Searching for a string in a String-Array item element

Question

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

Answer 1

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
    }
}

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.

Answer 2

This method has better performances:

String[] androidStrings = getResources().getStringArray(R.array.android);   
if (Arrays.asList(androidStrings).contains("software") {
    // found a match to "software"           
}

Arrays.asList().contains() is faster than using a for loop.
