Android拍照上传功能示例代码

本文实例讲述了android实现拍照上传功能的方法。分享给大家供大家参考，具体如下：

1、loginwindow.java －－登录窗口

   }
  };
  okbutton.setonclicklistener(loginbtnlistener);
  backbutton.setonclicklistener(loginbtnlistener);
 }
 private void launchfetion() {
  intent i = new intent(this, funcselector.class);
  i.putextra(key_login_name, mserverip.gettext().tostring());
  i.putextra(key_login_passwd, mserverport.gettext().tostring());
  startactivity(i);
 }
 @override
 public boolean onkeydown(int keycode, keyevent msg) {
//  system.out.println("enter onkeydown() in loginwindow!");
//
//  if (null != loginbtnlistener) {
//   view aview = getcurrentfocus();
//   loginbtnlistener.onclick(aview);
//  }
  return false;
 }
 public static string getserverip() {
    return serverip;
  }
  public static string getserverport() {
    return serverport;
  }
 private button okbutton, backbutton;
 private edittext mserverip;
 private edittext mserverport;
 private onclicklistener loginbtnlistener;
 public static final string key_login_name = "login_name";

 public static final string key_login_type = "login_type";
 public static string serverip = "192.168.0.98"; //;
 public static string serverport = "8081";
}

还需要增加bg_logo.jpg、icon.png、photo_upload.png等几个图片。
