分裂數組不工作在android

Question

我分裂一個字符串與中間的一些示例文本。但它不是分裂。請幫我哪裏出了錯

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]); 

輸出

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

Answer 2

我覺得你倒着做。

你想第一次分裂，然後得到一張索引1，再修剪一下，然後設置海峽等於結果：

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"
