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());
            }
        }
    }
