Android 自定义弹框日期选择器弹框，年月日，时分，

之前有个项目要用到日期选择器，于是百度了有关方法，自己将其封装成了自定义控件

效果图

Android 自带的日期选择器和时间选择器为DatePicker 和 TimePicker，一个是年月日选择器，一个是时分选择器。

而在 Android 不同的 API 下它们的显示样式也不同。

因为此次封装是在弹框中显示的，所以选择了比较简单的样式

DatePicker如果要显示上图的样式，在 xml 布局中需如此设置

<DatePicker
    android:id="@+id/datePicker"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_centerHorizontal="true"
    android:calendarViewShown="false"
    android:datePickerMode="spinner"/>

TimePicker 要显示上图样式，则需要用代码设置布局的主题

LayoutInflater inflater = (LayoutInflater) getContext().getSystemService(Context.LAYOUT_INFLATER_SERVICE);
Context contextThemeWrapper = new ContextThemeWrapper(
        getContext(), android.R.style.Theme_Holo_Light);
LayoutInflater localInflater = inflater.cloneInContext(contextThemeWrapper);
View view = localInflater.inflate(R.layout.view_time_picker_dialog, null, false);

timePicker = (TimePicker) view.findViewById(R.id.timePicker);

要自定义Dialog的布局则需自己通过布局文件实例化 view 然后调用 setView（）

LayoutInflater inflater = (LayoutInflater) getContext().getSystemService(Context.LAYOUT_INFLATER_SERVICE);
Context contextThemeWrapper = new ContextThemeWrapper(
        getContext(), android.R.style.Theme_Holo_Light);
LayoutInflater localInflater = inflater.cloneInContext(contextThemeWrapper);
View view = localInflater.inflate(R.layout.view_time_picker_dialog, null, false);
setView(view);

标题选中下滑线切换效果

这种效果在我的另一篇文章里有点击打开链接

年月日选择如果想单纯显示年，月，日或隐藏某一模块可以用

// 是否 显示 年
if (!this.isYearVisible) {
    ((ViewGroup) ((ViewGroup) mDatePicker.getChildAt(0)).getChildAt(0)).getChildAt(0).setVisibility(View.GONE);
}

// 是否 显示 月
if (!this.isMonthVisible) {
    ((ViewGroup) ((ViewGroup) mDatePicker.getChildAt(0)).getChildAt(0)).getChildAt(1).setVisibility(View.GONE);
}

// 是否 显示 日
if (!this.isDayVisible) {
    ((ViewGroup) ((ViewGroup) mDatePicker.getChildAt(0)).getChildAt(0)).getChildAt(2).setVisibility(View.GONE);
}

标题为 RadioGroup，中间为 ViewPager，底部为 LinearLayout 放入两个Button

ViewPager有两页，一个 DatePicker，一个TimePikcer

这是布局代码
