Get time of system

Example to get time (in millisecond and nanosecond) from System, and get instance of Calendar to get current time.


package com.example.androidtime;

import java.util.Calendar;

import android.support.v7.app.ActionBarActivity;
import android.widget.TextView;
import android.os.Bundle;


public class MainActivity extends ActionBarActivity {

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

TextView tim = (TextView)findViewById(R.id.tim);
TextView cal = (TextView)findViewById(R.id.cal);

tim.setText(
"currentTimeMillis: " + System.currentTimeMillis() + "\n" +
"nanoTime" + System.nanoTime() + "\n"
);

Calendar calendar = Calendar.getInstance();
cal.setText(
"YEAR: " + calendar.get(Calendar.YEAR) + "\n" +
"MONTH: " + calendar.get(Calendar.MONTH) + "\n" +
"DAY_OF_MONTH: " + calendar.get(Calendar.DAY_OF_MONTH) + "\n" +
"HOUR_OF_DAY: " + calendar.get(Calendar.HOUR_OF_DAY) + "\n" +
"MINUTE: " + calendar.get(Calendar.MINUTE) + "\n" +
"SECOND: " + calendar.get(Calendar.SECOND) + "\n"
);

}

}
