How to get a random value from a string array in android?

Question

In my values.xml file, I have an array, like this;

    Cow<         


        

Answer 1

String[] array = context.getResources().getStringArray(R.array.animals_array);
String randomStr = array[new Random().nextInt(array.length)];

Hope this helps.

Answer 2

String[] myArrayOfStrings = {"one", "two", "three" } 
Random r = new Random();
String myRandString = r.nextInt(myArrayOfStrings.length );

Answer 3

1. Retrive the Complete String Array from the xml and put it inside an ArrayList using Arrays.asList() method.

2. Use Math.random()*mArr.size() function to get a random number. (mArr is the ArrayList)

3. Then use this random number to get an animal from the ArrayList like

   `myArr.get(myrand);`

4. The reason i suggested the use of ArrayList (ie Collection framework) cause that will give you more flexibility.
