問題 - 使用兩個日期時間選擇器

Question

我試圖使用兩個日期和時間選擇器（如fromdate和To date）來選擇日期。如果我從日期選擇，我可以從日期到文本視圖。但如果我選擇第二個datepicker（todate）更新相同的textview（Fromdate textview）。

 public class F2Activity extends InfosoftActivity

Answer 1

如果你想顯示在您的應用程序中使用的DatePicker然後日期超過一次沒有需要使用兩次DATE_DIALOG_ID。您只能使用一個並滿足您的要求。我在這裏發佈的代碼，我希望它會幫助你。

在點擊按鈕

btnFromDate.setOnClickListener(clkListener); 
btnToDate.setOnClickListener(clkListener); 

然後

public OnClickListener clkListener = new OnClickListener() 
    { 
     @Override 
     public void onClick(View v) 
     { 
      if(v == btnFromDate) 
      { 
       showDateDialog(editTextFromDate, Calendar.getInstance()); 
      } 
      if(v == btnToDate) 
      { 
       showDateDialog(editTextToDate, Calendar.getInstance()); 
      } 
       } 
    }; 

然後

EditText activeDateDisplay ; 
Calendar activeDate; 

public void showDateDialog(EditText dateDisplay, Calendar date) 
    { 
     activeDateDisplay = dateDisplay; 
     activeDate = date; 
     showDialog(DATE_DIALOG_ID); 
    } 

然後

CharSequence strFormate_Date; 
int DATE_DIALOG_ID = 0; 

@Override 
    protected Dialog onCreateDialog(int id) 
    { 
     switch (id) 
     { 
      case DATE_DIALOG_ID: 
      { 
       return new DatePickerDialog(Activity.this, mDateSetListener, activeDate.get(Calendar.YEAR), activeDate.get(Calendar.MONTH), activeDate.get(Calendar.DAY_OF_MONTH)); 
      } 
     } 
     return null; 
    } 

    private DatePickerDialog.OnDateSetListener mDateSetListener = new DatePickerDialog.OnDateSetListener() 
    { 
     public void onDateSet(DatePicker view, int year, int monthOfYear, int dayOfMonth) 
     { 
      activeDate.set(Calendar.YEAR, year); 
      activeDate.set(Calendar.MONTH, monthOfYear); 
      activeDate.set(Calendar.DAY_OF_MONTH, dayOfMonth); 
      updateDisplay(activeDateDisplay, activeDate); 
      unregisterDateDisplay(); 
     } 
    }; 
    private void unregisterDateDisplay() 
    { 
     activeDateDisplay = null; 
     activeDate = null; 
     strFormate_Date = null; 
    } 

    private void updateDisplay(EditText dateDisplay, Calendar date) 
    { 
     Time chosenDate = new Time(); 
     chosenDate.set(date.get(Calendar.DAY_OF_MONTH), date.get(Calendar.MONTH), date.get(Calendar.YEAR)); 
     long dtDob = chosenDate.toMillis(true); 
     strFormate_Date = DateFormat.format("dd/MM/yyyy", dtDob); 
     dateDisplay.setText(""+strFormate_Date); 
    } 

我希望它能解決你的問題。如果您對此有任何疑問，那麼您可以問我。
