日期选择器是很多应用所具备的,比如设置一些任务的开始和结束时间。为了方便用户的同时也为了界面的好看,很多都是采用日期选择器,我在网上看了一下。很多的日期选择器个人感觉不是很好看,但是修改起来也有点麻烦,于是自己就写了一个demo。至于界面效果个人感觉也是很low,毕竟鄙人不是搞UI的,所以也就凑合着看吧。这些都不重要,因为这些是可以修改的。
如果想实现具有年月日的请看下面的注意里面的内容,下图是实现的分钟为00 15 30 45的如果想要0-59的请看下面的注意里面的内容
如果需要的是仿iOS的带有星期几的
首先界面弹出PopupWindow动画的实现,具体的代码如下
进入动画
- <?xml version="1.0" encoding="utf-8"?>
- <set xmlns:android="http://schemas.android.com/apk/res/android" >
- <translate
- android:duration="500"
- android:fromYDelta="100.0%p"
- android:toYDelta="45" />
- </set>
退出动画
- <?xml version="1.0" encoding="utf-8"?>
- <set xmlns:android="http://schemas.android.com/apk/res/android" >
- <translate
- android:duration="500"
- android:fromYDelta="0.0"
- android:toYDelta="100.0%p" />
- </set>

- }
- });
- }
- public void backgroundAlpha(float bgAlpha) {

- }
- }

请注意
MainActivity里面的显示时间的 tv_house_time.setText(DateUtils.currentTimeDeatil(begin));需要更改为
tv_house_time.setText(DateUtils.formateStringH(beginTime,DateUtils.yyyyMMddHHmm));否则现实的额时间为00:00
修改后的
将WheelMain里面的以下代码
- wv_mins.setAdapter(adapter);
- wv_mins.setCyclic(true);// 可循环滚动
- wv_mins.setLabel(“分”);// 添加文字
- int min = setMinute(m);
- wv_mins.setCurrentItem(min);
更换为
- wv_mins.setAdapter(new NumericWheelAdapter(
- 0, 59));
- wv_mins.setCyclic(true);// 可循环滚动
- wv_mins.setLabel(“分”);// 添加文字
- wv_mins.setCurrentItem(m);
还需要将
- int minute = Integer.valueOf(adapter.getItem(wv_mins.getCurrentItem()));
改为
- int minute = wv_mins.getCurrentItem();
会将分钟更改为从0到59
如果不想要时间只想要年月日的话只需要
- if (hasSelectTime) {
- wv_hours.setVisibility(View.GONE);
- wv_mins.setVisibility(View.GONE);
- } else {
- wv_hours.setVisibility(View.GONE);
- wv_mins.setVisibility(View.GONE);
- wv_day.setVisibility(View.GONE);
- }
将这段代码放开就可以了还要将以下绿色区域内的代码去掉
还需要将 MainActivty里的如下代码
- wheelMainDate.initDateTimePicker(year, month, day, hours,minute);
更改为
- wheelMainDate.initDateTimePicker(year, month, day);
还有 wheelMain里的
- if (!hasSelectTime) {
- sb.append((wv_year.getCurrentItem() + START_YEAR)).append("-")
- .append(strMon).append("-")
- .append(strDay).append(" ").append(strHour).append(":").append(strMin);
- }else{
- sb.append((wv_year.getCurrentItem() + START_YEAR)).append("-")
- .append(strMon).append("-")
- .append(strDay).append(" ").append(strHour).append(":").append(strMin);
- }
需要修改为
- if (!hasSelectTime) {
- sb.append((wv_year.getCurrentItem() + START_YEAR)).append("-")
- .append(strMon).append("-")
- .append(strDay);
- }else{
- sb.append((wv_year.getCurrentItem() + START_YEAR)).append("-")
- .append(strMon).append("-")
- .append(strDay);
- }
实现效果如下图
