如何在android中设置日期选择器的最小和最大限制？

概述我正在开发一个应用程序,我正在使用自定义日期和时间选择器. 我已经创建了一个对话框,里面我现在分别显示日期和时间选择器,我想设置日期选择器的最小和最大限制. 例如,一个人不应该从今天开始选择前一个日期,也不能超过一个月. 这是我的代码 AlertDialog.Builder builder = new AlertDialog.Builder(getActivity()); 我正在开发一个应用程序,我正在使用自定义日期和时间选择器.

请帮忙.谢谢

解决方法 试试这个,这从今天到datepicker对话框中的下一个5年日期显示.

public class MainActivity extends Activity {    TextVIEw txtDatePicker;    Calendar cal,cal1;    long maxDate;    Date date;    @OverrIDe    protected voID onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentVIEw(R.layout.activity_main);        cal = Calendar.getInstance();        cal1 = Calendar.getInstance();        txtDatePicker = (TextVIEw) findVIEwByID(R.ID.txtDatePicker);        txtDatePicker.setonClickListener(new OnClickListener() {            @OverrIDe            public voID onClick(VIEw arg0) {                // Todo auto-generated method stub                DatePickerDialog dialog = new DatePickerDialog(MainActivity.this,new OnDateSetListener() {                    @OverrIDe                    public voID onDateSet(DatePicker arg0,int arg1,int arg2,int arg3) {                        // Todo auto-generated method stub                        Toast.makeText(MainActivity.this,""+arg1+"/"+(arg2+1)+"/"+arg3,Toast.LENGTH_SHORT).show();                    }            },cal.get(Calendar.YEAR),cal.get(Calendar.MONTH),cal.get(Calendar.DAY_OF_MONTH));            dialog.getDatePicker().setMinDate(System.currentTimeMillis());            cal1.add(Calendar.YEAR,5);            dialog.getDatePicker().setMaxDate(cal1.getTimeInMillis());            dialog.show();        }    });  }}
