字符串的拆分可以利用android的 split 来简单实现
具体看如下代码：
String s3 = "Real-How-To";
String [] temp = null;
temp = s3.split("-");
etShow.setText(temp[] + " linc " + temp[]);
但是要注意的是，如果使用"."、"|"、"^"等字符做分隔符时，要写成s3.split("\\^")的格式，
否则不能拆分。
参见http://www.rgagnon.com/javadetails/java-0438.html中
split() is based on regex expression, a special attention is needed with some characters which have a special meaning in a regex expression.
For example :
String s3 = "Real.How.To";
...
temp = s3.split("\\.");
or
String s3 = "Real|How|To";
...
temp = s3.split("\\|");
