如何通过intent发送csv文件

Question

这是启动共享意图的函数当Shairing共享框打开时，我可以选择所有选项，如whatsapp，gmail，同时选择这些选项，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，请帮助我解决此

Answer 1

将以下代码添加到清单中的意向过滤器中。

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

并将MIME类型更改为text/plain、text/csv或text/comma-separated-values。

Answer 2

尝试使用

intent.setType("text/*");

请确保在测试设备上安装了足够的应用程序。("text/csv")是正确的格式，但您可以尝试使用("text/plain")，它也会打开安装的所有文本编辑器。
