废话不多说先看效果，效果不符合，就不要用看了。
安卓提供自己的日期选择和时间选择，但是样式并不是自己想要的，如果非要把他们放在一起，会发现，样式不好看，而且时间和日期选择控件的大小不好控制，甚至根本没法放在一行上，所以实现自定义日期时间选择器有两种方式
1.自己写自定义控件，需要能滚动的WheelView,虽然网上有三方的WheelView，但是我们自己还要懂自己如何计算日期时间，时间确实比较麻烦，我们要去学习日历，很费劲
2.就是自己去根据安卓自己的日期和时间控件，进行组合，而这样，我们就需要解决两个问题
a.样式问题；
自己添加了安卓自己的日期控件会发现，各个版本样式不一样，当在一个系统运行效果是这样，但换个系统，样式就不一样了。那么就需要自己强制定义一个样式，如上图的样式是android:Theme.Holo.Light.Dialog 需要在style.xml自定义样式MyDialogStyleBottom<!-- 自定义dialogActivity的样式 --><style name="MyDialogStyleBottom" parent="android:Theme.Holo.Light.Dialog"><item name="android:windowAnimationStyle">@style/AnimBottom</item><item name="android:windowFrame">@null</item><!-- 边框 --><item name="android:windowIsFloating">false</item><!-- 是否浮现在activity之上 --><item name="android:windowIsTranslucent">true</item><!-- 半透明 --><item name="android:windowNoTitle">true</item><!-- 无标题 --><item name="android:windowBackground">@android:color/transparent</item><!-- 背景透明 --><item name="android:backgroundDimEnabled">true</item><!-- 模糊 --></style>
那么需要自己的activity样式采用这个，就需要manifest配置如下
<span style="white-space:pre"></span><activityandroid:name=".DatePickActivity"android:theme="@style/MyDialogStyleBottom" ></activity>
b.就是控件大小问题用的时候，发现当强制将两个控件放在一行，会导致日期或时间显示不全，无论怎么调整布局宽度，都无法显示完全，在查看源码时后看到，安卓自己的时间和日期选择器都会用到numberpicker,就可以从这里着手，它们都是FrameLayout的子类，只需要找到其中的numberpicker，进行重新调整位置就行
<span style="white-space:pre"></span>/*** 数据初始化*/private void init() {datePicker.setCalendarViewShown(false);timePicker.setIs24HourView(true);resizePikcer(datePicker);// 调整datepicker大小resizePikcer(timePicker);// 调整timepicker大小String str = getIntent().getStringExtra("date");if (TextUtils.isEmpty(str)) {System.out.println("isempty");datestrold = "";datestr = "";} else {datestr = str;datestrold = str;}}
<span style="white-space:pre"></span>/*** 调整FrameLayout大小* * @param tp*/private void resizePikcer(FrameLayout tp) {List<NumberPicker> npList = findNumberPicker(tp);for (NumberPicker np : npList) {resizeNumberPicker(np);}}
<span style="white-space:pre"></span>/** 调整numberpicker大小*/private void resizeNumberPicker(NumberPicker np) {LinearLayout.LayoutParams params = new LinearLayout.LayoutParams(Util.dip2px(this, 45),LayoutParams.WRAP_CONTENT);params.setMargins(Util.dip2px(this, 5), 0, Util.dip2px(this, 5), 0);np.setLayoutParams(params);}
<span style="white-space:pre"></span>/*** 得到viewGroup里面的numberpicker组件* * @param viewGroup* @return*/private List<NumberPicker> findNumberPicker(ViewGroup viewGroup) {List<NumberPicker> npList = new ArrayList<NumberPicker>();View child = null;if (null != viewGroup) {for (int i = 0; i < viewGroup.getChildCount(); i++) {child = viewGroup.getChildAt(i);if (child instanceof NumberPicker) {npList.add((NumberPicker) child);} else if (child instanceof LinearLayout) {List<NumberPicker> result = findNumberPicker((ViewGroup) child);if (result.size() > 0) {return result;}}}}return npList;}
