    MultipartEntity mpEntity = new MultipartEntity();
  
    mpEntity.addPart("fileToUpload", cbFile);

       //  mpEntity.addPart("字符串参数", new StringBody("user"));


    httppost.setEntity(mpEntity);

    con.setUseCaches(false);

    con.setRequestMethod("POST");

    con.setRequestProperty("Connection", "Keep-Alive");
    con.setRequestProperty("Charset", "UTF-8");
    con.setRequestProperty("Content-Type",
            "multipart/form-data;boundary=" + boundary);

    DataOutputStream ds = new DataOutputStream(con.getOutputStream());
    ds.writeBytes(twoHyphens + boundary + end);
    ds.writeBytes("Content-Disposition: form-data; "
            + "name=\"file1\";filename=\"" + newName + "\"" + end);
    ds.writeBytes(end);

    FileInputStream fStream = new FileInputStream(uploadFile);

    int bufferSize = 1024;
    byte[] buffer = new byte[bufferSize];

    int length = -1;

    fStream.close();
    ds.flush();

    InputStream is = con.getInputStream();
    int ch;
    StringBuffer b = new StringBuffer();
    while ((ch = is.read()) != -1) {
        b.append((char) ch);
    }

    showDialog("上传成功" + b.toString().trim());

  }
}

用到的dialog对话框，用来显示测试结果：

[html]    private void showDialog(String mess) {
w AlertDialog.Builder(TestuploadImageActivity.this)
.setTitle("Message").setMessage(mess)
.setNegativeButton("确定", new Dialoginterface.OnClickListener() {
    public void onClick(DialogInterface dialog, int which) {
    }
}).show();
