Android遍历特定目录下所有文件,包含子目录的, 并删除最新创建的

直接上代码了..

    private boolean deleteLastFromFloder(String path) {        boolean success = false;        try {            ArrayList<File> images = new ArrayList<File>();            getFiles(images, path);            File latestSavedImage = images.get(0);            if (latestSavedImage.exists()) {                for (int i = 1; i < images.size(); i++) {                    File nextFile = images.get(i);                    if (nextFile.lastModified() > latestSavedImage.lastModified()) {                        latestSavedImage = nextFile;                    }                }                Log.e("brady", "images = " + latestSavedImage.getAbsolutePath());                success = latestSavedImage.delete();            }        } catch (Exception e) {            e.printStackTrace();        }        return success;    }    private void getFiles(ArrayList<File> fileList, String path) {        File[] allFiles = new File(path).listFiles();        for (int i = 0; i < allFiles.length; i++) {            File file = allFiles[i];            if (file.isFile()) {                fileList.add(file);            } else if (!file.getAbsolutePath().contains(".thumnail")) {                getFiles(fileList, file.getAbsolutePath());            }        }    }
