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) {
    e.printstacktrace();
  } finally {
    if (fileoutputstream != null) {
      try {
        fileoutputstream.close();
      } catch (exception e) {
        e.printstacktrace();
      }
    }
  }
}

/**
 * 销毁图片文件
 */
private void destorybimap()
{
  if (photo != null && ! photo.isrecycled()) {
    photo.recycle();
    photo = null;
  }
}

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

  zhttprequest post = new zhttprequest();

      .setcharset(http.utf_8)
      .setconnectiontimeout(5000)
      .setsotimeout(10000);
  post.setonhttprequestlistener(new zhttprequest.onhttprequestlistener() {
    private string charset = http.utf_8;
    private contenttype text_plain = contenttype.create("text/plain", charset.forname(charset));

    @override
    public void onrequest(zhttprequest request) throws exception {
      // 设置发送请求的 header 信息
      request.addheader("cookie", "abc=123;456=爱就是幸福;");
      // 配置要 post 的数据
      multipartentitybuilder builder = request.getmultipartentitybuilder();
      builder.addtextbody("p1", "abc");
      builder.addtextbody("p2", "中文", text_plain);
      builder.addtextbody("p3", "abc中文cba", text_plain);
      if (picpath != null && ! "".equals(picpath)) {
        builder.addtextbody("pic", picpath);
        builder.addbinarybody("file", new file(picpath));
      }
      request.buildpostentity();
    }

    @override
    public string onsucceed(int statuscode, zhttprequest request) throws exception {
      return request.getinputstream();
    }

    @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

<?php
echo 'get:<br>'. "\n";
//print_r(array_map('urldecode', $_get));
print_r($_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);
