Answer 1

SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd");    
String currentDateandTime = sdf.format(new Date());    
tv.setText(currentDateandTime);

Answer 2

Consider using a TextClock as it will handle updates for you. For more info here is the documentation Docs . AnalogClock and DigitalClock can also be useful if your objective is just to display current time and date

 <TextClock
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:textSize="30sp"
    android:format24Hour="MMM,yyyy\n\thh:mm"/>

Answer 3

Calendar c = Calendar.getInstance();
SimpleDateFormat df = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
String formattedDate = df.format(c.getTime());
System.out.println("Currrent Date Time : "+formattedDate);

Answer 4

use this code:

tvDisplayDate = (TextView) findViewById(R.id.tvDate);


    final Calendar c = Calendar.getInstance();
    yy = c.get(Calendar.YEAR);
    mm = c.get(Calendar.MONTH);
    dd = c.get(Calendar.DAY_OF_MONTH);

    // set current date into textview
    tvDisplayDate.setText(new StringBuilder()
    // Month is 0 based, just add 1
            .append(yy).append(" ").append("-").append(mm + 1).append("-")
            .append(dd));
