Is there a specific View/Widget available for browsing files on the device? Or is there another solution that has become accepted? Searching has yielded very little useful information for me.
回答1:
Unfortunately there's no special View/widget for browsing files. But it's not very difficult to write it yourself. Googling would find number of public sources/intents for file browsing. General idea is simple: just use File.listFiles() and fill appropriate ListView keeping in mind SD card root and phone FS root.
