如何在android中使用日期选择器而不是编辑文本框？

现在我正在使用android中的一个web服务。该web服务分别具有两个输入值，即01/01/2012和07/07/2012。如何在android中使用日期选择器而不是编辑文本框？

单击调用按钮后，提供这些作为输入值后，我的项目会显示一些条形图。让其工作正常。在这里我使用两个编辑文本框来获取这些输入值。

但我想使用日期选择器小部件，而不是使用编辑文本框。所以我拖动了日期选择器小部件，我做了一些代码。

但现在问题是，输入值完全关闭数字和反斜杠？但在日期选择器小部件中，它显示字符和数字组合中的输入值，但我只需要使用日期选择器小部件。

日期选择器窗口小部件是在这种格式DD-MM-YYYY例如： - 01-JAN-1990

但我需要上述格式转换到01/01/1990。这个怎么做？

请找我的源引用

任何想法？

请解释你的问题，并分享一些代码 –

@Sas请再次访问我的问题，我已经更新我的问题与来源 – prabu

这个怎么样！

你保持文本字段和选择textfeild时，会出现一个DateTime选择对话框，并在文本框保留日期时间格式。

final Calendar c = Calendar.getInstance(); 
mYear = c.get(Calendar.YEAR); 
mMonth = c.get(Calendar.MONTH); 
mDay = c.get(Calendar.DAY_OF_MONTH); 
updateDisplay();

，并在更新的显示方法：

private void updateDisplay() { 
    checkdate.setText(
      new StringBuilder() 
      // Month is 0 based so add 1 
      .append(mMonth + 1).append("-") 
      .append(mDay).append("-") 
      .append(mYear).append(" ")); 
}

也增加了活动

@Override 
protected Dialog onCreateDialog(int id) { 
    // TODO Auto-generated method stub 
    switch (id) { 
    case DATE_DIALOG_ID: 
     return new DatePickerDialog(this, 
       mDateSetListener, 
       mYear, mMonth, mDay); 
} 
} 
@Override 
protected void onPrepareDialog(int id, Dialog dialog) { 
    // TODO Auto-generated method stub 
    switch (id) { 
    case DATE_DIALOG_ID: 
     ((DatePickerDialog) dialog).updateDate(mYear, mMonth, mDay); 
     break; 
    } 
} 
private DatePickerDialog.OnDateSetListener mDateSetListener = 
    new DatePickerDialog.OnDateSetListener() { 
    @Override 
    public void onDateSet(DatePicker view, int year, int monthOfYear, 
      int dayOfMonth) { 
     // TODO Auto-generated method stub 
     mYear = year; 
     mMonth = monthOfYear; 
     mDay = dayOfMonth; 
     updateDisplay(); 
    } 
};

和焦点监听器添加到文本框

textfield1.setOnFocusChangeListener(new OnFocusChangeListener(){ 
     @Override 
     public void onFocusChange(View v, boolean hasFocus) { 
      // TODO Auto-generated method stub 
      if(hasFocus){ 
       showDialog(DATE_DIALOG_ID); 
      } 
     } 
    });

希望其你需要什么。
