Android:从web下载图像并在gridview上显示 [英] Android: Download images from web and show them on gridview
问题描述
我想创建一个程序,从网页获取一些图像,并在gridview中显示它们。我不知道他们有多少。它可能是从20到30.不好用asynctask,我以前已经使用过,或多或少知道它是如何工作的。但是我不知道这一次使用它。
I want to create a program that gets some images from a webpage, and shows them on a gridview. I dont know how many of them exactly. It could be from 20 to 30. Ill do it with asynctask, which i have allready used before and more or less know how it works. But i don't know which way use it this time.
现在,我想要得到的是一个进度条(圆点击),而图像正在下载。一旦下载,它将消失,图像将加载。我将使用一个带有适配器的对象数组来填充gridview。
For now, what i would like to get is a progressbar (circle clicking) while image is downloading. And once its downloaded, it would disappear and image will load. I will use an array of objects with an adapter, to fill the gridview.
你会使用asynctask吗?
Which way would you use the asynctask?
提前感谢
