I have a datepicker. My app is pushing a notification. I want to display the date in 01-07-2013 MM-dd-yyyy format. Please check my code below:
//---Button view---
Button btnOpen = ( Button ) findViewById( R.id.btEventDone );
btnOpen.setOnClickListener( new View.OnClickListener() {
public void onClick(View v) {
String strT = title.getText().toString();
String strDes = description.getText().toString();
// check if user did not input anything
if( strT.isEmpty() || strDes.isEmpty() ){
Toast.makeText( getBaseContext(), "You have blank fields!", Toast.LENGTH_SHORT ).show();
}
else{
//---use the AlarmManager to trigger an alarm---
AlarmManager alarmManager = ( AlarmManager ) getSystemService( ALARM_SERVICE );
//---get current date and time---
Calendar calendar = Calendar.getInstance();
//---sets the time for the alarm to trigger---
calendar.set( Calendar.YEAR, date.getYear() );
calendar.set( Calendar.MONTH, date.getMonth() );
calendar.set( Calendar.DAY_OF_MONTH, date.getDayOfMonth() );
calendar.set( Calendar.HOUR_OF_DAY, time.getCurrentHour() );
calendar.set( Calendar.MINUTE, time.getCurrentMinute() );
calendar.set( Calendar.SECOND, 0 );
//---PendingIntent to launch activity when the alarm triggers---
Intent i = new Intent( CalendarEvent.this, DisplayNotification.class );
year = calendar.get( Calendar.YEAR );
month = calendar.get( Calendar.MONTH );
day = calendar.get( Calendar.DAY_OF_MONTH );
hour = calendar.get( Calendar.HOUR );
minute = calendar.get( Calendar.MINUTE );
Date d = new Date(year, month, day);
SimpleDateFormat dateFormatter = new SimpleDateFormat(
"MM-dd-yyyy");
String strDate = dateFormatter.format(d);
String strTitle = title.getText().toString();
String strDescription = description.getText().toString();
strDate = String.valueOf( month ) + "-" + String.valueOf( day ) + "-" + String.valueOf( year );
StringBuilder sb = new StringBuilder();
if(hour>=12){
sb.append(hour-12).append( ":" ).append(minute).append(" PM");
}else{
sb.append(hour).append( ":" ).append(minute).append(" AM");
}
String strTime = sb.toString();
//---assign an ID of 1---
i.putExtra( "NotifID", notifID );
i.putExtra( "Title", strTitle );
i.putExtra( "Description", strDescription );
i.putExtra( "Date", strDate );
i.putExtra( "Time", strTime );
PendingIntent displayIntent = PendingIntent.getActivity(
getBaseContext(), notifID, i, 0 );
//---sets the alarm to trigger---
alarmManager.set( AlarmManager.RTC_WAKEUP,
calendar.getTimeInMillis(), displayIntent );
finish();
}
}
});
}

Notification notif = new Notification(
R.drawable.ic_launcher,
"iHealthFirst: Notification!",
System.currentTimeMillis() );
CharSequence from = "iHealthFirst - New Notification";
CharSequence message = "This is your alert, click to view";
notif.setLatestEventInfo(this, from, message, detailsIntent);
notif.flags = Notification.FLAG_INSISTENT;
notif.defaults |= Notification.DEFAULT_SOUND;
//---100ms delay, vibrate for 250ms, pause for 100 ms and
// then vibrate for 500ms---
notif.vibrate = new long[] { 100, 250, 100, 500};
nm.notify( notifID, notif );
//---destroy the activity---
finish();

我当前的应用程序仅以这种格式显示 M-d-yyyy.我读过我们应该使用 SimpleDateFormat，但我不知道如何在我的应用程序中使用它.任何人都可以帮忙吗?谢谢.

推荐答案
检查这个:
year = calendar.get(Calendar.YEAR);
month = calendar.get(Calendar.MONTH);
day = calendar.get(Calendar.DAY_OF_MONTH);
if(month < 10){
month = "0" + month;
}
if(day < 10){
day = "0" + day ;
}
searchText.setText(day + "-" + month + "-" + year);
