For Glide V4

To be honest,the library can’t supply GlideEngine for Glide both v3 and v4 at the same time. (Anyone who have good idea to achieve this. PR is welcomed)

GlideEngine with Glide v3 is default.

So if your project’s glide version is 4.0+ ,then you must realize GlideEngine by yourself. More details could refer with Glide4Engine in the sample.

Themes

官方

There are two built-in themes you can use to start MatisseActivity:

R.style.Matisse_Zhihu (light mode)

R.style.Matisse_Dracula (dark mode)

And Also you can define your own theme as you wish.

自定义

<color name="zhihu_primary">#1E77EB</color>
<color name="zhihu_primary_dark">#1E77EB</color>
...
