Question

I have this code which searches a string array and returns the result if the input string matches the 1st characters of a string:

for (int i = 0; i < countryCode.length; i++) {
            if (textlength <= countryCode[i].length()) {
                if (etsearch
                        .getText()
                        .toString()
                        .equalsIgnoreCase(
                                (String) countryCode[i].subSequence(0,
                                        textlength))) {
                    text_sort.add(countryCode[i]);
                    image_sort.add(flag[i]);
                    condition_sort.add(condition[i]);
                }
            }
        }

But i want to get those string also where the input string matches not only in the first characters but also any where in the string? How to do this?

You have three way to search if an string contain substring or not:

String string = "Test, I am Adam";
// Anywhere in string
b = string.indexOf("I am") > 0;         // true if contains 

// Anywhere in string
b = string.matches("(?i).*i am.*");     // true if contains but ignore case

// Anywhere in string
b = string.contains("AA")  ;             // true if contains but ignore case
