Android应用中拍照后获取照片路径并上传的实例分享

activity 中的代码，我只贴出重要的事件部分代码

public void dophoto(view view) 
{ 
  destorybimap(); 
  string state = environment.getexternalstoragestate(); 
  if (state.equals(environment.media_mounted)) { 
    intent intent = new intent("android.media.action.image_capture"); 
    startactivityforresult(intent, 1); 
  } else { 
    toast.maketext(mainactivity.this, "没有sd卡", toast.length_long).show(); 
  } 
} 
 
@override 
protected void onactivityresult(int requestcode, int resultcode, intent data) 
{ 
  uri uri = data.getdata(); 
  if (uri != null) { 
    this.photo = bitmapfactory.decodefile(uri.getpath()); 
  } 
  if (this.photo == null) { 
    bundle bundle = data.getextras(); 
    if (bundle != null) { 
      this.photo = (bitmap) bundle.get("data"); 
    } else { 
      toast.maketext(mainactivity.this, "拍照失败", toast.length_long).show(); 
      return; 
    } 
  } 
 
  fileoutputstream fileoutputstream = null; 
  try { 
    // 获取 sd 卡根目录 
    string savedir = environment.getexternalstoragedirectory() + "/meitian_photos"; 
    // 新建目录 
    file dir = new file(savedir); 
    if (! dir.exists()) dir.mkdir(); 
    // 生成文件名 
    simpledateformat t = new simpledateformat("yyyymmddsssss"); 
    string filename = "mt" + (t.format(new date())) + ".jpg"; 
    // 新建文件 
    file file = new file(savedir, filename); 
    // 打开文件输出流 
    fileoutputstream = new fileoutputstream(file); 
    // 生成图片文件 
    this.photo.compress(bitmap.compressformat.jpeg, 100, fileoutputstream); 
    // 相片的完整路径 
    this.picpath = file.getpath(); 
    imageview imageview = (imageview) findviewbyid(r.id.showphoto); 
    imageview.setimagebitmap(this.photo); 
  } catch (exception e) {

    } 
  } 
}

其中的上传工具类我们下面一起来看：
android 发送http get post 请求以及通过 multipartentitybuilder 上传文件

全部使用新的方式 multipartentitybuilder 来处理了。

    } 
 
    @override

    @override 
    public string onfailed(int statuscode, zhttprequest request) throws exception { 
      return "post 请求失败：statuscode "+ statuscode; 
    } 
  }); 
 
  textview textview = (textview) findviewbyid(r.id.showcontent); 
  string content = "初始内容"; 
  try { 
    if (view.getid() == r.id.doget) { 
      content = get.get("http://www.baidu.com"); 
      content = "get数据：isget: " + (get.isget() ? "yes" : "no") + " =>" + content; 
    } else { 
      content = post.post("http://192.168.1.6/test.php"); 
      content = "post数据：ispost" + (post.ispost() ? "yes" : "no") + " =>" + content; 
    } 
 
  } catch (ioexception e) { 
    content = "io异常：" + e.getmessage(); 
  } catch (exception e) { 
    content = "异常：" + e.getmessage(); 
  } 
  textview.settext(content); 
} 

其中 picpath 为 sd 卡中的图片路径 string 类型，我是直接拍照后进行上传用的

至于服务端我用的 php ，只是简单的输出获取到的数据而已

print_r($_get); 
echo '<br>'. "\n". 'post:<br>'. "\n"; 
//print_r(array_map('urldecode', $_post)); 
print_r($_post); 
echo '<br>'. "\n". 'files:<br>'. "\n"; 
print_r($_files); 
echo '<br>'. "\n". 'cookies:<br>'. "\n"; 
print_r($_cookie);
