Android get current date and show it in TextView

Question

I do not know what is wrong with code below -

public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    TextView tv = (TextView) findViewById(R.id.textView1);

    String dt;
    Date cal = (Date) Calendar.getInstance().getTime();
    dt = cal.toLocaleString();
    tv.setText(dt.toString());

}

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"/>
