Android 拆分字符串 [英] Android Split string

问题描述

我有一个名为 CurrentString 的字符串，它的形式是这样的水果:味道不错".
我想使用 : 作为分隔符来拆分 CurrentString.
这样，"Fruit" 这个词就会被拆分成它自己的字符串，而 "they taste good" 将是另一个字符串.
然后我只想使用 2 个不同的 TextViews 的 SetText() 来显示该字符串.

I have a string called CurrentString and is in the form of something like this "Fruit: they taste good".
I would like to split up the CurrentString using the : as the delimiter.
So that way the word "Fruit" will be split into its own string and "they taste good" will be another string.
And then i would simply like to use SetText() of 2 different TextViews to display that string.

解决这个问题的最佳方法是什么?

What would be the best way to approach this?

推荐答案

String currentString = "Fruit: they taste good";
String[] separated = currentString.split(":");
separated[0]; // this will contain "Fruit"
separated[1]; // this will contain " they taste good"

您可能想要删除第二个字符串的空格:

You may want to remove the space to the second String:

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

如果你想用像点(.)这样的特殊字符来分割字符串，你应该在点之前使用转义字符

If you want to split the string with a special character like dot(.) you should use escape character before the dot

示例:

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.例如，您可以使用 StringTokenizer 类(来自 java.util):

There are other ways to do it. For instance, you can use the StringTokenizer class (from 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
