Android图片爬虫,看妹纸神器项目源码,ListView单张图片查看

Android图片爬虫,看妹纸神器项目源码

刚自学完安卓,国庆7七天花了6天纯手写入门级app,从集成图片爬虫到整个项目结束真是一步一个坑.

整个项目没有用框架,都是手写纯属练手,项目中主要用到的技术不多,主要是 :

1.网络爬虫

2.线性布局

3.ListView

4.imageView

5.Button

6.AlertDialog

7.sd卡运行时权限

8.图片压缩 BitmapFactory.Options

9.动态布局加载 LayoutInflater

10.定时打开新布局 startActivity()

App使用说明:

app内置图片爬虫,用户首次打开app需要在有WiFi的环境中手动加载图片(用户只能加载一次),

APP尽可能每个用户加载的图片是不同的,且用户每次打开时的图片排列顺序是不同的;

图片压缩:

BitmapFactory.Options options = new BitmapFactory.Options();//解析位图的附加条件
options.inJustDecodeBounds = true;//inJustDecodeBounds设为true，不去解析真实的位图，读取头文件获取基本信息
options.inSampleSize = 8;
options.inJustDecodeBounds = false;
Bitmap bitmap = BitmapFactory.decodeFile(fileList.get(i).getAbsolutePath(), options);

主要是在BaseAdapter类中的getView()方法中用了ImageView点击事件获取图片数据,后通过弹出框 AlertDialog进行展示;
