问题描述

我正在使用以下代码在文件管理器中获取文件的文件名和路径.但是，它不会返回 Google Drive 文件的路径.知道如何获得实际路径吗?

I am using the following code to get the file name and path of files in the File Manager. However it does not return a path for Google Drive files. Any idea how to obtain the actual path?

我的代码 -

public String getFilePath() {
    if (uri.getScheme().equalsIgnoreCase("file")) {
        return uri.getLastPathSegment();
    }

    cursorLoader.setUri(uri);
    cursorLoader.setProjection(projections);
    Cursor cursor = cursorLoader.loadInBackground();
    int column_index = cursor.getColumnIndexOrThrow(MediaStore.Files.FileColumns.DATA);
    cursor.moveToFirst();
    String realPath = cursor.getString(column_index);
    cursor.close();

    if (realPath == null || realPath.isEmpty()) {
        return null;
    }

return null;
}

推荐答案

你必须使用 URI.通过URI可以getContentResolver.query(theUriThatYouHave, null, null, null, null).现在有了光标，您可以检查列名等.

You have to use the URI. Through the URI you can getContentResolver.query(theUriThatYouHave, null, null, null, null). Now that you have a cursor, you can check column names etc.

对于 Google 驱动器，有一个列名称 _display_name.这将为您提供文件名.

For Google drive there is a column name _display_name. This will give you the file name.

现在您想访问该文件吗?您可以通过 getContentResolver().openInputStream(theUriThatYouHave) 打开 URI 的 InputStream.

Now you want access to the file? You can open an InputStream to the URI via getContentResolver().openInputStream(theUriThatYouHave).
