ArrayIndexOutOfBoundsException schedule

场景：Timer().schedule ,报ArrayIndexOutOfBoundsException,该如何解决

Timer().schedule ,报ArrayIndexOutOfBoundsException
当触发间隔为200毫秒或大于200毫秒时，是不会报错的，但是如果小一点，比如100，就有可能报错。。。
郁闷啊。。。是不是线程的问题，求解。

Java code


public class Crazy02_layoutActivity extends Activity {
    /** Called when the activity is first created. */
    private int[]colors={R.color.color7,
            R.color.color6,
            R.color.color5,
            R.color.color4,
            R.color.color3,
            R.color.color2,
            R.color.color1
    };
    private int[]names={R.id.view1,
            R.id.view2,
            R.id.view3,
            R.id.view4,
            R.id.view5,
            R.id.view6,
            R.id.view7};
    private TextView[]views=new TextView[7];
    private int currentColor=0;
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        for(int i=0;i<names.length;i++)
        {
            views[i]=(TextView)findViewById(names[i]);
        }
        final Handler handler=new Handler(){

            @Override
            public void handleMessage(Message msg) {
                // TODO Auto-generated method stub
                if(msg.what==0x2211)
                {
                    for(int i=0;i<colors.length-currentColor;i++)
                    {
                        System.out.println("i="+i+",currentColor+i="+(currentColor+i));
                        views[i].setBackgroundResource(colors[currentColor+i]);
                        
                    }
                    System.out.println("first end......");
                    for(int i=0,j=colors.length-currentColor;i<currentColor;i++,j++)
                    {
                        System.out.println("j="+j+",i="+i);
                        views[j].setBackgroundResource(colors[i]);
                    }
                    System.out.println("second end........");
                }
                super.handleMessage(msg);
            }
            
        };
        new Timer().schedule(new TimerTask() {
            
            @Override
            public void run() {
                // TOsdfAuto-generated method stub
                currentColor++;
                if(currentColor==7)
                    currentColor=0;
                Message msg=new Message();
                msg.what=0x2211;
                handler.sendMessage(msg);
            }
        },0,140);
    }
}

------解决方案--------------------

Java code

               
currentColor++;
if(currentColor==7)
   currentColor=0;

------解决方案--------------------
在多线程下,有可能①的时候currentColor是6,到③就变成7了,那样就数组越界了.
应该是异步操作的吧，

------解决方案--------------------
楼上看来把能说的都说了。
if( condition ){ operations }

condition和operations 中间可能被两个不同的线程插进去，结果么你懂的。

------解决方案--------------------
主线程和Timer线程共享currentColor变量,不加锁控制,不出问题才怪.
