加此处代码为解决xutils加载图片
其二:https://github.com/vinc3m1/RoundedImageView
此组件 用于圆角。圆图,但不支持xutils显示
其三:https://github.com/lopspower/CircularImageView
这个同样不支持xutils
在 onDraw 方法中 加入判断即可
else if(this.getDrawable() instanceof AsyncDrawable){
Drawable drawable = this.getDrawable();
image = Bitmap
.createBitmap(
getWidth(),
getHeight(),
drawable.getOpacity() != PixelFormat.OPAQUE ? Bitmap.Config.ARGB_8888
: Bitmap.Config.RGB_565);
Canvas canvas1 = new Canvas(image);
// canvas.setBitmap(bitmap);
drawable.setBounds(0, 0, getWidth(),
getHeight());
drawable.draw(canvas1);
}
其四:https://github.com/hdodenhof/CircleImageView
这个也不错。同样不支持xutils,判断尚不知道如何加
不要问我哪个最好。。我用的 第三个。。还可以。
