I have searched more on websites and got many suggestions like below
Changing background with custom style to set the corner radius and padding ( Getting image as rectangle and background as rounded corner)
Changing Given image to Bitmap by decoding the image and cropping functionality by passing this bitmap and width ( its taking more time to load)
I have checked the WhatsApp Chat history list and it has rounded corner images but its loaded with minimum time.
Could you please suggest me the best way to create listview template with rounded images as in WhatsApp?
I am expecting to change the image with rounded corner by setting the style details in xml page. (image width and height is 60 dp, also my listview having around 60 items)
References :
res/mylayout.xml:
<ImageView
android:id="@+id/contactssnap"
android:layout_width="50dp"
android:layout_height="50dp"
android:src="@drawable/contactssnap"
android:background="@drawable/roundimage" />
res/drawable/roundimage.xml:
<?xml version="1.0" encoding="UTF-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle" >
<solid android:color="#ffffffff" />
<stroke
android:width="2dp"
android:color="#90a4ae" />
<size
android:height="50dp"
android:width="50dp" />
<padding
android:bottom="2dp"
android:left="2dp"
android:right="2dp"
android:top="2dp" />
<corners android:radius="100dp" />
</shape>
Note: Supported Android Version from 14 to 22

If you MUST use background to set your image instead of src, you can use this workaround: Create a layout and set its background to your shape drawable. Wrap that layout around your ImageView (with no padding) The ImageView (including anything else in the layout) will now display with rounded layout shape.
In the upper left corner, select “Draw Filled Shape“. Draw the rounded rectangle over the area you would like to keep for your rounded corners image. Use the Magic Wand to select the area of the rounded rectangle.
Simply put a circular_crop. png in your drawable folder which is in the shape of your image dimensions (a square in my case) with a white background and a transparent circle in the center. You can use this image if you have want a square imageview. Just download the picture above.
The Material Components Library provides the new ShapeableImageView.
Just use a layout like:
<com.google.android.material.imageview.ShapeableImageView
...
app:shapeAppearanceOverlay="@style/roundedCorners"
app:srcCompat="@drawable/...." />
With the shapeAppearanceOverlay attribute you can apply a custom shape, in this case rounded corners:
<style name="roundedCorners" parent="">
<item name="cornerFamily">rounded</item>
<item name="cornerSize">xxdp</item>
</style>
*Note: it requires at least the version 1.2.0-alpha03.

The answer from sats is worked. But RoundedBitmapDrawable cannot be applied to an ImageView with scaleType: centerCrop.
An updated.
If you are using Android API at level 21. We have a simple solution here.
1st, create drawable as background for the imageview
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle">
<corners android:radius="8dp" />
<solid android:color="@android:color/white" />
<stroke
android:width="1dp"
android:color="@color/colorWhite" />
</shape>
Next, change ImageView's property setClipToOutline to true. And set rounded drawable as ImageView's background.
That's it.
In my demo, I using this method for rounded imageview. Can find it here cuberto's dialog
