解决方案

而不是使用的DatePicker 切换到使用的 Android的车轮库。 这是写由谷歌开发，它可以设置样式看起来像Android的的DatePicker 还提供了一致的外观和感觉上的旧手机。

这不是由你可以把什么样的领域要么这意味着你可以使用任何你想要的限制。

I have a Datepicker in a custom Dialog which shows the date and the user can select the date and I get the user selected date. Now I want to go further by showing other calendar

for e.g. Persian calendar date instead of the Gregorian calender date. Now in my app when the user selects the date from the datepicker I can return the Persian date in the log. but I don't know how to change the DatePicker to show perisan date.please help.

 @Override
 public boolean onCreateOptionsMenu(Menu menu)
 {
    menu.add("Add Detail").setIcon(R.drawable.ic_compose).setShowAsAction(MenuItem.SHOW_AS_ACTION_IF_ROOM | MenuItem.SHOW_AS_ACTION_WITH_TEXT);
    return true;
 }

 @Override
 public boolean onOptionsItemSelected(MenuItem item)
 {
    final Dialog dialog = new Dialog(this);
    dialog.setContentView(R.layout.custom);

    final EditText amount = (EditText) dialog.findViewById(R.id.amtEditText);
    final DatePicker datePicker = (DatePicker) dialog.findViewById(R.id.datePicker1);
    Button cancelButton = (Button) dialog.findViewById(R.id.canelButton);
    Button OKButton = (Button) dialog.findViewById(R.id.OKbutton);

    OKButton.setOnClickListener(new View.OnClickListener() 
    {
        @Override
        public void onClick(View v) 
        {
            Log.d("---------------", datePicker.getDayOfMonth() +" " 
                                   + datePicker.getMonth() + " " 
                                   + datePicker.getYear() + " " 
                                   + amount.getText());

            Toast.makeText(MainActivity.this, "Got click: "
                                 + datePicker.getDayOfMonth() + " " 
                                 + datePicker.getMonth() + " " 
                                 + datePicker.getYear(), Toast.LENGTH_SHORT).show();

            CivilDate civil = new CivilDate(datePicker.getYear(), datePicker.getMonth(), datePicker.getDayOfMonth());
            PersianDate perDate = DateConverter.civilToPersian(civil);

            Log.d("-------", perDate.getDayOfMonth()+ " " + (perDate.getMonth() + 1) + " " + perDate.getYear() + " " + perDate.getMonthName());
            datePicker.init(perDate.getYear(), (perDate.getMonth() + 1), perDate.getDayOfMonth(), null);
        }
    });

Instead of using the DatePicker switch to using the Android Wheel library. It's written by a Google Developer and it can be styled to look like the Android DatePicker it also provides consistent look and feel on older phones.

It's not restricted by what you can put in the fields either which means you can use anything you want.
