Android 日期时间选择器

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>

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
最近更新代码到github上面了
