Android Studio game not using entire android display

Question

Upon starting my game, the game does not utilise the entire android screen. This only happens with the game itself, shown by the image as the user is unable to reach the bottom of the screen. Have tried to find a solution however all attempts I have tried seems not to work. Unsure which code to supply, and therefore do not want to provide a large amount of code. Let me know which code to post. Any help would be appreciated.

Image of game

package com.example.spaceattack;

import androidx.appcompat.app.AppCompatActivity;

import android.os.Bundle;
import android.os.Handler;

import java.util.Timer;
import java.util.TimerTask;

public class MainActivity extends AppCompatActivity
{
    private SpaceShipView gameView;
    private Handler handler = new Handler();
    private final static long Interval = 30;

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

        gameView = new SpaceShipView(this);
        setContentView(gameView);

        Timer timer = new Timer();
        timer.schedule(new TimerTask() {
            @Override
            public void run()
            {
                handler.post(new Runnable() {
                    @Override
                    public void run()
                    {
                        gameView.invalidate();

                    }
                });
            }
        }, 0, Interval);

    }
}

have a look at below question. You have to flag your activity as a full screen activity. https://stackoverflow.com/questions/2868047/fullscreen-activity-in-android — Deshan, Apr 12 '20 at 04:25

You need to hide the status/system by getting the window of your app and set below flags:

More from Documentation

// hide status bar
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.JELLY_BEAN) {
    getWindow().getDecorView().setSystemUiVisibility(View.SYSTEM_UI_FLAG_FULLSCREEN);

} else {
    getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN);
}

So in your code:

public class MainActivity extends AppCompatActivity
{
    private SpaceShipView gameView;
    private Handler handler = new Handler();
    private final static long Interval = 30;

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

        gameView = new SpaceShipView(this);
        setContentView(gameView);

        // hide status bar
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.JELLY_BEAN) {
            mUiOptions = View.SYSTEM_UI_FLAG_FULLSCREEN;
            getWindow().getDecorView().setSystemUiVisibility(mUiOptions);
        } else {
            getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN);
        }

        Timer timer = new Timer();
        timer.schedule(new TimerTask() {
            @Override
            public void run()
            {
                handler.post(new Runnable() {
                    @Override
                    public void run()
                    {
                        gameView.invalidate();

                    }
                });
            }
        }, 0, Interval);

    }
}

getWindow() is this a function I would need to add to my code? – Ryan Reynolds Apr 06 '20 at 15:11
@RyanReynolds yes it's a function of the parent `Activity` class that you can call in your custom AppCompatActivity` `onCreate()` method – Zain Apr 06 '20 at 15:15
Provided an edit of the code showing the onCreate() function in my main activity. From this how would I implement the code, would I need to write getWindow() function within this onCreate? – Ryan Reynolds Apr 06 '20 at 15:24
@RyanReynolds no just copy and paste the provided code withing the activity onCreate() method – Zain Apr 06 '20 at 15:28
@RyanReynolds please put my code in your onCreate() method, I updated the answer – Zain Apr 06 '20 at 15:39
Issue still seems to be the same. User only seems to go similar to the image in the question. – Ryan Reynolds Apr 06 '20 at 15:41
Could post my entire code which you could look over if it would help. – Ryan Reynolds Apr 06 '20 at 15:45
