Android 在日期选择器中设置自定义日期的步骤

我正在尝试创建一个应用程序，其中有两个字段，“fromDate”和“toDate”。约束条件是“fromDate”应大于或等于当前日期，“toDate”应大于或等于fromDate。我希望使用此约束打开日期选择器。有人能帮我怎么做到这一点吗

我使用以下代码正确获取“fromDate”

myCalendar = Calendar.getInstance();
    year = myCalendar.get(Calendar.YEAR);
    month = myCalendar.get(Calendar.MONTH);
    day = myCalendar.get(Calendar.DAY_OF_MONTH);

date = new DatePickerDialog.OnDateSetListener() {

        @Override
        public void onDateSet(DatePicker view, int year, int monthOfYear,
                int dayOfMonth) {
            // TODO Auto-generated method stub
            myCalendar.set(Calendar.YEAR, year);
            myCalendar.set(Calendar.MONTH, monthOfYear);
            myCalendar.set(Calendar.DAY_OF_MONTH, dayOfMonth);
            updateLabel();
        }

    };

fromDate_textView.setOnClickListener(new View.OnClickListener() {

        @Override
        public void onClick(View v) {
            // TODO Auto-generated method stub
            datePickerDialog = new DatePickerDialog(
                    Sell_Product_Activity.this, date, myCalendar
                            .get(Calendar.YEAR), myCalendar
                            .get(Calendar.MONTH), myCalendar
                            .get(Calendar.DAY_OF_MONTH));
            datePickerDialog.show();
            datePickerDialog.getDatePicker().setMinDate(
                    System.currentTimeMillis() - 1000);
        }
    });

同样，任何人都可以帮助我如何从fromDate_textView获取日期，并将“toDate”设置为大于或等于该日期。

试试：

   Calendar cal=Calendar.getInstance(Locale.ENGLISH);
    dp.init(cal.getTime().getYear()+1900, cal.getTime().getMonth(), cal.getTime().getDay(), this);

试试看：

   Calendar cal=Calendar.getInstance(Locale.ENGLISH);
    dp.init(cal.getTime().getYear()+1900, cal.getTime().getMonth(), cal.getTime().getDay(), this);

使用以下代码：

    //onCreate
    {
    fromDate_textView.setOnClickListener(new View.OnClickListener() {

        @Override
        public void onClick(View v) {
            // TODO Auto-generated method stub
            myCalendar  = Calendar.getInstance();

            year  = c.get(Calendar.YEAR);
            month  = c.get(Calendar.MONTH);
            day  = c.get(Calendar.DAY_OF_MONTH);

            DatePickerDialog dialog = new DatePickerDialog(Home.this,
                    mDateSetListener, year, month , day );

            dialog.show();
        }
    });
}

private DatePickerDialog.OnDateSetListener mDateSetListener = new DatePickerDialog.OnDateSetListener() {
        public void onDateSet(DatePicker view, int y, int m,
                int d) {
            year = y;
            month  = m+ 1;
            day  = d;

            String date = new StringBuilder().append(day).append("-").append(month)
                .append("-").append(year).append("").toString();

            fromDate_textView.setText(date);
        }
    };

使用以下代码：

    //onCreate
    {
    fromDate_textView.setOnClickListener(new View.OnClickListener() {

        @Override
        public void onClick(View v) {
            // TODO Auto-generated method stub
            myCalendar  = Calendar.getInstance();

            year  = c.get(Calendar.YEAR);
            month  = c.get(Calendar.MONTH);
            day  = c.get(Calendar.DAY_OF_MONTH);

            DatePickerDialog dialog = new DatePickerDialog(Home.this,
                    mDateSetListener, year, month , day );

            dialog.show();
        }
    });
}

private DatePickerDialog.OnDateSetListener mDateSetListener = new DatePickerDialog.OnDateSetListener() {
        public void onDateSet(DatePicker view, int y, int m,
                int d) {
            year = y;
            month  = m+ 1;
            day  = d;

            String date = new StringBuilder().append(day).append("-").append(month)
                .append("-").append(year).append("").toString();

            fromDate_textView.setText(date);
        }
    };
