如何擷取系統目前日期時間的方法(2): Calendar dt = Calendar.getInstance();


注意：整個事件程式碼都必須放在
onCreate() 
{  
}
下面
..........................

範例：


import android.view.*;
import android.widget.*;

import java.util.Calendar;
import java.util.Date; 


    // button2事件處理程序
    public void button2_Click(View view) {
        //## date ##############
    	Calendar dt = Calendar.getInstance();
        int thisYear = dt.get(Calendar.YEAR);
        int thisMonth = dt.get(Calendar.MONTH)+1;
        int thisDate = dt.get(Calendar.DAY_OF_MONTH);
        int thisHour = dt.get(Calendar.HOUR_OF_DAY);
        int thisMin = dt.get(Calendar.MINUTE);
        int thisSec = dt.get(Calendar.SECOND);
        
        ///輸出在editText
        EditText ed2 = (EditText) findViewById(R.id.editText2);        
        ed2.setText(Integer.toString(thisYear)+"/" + Integer.toString(thisMonth)+"/" + Integer.toString(thisDate)+" " + Integer.toString(thisHour)+":" + Integer.toString(thisMin)+":" + Integer.toString(thisSec));
           
    }  //end of button2_Click()
