1.写一个类实现FileFilter接口

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 |
public class MP3FileFilter implements FileFilter { @Override public boolean accept(File file) { if(file.isDirectory()) return true; else { String name = file.getName(); if(name.endsWith(".mp3") || name.endsWith(".mp4")) return true; else return false; } } } |
2.传一个路径，获取改路径下的所有mp3 and mp4文件

/** * get all the music file in the rootpath. * @param rootPath */ public void getAllFilePath(String rootPath) { File file = new File(rootPath); File[] files = file.listFiles(new MP3FileFilter()); for(int i=0;i<files.length;i++) { if(files[i].isDirectory()) { getAllFilePath(files[i].getPath()); } else { mArrayListMusicPaths.add(files[i].getPath()); mArrayListMusicNames.add(files[i].getName()); System.out.println(files[i].getPath()); } } } |
