Android: Compare words based on position and using spannable

Question

I have a code here that changes the color of a word from a sentence. Violet if the word found is of the same position. Yellow if the answer contains a word but of a different position and red if the word is not found.

My problem right now is that the color changes to violet even though the word is of different position. I also tried to use splitInput[i].contains(splitAnswer[i]) to change the word to yellow but i got a repeated words for example "It was a a sample sample sentence sentence".

        String answer = "This is a sample sentence"
        String userInput = "It was a sample sentence"
        boolean wordFound = false;
        String[] splitAnswer = answer.split(" ");
        String[] splitInput = userInput.split(" ");

        for (int i=0; i<splitAnswer.length;i++) 
        {
            for (int j=0;j<splitInput.length;j++) 
            {
                if(splitInput[i].equalsIgnoreCase(splitAnswer[i])) 
                {
                wordFound = true;
                //color the word to violet
                }
            {
            if(wordFound==false)
            {
            //color the word to red 
            }
             //display the sentence
             wordFound == false; 
        }

String answer = "This is a sample sentence";
        String userInput = "It was a sample sentence";
        boolean wordFound = false;
        String[] splitAnswer = answer.split(" ");
        String[] splitInput = userInput.split(" ");

         for (int i=0; i<splitAnswer.length;i++) 
         {

        if (splitInput[i].equalsIgnoreCase(splitAnswer[i]))
        {

            System.out.println ("Word found");
        }
        else if(!wordFound)
        {

            System.out.println ("Word Not found");
        }
    }
