Android 遍历SDCARD的文件夹并显示目录信息

private String mResult = new String(); private String[] mFileList = null;

1）、显示所有文件/

File flist = new File("/mnt/sdcard"); mFileList = flist.list(); for(String str: mFileList){ mResult += str; mResult += "\n"; }TextView tv = (TextView)findViewById(R.id.result);
tv.setText(mResult.toString());

２）、显示指定后缀名的文件/

FilenameFilter fnf = new FilenameFilter(){ public boolean accept(File dir, String filename) { if(filename.endsWith(".mp3")) return true; return false; } }; mFileList = flist.list(fnf); for(String str: mFileList){ mResult += str; mResult += "\n"; }

3）、仅显示目录/

FileFilter ff = new FileFilter(){ public boolean accept(File pathname) { return pathname.isDirectory(); } };File[] fileDir = flist.listFiles(ff);for (int i = 0; i < fileDir.length; i++) { String str = fileDir[i].getName(); mResult += str; mResult += "\n"; }
