java - 暂停和恢复井字游戏获胜动画

Question

我做了井字游戏并在最后添加了一个动画......每次鞭炮动画从下到上播放时，它都会被按钮重叠（附截图）。我想知道是否有一种简单的方法可以在此处使用线程来停止该过程，然后再使按钮可见，以便鞭炮动画可​​以轻松完成。

这是代码：

for (int[] winningPosition : winningPositions)
            {
                if (gameState[winningPosition[0]] == gameState[winningPosition[1]] && gameState[winningPosition[1]] == gameState[winningPosition[2]] && gameState[winningPosition[0]] != 2) {
                    // Someone has won!
                    gameActive = false;

                    String winner = "";

                    if (activePlayer == 0) {
                        winner = "O";
                    } else {
                        winner = "X";
                    }

                    Button playAgainButton = (Button) findViewById(R.id.playAgainButton);
                    TextView winnerTextView = (TextView) findViewById(R.id.winnerTextView);
                    winnerTextView.setText(winner + " has won!");

                    ImageView firecracker = (ImageView) findViewById(R.id.firecracker);
                    firecracker.setTranslationY(-1000);
                    firecracker.setVisibility(View.VISIBLE);
                    firecracker.animate().translationYBy(-3000).setDuration(1000);
                    firecracker.setTranslationY(4000);
                    playAgainButton.setVisibility(View.VISIBLE);
                    winnerTextView.setVisibility(View.VISIBLE);
                }
            }

再次播放按钮的 Onclick 方法：

public void reset(View view)
    {
        ImageView firecracker = (ImageView) findViewById(R.id.firecracker);
        firecracker.setVisibility(View.INVISIBLE);
        Button playAgainButton = (Button) findViewById(R.id.playAgainButton);
        TextView winnerTextView = (TextView) findViewById(R.id.winnerTextView);
        playAgainButton.setVisibility(View.INVISIBLE);
        winnerTextView.setVisibility(View.INVISIBLE);
}

好吧，如果我正确阅读了这个问题，那么我通常会使用一种方法，那就是创建一个睡眠方法。代码如下：

static void Sleep(int ms)
{
  try {
    Thread.sleep(ms);
   }catch (InterruptedException e) {
    e.printStackTrace();
   }
 }

如果我正确地阅读了这个问题，并且我的解释是你想暂停线程一小段时间然后恢复它。

为了实现这一点，只需在使按钮可见之前调用 Sleep({Time in milliseconds})
