Android自定义DataTimePicker（日期选择器）
笔者有一段时间没有发表关于Android的文章了，关于Android自定义组件笔者有好几篇想跟大家分享的，后期会记录在博客中。本篇博客给大家分享的是自定义一个日期选择器，可以让用户同时选择年月日和当前时间。
先看看效果：
实现的效果就是在同一个布局上显示日期选择和时间选择。
自定义一个类：

android5.0补充内容:
android5.0时代,日期选择器变得更简单了,下面来看看:
// 日期选择器,
DatePickerDialog dialog = new DatePickerDialog(ReasonDescriptionActivity.this,
AlertDialog.THEME_DEVICE_DEFAULT_DARK,
new DatePickerDialog.OnDateSetListener() {
@Override
public void onDateSet(DatePicker view, int year, int monthOfYear,
int dayOfMonth) {
Log.d("TAG",year+"::"+monthOfYear+"::"+dayOfMonth);
chooseDate.setText(year+"-"+monthOfYear+"-"+dayOfMonth);
}
},2014,1,1);
dialog.show();// 时间选择器
TimePickerDialog dialog = new TimePickerDialog(ReasonDescriptionActivity.this,
AlertDialog.THEME_DEVICE_DEFAULT_DARK,
new TimePickerDialog.OnTimeSetListener() {
@Override
public void onTimeSet(TimePicker view, int hourOfDay, int minute) {
Log.d("TAG", hourOfDay + "::" + minute);
if(minute < 10) {
chooseTime.setText(hourOfDay+":"+"0"+minute);
} else {
chooseTime.setText(hourOfDay+":"+minute);
}
}
},12,0,true);
dialog.show();这样就变得更加简单了,直接利用系统内部组件即可,定义一个dialog即可!
