Question

Iam使用Material Design Datepicker我可以从明天开始设置，但是今天的日期也会在日历i set for 29/11/2016 but it also showing 28/11/2016中显示如何禁用它以便用户无法选择它我使用Material Design DatePicker https://github.com/wdullaer/MaterialDateTimePicker

    GregorianCalendar g1=new GregorianCalendar();
    g1.add(Calendar.DATE, 1);
    GregorianCalendar gc = new GregorianCalendar();
    gc.add(Calendar.DAY_OF_MONTH, 30);
    dateButton.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
            DatePickerDialog datePickerDialog ;
            datePickerDialog = DatePickerDialog.newInstance(LoginSuccess.this, g1.get(Calendar.YEAR),
                    g1.get(Calendar.MONTH),
                    g1.get(Calendar.DAY_OF_MONTH));

            datePickerDialog.setTitle("Select Date");
            //datePickerDialog.setMinDate(g);
            GregorianCalendar c2=new GregorianCalendar();
            c2.setTimeInMillis(g1.getTimeInMillis()+(27*7*24*60*60*1000));
            //c2.add(Calendar.DAY_OF_MONTH, 30);
            List<Calendar> dayslist= new LinkedList<Calendar>();
            Calendar[] daysArray;
            Calendar cAux = Calendar.getInstance();
            while ( cAux.getTimeInMillis() <= gc.getTimeInMillis())
            {
                if (cAux.get(Calendar.DAY_OF_WEEK)!=1)
                {
                    Calendar c = Calendar.getInstance();
                    c.setTimeInMillis(cAux.getTimeInMillis());
                    dayslist.add(c);
                }
                cAux.setTimeInMillis(cAux.getTimeInMillis()+(24*60*60*1000));
            }
            daysArray = new Calendar[dayslist.size()];
            for (int i = 0; i<daysArray.length;i++)
            {
                daysArray[i]=dayslist.get(i);
            }
            //g1.setTimeInMillis(g.getTimeInMillis()+(7*24*60*60*1000));
            datePickerDialog.setMinDate(g1);
            datePickerDialog.setMaxDate(c2);
            datePickerDialog.show(getFragmentManager(), "DatePickerDialog");
            datePickerDialog.setSelectableDays(daysArray);

        }

试试这个！

dateButton.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            Calendar now = Calendar.getInstance();
            now.add(Calendar.DAY_OF_YEAR, 1);
            DatePickerDialog dpd = DatePickerDialog.newInstance(
                    MainActivity.this,
                    now.get(Calendar.YEAR),
                    now.get(Calendar.MONTH),
                    now.get(Calendar.DAY_OF_MONTH)
            );
            dpd.setMinDate(now);
            dpd.setThemeDark(modeDarkDate.isChecked());
            dpd.vibrate(vibrateDate.isChecked());
            dpd.dismissOnPause(dismissDate.isChecked());
            dpd.showYearPickerFirst(showYearFirst.isChecked());
            if (modeCustomAccentDate.isChecked()) {
                dpd.setAccentColor(Color.parseColor("#9C27B0"));
            }
            if(titleDate.isChecked()) {
                dpd.setTitle("DatePicker Title");
            }
            dpd.show(getFragmentManager(), "Datepickerdialog");
        }
    });
}

嘿，我已经完成了关于这个问题的样本，并且能够按照您的预期获得日期选择器一旦检查并让我知道爪哇：

from tkinter import *
import random

class Window(Frame):
    def __init__(self, master=None):
        Frame.__init__(self, master)
        self.master = master
        self.init_window()

    def init_window(self):
        self.pack(fill=BOTH, expand=1)
        testButton = Button(self, text="Press",
                            command=lambda win=self: calc(win))
        testButton.pack()
        self.l1 = Label(text="")
        self.l1.pack()

    def testbutton(self, ans):
        self.l1.configure(text=ans)

def calc(window):  # note window argument added
    list1 = ["a","b","c"]
    index = random.randint(0,2)
    answer = list1[index]
    window.testbutton(answer)

root = Tk()
root.geometry("400x300")
app = Window(root)
root.mainloop()

}

布局：

package yourpackage;
import java.util.Calendar;
import android.app.Activity;
import android.app.DatePickerDialog;
import android.app.Dialog; 
import android.os.Bundle;
import android.view.View;
import android.widget.DatePicker;
import android.widget.TextView;
import android.widget.Toast;

public class MainActivity extends Activity {
private DatePicker datePicker;
private Calendar calendar;
private TextView dateView;
private int year, month, day;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);

    dateView = (TextView) findViewById(R.id.textView3);
    calendar = Calendar.getInstance();
    year = calendar.get(Calendar.YEAR);

    month = calendar.get(Calendar.MONTH);
    day = calendar.get(Calendar.DAY_OF_MONTH);
    showDate(year, month + 1, day);
}

@SuppressWarnings("deprecation")
public void setDate(View view) {
    showDialog(1);
    Toast.makeText(getApplicationContext(), "ca", Toast.LENGTH_SHORT)
            .show();
}

@Override
protected Dialog onCreateDialog(int id) {
    // TODO Auto-generated method stub
    if (id == 1) {
        return new DatePickerDialog(this, myDateListener, year, month,
                day + 1);
    }
    return null;
}

private DatePickerDialog.OnDateSetListener myDateListener = new DatePickerDialog.OnDateSetListener() {
    @Override
    public void onDateSet(DatePicker arg0, int arg1, int arg2, int arg3) {
        // TODO Auto-generated method stub
        // arg1 = year
        // arg2 = month
        // arg3 = day
        showDate(arg1, arg2 + 1, arg3);
    }
};

private void showDate(int year, int month, int day) {
    dateView.setText(new StringBuilder().append(day).append("/")
            .append(month).append("/").append(year));
}

Answer 4

你应该这样做，

Calendar cal = Calendar.getInstance();
            cal.set(Calendar.DAY_OF_MONTH, day + 1);
            cal.set(Calendar.MONTH, month);
            cal.set(Calendar.YEAR, year);

 datePickerDialog.getDatePicker().setMaxDate(maxDate.getTimeInMillis());

这将限制您选择当前日期并让您选择日期从明天开始。

Answer 5

从我记得的这个库的文档中，我相信如果你设置MaterialDateTimePicker的可选日期，那么它会覆盖你为最小和最大日期设置的任何事情。因此，如果您传递一系列日期，则需要包括您的最短和最长日期，以及您希望在其间查看的所有内容。

我无法从明天日期（Material Design Datepicker）设置datepicker开始
