Demo 下载之后把 pickerview 作为 Module 引入到项目中,

添加工具类：

public class Util {

    /**
     * 时间选择回调
     */
    public interface TimerPickerCallBack {
        void onTimeSelect(String date);
    }

    /**
     * 弹出时间选择
     *
     * @param context
     * @param type     TimerPickerView 中定义的 选择时间类型
     * @param format   时间格式化
     * @param callBack 时间选择回调
     */
    public static void alertTimerPicker(Context context, TimePickerView.Type type, final String format, final TimerPickerCallBack callBack) {
        TimePickerView pvTime = new TimePickerView(context, type);
        //控制时间范围
        //        Calendar calendar = Calendar.getInstance();
        //        pvTime.setRange(calendar.get(Calendar.YEAR) - 20, calendar.get(Calendar.YEAR));
        pvTime.setTime(new Date());
        pvTime.setCyclic(false);
        pvTime.setCancelable(true);
        //时间选择后回调
        pvTime.setOnTimeSelectListener(new TimePickerView.OnTimeSelectListener() {

            @Override
            public void onTimeSelect(Date date) {
//                        tvTime.setText(getTime(date));
                SimpleDateFormat sdf = new SimpleDateFormat(format);
                callBack.onTimeSelect(sdf.format(date));
            }
        });
        pvTime.setTextSize(16);
        //弹出时间选择器
        pvTime.show();
    }


    /**
     * 底部滚轮点击事件回调
     */
    public interface OnWheelViewClick {
        void onClick(View view, int postion);
    }

    /**

    public static void alertBottomWheelOption(Context context, ArrayList<?> list, final OnWheelViewClick click) {

        final PopupWindow popupWindow = new PopupWindow();

        View view = LayoutInflater.from(context).inflate(R.layout.layout_bottom_wheel_option, null);
        TextView tv_confirm = (TextView) view.findViewById(R.id.btnSubmit);
        final WheelView wv_option = (WheelView) view.findViewById(R.id.wv_option);
        wv_option.setAdapter(new ArrayWheelAdapter(list));
        wv_option.setCyclic(false);
        wv_option.setTextSize(16);
        tv_confirm.setOnClickListener(new View.OnClickListener() {

        });

                popupWindow.dismiss();
            }
        });
        view.setOnTouchListener(new View.OnTouchListener() {
            @Override
            public boolean onTouch(View view, MotionEvent motionEvent) {
                int top = view.findViewById(R.id.ll_container).getTop();
                if (motionEvent.getAction() == MotionEvent.ACTION_UP) {
                    int y = (int) motionEvent.getY();
                    if (y < top) {
                        popupWindow.dismiss();
                    }
                }
                return true;

        popupWindow.showAtLocation(((ViewGroup) ((Activity) context).findViewById(android.R.id.content)).getChildAt(0), Gravity.CENTER, 0, 0);
    }
