多个LinearLayout如何实现点击选中效果？

就是用LinearLayout 写的一列按钮，默认给个颜色值选中第一个，当点击第二个的时候选中第二个，同时恢复第一个。以此类推！

什么一个LinearLayout 变量，每次选中 一个LinearLayout ，就把这个LinearLayout 赋值给那个变量，点击下一个时，先判断这个变量是否为null，如果不是，就恢复它的样子

谢谢！我感觉您说的应该行得通！我先试试！

类似于这样实现一个Checkable的Button，然后选中一个时手动设置另外的几个，不过你如果不想手动设置的话可以重写LinearLayout, 在LinearLayout里面监听每个子View的点击点击其中一个时将其他的恢复。
