미만 11

Question

내가 최대 및 최소 dates.I는 다음과 같은 짓을 가진 날짜 선택기 대화 상자 만들려고 오전 : 최소 SDK는 8로 설정 하였다

package com.androidexample.datepicker; 

import java.util.Calendar; 
import android.annotation.SuppressLint; 
import android.app.Activity; 
import android.app.DatePickerDialog; 
import android.app.Dialog; 
import android.os.Build; 
import android.os.Bundle; 
import android.view.View; 
import android.view.View.OnClickListener; 
import android.widget.Button; 
import android.widget.DatePicker; 
import android.widget.TextView; 

public class DatePickerExample extends Activity { 

    private TextView Output; 
    private Button changeDate; 

    private int year; 
    private int month; 
    private int day; 
    DatePickerDialog dpd; 
    private static final int MILLIS_IN_SECOND = 1000; 
    private static final int SECONDS_IN_MINUTE = 60; 
    private static final int MINUTES_IN_HOUR = 60; 
    private static final int HOURS_IN_DAY = 24; 
    private static final int DAYS_IN_YEAR = 365; 
    static final int DATE_PICKER_ID = 1111; 

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

     Output = (TextView) findViewById(R.id.Output); 
     changeDate = (Button) findViewById(R.id.changeDate); 

     // Get current date by calender 

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

     // Show current date 

     Output.setText(new StringBuilder() 
       // Month is 0 based, just add 1 
       .append(month + 1).append("-").append(day).append("-") 
       .append(year).append(" ")); 

     // Button listener to show date picker dialog 

     changeDate.setOnClickListener(new OnClickListener() { 

      @Override 
      public void onClick(View v) { 

       // On button click show datepicker dialog 
       showDialog(DATE_PICKER_ID); 

      } 

     }); 
    } 


    @Override 
    protected Dialog onCreateDialog(int id) { 
     switch (id) { 
     case DATE_PICKER_ID: 
      final long MILLISECONDS_IN_YEAR = 
       (long)MILLIS_IN_SECOND * SECONDS_IN_MINUTE * MINUTES_IN_HOUR 
       * HOURS_IN_DAY * DAYS_IN_YEAR; 
      Calendar now = Calendar.getInstance(); 
      int current_year=now.get(Calendar.YEAR); 
      // open datepicker dialog. 
      // set date picker for current date 
      // add pickerListener listner to date picker 
      dpd=new DatePickerDialog(this, pickerListener, year, month,day); 
      if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.HONEYCOMB) { 
       //Calendar.getInstance().get(Calendar.YEAR)-19 
      dpd.getDatePicker().setMaxDate((current_year-16-1970)*MILLISECONDS_IN_YEAR); 
      dpd.getDatePicker().setMinDate((current_year-100-1970)*MILLISECONDS_IN_YEAR); 
      } 


      return dpd; 

      //return new DatePickerDialog(this, pickerListener, year, month,day); 
     } 
     return null; 
    } 

    private DatePickerDialog.OnDateSetListener pickerListener = new DatePickerDialog.OnDateSetListener() { 

     // when dialog box is closed, below method will be called. 
     @Override 
     public void onDateSet(DatePicker view, int selectedYear, 
       int selectedMonth, int selectedDay) { 

      year = selectedYear; 
      month = selectedMonth; 
      day = selectedDay; 

      // Show selected date 
      Output.setText(new StringBuilder().append(month + 1) 
        .append("-").append(day).append("-").append(year) 
        .append(" ")); 

      } 
     }; 

} 

을 그러나 setmaxdate 및 setmindate는 오류를 보여주었습니다. 그래서 최소 sdk 수준을 11로 변경했습니다. 코드가 11 미만의 API 수준에서도 작동하기를 원합니다. API의 최대 및 최소 연도 수를 어떻게 설정합니까? 11 이하 레벨?

Answer 1

당신의 DatePickerDialog 안에이 시도 :

SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd"); 
    Date minDate=new Date("Jan-01-01"); 
    minDate.setYear(Calendar.getInstance().get(Calendar.YEAR)-3914); 
    Date maxDate=new Date("Jan-01-01"); 
    maxDate.setYear(Calendar.getInstance().get(Calendar.YEAR)+6085); 
    dpd.getDatePicker().setMinDate(minDate.getTime()); 
    dpd.getDatePicker().setMaxDate(maxDate.getTime());
