Question

我正在研究求职门户应用程序，我希望以.doc，.docx和.pdf等所有格式上传简历。目前，一次只支持一种文件格式。以下是我所做的：

Intent intent = new Intent();
            intent.setType("application/pdf,application/msword");
            intent.setAction(Intent.ACTION_GET_CONTENT);
            intent.addCategory(Intent.CATEGORY_BROWSABLE);
            startActivityForResult(intent, REQUEST_CODE_DOC);

请帮我怎么做。谢谢提前

Answer 1

试试这个link。基本上你要做的就是读取文件转换为字节，然后在截击请求中覆盖getBody方法。

                    intent.setAction(Intent.ACTION_GET_CONTENT);
                    intent.addCategory(Intent.CATEGORY_BROWSABLE);
                    startActivityForResult(intent, REQUEST_CODE_DOC);
