Displaying the Time in AM/PM format in android
提问by Rahul Kalidindi
I am getting the time using a time picker and displaying the time in the text view using following code...
我正在使用时间选择器获取时间并使用以下代码在文本视图中显示时间...
private TimePickerDialog.OnTimeSetListener mTimeSetListener = new TimePickerDialog.OnTimeSetListener() {
public void onTimeSet(TimePicker view, int hourOfDay, int minute) {
Toast.makeText(SendMail.this, "Your Appointment time is "+hourOfDay+":"+minute, Toast.LENGTH_SHORT).show();
TextView datehid = (TextView)findViewById(R.id.timehidden);
datehid.setText(String.valueOf(hourOfDay)+ ":"+(String.valueOf(minute)));
}
};
Now, the issue is when i set the time as 8:00 pm then i get the time displayed as 20:0... I want to display the time as 8:00 pm... How can i do that???
现在，问题是当我将时间设置为 8:00 pm 然后我将时间显示为 20:0...我想将时间显示为 8:00 pm...我该怎么做？？？

I have done like this to achieve it.
我这样做是为了实现它。
private TimePickerDialog.OnTimeSetListener mTimeSetListener = new TimePickerDialog.OnTimeSetListener() {
public void onTimeSet(TimePicker view, int hourOfDay, int minute) {
TextView datehid = (TextView)findViewById(R.id.timehidden);
if(hourOfDay>12) {
datehid.setText(String.valueOf(hourOfDay-12)+ ":"+(String.valueOf(minute)+"pm"));
} else if(hourOfDay==12) {
datehid.setText("12"+ ":"+(String.valueOf(minute)+"pm"));
} else if(hourOfDay<12) {
if(hourOfDay!=0) {
datehid.setText(String.valueOf(hourOfDay) + ":" + (String.valueOf(minute) + "am"));
} else {
datehid.setText("12" + ":" + (String.valueOf(minute) + "am"));
}
}
}
};

SimpleDateFormat df = new SimpleDateFormat("HH:mm:ss a");
String currentTime = df.format(currnetDateTime.getTime());

Calendar now = Calendar.getInstance();
if(now.get(Calendar.AM_PM) == Calendar.AM){
// AM
System.out.println(""+now.get(Calendar.HOUR)+":AM");
}else{
// PM
System.out.println(""+now.get(Calendar.HOUR)+":PM");
}

int am_pm=mycalendar.get(Calendar.AM_PM);
String amOrpm=((am_pm==Calendar.AM)?"am":"pm");
But as per my opinion simpleDateFormat would be the best use, like this:
但在我看来 simpleDateFormat 将是最好的用途，像这样：
final Calendar c = Calendar.getInstance(TimeZone.getTimeZone("America/Chicago"));
SimpleDateFormat format = new SimpleDateFormat("h:mm a");
format.setTimeZone(c.getTimeZone());
String myFormatted time = format.format(c.getTime());
It's better as the calendar by default will return 00 for 12 pm, which you might don't want.
最好是默认情况下日历将在下午 12 点返回 00，这是您可能不想要的。

我这样做是为了实现它。
TimePickerDialog.OnTimeSetListener t = new TimePickerDialog.OnTimeSetListener() {
public void onTimeSet(TimePicker view, int hourOfDay, int minute) {
myCalendar.set(Calendar.HOUR_OF_DAY, hourOfDay);
myCalendar.set(Calendar.MINUTE, minute);
update_From_Time();
}
};
DateFormat frmTime=DateFormat.getTimeInstance();
protected void update_From_Time() {
s = frmTime.format(myCalendar.getTime());
btnFromTime.setText(s);
}

This worked for me:
这对我有用：
public void onTimeSet(TimePicker view, int hourOfDay, int minute) {
String am_pm = "";
Calendar datetime = Calendar.getInstance();
datetime.set(Calendar.HOUR_OF_DAY, hourOfDay);
datetime.set(Calendar.MINUTE, minute);
if (datetime.get(Calendar.AM_PM) == Calendar.AM)
am_pm = "AM";
else if (datetime.get(Calendar.AM_PM) == Calendar.PM)
am_pm = "PM";
String strHrsToShow = (datetime.get(Calendar.HOUR) == 0) ?"12":datetime.get(Calendar.HOUR)+"";
((Button)getActivity().findViewById(R.id.btnEventStartTime)).setText( strHrsToShow+":"+datetime.get(Calendar.MINUTE)+" "+am_pm );
}

// Best Result Give Bapu_Darbar:::
Date dt = new Date(); int hours = dt.getHours(); int min = dt.getMinutes(); int am_pm = Calendar.AM_PM;
if(hours>=1 || hours<=3 && am_pm == Calendar.AM){
spl_text.setText("Welcome \n Good Night,Sweet Dream");
}else if(hours>=4 || hours<=12 && am_pm == Calendar.AM){
spl_text.setText("Welcome \n Good Morning,Have A Nice Day");
}else if(hours>=13 || hours<=17 && am_pm == Calendar.PM){
spl_text.setText("Welcome \n Good Afternoon");
}else if(hours>=18 || hours<=20 && am_pm == Calendar.PM){
spl_text.setText("Welcome \n Good Evening");
}else if(hours>=21 || hours<=24 && am_pm == Calendar.PM){
spl_text.setText("Welcome \n Good Night,Sweet Dream");
}
