Welche Set aktuelles Datum als Standarddatum und ich mag Benutzer hinter 15 Tagen ab, damit Strom Datum nicht unter diesem Datum. Bitte helfen Sie, dies zu lösen.

Answer 1

DatePickerDialog ist ein Dialog Aber DatePickerDialog.OnDateSetListener ist kein Dailog, der gegossen werden kann. Zeigen Sie also DatePickerDialog anstatt datePickerListener anzuzeigen. Es ist die Linie der Fehler

((Dialog) datePickerListener).show(); 

die example Sehen Sie, wie DatePickerDialog erstellt und verwendet wird.

Answer 2

//Current date 
String currentDateTimeString = DateFormat.getDateTimeInstance().format(new Date()); 

// editText is the EditText that should display it 
editText.setText(currentDateTimeString); 

für 15 Tage zu begrenzen, Sie, wenn sonst Zustand, bevor Sie das Datum verwenden können text.So zu bearbeiten, wenn Benutzer Datum Wählt vor 15 Tagen das Bearbeiten von Text leer bleibt

Answer 3

Es gibt einige Fehler, die ich habe im Code bemerkt, 1) Ersetzen

calIcon.setOnClickListener(new Button.OnClickListener() 

mit

calIcon.setOnClickListener(new View.OnClickListener() 

2) Unterhalb Art Gießen verursacht den Absturz

((Dialog) datePickerListener).show(); 

Sie sollten eine Instanz von Dialog, bauen sie mit erfordern Attribute und legen Sie den Hörer erstellen. Rufen Sie dann die show() -Methode darauf auf. Siehe, Datepicker: How to popup datepicker when click on button and store value in variable
