Android自定义控件，旋转头像直接用在你的项目中（酷毙了）

分享一些自定义控件，都是上次搞开发是做的自定义控件可以直接用，若是小伙伴们也需要的话可以用在自己的项目中去，先看看效果吧，不会截gif的图片，我就截了2章图片，看看效果，当然啦，图片上的人就是我女神啦！

可以吧，这效果，不过背景是通过高斯模糊的，小伙伴可自己去看看什么是高斯模糊，
下面就是这个旋转效果的主要控件了

        canvas.drawCircle(defaultWidth / 2, defaultHeight / 2, radius, paint);  
    }  
}

但是他还需要一些配置文件，在res/values/attrs.xml下面

    <declare-styleable name="roundedimageview">
        <attr name="border_thickness" format="dimension" />
        <attr name="border_inside_color" format="color" />
        <attr name="border_outside_color" format="color"></attr>
    </declare-styleable>

以上就是关于这个自定义控件的全部了，如何使用呢？下面就是关于怎么用了
布局文件

 <com.agbc.ui.RoundImageView
                android:id="@+id/charace_photo"           android:layout_width="@dimen/usercenter_photo_width"          android:layout_height="@dimen/usercenter_photo_width"
