android - 日付ピッカーからMM-DD-YYYYへのAndroid形式の日付

Question

私はデートピッカーを持っています。私のアプリは通知をプッシュしています。2013年1月7日MM-dd-yyyy形式で日付を表示したい。以下の私のコードを確認してください：

 //---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();
        }

        }
    }); 

}

AlarmDetails：

@Override
public void onCreate(Bundle savedInstanceState) 
{
    super.onCreate(savedInstanceState);
    setContentView(R.layout.alarmdetails);  

    //---look up the notification manager service---
    NotificationManager nm = ( NotificationManager ) 
        getSystemService( NOTIFICATION_SERVICE );

    title = ( EditText ) findViewById ( R.id.etDetailTitle );
    description = ( EditText ) findViewById ( R.id.etDetailDescription );
    date = ( EditText ) findViewById ( R.id.etDetailDate );
    time = ( EditText ) findViewById ( R.id.etDetailTime );
    done = ( Button ) findViewById ( R.id.btnAlarmDone );

    done.setOnClickListener(new View.OnClickListener() {

        public void onClick(View v) {
            // TODO Auto-generated method stub
            finish();
        }
    });

    //---cancel the notification---
    nm.cancel( getIntent().getExtras().getInt( "NotifID" ) ); 


    String strTitle = getIntent().getExtras().getString( "Title" );
    String strDescription = getIntent().getExtras().getString( "Description" );
    strDate = getIntent().getExtras().getString( "Date" );
    String strTime = getIntent().getExtras().getString( "Time" );
    title.setText( strTitle );
    description.setText( strDescription );
    date.setText( strDate );
    time.setText( strTime );


}

DisplayNotification：

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

//---get the notification ID for the notification; 
// passed in by the NotifyActivity---
int notifID = getIntent().getExtras().getInt( "NotifID" );
String strTitle = getIntent().getExtras().getString( "Title" );
String strDescription = getIntent().getExtras().getString( "Description" );
String strDate = getIntent().getExtras().getString( "Date" );
String strTime = getIntent().getExtras().getString( "Time" );

//---PendingIntent to launch activity if the user selects 
// the notification---
Intent i = new Intent( DisplayNotification.this, AlarmDetails.class );
i.putExtra( "NotifID", notifID );  
i.putExtra( "Title", strTitle );
i.putExtra( "Description", strDescription );
i.putExtra( "Date", strDate );
i.putExtra( "Time", strTime );

PendingIntent detailsIntent = 
    PendingIntent.getActivity(this, 0, i, 0);

NotificationManager nm = ( NotificationManager )
    getSystemService( NOTIFICATION_SERVICE );
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();
}

私の現在のアプリは、この形式のMd-yyyyでのみ表示されます。SimpleDateFormatを使用する必要があることを読みましたが、アプリでの使用方法がわかりません。誰か助けてもらえますか？ありがとう。

これを試して

int year = mDatePicker.getYear();
int month = mDatePicker.getMonth();
int day = mDatePicker.getDayOfMonth();

Calendar calendar = Calendar.getInstance();
calendar.set(year, month, day);

SimpleDateFormat format = new SimpleDateFormat("MM-dd-yyyy");
String strDate = format.format(calendar.getTime());

   month = calendar.get(Calendar.MONTH);
   day = calendar.get(Calendar.DAY_OF_MONTH);

    if(month < 10){

        month = "0" + month;
    }
    if(day < 10){

        day  = "0" + day ;

次のコードを追加できます。

Date d = new Date(year, month, day);
SimpleDateFormat dateFormatter = new SimpleDateFormat(
                "MM-dd-yyyy hh:mm");
strDate = dateFormatter.format(d);

後

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 );

したがって、strDateは希望する形式になります（MM-dd-yyyy）

                                    long dtDob = chosenDate.toMillis(true);

                                    strDate = DateFormat.format("MM/dd/yyyy", dtDob);

                                    txtDate.setText(strDate);
                        }}, year,month,day);

                      dateDlg.show();
               }
        });

2013年1月7日MM-dd-yyyy形式で日付を表示したい。

はい、以下の手順でこれを行うことができます。

ステップ1：最初に文字列を特定の日付形式に変換する必要があります

ステップ2： SimpleDateFormatを使用する日付をMM-dd-yyyy形式に変換する

ステップ3：文字列に変換して使用します。

あなたはこれのために以下のコードを使用することができます。

 public class DateFormat {

   public static void main(String[] args) {
    // Put here what your are getting as String
    String mytime="Jan 7, 2013"; 
    SimpleDateFormat dateFormat = new SimpleDateFormat(
            "MMM dd, yyyy"); //Step1: Convert yout String to perticular Date Formate according to your Date String your are getting
    Date myDate = null;
    try {
        myDate = dateFormat.parse(mytime);

    } catch (ParseException e) {
        e.printStackTrace();
    }

    //Step2
    SimpleDateFormat timeFormat = new SimpleDateFormat("MM-dd-yyyy");
    String finalDate = timeFormat.format(myDate); 
    //Step3: Here you will get your Final Date. Set your String now to textview.
       }
}

それがあなたを助けることを願っています。

この方法を試してください：

private int m_month, m_year, m_day;
 SimpleDateFormat dateParser = new SimpleDateFormat("MM-dd-yyyy",
            Locale.ENGLISH);
 m_month = m_calendar.get(Calendar.MONTH) + 1;
 m_year = m_calendar.get(Calendar.YEAR);
 m_day = m_calendar.get(Calendar.DAY_OF_MONTH);
 //for the datepicker listener.
 m_calendar.set(Calendar.YEAR, p_year);
 m_calendar.set(Calendar.MONTH, p_monthOfYear);
 m_calendar.set(Calendar.DAY_OF_MONTH, p_dayOfMonth);
 String m_sDate = dateParser.format(m_calendar.getTime()).toString();

私は自分のプロジェクトで次のことを試みました。それはあなたを助けるかもしれません。質問があれば聞いてください。

try{
    SimpleDateFormat sdf = new SimpleDateFormat("MM-dd-yyyy");
    Date originalDate = new Date();   //it will give today's date.
    String dateString = sdf.format(originalDate);
    Date formattedDate = sdf.parse(dateString);

}catch(Exception e){
    e.printStackTrace();
}
