Android 自带日期(DatePicker)和时间(TimePicker)选择器使用
一、效果图
本文提供了 Android 自带日期选择器（DatePicker和DatePickerDialog）、时间选择器（TimePicker和TimePickerDialog）的简单使用方法， 完整代码收录在GitHup项目中，
地址： https://github.com/GinGod/BasisDependency ，相关类 BasisTimesUtils.java 和 DateTimePickerActivity.java ,
因使用比较简单， 本文只是给出效果图和工具类代码，具体逻辑可自行参考注释理解。
具体效果图如下：
1、年月日选择器
2.年月选择器
3、月日选择器
4、时间选择器
5、嵌套在布局中
二、使用工具类
提供了一个工具类， 里面包含了 DatePickerDialog 和 TimePickerDialog 的简单使用， 可自定义设置背景， 标题， 不显示年或日等

void onCancel();
}
/**

*/
public interface OnTimerPickerListener {

}
}三、使用方法
提供了几个简便使用的方法
/**
* 时间选择
*/
private void showTimerPicker() {
BasisTimesUtils.showTimerPickerDialog(mActivity, true, "请选择时间", 21, 33, true, new BasisTimesUtils.OnTimerPickerListener() {
@Override
public void onConfirm(int hourOfDay, int minute) {
toast(hourOfDay + ":" + minute);
}
@Override
public void onCancel() {
toast("cancle");
}
});
}
/**
* 月日选择
*/
private void showMonthDayPicker() {
BasisTimesUtils.showDatePickerDialog(context, false, "请选择月日", 2015, 8, 28, new BasisTimesUtils.OnDatePickerListener() {
@Override
public void onConfirm(int year, int month, int dayOfMonth) {
toast(year + "-" + month + "-" + dayOfMonth);
}
@Override
public void onCancel() {
toast("cancle");
}
}).setYearGone();
}
/**
* 年月选择
*/
private void showYearMonthPicker() {
BasisTimesUtils.showDatePickerDialog(context, true, "", 2015, 12, 22,
new BasisTimesUtils.OnDatePickerListener() {
@Override
public void onConfirm(int year, int month, int dayOfMonth) {
toast(year + "-" + month + "-" + dayOfMonth);
}
@Override
public void onCancel() {
toast("cancle");
}
}).setDayGone();
}
/**
* 年月日选择
*/
private void showYearMonthDayPicker() {
BasisTimesUtils.showDatePickerDialog(context, BasisTimesUtils.THEME_HOLO_DARK, "请选择年月日", 2015, 1, 1, new BasisTimesUtils.OnDatePickerListener() {
@Override
public void onConfirm(int year, int month, int dayOfMonth) {
toast(year + "-" + month + "-" + dayOfMonth);
}
@Override
public void onCancel() {
toast("cancle");
}
});
}四、在布局中使用DatePicker和TimePicker
1、布局文件如下， 需要添加属性： android:theme="@android:style/Theme.Holo.Light"
2、代码中设置变化监听
//日期选择器初始化和变化监听
dp_datetimepicker_date.init(2016, 1, 1, new DatePicker.OnDateChangedListener() {
@Override
public void onDateChanged(DatePicker view, int year, int monthOfYear, int dayOfMonth) {
BasisLogUtils.e("onDateChanged: " + year + "-" + monthOfYear + "-" + dayOfMonth);
}
});
//时间选择器初始化和变化监听
tp_datetimepicker_time.setIs24HourView(true);
tp_datetimepicker_time.setHour(16);
tp_datetimepicker_time.setMinute(36);
tp_datetimepicker_time.setOnTimeChangedListener(new TimePicker.OnTimeChangedListener() {
@Override
public void onTimeChanged(TimePicker view, int hourOfDay, int minute) {
BasisLogUtils.e(hourOfDay + ":" + minute);
}
});五、总结
1、DatePicker和TimePicker是系统自带的选择器， 使用比较简单， 基本可满足对选择器没特殊要求的日常开发
2、高版本提供了新的显示方式， 可通过设置主题为 THEME_DEVICE_DEFAULT_LIGHT 和 THEME_DEVICE_DEFAULT_DARK 查看效果， 大家可自行尝试
