这是一个简单的图片加载 demo，只需要一行代码就可以加载图片；
如果你只想加载一张图片，使用ImageViewEx；
如果你想使用圆形的图片，那就使用RoundImageView;
如果你想使用圆角的图片，那就使用RoundImageView，并调用setConer(x,y);方法，设置圆角;
具体使用方法为：
imageviewex.loadImage("http://f.hiphotos.baidu.com/image/pic/item/ae51f3deb48f8c5471a15c2e38292df5e0fe7f45.jpg");This is a simple image loading demo, only one line of code can be loaded image;

If you want to use a circular image, then use RoundImageView;
If you want to use a rounded picture, then use RoundImageView, and calls setConer(x,y); method, set the fillet;
