一个强大的android view looper 库，以简化日常开发这种高频率的功能。支持安卓2.2及更高版本。
Background
Image loop banner is high frequency used in most apps. So is the app of the company I work for. At first, this is only used in home page. Later with the app update, there are some simliar functions needed in other pages both image and text. I copy the same code here and there, finally I can not standing copying anymore. I explore on the github to find libs that meet my needs. Though I find some poewful libs, but the lib what I want should support view looping not only ImageView. And I do not want a lib having a ImageLoad Framework inside. So I decide to code a libray with features below:
- Use Executors instead of Task
- Supports both normal banner and endless auto loop banner
- Supports inflate item view and logic operation such as loading image outside.
- Supports set source using data list with different entity
- Supports smartly pause scroll and continue scroll.
- Touch down pause. Touch up continue.
- Window of activty off pause.Window of activty on continue.
- Supports inner indictaors
- Supports page transformer (not often used in my daily work, just support this feature for others if needed)
