It's work only on Android 5.0 and after. Before 5.0 we get a crash during inflate :

Caused by: java.lang.NullPointerException
at de.hdodenhof.circleimageview.CircleImageView.setColorFilter(CircleImageView.java:249)
at android.widget.ImageView.setColorFilter(ImageView.java:1111)

at de.hdodenhof.circleimageview.CircleImageView.<init>(CircleImageView.java:84)

(with v2.0.0 release)

After debuging it appear that all mBitmapPaint, mBorderPaint, mFillPaint, mDrawableRect, mBorderRect, mShaderMatrix are null, whereas they are all initialized and not modifiable.

How is this possible ?

+1 Tint isn't applied to images. Tested on Nexus 5, 6.0.1.

The NPE is fixed, thanks to @colinrtwhite.

I'm not gonna make CirlcleImageView extend AppCompatImageView and with that depend on the appcompat library though, as that would needlessly bloat this library.

Good point - I didn't think about the bloat. However, does that mean image tint on pre-Lollipop will not work? Also, when do you plan to make the next release? Thanks.

android:tint won't work but you can achieve a similar result using setColorFilter(). There are no plans for the next release yet, as the only change so far is the non-critical NPE-fix.

Could you release include this fix ?

as above talks, image tint on after-Lollipop should work. However it doesn't work on android-m... tint attribute is included in not only AppCompatImageView but also ImageView. Why is this? Please have an answer.

@jy617lee you misread that, tint is not supported at all.
