Question

我正在分割一个字符串，中间有一些示例文本。但它并没有分裂。请帮助我出错的地方

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]);

<强>输出

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

Answer 2

我认为你是倒退了。

你想首先拆分，然后在索引1处得到一块，然后修剪，然后将str设置为等于结果：

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"

拆分数组在android中不起作用
