问Android打开通过ACTION_CREATE_DOCUMENT获得的uri目录。

EN

private void getSaveLocation() {
    Intent intent = new Intent(Intent.ACTION_CREATE_DOCUMENT);
    intent.addCategory(Intent.CATEGORY_OPENABLE);
    intent.setType("application/pdf");
    intent.putExtra(Intent.EXTRA_TITLE, "MyFile.pdf");
    startActivityForResult(intent, MY_CODE);
}

public void onActivityResult(int requestCode, int resultCode, Intent data) {
    if (resultCode != Activity.RESULT_OK || data == null || data.getData() == null) return;

    Uri uri = data.getData();
    OutputStream out = getContext().getContentResolver().openOutputStream(uri);
    // write the pdf to out

    try {
        out.close();
        showSnackbar(uri);
    } catch (IOException e) {
        e.printStackTrace();
    }
}

void showSnackbar(Uri uri) {
    Snackbar snackbar = Snackbar.make(getView(), "Saved to MyFile.pdf", Snackbar.LENGTH_LONG);
    snackbar.setAction("Locate file", new View.OnClickListener() {
        @Override
        public void onClick(View view) {
            Intent intent = new Intent(Intent.ACTION_GET_CONTENT);
            // NEED TO SETUP THE INTENT CORRECTLY USING uri
            activity.startActivity(intent);
        }
    });
    snackbar.show();
}
