解决方案/提示如下。你知道吗

• 使用KivyFileChooserListView
• 添加path和filters

代码段

<FileList>:
    BoxLayout:
        size: root.size
        pos: root.pos
        orientation: "vertical"
        FileChooserListView:
            id: filechooser
            path: './'    # 'android/data'
            filters: ['com.*']

FileChooser » path

path

path is a StringProperty and defaults to the current working directory as a unicode string. It specifies the path on the filesystem that this controller should refer to.

Warning

If a unicode path is specified, all the files returned will be in unicode, allowing the display of unicode files and paths. If a bytes path is specified, only files and paths with ascii names will be displayed properly: non-ascii filenames will be displayed and listed with questions marks (?) instead of their unicode characters.

FileChooser » filters

filters

filters specifies the filters to be applied to the files in the directory. filters is a ListProperty and defaults to []. This is equivalent to ‘*’ i.e. nothing is filtered.

The filters are not reset when the path changes. You need to do that yourself if desired.

There are two kinds of filters: patterns and callbacks.

Patterns

e.g. [‘*.png’]. You can use the following patterns:

Pattern Meaning * matches everything ? matches any single character [seq] matches any character in seq [!seq] matches any character not in seq

Callbacks

You can specify a function that will be called for each file. The callback will be passed the folder and file name as the first and second parameters respectively. It should return True to indicate a match and False otherwise.
