Android 如何通过intent发送csv文件

这是启动共享意图的函数 当打开共享框时，我可以选择所有选项，如whatsapp、gmail，而选择这些选项时，文件不会被附加

private void OpenShare(String filename) {


        Uri uri = Uri.parse(( getExternalFilesDir(Environment.DIRECTORY_DOWNLOADS).getPath()+filename));


        Intent sharingIntent = new Intent();
        sharingIntent.setAction(Intent.ACTION_SEND);
        sharingIntent.setDataAndType(uri, "text/*");
        startActivity(Intent.createChooser(sharingIntent, "share file with"));



    }

共享框正在打开，请帮我解决这个问题

 <data android:mimeType="text/comma_separated_values/csv" />



并将MIME类型更改为
text/plain
，
text/csv
或
text/comma分隔值

intent.setType("text/*");

确保测试设备上安装了足够的应用程序。
（“text/csv”）
是正确的格式，但是您可以尝试使用
（“text/plain”）
，这将打开所有安装的文本编辑器。
