.v7.app.AppCompatActivity;
import android.support.v7.widget.RecyclerView;
I expect the import line to resolve, as it currently doesn't.

When creating the project you can uncheck AndroidX option. However, i do not recommend doing that. The old support libraries will no longer be updated. Only AndroidX from now on.
