PictureSelector图片选择器封装，只需两句就可以实现初始化获取结果

public class PictureSelectorView {

    private static PictureSelectorView selectView = null;
    private PictureParameterStyle mStyle;
    private int mSelectNum = 8;//最多选择图片
    private int mSpanNum = 4;//每行显示多少图片
    private Activity mActivity;
    private Context mContext;
    private RecyclerView mRecyclerView;
    private GridImageAdapter mAdapter;
    private static List<MultipartBody.Part> mPartBodyList = new ArrayList<>();
    private static List<LocalMedia> mLocalMediaList = new ArrayList<>();
    private static List<String> mLocalMediaPathList = new ArrayList<>();

    public static PictureSelectorView getInstance() {
        if (selectView == null) {
            synchronized (PictureSelectorView.class) {
                if (selectView == null) {
                    selectView = new PictureSelectorView();
                }
            }
        }
        return selectView;
    }
