我遇到以下崩溃

java.lang.RuntimeException: Failure delivering result ResultInfo{who=null, request=1010, result=-1, data=Intent {  launchParam=MultiScreenLaunchParams { mDisplayId=0 mFlags=0 }(has extras) }} to activity {com.forsale.forsale/com.forsale.forsale.view.ItemsActivity}: java.util.regex.PatternSyntaxException: Syntax error in regexp pattern near index 1

我的代码如下：

String[] items = attributes.split("},");

Answer 1

split函数将正则表达式模式作为参数（因为它写在错误中）

}是正则表达式的特殊字符

尝试那样逃脱

   String[] items = attributes.split("\\},");

Java拆分字符串不起作用
