Android活动启动视图和onStart

Question

我正在尝试使用java构建android游戏(这是我第一次这样做，所以我很新)。当用户从主活动中选择他们想玩的游戏时，GamePlay活动类被调用。在这个类中，我试图加载我创建的GameBoard视图，然后运行一个循环，在游戏结束时结束。我已经尝试了一些不同的方法来做到这一点(包括线程)，但我遇到的问题是，在进入循环之前视图不加载。我最终会得到一个黑屏和一个无限循环。有什么建议吗?

注意:单板有点击检测，成功赋值d1和d2。

public class GamePlay extends Activity{
private Player P1;
private Player P2;
private GameBoard board;
private Player turn;
private boolean gameOver = false;
private Thread thread;
//Variables associated with turn
private Dot d1 = null;
private Dot d2 = null;
@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_game_play);
    Bundle extra = getIntent().getExtras();
    String type = extra.getString("GAME_TYPE");
    //Set up appropriate players
    if (type.equals(StartDB.ONE_PLAYER)){
        this.setTitle("One Player Dots And Boxes");
        String P1Name = "Person";
        P1 = new HumanPlayer(Color.RED, P1Name);
        P2 = new AIPlayer(Color.BLUE, "Computer");
    } else {
        this.setTitle("Two Player Dots And Boxes");
        String P1Name = "Player 1";
        String P2Name = "Player 2";
        P1 = new HumanPlayer(Color.RED, P1Name);
        P2 = new HumanPlayer(Color.BLUE, P2Name);
    }
    //Initialize turn to first player
    setTurn(P1);
    //Set up a game board
    board = new GameBoard(this, this);
    setContentView(board);
}

@Override
protected void onStart() {
    super.onStart();
    //Create turn thread and run it
    while (!gameOver){
        while(d2 == null){
            try {
                Thread.sleep(1000);
            } catch (InterruptedException e){
                e.printStackTrace();
            }
        }
        System.out.println("Making a line");
        Line line = new Line(d1, d2);
        board.addLine(line);
        d1 = null;
        d2 = null;
        board.invalidate();
        //This was another attempt made:
        //try {
            //thread = new Thread(new GameLoop(this));
            //thread.start();
            //thread.join();
        //} catch (InterruptedException e) {
            //e.printStackTrace();
        //}
        checkGameOver();
    }
    System.out.println("Game Over");
}

这是一个活动生命周期的图像，以防你以前没有见过它。我发现它很有用:

你能张贴你的游戏板代码吗?错误可能在这里。

也尝试在你的activity_game_play xml中添加你的GameBoard类，就像在这个答案中建议的那样:添加类到xml
