如何在Android列出目录中的文件？ [英] How to list files in an android directory?

问题描述

下面是我的code到目前为止：

Here's my code so far:

String path = Environment.getExternalStorageDirectory().toString()+"/Pictures";

        AssetManager mgr = getAssets();

        try {

            String list[] = mgr.list(path);
            Log.e("FILES", String.valueOf(list.length));

            if (list != null)
                for (int i=0; i<list.length; ++i)
                    {
                        Log.e("FILE:", path +"/"+ list[i]);
                    }

        } catch (IOException e) {
            Log.v("List error:", "can't list" + path);
        }

不过，虽然我有在目录文件，它返回我list.length = 0 ...任何想法？

Yet while I do have files in that dir, it returns me list.length = 0... any ideas?

谢谢！

推荐答案

试试这个：

String path = Environment.getExternalStorageDirectory().toString()+"/Pictures";
Log.d("Files", "Path: " + path);
File f = new File(path);        
File file[] = f.listFiles();
Log.d("Files", "Size: "+ file.length);
for (int i=0; i < file.length; i++)
{
    Log.d("Files", "FileName:" + file[i].getName());
}
