下面是我的code：
公共类UserDob延伸活动{ TextView的tvDisplayDate;
DatePicker的datePickerBirthday; @覆盖
保护无效的onCreate（捆绑savedInstanceState）{
super.onCreate（savedInstanceState）;
的setContentView（R.layout.activity_user_dob）; 动作条AB = getActionBar（）;
ab.setDisplayUseLogoEnabled（假）;
ab.setDisplayShowHomeEnabled（真）;
ab.setDisplayOptions（ActionBar.DISPLAY_SHOW_CUSTOM）;
ab.setCustomView（R.layout.actionbar）;
ab.setDisplayHomeAsUpEnabled（真）;
ColorDrawable colorDrawable =新ColorDrawable（Color.parseColor（＃FFFFFF））;
ab.setBackgroundDrawable（colorDrawable）; datePickerBirthday =（的DatePicker）findViewById（R.id.d presult）;
tvDisplayDate =（的TextView）findViewById（R.id.textViewUserDate）; INT currentapiVersion = android.os.Build.VERSION.SDK_INT;
如果（currentapiVersion＆GT; = 11）{
datePickerBirthday.setCalendarViewShown（假）;
} SimpleDateFormat的sdfDateTime =新的SimpleDateFormat（YYYY-MM-DD，Locale.US）;
字符串dateStr = sdfDateTime.format（新的Date（System.currentTimeMillis的（）））; 串[] dateSplit = dateStr.split（ - ）;
INT currentYear =的Integer.parseInt（dateSplit [0]）;
INT currentMonth =的Integer.parseInt（dateSplit [1]）;
INT CURRENTDAY =的Integer.parseInt（dateSplit [2]）; //显示一周的日期和在TextView中
setHumanReadableDate（currentYear，currentMonth，CURRENTDAY）; //初始化日期选择器监听器
// currentMonth - 1，因为在选择器，0是一月
datePickerBirthday.init（currentYear，currentMonth - 1，CURRENTDAY，birthdayListener）;
}
//日期选择器监听器
OnDateChangedListener birthdayListener =新OnDateChangedListener（）{ @覆盖
公共无效onDateChanged（DatePicker的birthDayDatePicker，
INT NEWYEAR，诠释newMonth，诠释newDay）{ 尝试{ // currentMonth + 1，获取适当的一个月
setHumanReadableDate（NEWYEAR，newMonth + 1，newDay）; }赶上（NullPointerException异常五）{
e.printStackTrace（）;
}赶上（例外五）{
e.printStackTrace（）;
}
}
}; //显示用户更好的日期格式
公共无效setHumanReadableDate（INT NEWYEAR，诠释newMonth，诠释newDay）{
尝试{ 串clickedDate = NEWYEAR + - + newMonth + - + newDay;
SimpleDateFormat的SDF =新的SimpleDateFormat（YYYY-MM-DD）;
日期D = NULL;
尝试{
D = sdf.parse（clickedDate）;
}赶上（java.text.ParseException E）{
// TODO自动生成catch块
e.printStackTrace（）;
} SimpleDateFormat的sdfDateTime =新的SimpleDateFormat（MMMM DD，YYYY是EEEE，Locale.US）;
字符串dateStr = sdfDateTime.format（D）; tvDisplayDate.setText（dateStr）; }赶上（ParseException的E）{
e.printStackTrace（）;
}
}
}
解决方案
以上11 API
对于分钟日期可以使用
的android：MINDATE =MM / DD / YYYY
或setMinDate（时间长）
有关最大日期
的android：MAXDATE =MM / DD / YYYY//在XML
setMaxDate（新的Date（）的getTime（））; //当前时间

Here is my code :
public class UserDob extends Activity {
TextView tvDisplayDate;
DatePicker datePickerBirthday;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_user_dob);
ActionBar ab = getActionBar();
ab.setDisplayUseLogoEnabled(false);
ab.setDisplayShowHomeEnabled(true);
ab.setDisplayOptions(ActionBar.DISPLAY_SHOW_CUSTOM);
ab.setCustomView(R.layout.actionbar);
ab.setDisplayHomeAsUpEnabled(true);
ColorDrawable colorDrawable = new ColorDrawable(Color.parseColor("#FFFFFF"));
ab.setBackgroundDrawable(colorDrawable);
datePickerBirthday=(DatePicker)findViewById(R.id.dpResult);
tvDisplayDate = (TextView)findViewById(R.id.textViewUserDate);
int currentapiVersion = android.os.Build.VERSION.SDK_INT;
if (currentapiVersion >= 11) {
datePickerBirthday.setCalendarViewShown(false);
}
SimpleDateFormat sdfDateTime = new SimpleDateFormat("yyyy-MM-dd", Locale.US);
String dateStr = sdfDateTime.format(new Date(System.currentTimeMillis()));
String[] dateSplit = dateStr.split("-");
int currentYear = Integer.parseInt(dateSplit[0]);
int currentMonth = Integer.parseInt(dateSplit[1]);
int currentDay = Integer.parseInt(dateSplit[2]);
// to show date and day of week in the TextView
setHumanReadableDate(currentYear, currentMonth, currentDay);
// initialize date picker listener
// currentMonth - 1, because on the picker, 0 is January
datePickerBirthday.init(currentYear, currentMonth - 1, currentDay, birthdayListener);
}
// the date picker listener
OnDateChangedListener birthdayListener = new OnDateChangedListener() {
@Override
public void onDateChanged(DatePicker birthDayDatePicker,
int newYear, int newMonth, int newDay) {
try{
// currentMonth + 1, to retrieve proper month
setHumanReadableDate(newYear, newMonth + 1, newDay);
} catch (NullPointerException e) {
e.printStackTrace();
} catch (Exception e) {
e.printStackTrace();
}
}
};
// show the user a better date format
public void setHumanReadableDate(int newYear, int newMonth, int newDay){
try {
String clickedDate = newYear + "-" + newMonth + "-" + newDay;
SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd");
Date d = null;
try {
d = sdf.parse(clickedDate);
} catch (java.text.ParseException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
SimpleDateFormat sdfDateTime = new SimpleDateFormat("MMMM dd, yyyy 'is' EEEE", Locale.US);
String dateStr = sdfDateTime.format(d);
tvDisplayDate.setText(dateStr);
} catch (ParseException e) {
e.printStackTrace();
}
}
}
解决方案
Above API 11 For min date you can use
android:minDate="mm/dd/yyyy"
or setMinDate(long time)
For Max date
android:maxDate="mm/dd/yyyy" // In XML
setMaxDate(new Date().getTime());// Current time
