分裂数组不工作在android

Question

我分裂一个字符串与中间的一些示例文本。但它不是分裂。请帮我哪里出了错

String[] str; 

parts[1] = "loopstWatch out this is testingloopstThis makes the difference"; 
str = parts[1].trim().split("loopst"); 

Answer 1

String[] arr; 
       arr = "loopstWatch out this is testingloopstThis makes the difference".trim().split("loopst"); 
       Log.e("Data arr[0]",":"+arr[0]); 
       Log.e("Data arr[1]",":"+arr[1]); 
       Log.e("Data arr[2]",":"+arr[2]); 

输出

arr[0] :"" 
arr[1] :"Watch out this is testing" 
arr[2] :"This makes the difference" 

Answer 2

我觉得你倒着做。

你想第一次分裂，然后得到一张索引1，再修剪一下，然后设置海峡等于结果：

String s = "loopstWatch out this is testingloopstThis makes the difference"; 
String str = s.split("loopst")[1].trim(); 

// str should be equal to "Watch out this is testing"
