Android高仿IOS 滚轮选择控件

源码来自于：https://github.com/saiwu-bigkoo/Android-PickerView 站着巨人的肩膀上，做了一些调整 ， 调整后效果图  博客地址：http://blog.csdn.net/lv_fq/article/details/52338513 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); } /** * 弹出底部滚轮选择 * * @param context * @param list * @param click */ 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() { @Override public void onClick(View view) { popupWindow.dismiss(); click.onClick(view, wv_option.getCurrentItem()); } }); view.findViewById(R.id.btnCancel).setOnClickListener(new View.OnClickListener() { @Override public void onClick(View view) { // TODO: 2016/8/11 0011 取消 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.setContentView(view); popupWindow.setOutsideTouchable(true); popupWindow.setFocusable(true); popupWindow.setBackgroundDrawable(new BitmapDrawable()); popupWindow.setWidth(ViewGroup.LayoutParams.MATCH_PARENT); popupWindow.setHeight(ViewGroup.LayoutParams.MATCH_PARENT); popupWindow.showAtLocation(((ViewGroup) ((Activity) context).findViewById(android.R.id.content)).getChildAt(0), Gravity.CENTER, 0, 0); } ``` 具体调用方法请参考 Demo。 此外，后面把该项目中的 底部弹出效果做了一下整理，详情参考 http://blog.csdn.net/lv_fq/article/details/53154026
