【新人贴】android中读取一段文字，如何截取以一定关键字开头和结束的内容？

【专家解说】：字符串截取函数string msg="abcd,efgh"int sign = msg.indexOf(","); int sign1 =msg.indexOf(",", sign+1); int sign2 =msg.indexOf(",", sign1+1); tem = msg.substring(sign2+1, sign2+6); speed = msg.substring(sign2+7, sign2+12); String lat =msg.substring(sign1+1,sign2); String lng =msg.substring(sign+1,sign1);自己琢磨吧，哈哈
