Android之应用开发列表项添加进度框进阶（二十六）文档

今日有时间就学习了下在ListView、GridView列表项中清加ProgressBar,小马用最简单的代码实现可以通用的功能,人人都能看懂,哈哈,直接说下,假如你的适配器getView方法回来的View是一个自定义控件的话,有点欠好实现哦,不过可以用两个控件之间Visible、Invisible来切换实现今日的效果,下面的例子是主类、适配器、异步下载类等的都写在一个类里边了,为的是发的博文里一次性看的话方便,假如大家觉得框架不清楚的话依据本身需求自行抽取下,今日的DEMO只是个简单的思路,其它控件列表项中增加进展框大家也可以用如下的方法实现,老规则,先看效果,再看代码(截图有点失真,但无防)

(I learned how to add ProgressBar in ListView and GridView list items when I have time today. Xiaoma uses the simplest code to implement common functions, which everyone can understand. Ha ha, to put it bluntly, if the view returned from your adapter getView method is a user-defined control, it is not easy to implement. However, you can switch between two controls to achieve today's effect. The following examples are the main class, adapter Asynchronous download classes are all written in one class, so that it is convenient to read the blog post at one time. If you feel that the framework is unclear, you can extract it according to your own needs. Today's DEMO is just a simple idea. You can also add progress boxes to other control list items in the following ways. The old rule is to look at the effect first, and then look at the code (the screenshot is a bit distorted, but there is no prevention))
