要求：我想实现图片的键盘左右移动，而且泡泡垂直上升碰到其他泡泡如果是三个不同颜色的则消掉这三个不是则停止上升，泡泡碰到图片就停止，如果有泡泡龙JAVA EE的源代码发来参考的话感激不尽

在网上可以搜到手机键盘码的,手机上的每一个键有一个数字码,然后你判断一下:
如果你按A(这个数字你自己选):
if（e.keycode==58）花括号//这里的A的数字码可能不是58,我只是随便找了个数字代替一下的
获取你的图片在屏幕上的位置,然后用++，--,或者你需要进行位置的距离来进行计算就可以了
花括号
而泡泡上升碰到其他的泡泡,这个就是碰撞检测了,碰撞检测我只知道一点点,你可以查查资料看看，网上可以搜到的。
然后根据泡泡的颜色来进行相应的操作就可以了。
泡泡的上升则不断的增加泡泡的竖直方向上的位置就可以了。
对于泡泡上升位置的停止,你可以定义一个常量，如果三个泡泡颜色不一样,就给这个常量一个新值,然后在一个判断里break一下就可以了。
泡泡的上升最好用for，范围在屏幕底层的原点到屏幕竖直方向上的最高点。
你可以根据这个思路,然后自己调整修改。
感觉进入了一个误区，就是用图片进行判断，
其实在底层用的还是一个数组表示，或者用其他数据存储泡泡对象，判断大小，颜色，这些都是对象的属性，
每一次一个泡泡的运动到最后能影响的范围，做一个遍历的判断，那就是规则，
