Question

我使用了一个contentView“gameView”，它扩展了一个SurfaceView，我使用一个线程为我的游戏设置一个永久循环，我的onCreate（）方法是

public class mainclass extends Activity {
GameView game;
@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    requestWindowFeature(Window.FEATURE_NO_TITLE);
    setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE);
    getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, 
            WindowManager.LayoutParams.FLAG_FULLSCREEN);
    game = new GameView(this);
    setContentView(game);
}

崩溃logcat是

注意：此次崩溃发生在第二次，但第三次崩溃，第四次崩溃，五次正常等等。

Answer 1

在你的GameView的surfaceCreated方法中，你需要重新创建游戏线程，因为你可能会在你的surfaceDestroyed方法中使用gamethread.join（）让它死掉。像这样：

@Override
public void surfaceCreated(SurfaceHolder holder) {
    if (gamethread.getState() == Thread.State.TERMINATED) {
        gamethread = new GameThread(getHolder(), this);
        gamethread.setRunning(true);
        gamethread.start();
    } else if (gamethread.getState() == Thread.State.NEW) {
        gamethread.setRunning(true);
        gamethread.start();
    }
}

@dymmeh：我的代码是

@Override
          public void surfaceDestroyed(SurfaceHolder holder) 
        {
            boolean retry = true;
            mythread.setRunning(false);
            while (retry) {

                   try {
                            mythread.join();
                            retry = false;
                       } catch (InterruptedException e) {
                   }
            }
     }

那是什么导致了你所说的，我用

替换了它

    @Override
          public void surfaceDestroyed(SurfaceHolder holder) 
        {
            mythread.setRunning(false);
            System.exit(0);
        }

现在，一切进展顺利，谢谢！
