如果想用android stdio做一个飞行器游戏需要怎么做是否可以给出简单代码

要使用Android Studio制作飞行器游戏，需要以下步骤：

1. 创建一个新的Android Studio项目。
2. 添加一个SurfaceView作为游戏画布。
3. 创建一个游戏循环，用于更新和渲染游戏画面。
4. 添加飞行器和障碍物的图像资源。
5. 实现飞行器和障碍物的移动和碰撞检测逻辑。
6. 添加触摸事件处理，用于控制飞行器的移动。
7. 添加音效和得分系统。

以下是一个简单的示例代码，用于创建一个基本的飞行器游戏：

public class MainActivity extends AppCompatActivity implements SurfaceHolder.Callback, Runnable {

    private SurfaceView surfaceView;
    private SurfaceHolder holder;
    private boolean running = false;

    private int screenWidth;
    private int screenHeight;

    private Bitmap playerBitmap;
    private Bitmap obstacleBitmap;

    private int playerX;
    private int playerY;
    private int obstacleX;
    private int obstacleY;

    private int score = 0;

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

        surfaceView = (SurfaceView) findViewById(R.id.surfaceView);
        holder = surfaceView.getHolder();
        holder.addCallback(this);

        DisplayMetrics metrics = new DisplayMetrics();
        getWindowManager().getDefaultDisplay().getMetrics(metrics);
        screenWidth = metrics.widthPixels;
        screenHeight = metrics.heightPixels;

        playerBitmap = BitmapFactory.decodeResource(getResources(), R.drawable.player);
        obstacleBitmap = BitmapFactory.decodeResource(getResources(), R.drawable.obstacle);

        playerX = screenWidth / 2 - playerBitmap.getWidth() / 2;
        playerY = screenHeight - playerBitmap.getHeight();

        obstacleX = screenWidth / 2 - obstacleBitmap.getWidth() / 2;
        obstacleY = 0;
    }

    @Override
    public void surfaceCreated(SurfaceHolder surfaceHolder) {
        running = true;
        new Thread(this).start();
    }

    @Override
    public void surfaceChanged(SurfaceHolder surfaceHolder, int i, int i1, int i2) {

    }

    @Override
    public void surfaceDestroyed(SurfaceHolder surfaceHolder) {
        running = false;
    }

    @Override
    public void run() {
        while (running) {
            Canvas canvas = holder.lockCanvas();
            if (canvas != null) {
                update();
                draw(canvas);
                holder.unlockCanvasAndPost(canvas);
            }
            try {
                Thread.sleep(16);
            } catch (InterruptedException e) {
                e.printStackTrace();
            }
        }
    }

    private void update() {
        obstacleY += 10;
        if (obstacleY > screenHeight) {
            obstacleY = 0;
            obstacleX = (int) (Math.random() * (screenWidth - obstacleBitmap.getWidth()));
            score++;
        }
        if (playerX + playerBitmap.getWidth() > obstacleX && playerX < obstacleX + obstacleBitmap.getWidth() && playerY + playerBitmap.getHeight() > obstacleY && playerY < obstacleY + obstacleBitmap.getHeight()) {
            // collision detected
            score = 0;
        }
    }

    private void draw(Canvas canvas) {
        canvas.drawColor(Color.WHITE);
        canvas.drawBitmap(playerBitmap, playerX, playerY, null);
        canvas.drawBitmap(obstacleBitmap, obstacleX, obstacleY, null);

        Paint paint = new Paint();
        paint.setColor(Color.BLACK);
        paint.setTextSize(50);
        canvas.drawText("Score: " + score, 50, 50, paint);
    }

    @Override
    public boolean onTouchEvent(MotionEvent event) {
        if (event.getAction() == MotionEvent.ACTION_DOWN) {
            if (event.getX() < screenWidth / 2) {
                playerX -= 50;
            } else {
                playerX += 50;
            }
        }
        return super.onTouchEvent(event);
    }
}

这个代码实现了一个简单的飞行器游戏，飞行器可以通过触摸屏幕左右移动，避开障碍物并获得得分。代码中使用了SurfaceView作为游戏画布，使用了游戏循环来更新和渲染游戏画面，实现了飞行器和障碍物的移动和碰撞检测逻辑。
