Circular Image View in Android without using any external library

To have a circular ImageView with new Material components of Android use ShapeableImageView of package com.google.android.material.imageview.ShapeableImageView.

Property to apply is shapeAppearanceOverlay

Example:

<com.google.android.material.imageview.ShapeableImageView
            android:id="@+id/ivUserPic"
            android:layout_width="@dimen/_75sdp"
            android:layout_height="@dimen/_75sdp"
            android:adjustViewBounds="true"
            app:layout_constraintStart_toStartOf="parent"
            app:layout_constraintTop_toBottomOf="@+id/labelTitle"
            app:shapeAppearanceOverlay="@style/ShapeAppearance.Image.PILL" />

style:

  <style name="ShapeAppearance.Image.PILL" parent="">
    <item name="cornerFamily">rounded</item>
    <item name="cornerSize">50%</item>
</style>

<style name="ShapeAppearance.Image.Top.PILL" parent="">
    <item name="cornerSizeTopLeft">6dp</item>
    <item name="cornerFamilyTopLeft">rounded</item>
    <item name="cornerSizeTopRight">6dp</item>
    <item name="cornerFamilyTopRight">rounded</item>
</style>

UPDATE

Now we can create circular imageView for Android without using any third-party library or custom ImageView

Use ShapeableImageView

OLD ANSWER

you can try this it is working fine in my device

create one RoundedImageView class like this

import android.content.Context;
import android.graphics.Bitmap;
import android.graphics.Bitmap.Config;
import android.graphics.Canvas;
import android.graphics.Color;
import android.graphics.Paint;
import android.graphics.PorterDuff.Mode;
import android.graphics.PorterDuffXfermode;
import android.graphics.Rect;
import android.graphics.drawable.BitmapDrawable;
import android.graphics.drawable.Drawable;
import android.util.AttributeSet;
import android.widget.ImageView;

public class RoundedImageView extends ImageView
{

    public RoundedImageView(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(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(), 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(Mode.SRC_IN));
        canvas.drawBitmap(finalBitmap, rect, rect, paint);

        return output;
    }

}

now in your layout.xml use below code

<com.example.RoundedImageView
    android:layout_width="150dp"
    android:layout_height="150dp"
    app:srcCompat="@drawable/disha" />

The best way to do it if you use Material Design in your app

<com.google.android.material.card.MaterialCardView
            android:layout_width="75dp"
            android:layout_height="75dp"
            app:cardCornerRadius="50dp"
            app:strokeWidth="1dp"
            app:strokeColor="@color/black">
            <ImageView
                android:layout_width="fill_parent"
                android:layout_height="fill_parent"
                android:id="@+id/paymentlogo"
                android:scaleType="fitCenter"
                android:src="@drawable/your_img" />
        </com.google.android.material.card.MaterialCardView>

You can put your ImageView inside CardView and set its corner radius. Simple example

<android.support.v7.widget.CardView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        card_view:cardCornerRadius="25dp"
        card_view:cardPreventCornerOverlap="false">

        <ImageView
            android:layout_width="50dp"
            android:layout_height="50dp"/>
    </android.support.v7.widget.CardView>

Note that the corner radius should be twice shorter than image size.
