Preface

The DayOfYearActivity class


The DayOfYearActivity activity is a very simple class that uses Java's default java.util.Calendar instance to calculate how many days have passed and how many days are remaining until the end of the year:

import android.app.Activity;
import android.os.Bundle;
import android.widget.TextView;
import java.util.Calendar;

public class DayOfYearActivity extends Activity 
{
  @Override
  protected void onCreate(Bundle savedInstanceState) 
  {
  super.onCreate(savedInstanceState);         
  setContentView(R.layout.activity_day_of_year);         
  Calendar calendar = Calendar.getInstance();         
  String dayOfYearDesc = getString(R.string.day_of_year_card_desc,                   
    calendar.get(Calendar.DAY_OF_YEAR),  
    calendar.getActualMaximum(Calendar.DAY_OF_YEAR) - 
    calendar.get(Calendar.DAY_OF_YEAR));         
  TextView desc = (TextView) findViewById(R.id.day_of_year_desc);         
  desc.setText(dayOfYearDesc);     
  } 
}
