Can someone please help me with the issue.I want my activity as full screen and want to remove title from the screen.I have tried several ways but not able to remove it.

Activity Code :

public class welcomepage extends Activity {
    private Button btn;
    EditText userName,passWord;
    DatabaseHandler dbHandler;
    Context ctx =this;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        //Remove title bar
        this.requestWindowFeature(Window.FEATURE_NO_TITLE);
        setContentView(R.layout.activity_welcomepage);
   }
}

And Activity.xml 

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:paddingBottom="@dimen/activity_vertical_margin"
    android:paddingLeft="@dimen/activity_horizontal_margin"
    android:paddingRight="@dimen/activity_horizontal_margin"
    android:paddingTop="@dimen/activity_vertical_margin"
    android:background="@drawable/pic1"
    app:layout_behavior="@string/appbar_scrolling_view_behavior"
    tools:context="com.edkul.vimal.edkul.welcomepage">

</RelativeLayout>

Try this:

this.getSupportActionBar().hide();

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    try
    {
        this.getSupportActionBar().hide();
    }
    catch (NullPointerException e){}

    setContentView(R.layout.activity_main);
}

For Kotlin you only need this line:

this.actionBar?.hide()

You may use it before setting your content for example:

super.onCreate(savedInstanceState)

//this line is important
this.actionBar?.hide()

setContent {
    Box(Modifier.fillMaxSize()) {
    .
    .
    .

You do not need any other changes on XML
