我收到以下错误:
java.lang.StringIndexOutOfBoundsException: length=13243; regionStart=32; regionLength=-39

在下面的代码中,它通常在解析为HttpGesponse给出的HttpGet的XML页面后得到结果:
retry:
{
DefaultHttpClient httpClient = new DefaultHttpClient();
HttpGet httpGet = new HttpGet("http://oxforddictionaries.com/definition/"+query+"?q="+query);
HttpResponse httpResponse = httpClient.execute(httpGet);
HttpEntity httpEntity = httpResponse.getEntity();
String meanings=parser.getResultFromXML(StringUtils.inputStreamToString(httpEntity.getContent()));
if(meanings==null && firstRetry)
{
firstRetry=false;
query = query.substring(0, 1).toUpperCase() + query.substring(1);
break retry;
}
else if(meanings==null && !firstRetry)
return query;
result = query + ":" + meanings;
}
答案 0 :(得分:6)
query = query.substring(0, 1).toUpperCase() + query.substring(1);
我认为此语句会创建使用if(null!=query&&query.length()!=0){query=...}
如果您将字符串length more than 1 in your case
