android 逗号分割字符串,Android拆分字符串

String currentString = "Fruit: they taste good";

String[] separated = currentString.split(":");

separated[0]; // this will contain "Fruit"

separated[1]; // this will contain " they taste good"

您可能要删除第二个字符串的空格：

separated[1] = separated[1].trim();

如果要使用特殊字符(例如dot(。))分割字符串，则应在点之前使用转义字符\

例：

String currentString = "Fruit: they taste good.very nice actually";

String[] separated = currentString.split("\\.");

separated[0]; // this will contain "Fruit: they taste good"

separated[1]; // this will contain "very nice actually"

还有其他方法可以做到这一点。例如，您可以使用StringTokenizer类(来自java.util)：

StringTokenizer tokens = new StringTokenizer(currentString, ":");

String first = tokens.nextToken();// this will contain "Fruit"

String second = tokens.nextToken();// this will contain " they taste good"

// in the case above I assumed the string has always that syntax (foo: bar)

// but you may want to check if there are tokens or not using the hasMoreTokens method
