circular image view attributes not found

Issue

I'm trying to build a circular image view but when I build the project there is an error occurring with some of the attributes:

I don't know how to solve it. Maybe it's a lack of some additional libraries in build.gradle? My layout code is shown below:

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context="pl.educativo.diagonalcutview.MainActivity">

    <RelativeLayout
        android:id="@+id/background"
        android:layout_width="match_parent"
        android:layout_height="300dp"
        android:background="@drawable/activity_background" />

    <LinearLayout
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_below="@id/background"
        android:layout_marginStart="20dp"
        android:layout_marginLeft="20dp"
        android:layout_marginTop="-100dp">

        <ImageView
            android:layout_width="150dp"
            android:layout_height="150dp"
            android:src="@drawable/bebe2"
            android:civ_border="true"
            android:civ_border_color="@color/semiTransparentWhite"
            android:civ_border_width="10dp"
            android:contentDescription="TODO" />

        <LinearLayout
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:orientation="vertical"
            android:layout_marginStart="12dp"
            android:layout_marginEnd="12dp"
            android:layout_marginBottom="24dp"
            android:layout_gravity="bottom">

            <TextView
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:fontFamily="sans-serif-light"
                android:text="@string/bebe_rexha"
                android:textSize="30sp"
                android:textColor="@android:color/black"/>

            <TextView
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:fontFamily="sans-serif-light"
                android:text="musician, singer, songwriter"
                android:textSize="14sp"/>
        </LinearLayout>
    </LinearLayout>

    <android.support.v7.widget.Toolbar
        android:id="@+id/toolbar"
        android:layout_width="match_parent"
        android:layout_height="?android:attr/actionBarSize"
        android:layout_marginTop="24dp"
        app:theme="@style/TransparentBar">

        <TextView
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:fontFamily="sans-serif-light"
            android:gravity="center_vertical"
            android:text="About"
            android:textSize="24sp" />
    </android.support.v7.widget.Toolbar>
</RelativeLayout>

Solution

Use this Library in App level build.gradle file

implementation 'de.hdodenhof:circleimageview:2.1.0'

Its would be used like this

<de.hdodenhof.circleimageview.CircleImageView xmlns:app="http://schemas.android.com/apk/res-auto"
    android:id="@+id/img_user"
    android:layout_width="150sp"
    android:layout_height="150sp"
    android:layout_centerHorizontal="true"
    android:src="@drawable/ic_driver"
    app:civ_border_color="@color/colorWhite"
    app:civ_border_width="2dp"
    app:civ_fill_color="@color/colorWhite20" />

It has many more other attributes you can check them on:
