RoundedImageView ================ A fast ImageView (and Drawable) that supports rounded corners based on the original [example from Romain Guy](http://www.curious-creature.org/2012/12/11/android-recipe-1-image-with-rounded-corners/)  There are many ways to create rounded corners in android, but this is the fastest and best one that I know of because it: * does **not** create a copy of the original bitmap * does **not** use a clipPath which is not hardware accelerated and not anti-aliased. * does **not** use setXfermode to clip the bitmap and draw twice to the canvas. If you know of a better method, let me know and I'll implement it! Also has proper support for: * Borders * All `ScaleType`s * Borders are drawn at view edge, not bitmap edge. * Except on edges where the bitmap is smaller than the view * Borders are **not** scaled up/down with the image (correct width and radius are maintained) * Anti-aliasing * Transparent backgrounds * Hardware acceleration * Support for TransitionDrawables (XML attrs only) Import Library ---- Import Library: `RoundedImageView/library/` Maven ---- Execute this in your workspace: ``` git clone https://github.com/kolipass/RoundedImageView.git cd ./RoundedImageView/ mvn clean install ``` To run example: ```` cd ./example mvn android:deploy android:run ```` Add this dependency: ``` <dependency> <groupId>com.makeramen.rounded</groupId> <artifactId>library</artifactId> <version>0.1</version> <type>apklib</type> </dependency> ``` Use Library ---- Define in xml: ```xml <com.makeramen.rounded.RoundedImageView xmlns:makeramen="http://schemas.android.com/apk/res/com.makeramen.rounded.RoundedImageView" android:id="@+id/imageView1" android:src="@drawable/photo1" android:scaleType="centerCrop" makeramen:corner_radius="30dip" makeramen:border="2dip" makeramen:border_color="#333333" makeramen:round_background="true" /> ``` Or in code: ```java RoundedImageView iv = new RoundedImageView(context); iv.setScaleType(ScaleType.CENTER_CROP); iv.setCornerRadius(10); iv.setBorderWidth(2); iv.setBorderColor(Color.DKGRAY); iv.setRoundedBackground(true); iv.setImageDrawable(drawable); iv.setBackground(backgroundDrawable); ``` Known Issues -------------------------------------- * Does not round images set by `setImageResource(int resId)`. This causes bitmaps to be inflated on the UI thread anyway, so you should use `setImageDrawable` or `BitmapFactory` and `setImageBitmap()` instead. * Programmatically setting attributes with TransitionDrawables not yet supported. * Only tested support for BitmapDrawables and TransitionDrawables (with BitmapDrawables in them). Other types might work but may have unexpected behavior.
