CircleImageView

A fast circular ImageView perfect for profile images. This is based on RoundedImageView from Vince Mi which itself is based on techniques recommended by Romain Guy.

It uses a BitmapShader and does not:

• create a copy of the original bitmap
• use a clipPath (which is neither hardware accelerated nor anti-aliased)
• use setXfermode to clip the bitmap (which means drawing twice to the canvas)

As this is just a custom ImageView and not a custom Drawable or a combination of both, it can be used with all kinds of drawables, i.e. a PicassoDrawable fromPicasso or other non-standard drawables (needs some testing though).

Gradle

dependencies {    ...    compile 'de.hdodenhof:circleimageview:2.2.0'}

Usage

<de.hdodenhof.circleimageview.CircleImageView    xmlns:app="http://schemas.android.com/apk/res-auto"    android:id="@+id/profile_image"    android:layout_width="96dp"    android:layout_height="96dp"    android:src="@drawable/profile"    app:civ_border_width="2dp"    app:civ_border_color="#FF000000"/>

Limitations

• The ScaleType is always CENTER_CROP and you'll get an exception if you try to change it. This is (currently) by design as it's perfectly fine for profile images.
• Enabling adjustViewBounds is not supported as this requires an unsupported ScaleType
• If you use an image loading library like Picasso or Glide, you need to disable their fade animations to avoid messed up images. For Picasso use thenoFade() option, for Glide use dontAnimate(). If you want to keep the fadeIn animation, you have to fetch the image into aTarget and apply a custom animation yourself when receiving the Bitmap.
• Using a TransitionDrawable with CircleImageView doesn't work properly and leads to messed up images.
