Fresco添加缩放支持

---

1. 添加gradle依赖

compile('com.facebook.fresco:fresco:1.0.0') {

excludemodule:'support-v4',group:'com.android.support'

}

// 配置fresco使用okhttp3发起网络请求

compile('com.facebook.fresco:imagepipeline-okhttp3:1.0.0') {

excludemodule:'okhttp',group:'com.squareup.okhttp3'

}

// 实现缩放效果

compile'com.autonavi.gxdtaojin:lib-cview-photodraweeview:1.0.0'

2. 用PhotoDraweeView替换fresco默认的SimpleDraweeView

mPhotoDraweeView.setPhotoUri(Uri.parse("http://your.image.url"));
