首先界面弹出PopupWindow动画的实现，具体的代码如下

进入动画

<code class="hljs xml has-numbering"><span class="hljs-pi"><?xml version="1.0" encoding="utf-8"?></span>
<span class="hljs-tag"><<span class="hljs-title">set</span> <span class="hljs-attribute">xmlns:android</span>=<span class="hljs-value">"http://schemas.android.com/apk/res/android"</span> ></span>

    <span class="hljs-tag"><<span class="hljs-title">translate
</span>        <span class="hljs-attribute">android:duration</span>=<span class="hljs-value">"500"</span>
        <span class="hljs-attribute">android:fromYDelta</span>=<span class="hljs-value">"100.0%p"</span>
        <span class="hljs-attribute">android:toYDelta</span>=<span class="hljs-value">"45"</span> /></span>

<span class="hljs-tag"></<span class="hljs-title">set</span>></span></code>
退出动画 

<code class="hljs xml has-numbering"><span class="hljs-pi">?xml version="1.0" encoding="utf-8"?></span>
<span class="hljs-tag"><<span class="hljs-title">set</span> <span class="hljs-attribute">xmlns:android</span>=<span class="hljs-value">"http://schemas.android.com/apk/res/android"</span> ></span>

    <span class="hljs-tag"><<span class="hljs-title">translate
</span>        <span class="hljs-attribute">android:duration</span>=<span class="hljs-value">"500"</span>
        <span class="hljs-attribute">android:fromYDelta</span>=<span class="hljs-value">"0.0"</span>
        <span class="hljs-attribute">android:toYDelta</span>=<span class="hljs-value">"100.0%p"</span> /></span>

<span class="hljs-tag"></<span class="hljs-title">set</span>></span></code>

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

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
