将日期上限和下限设置为日期选择器对话框

我创建了一个活动，其中有一个用于插入用户出生日期的字段。 我使用了日期选择器来实现这一目标。

这是我正在做的源代码：

// onclick dob edittext open date picker dialog dob.setFocusableInTouchMode(false); dob.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { //open date picker showDialog(DATE_DIALOG_ID); } }); //======================For picking birth day========================== // Creating dialog @Override protected Dialog onCreateDialog(int id) { Calendar c = Calendar.getInstance(); int cyear = c.get(Calendar.YEAR); int cmonth = c.get(Calendar.MONTH); int cday = c.get(Calendar.DAY_OF_MONTH); switch (id) { case DATE_DIALOG_ID: return new DatePickerDialog(this, mDateSetListener, cyear, cmonth, cday); } return null; } private DatePickerDialog.OnDateSetListener mDateSetListener = new DatePickerDialog.OnDateSetListener() { // onDateSet method public void onDateSet(DatePicker view, int year, int monthOfYear, int dayOfMonth) { // String date_selected = String.valueOf(monthOfYear+1)+" /" // +String.valueOf(dayOfMonth)+" /" // +String.valueOf(year); String date_selected = String.valueOf(dayOfMonth)+" /" +String.valueOf(monthOfYear+1)+" /" +String.valueOf(year); //Toast.makeText(RegisterActivity.this, "Selected Date is ="+date_selected, Toast.LENGTH_SHORT).show(); dob.setText(date_selected); } }; //======================For picking birth day========================== 

现在我想做的是，将日期选择器限制在特定年份。 像这样：

 int maxYear = c.get(Calendar.YEAR) - 15; // this year ( 2013 ) - 15 = 1998 int maxMonth = c.get(Calendar.MONTH); int maxDay = c.get(Calendar.DAY_OF_MONTH); int minYear = maxYear-49; int minMonth = 0; // january int minDay = 25; 

我该怎么做才能将上面提到的边界设置为日期选择器？

// – – – – – – – – 编辑 – – – – – – – – – – – – – –

我做过这样的事情：

 //======================For picking birth day========================== // Creating dialog @Override protected Dialog onCreateDialog(int id) { Calendar c = Calendar.getInstance(); maxYear = c.get(Calendar.YEAR) - 15; // this year ( 2013 ) - 15 = 1998 maxMonth = c.get(Calendar.MONTH); maxDay = c.get(Calendar.DAY_OF_MONTH); switch (id) { case DATE_DIALOG_ID: return new DatePickerDialog(this, mDateSetListener, maxYear, maxMonth, maxDay); } return null; } DatePickerDialog.OnDateSetListener mDateSetListener = new DatePickerDialog.OnDateSetListener() { int minYear = maxYear-49; int minMonth = 0; // january int minDay = 25; public void onDateChanged(DatePicker view, int year, int monthOfYear,int dayOfMonth) { Date current = new Date(year, monthOfYear, dayOfMonth); Date minDate = new Date(minYear, minMonth, minDay); Date maxDate = new Date(maxYear, maxMonth, maxDay); if( current.getTime()  maxDate.getTime() ) { //Set to max Date } } @Override public void onDateSet(DatePicker view, int year, int monthOfYear, int dayOfMonth) { // TODO Auto-generated method stub String date_selected = String.valueOf(dayOfMonth)+" /" +String.valueOf(monthOfYear+1)+" /" +String.valueOf(year); //Toast.makeText(RegisterActivity.this, "Selected Date is ="+date_selected, Toast.LENGTH_SHORT).show(); dob.setText(date_selected); } }; //======================For picking birth day========================== 

这是固定上限，但下限或minDate没有得到修复！ 什么是要做？

Set OnDateChangedListener()对于DatePicker和onDateChanged函数内部，如果日期设置大于决定限制，如果是这样DatePicker.updateDate(minYear, minMonth, minDay); 使用此方法重置它。

 Date minDate = new Date(1990, 10, 25); Date maxDate = new Date(2013, 4, 15); OnDateChangedListener listener = new OnDateChangedListener() { @Override public void onDateChanged(DatePicker view, int year, int monthOfYear, int dayOfMonth) { Date current = new Date(year, monthOfYear, dayOfMonth); if( current.getTime() < minDate.getTime() ) { //set to minimum date }else if( current.getTime() > maxDate.getTime() ) { //Set to max Date } } }; YourDatePicker.init(2013, 4, 15, listener);
