一、介绍

Pull To Refresh Views for Android

This project aims to provide a reusable Pull to Refresh widget for Android. It was originally based on Johan Nilsson's library (mainly for graphics, strings and animations), but these have been replaced since.

Features

  • Supports both Pulling Down from the top, and Pulling Up from the bottom (or even both).
  • Animated Scrolling for all devices.
  • Over Scroll supports for devices on Android v2.3+.
  • Currently works with:
    • ListView
    • ExpandableListView
    • GridView
    • WebView
    • ScrollView
    • HorizontalScrollView
    • ViewPager
  • Integrated End of List Listener for use of detecting when the user has scrolled to the bottom.
  • Maven Support.
  • Indicators to show the user when a Pull-to-Refresh is available.
  • Support for ListFragment!
  • Lots of Customisation options!

 二、DEMO导入

 

很多人看到有好源码,但是在使用时碰到了问题。在此简单介绍一下,希望能够对那些不会的童鞋们有所帮助。

       首先下载源码,源码地址:https://github.com/chrisbanes/Android-PullToRefresh。
下载完源码之后,解压。在Android-PullToRefresh-master文件夹下,我们会看到还有三个文件夹:extras,
library,sample。其中sample就是作者为我们提供的Demo,library是我们在使用Sample必须用到的jar。extras中是使用ListFragment和ViewPage用到的jar。讲解完目录后现在开始导入了。

       1. 导入library:导入很简单,如图,点击finish即可。

导入之后没有问题。OK! 

     2. 同样导入extras中的PullToRefreshListFragment和PullToRefreshViewPager工程。切记:分别导入。
        如图:

导入之后,你会发现工程报错了,很简单,没有关联libraray。右键工程--选择Properties,打开之后会发现有个红色的X,这就是报错的原因。改了就可以。

选中红色的报错的library,点击Remove,再点击Add,将Libarary添加上即可!如图:

 

 同理将PullToRefreshViewPager工程的library也修改好。

 

3. 导入Sample工程,同时修改library。如图:

 

至此,工程全部导入,错误全部解决。          

运行一下,看是否能够正常运行到手机上。接下来就可以慢慢研究着精品源码吧!

感谢原作者详细的讲解,解决了我的问题!

三、DEMO导入出现问题及解决

一、运行报错:Unable to execute dex: Multiple dex files define Lcom/my/cop/miles/R$anim

 

导致原因:

1、在ADT编译器和SDK的工具有差异或是版本不一致时常会出现

2、引用的两个子项目有相同的包名也会导致这个问题(引用多余的jar包,包出现冲突)

解决方案:

  Eclipse ——> Project ——> 去掉自动构建(Build Automatically)——> 选择project中的clear ——> 选择project中的Build Project ——>启动自动构建(Build Automatically)
