代码对我来说很好。

您确定设备上安装了DocumentsProvider可以处理.docx吗？

你确定你的哑剧模式是正确的吗？ docx的mime是application/vnd.openxmlformats-officedocument.wordprocessingml.document。无论如何，您将其指定为以＆＃34; /＆＃34;开头似乎不正确，因为mime类型是斜线分隔但不以＆＃34; /＆＃34;开头。

找不到处理Intent的活动{act = android.intent.action.OPEN_DOCUMENT cat = [android.intent.category.OPENABLE] typ = / *}
