Android不赞成使用HttpClient怎么办

HttpClient已经被google弃用了， google自己开发了一套比httpclient更好用的框架叫okhttp 简化了 get post请求， 文件上传下载都进行封装， android中建议使用okhttp框架。

安卓通过httpClient登录客户端时，请求地址URL应该是什么呢（跳转过去是action、jsp、还是servlet）？

假如有一个username 和一个 password 那么就要重写这个URL http：//localhost:8080/项目名称/包名/servlet类名？userame="xxx"&password="xxx" 然后在服务端处理数据

android怎么通过httpclient方式获取服务器中的图片并显示到viewfillpper

第1步，在开始菜单中依次单击“管理工具”→DNS菜单项，打开dnsmgmt窗口。

在左窗格中右键单击服务器名称，选择“配置DNS服务器”命令。

第2步，打开“配置DNS服务器向导”对话框，在欢迎对话框中单击“下一步”按钮。

打开“选择配置操作”对话框，在默认情况下适合小型网络使用的“创建正向查找区域”单选框处于选中状态。

保持默认设置并单击“下一步”按钮。

小提示：上述步骤创建的正向查找区域是指将域名解析为IP地址的过程。

即当用户输入某个域名时，借助于该记录可以将域名解析为IP地址，从而实现对服务器的访问。

第3步，打开“主服务器位置”对话框，选中“这台服务器维护该区域”单选框，并单击“下一步”按钮。

安卓httpclient怎么传输大文件

参考 FileEntity fileentity = new FileEntity(file, "text/txt"); //第一参数时文件对象，后一个参数时文件格式 HttpPost httppost = new HttpPost(url); httppost.setEntity(fileentity); 然后HttpClient.execute(httppost); 服务器端就以数据流的形式来接受。

以ASP.NET为例， Request.InputStream就可以得到输入流。

android通过HttpClient在网页中读取图片，保存到手机里面

通过url获取图片流?，将?流转换成bitmap?再将?bitmap存放到手机 ? ?InputStream?bitmapIs?=?HttpUtils.getStreamFromURL(imageURL); ????Bitmap?bitmap?=?BitmapFactory.decodeStream(bitmapIs); ? ????String?path?=?"/mnt/sdcard/image/";??//?这个就是你存放的路径了。

????File?bitmapFile?=?new?File(path); ????FileOutputStream?fos?=?null; ????if?(!bitmapFile.exists())?{ ?????try{ ??????bitmapFile.createNewFile(); ??????fos?=?new?FileOutputStream(bitmapFile); ??????press(Bitmap.CompressFormat.PNG,100,?fos); ?????}catch?(IOException?e)?{ ??????e.printStackTrace(); ?????}finally?{ ??????try?{ ???????if?(fos?!=?null)?{ ????????fos.close(); ???????} ??????}?catch?(IOException?e)?{ ???????e.printStackTrace(); ??????} ?????} ????}
