How to add icon in the circular image view

Question

I have two circular image view, one is containing the profile pic and other is for the camera. Following is my XML file:

1. Welocome.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:background="@drawable/bg"
    android:orientation="vertical"
    tools:context=".activity.WelcomeActivity">

    <TextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_gravity="center"
        android:layout_marginTop="@dimen/margin40"
        android:text="Welcome to Almachat"
        android:textColor="#ffffff"
        android:textSize="25dp" />

    <FrameLayout
        android:layout_width="220dp"
        android:layout_height="220dp"
        android:layout_gravity="center"
        android:layout_marginTop="@dimen/margin10">

        <com.almabay.almachat.circularImageView.CircularImageView
            android:id="@+id/profilePic"
            android:layout_width="170dp"
            android:layout_height="170dp"
            android:layout_gravity="bottom|center_horizontal" />

        <com.almabay.almachat.circularImageView.CircularImageView
            android:id="@+id/iv_camera"
            android:layout_width="80dp"
            android:layout_height="80dp"
            android:layout_gravity="top|right"
            android:layout_marginTop="@dimen/margin30"
            android:background="@drawable/color"
            />
    </FrameLayout>

    <TextView
        android:id="@+id/txtName"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_gravity="center"
        android:layout_marginTop="@dimen/margin20"
        android:textColor="#ffffff"
        android:textSize="30sp"
        android:textStyle="bold" />

    <TextView
        android:id="@+id/txtSomeText"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_gravity="center"
        android:text="Some static text will be here"
        android:textColor="#ffffff"
        android:textSize="20sp" />

    <Button
        android:id="@+id/btnContinue"
        android:layout_width="150dp"
        android:layout_height="wrap_content"
        android:layout_gravity="center"
        android:layout_marginTop="@dimen/margin20"
        android:background="#F7AE21"
        android:padding="@dimen/padding20"
        android:text="Continue"
        android:textColor="#ffffff" />
</LinearLayout>

2.color.xml

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
    android:shape="oval" >
    <gradient
        android:angle="270"
        android:endColor="#F7AE21"
        android:startColor="#F7AE21" />
    <stroke
        android:width="10dp"
        android:color="#F7AE21" ></stroke>
</shape>

This is giving me the following design:

I want to add a camera icon like the following image:

CircularImageView.java

public class CircularImageView extends ImageView {

    public CircularImageView(Context ctx, AttributeSet attrs) {
        super(ctx, attrs);
    }

    @Override
    protected void onDraw(Canvas canvas) {

        Drawable drawable = getDrawable();

        if (drawable == null) {
            return;
        }

        if (getWidth() == 0 || getHeight() == 0) {
            return;
        }

        Bitmap b = ((BitmapDrawable) drawable).getBitmap();
        Bitmap bitmap = b.copy(Bitmap.Config.ARGB_8888, true);

        int w = getWidth(), h = getHeight();

        Bitmap roundBitmap = getRoundedCroppedBitmap(bitmap, w);
        canvas.drawBitmap(roundBitmap, 0, 0, null);
    }

    public static Bitmap getRoundedCroppedBitmap(Bitmap bitmap, int radius) {
        Bitmap
                finalBitmap;
        if (bitmap.getWidth() != radius || bitmap.getHeight() != radius)
            finalBitmap = Bitmap.createScaledBitmap(bitmap, radius, radius,
                    false);
        else
            finalBitmap = bitmap;
        Bitmap output = Bitmap.createBitmap(finalBitmap.getWidth(),
                finalBitmap.getHeight(), Bitmap.Config.ARGB_8888);
        Canvas canvas = new Canvas(output);

        final Paint paint = new Paint();
        final Rect rect = new Rect(0, 0, finalBitmap.getWidth(),
                finalBitmap.getHeight());

        paint.setAntiAlias(true);
        paint.setFilterBitmap(true);
        paint.setDither(true);
        canvas.drawARGB(0, 0, 0, 0);
        paint.setColor(Color.parseColor("#BAB399"));
        canvas.drawCircle(finalBitmap.getWidth() / 2 + 0.7f,
                finalBitmap.getHeight() / 2 + 0.7f,
                finalBitmap.getWidth() / 2 + 0.1f, paint);
        paint.setXfermode(new PorterDuffXfermode(PorterDuff.Mode.SRC_IN));
        canvas.drawBitmap(finalBitmap, rect, rect, paint);

        return output;
    }
}

How can I add a camera icon inside the circular image view? If I am setting the camera icon in the background, only the camera icon is displayed. No circular image view is there.

After using the following code :

<com.almabay.almachat.circularImageView.CircularImageView
    android:id="@+id/iv_camera"
    android:layout_width="80dp"
    android:layout_height="80dp"
    android:layout_gravity="top|right"
    android:layout_marginTop="@dimen/margin30"
    android:background="@drawable/color"
    android:src="@drawable/camera" />

I am getting the following screen:

How can I set the image size to accommodate inside CircularImageView.

            android:layout_width="150dp"
            android:layout_height="150dp"
            android:layout_gravity="center"
            android:layout_marginTop="@dimen/padding_48"
            app:layout_constraintEnd_toEndOf="parent"
            app:layout_constraintStart_toStartOf="parent"
            app:layout_constraintTop_toTopOf="parent">

            <androidx.appcompat.widget.AppCompatImageView
                android:id="@+id/profilePic"
                android:layout_width="match_parent"
                android:layout_height="match_parent"
                android:layout_gravity="bottom|center_horizontal"
                app:srcCompat="@drawable/ic_profile" />

            <androidx.appcompat.widget.AppCompatImageView
                android:id="@+id/iv_camera"
                android:layout_width="40dp"
                android:layout_height="40dp"
                android:layout_gravity="bottom|right"
                app:srcCompat="@drawable/add_profile"
                />
        </FrameLayout>

add_profile

<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
    <item>
        <shape android:shape="oval">
            <solid android:color="@color/rosy_pink"/>
        </shape>
    </item>
    <item
        android:drawable="@drawable/ic_item_select_plus_add"
        android:bottom="@dimen/padding_12"

        android:right="@dimen/padding_12"
        android:top="@dimen/padding_12"/>
</layer-list>


           `android:layout_gravity="bottom|right"`

result :
