adt版本升级后，不支持switch...case语句的解决办法

在eclipse中导入工程后 出现下图的错误：

上图中的代码出现这样的情况，是因为R.java文件中定义属性的方式为：public static int xxx = 0x7f0a0003; 而自从adt14开始，R.java文件定义属性的方式有发生了变化：public static final int xxx =0x7f0a0003; 所以使用switch...case语句来定位id这样的代码将不再编译，解决办法是选中switch这个keyword,按ctrl + 1将代码块转换为if...else，问题解决！

google官方给出的解释是：

In a regular Android project, constants in the resource R class are declared like this:

publicstaticfinalintmain=0x7f030004;

However, as of ADT 14, in a library project, they will be declared like this:

public static int main=0x7f030004;

The solution for this is simple: Convert the switch statement into an if-else statement. Fortunately, this is very easy in Eclipse. Just place the caret on the switch keyword, and press Ctrl-1 (or Cmd-1 on Mac):
