Full Sampleįor a full sample see the DraweeRoundedCornersFragment in the showcase app: DraweeRoundedCornersFragment.Pro tip: Round corners on an Android ImageView with this hackĪndroid ImageViews by default don't have an option to set a corner radius.

Furthermore, canvas clipping doesn’t support antialiasing which makes the rounded edges very pixelated.įinally, all of those issues could be avoided by using a temporary bitmap, but this imposes a significant memory overhead and has not been supported because of that.Īs explained above, there is no really good solution for rounding corners on Android and one has to choose between the aforementioned trade-offs. The OVERLAY_COLOR mode doesn’t have the aforementioned limitations, but since it simulates rounded corners by overlaying a solid color over the image, this only looks good if the background under the view is static and of the same color.ĭrawee internally has an implementation for CLIPPING mode, but this mode has been disabled and not exposed as some Canvas implementation do not support path clipping. If the limitations of the BITMAP_ONLY mode affect your images, see if the OVERLAY_COLOR mode works for you. This is the best solution for PNG resource images. Another workaround is to make the image file contain a 1px transparent border so that the transparent pixels get repeated. centerCrop) that ensures that the whole view is covered. One workaround is to use a different scale type (e.g.

Due to a limitation of Android’s BitmapShader, if the image doesn’t fully cover the view, instead of drawing nothing, edges are repeated.

Rounding NinePatchDrawable, ShapeDrawable and other such drawables is not supported (regardless whether they are specified in XML or programmatically).

Only images that resolve to BitmapDrawable or ColorDrawable can be rounded.

There are some limitations when BITMAP_ONLY (the default) mode is used: setRoundAsCircle ( true ) mSimpleDraweeView. setBorder ( color, 1.0f ) roundingParams. fromCornersRadius ( 5 f ) roundingParams. red ) RoundingParams roundingParams = RoundingParams. The SimpleDraweeView class will forward several attributes over to RoundingParams:

Use roundWithOverla圜olor in XML, or setOverla圜olor in code to use this rounding method. The Drawee’s background should be static and of the same solid color. OVERLAY_COLOR - Draws rounded corners by overlaying a solid color, specified by the caller.repeated edges due to how Android shaders work), especially in cases the source image is smaller than the view. If you use this rounding method with other scale types, such as center, you won’t get an Exception but the image might look wrong (e.g. It doesn’t support animations, and it does not support any scale types other than centerCrop (the default), focusCrop and fit_xy. BITMAP_ONLY - Uses a bitmap shader to draw the bitmap with rounded corners.Images can be rounded with two different methods:

Rectangles support having each of the four corners have a different radius, but this must be specified in Java code rather than XML. As a rectangle, but with rounded corners.As a circle - set roundAsCircle to true.

Drawee supports a variety of scenarios, all without the memory overhead of copying bitmaps. Apps frequently need images that appear with softer, rounded corners, or as circles.
