LoadingDrawable is some android animations implement of drawable: a library can be used in the pull-down to refresh, the placeholders of image loading and the time-consuming tasks. This project idea is from the [link] (http://mp.weixin.qq.com/s?__biz=MjM5MDMxOTE5NA==&mid=402703079&idx=2&sn=2fcc6746a866dcc003c68ead9b68e595&scene=2&srcid=0302A7p723KK8E5gSzLKb2ZL&from=timeline&isappinstalled=0#wechat_redirect).<br/>

The following content show a brief overview of LoadingDrawable
10+
11+
* It extends `Drawable` and implement the interface `Animatable`
12+
* it uses strategy mode
13+
* It can be used as the background of View or content of `ImageView`
14+
* It's constructor must be passed a `LoadingRenderer`
15+
* It interact with `LoadingRenderer` by the callback `Callback`
16+
* `LoadingRenderer` is used for measuring and drawing the `LoadingDrawable`. note:
17+
`LoadingRenderer` is the core
18+
* `LoadingRenderer` only can be created by their `Builder`.

Define the `LoadingView` in XML and specify the `LoadingRenderer` style:

If the LoadingView can't meet your requirements, you might need to refer to the LoadingView customize the View you need
70+
Or specify the `LoadingRenderer` style in Java
71+
```java
72+
***LoadingRenderer.Builder builder = new ***LoadingRenderer.Builder(context);

LoadingView.setLoadingRenderer(builder.build());
