IconicsImageView doesn't work in fragment.need some help!
<b>Hi</b>
here is my case :
1.has registered the font in Application
```js
 Iconics.init(getApplicationContext());
 Iconics.registerFont(new GoogleMaterial());
 Iconics.registerFont(new FontAwesome());
```
2.IconicsImageView works in activity xml layout
3.xmlns:app has been declared in xml
```js
 xmlns:app="http://schemas.android.com/apk/res-auto"
```
4.Maybe,there is some different.i use that component in a RecyclerView which is placed at the fragment layout xml.
  Help me to fix this problem. thanks
