我正在制作一个“西蒙说”游戏作为我在高中的最后一个项目，而且大部分已完成，但我有一个问题。
目前，当我按下按钮时，我正试图让按钮亮起。 但是，它们似乎没有点亮，睡眠功能也不起作用。 它们仅在显示下一个颜色序列的功能亮起时才会改变颜色。
以下是代码：

这是游戏助手类：
package com.gabie212.simonsays;
import java.util.ArrayList;
import java.util.Random;
/**

public class GameManger {
private GameActivity gActivity;
static Random rnd = new Random();
private ArrayList<Integer> randomColors;
public GameManger(GameActivity mA)
{
randomColors = new ArrayList<Integer>();
this.gActivity =mA;
randomColors.add(getColor());
}
public void addColor()
{
randomColors.add(getColor());
}
public int getColor()
{
return rnd.nextInt(4)+1;
}
public ArrayList<Integer> getRandomColors()
{
return randomColors;
}
public boolean check(int num, int index)
{
return(randomColors.get(index)==num);
}
}
enter code here
我有一些问题。
thread.sleep有关。
