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";
}
