如何在字符串数组项元素内搜索特定文本?以下是xml文件的示例.字符串数组名称是android.我在字符串数组中有一些项.现在,我想搜索软件"一词.请告诉我该怎么做?
How to search for a specific text inside a string-array item element? The following is an example of the xml file. The string-array name is android. I have some items inside the string-array. Now I want to do a search for the word "software". Please tell me how to do that?
<?xml version="1.0" encoding="utf-8"?><resources> <string-array name="android"> <item>Android is a software stack for mobile devices that includes an operating system, middleware and key applications.</item> <item>Google Inc. purchased the initial developer of the software, Android Inc., in 2005..</item> </string-array>推荐答案
我假设您想在代码中执行此操作. api中没有任何东西可以对整个String数组进行文本匹配;您需要一次完成一项操作:
I assume that you want to do this in code. There's nothing in the api to do text matching on an entire String array; you need to do it one element at a time:
String[] androidStrings = getResources().getStringArray(R.array.android); for (String s : androidStrings) { int i = s.indexOf("software"); if (i >= 0) { // found a match to "software" at offset i } }当然,您可以使用Matcher和Pattern,或者如果您想知道匹配项在数组中的位置,可以使用索引对数组进行迭代.但这是一般的方法.
Of course, you could use a Matcher and Pattern, or you could iterate through the array with an index if you wanted to know the position in the array of a match. But this is the general approach.
