Android 日期选择器禁用 2014 年 12 月 1 日之前的所有日期

Question

我已经在 android 中成功实现了 datepicker 我的问题是我想在 2014 年 12 月 1 日之前禁用 datepicker 中的所有日期如何做到这一点，我尝试寻找示例但他们都提供了示例禁用今天日期之前的日期

我还没有实现任何代码来禁用以前的日期任何工作示例都会很好提前致谢

这是我的代码

import java.util.Calendar;

import android.app.DatePickerDialog;

public class MainActivity extends ActionBarActivity {

     /** Private members of the class */
    private TextView pDisplayDate;

    private int pMonth;
    private int pDay;
    /** This integer will uniquely define the dialog to be used for displaying date picker.*/
    static final int DATE_DIALOG_ID = 0;

    /** Callback received when the user "picks" a date in the dialog */
    private DatePickerDialog.OnDateSetListener pDateSetListener =
            new DatePickerDialog.OnDateSetListener() {

                public void onDateSet(DatePicker view, int year, 
                                      int monthOfYear, int dayOfMonth) {
                    pYear = year;
                    pMonth = monthOfYear + 1;
                    pDay = dayOfMonth;

//                    if (pMonth<10)
//                         pMonth='0'+pMonth;

                    updateDisplay();
                    displayToast();
                }

            formattedMonth = "0" + pMonth;
        }
        if(pDay < 10){

            formattedDayOfMonth = "0" + pDay;
        }
       // searchText.setText(formattedDayOfMonth + "/" + formattedMonth + "/" + year);


        pDisplayDate.setText(
            new StringBuilder()
//                    // Month is 0 based so add 1
                    .append(pYear).append("-")
                    .append(formattedMonth).append("-")
                    .append(formattedDayOfMonth).append(" "));
    }

    /** Displays a notification when the date is updated */
    private void displayToast() {
        Toast.makeText(this, new StringBuilder().append("Date choosen is ").append(pDisplayDate.getText()),  Toast.LENGTH_SHORT).show();

    }

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        /** Capture our View elements */
        pDisplayDate = (TextView) findViewById(R.id.displayDate);
        pPickDate = (Button) findViewById(R.id.pickDate);

        /** Listener for click event of the button */
        pPickDate.setOnClickListener(new View.OnClickListener() {
            @SuppressWarnings("deprecation")
            public void onClick(View v) {
                showDialog(DATE_DIALOG_ID);
            }
        });

        /** Get the current date */
        final Calendar cal = Calendar.getInstance();
        pYear = cal.get(Calendar.YEAR);
        pMonth = cal.get(Calendar.MONTH);
        pDay = cal.get(Calendar.DAY_OF_MONTH);

        /** Display the current date in the TextView */
        updateDisplay();
    }

    /** Create a new dialog for date picker */
    @Override
    protected Dialog onCreateDialog(int id) {
        switch (id) {
        case DATE_DIALOG_ID:
            return new DatePickerDialog(this, 
                        pDateSetListener,
                        pYear, pMonth, pDay);
        }
        return null;
    }
}

Answer 1

像这样设置最大日期：

protected Dialog onCreateDialog(int id) {
        switch (id) {
        case DATE_DIALOG_ID:
DatePickerDialog dialog = new DatePickerDialog(mContext,
                        datePickerListener, myCalendar.get(Calendar.YEAR),
                        myCalendar.get(Calendar.MONTH), myCalendar
                                .get(Calendar.DAY_OF_MONTH));
             dialog.getDatePicker().setMaxDate(new Date().getTime());
                    dialog.show();
        }
        return null;
    }

完成了，这可能对可以相应地使用 if 条件的人有所帮助
