Wie löst man IllegalArgumentException für Date Picker?

Question

Ich sehe den datePicker, wenn ich auf edidtext klicke.

public class DateDialog extends DialogFragment implements DatePickerDialog.OnDateSet`enter code here`Listener { 


EditText txtDate ; 
    public DateDialog(View view){ 
     txtDate=(EditText)view; 
    } 
    public Dialog onCreateDialog(Bundle savedInstanceState){ 
     final Calendar c = Calendar.getInstance(); 
     int day = c.get(Calendar.DAY_OF_MONTH); 
     int year = c.get(Calendar.YEAR); 
     int month = c.get(Calendar.MONTH); 
     return new DatePickerDialog(getActivity(), this, year ,month,day) ; 

    } 
    public void onDateSet (DatePicker view, int year , int month ,int day){ 
     String date = day+ "-" + (month + 1)+"-"+year; 
     txtDate.setText(date); 

    } 


} 

Dann gehen die Datumswerte in den editText.

protected void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.activity_add_page_); 


    } 
    public void onStart(){ 
     super.onStart(); 
     EditText txtDate = (EditText)findViewById(R.id.editDate); 
     txtDate.setOnFocusChangeListener(new View.OnFocusChangeListener() { 

      @Override 
      public void onFocusChange(View v, boolean hasFocus) { 

       if(hasFocus){ 
        DateDialog dialog = new DateDialog(v); 
        FragmentTransaction ft = getSupportFragmentManager().beginTransaction(); 
        dialog.show(ft, "DatePicker"); 
      } 
     } 
     }); 

meine Methode hinzuzufügen.

private String getDate() { 
     SimpleDateFormat dateFormat = new SimpleDateFormat 
     ("dd-MM-yyyy", Locale.getDefault()); 
     Date date = new Date(); 
     return dateFormat.format(date); 
    } 

    public long addPage(Page page){ 

     ContentValues values = new ContentValues(); 
     values.put(PageSQLITE.COL_DATE_PAGE, getDate()); 
     values.put(PageSQLITE .COL_TITLE_PAGE,page.getTitrePage()); 

     return bdd.insert(PageSQLITE.TABLE_PAGE, null, values); 

Wenn ich "onclick" verwende, um Datumswerte zu speichern, habe ich IllegalArgumentException.

private String strTitle; 
private String datePage; 

    public void onClickAdd(View v) { 

      strTitle = ((EditText) findViewById(R.id.editTitle)).getText().toString(); 
      datePage = ((EditText) findViewById(R.id.editDate)).getText().toString(); 

       Page page = new Page(strTitle, new Date(datePage)); 
       PageMgr pageMgr = new PageMgr(this); 
       pageMgr.open(); 

    pageMgr.addPage(page); 

      } 
     } 

Endlich sehe ich diese Nachricht.

Answer 1

Na, haben Sie ein Leerzeichen hier: "dd-MM-yyyy "; Löschen Sie es und ich denke, es wird funktionieren :)

Answer 2

I finally find the answer just: 

    wrong date 
    SimpleDateFormat dateFormat = new SimpleDateFormat 
      ("dd-MM-yyyy", Locale.getDefault()); 

    correct date 
    SimpleDateFormat dateFormat = new SimpleDateFormat 
      ("dd/MM/yyyy", Locale.FRENCH); 

and similar for 

public void onDateSet (DatePicker view, int year , int month ,int day){ 
    String date = day+ "/" + (month + 1)+"/"+year ; 
    txtDate.setText(date); 

Answer 3

Sie diese Funktionalität in einer einfachen Art und Weise umsetzen können. Das EditText-Objekt muss nicht an das Date Picker-Fragment übergeben werden. Sie müssen nur eine Schnittstelle erstellen und diese Schnittstelle in Aktivität/Fragment implementieren. und rufen Sie die Methode von Date Picker Fragment auf.

Sie können Textview anstelle von Edit Test verwenden und bei einem Klick auf die Textansicht können Sie das Datumsdialogfragment anzeigen.

dateTextView.setonClickListener(new OnClickListener{ 
    @Override 
public void onClick(View v) { 
    Dialog dialog; 
    switch (v.getId()) { 
     case R.id.render_date: 
      try { 

       Calendar calendar = Calendar.getInstance(); 
       dialog = new DatePickerDialog(EventDetailActivity.this, this, calendar.get(Calendar.YEAR), 
         calendar.get(Calendar.MONTH), calendar.get(Calendar.DAY_OF_MONTH)); 
       dialog.setCancelable(true); 
       dialog.show(); 
      } catch (ParseException e) { 
       e.printStackTrace(); 
      } 
      break; 
    } 
} 

}) 

Implementieren Sie die DatePickerDialog.OnDateSetListener-Schnittstelle in Ihrer Aktivität/Ihrem Fragment.

@Override 
    public void onDateSet(DatePicker view, int year, int monthOfYear, int dayOfMonth) { 
     TextView textView = (TextView) findViewById(R.id.date); 
textView.setText("**Set your date here**"); 
    }
