效果图

检索结果

获取检索结果提供了2种方式（具体可参照GitHub源码）
1、 public void getMediaList(int fileModel, Context context)
查找结果放于MediaStoreUtil相应的字段内；
MediaStoreUtil提供了数据改变监听解决办法，通过观察者模式向所有注册了MediaStoreListener的对象发送数据改变结果，
添加数据监听
public static void setListener(MediaStoreListener listener)
移除数据监听
public static void removeListener(int index)
public static void removeListener(MediaStoreListener listener)

2、 public void getMediaList(int searchId, Handler handler)
查找结果交给handler处理
Message message = new Message();
message.what = GetListCallbak.SUCCESS;
message.obj = list;
handler.sendMessage(message);

使用方法：开启服务根据需要调用服务的相应public方法

使用

  //使用UI(直接使用UI中的Fragment)
  public class FilePickerAdapter extends FragmentPagerAdapter {
    private String[] titles = {"image", "video", "audio", "rar", "document", "folder"};
    private ArrayList<Fragment> fragmentlist = new ArrayList<Fragment>();

    public FilePickerAdapter(FragmentManager fm) {
        super(fm);
    }

    public ArrayList<Fragment> getFragmentlist() {
        return fragmentlist;
    }

    @Override
    public Fragment getItem(int position) {
        Fragment fragment = null;
        switch (position) {
            case 0:
                fragment = new ImagePickerFragment();
                break;
            case 1:
                fragment = new VideoPickerFragment();
                break;
            case 2:
                fragment = new AudioPickerFragment();
                break;
            case 3:
                fragment = new RarPickerFragment();
                break;
            case 4:
                fragment = new DocumentPickerFragment();
                break;
            case 5:
                fragment = new FolderPickerFragment();
                break;
            default:
                break;
        }
        fragmentlist.add(fragment);
        return fragment;
    }

    @Override
    public CharSequence getPageTitle(int position) {
        return titles[position];
    }

    @Override
    public int getCount() {
        return titles.length;
    }

  //使用UI时-修改底部功能条
  //在自己的layout文件加下新建
