Android: changing text color in ListView based on String value

Perhaps it has been said a lot of times, and I'm sorry, but searching all the web wouldn't help me to find a solution. I have to make a ListView from an array of String, but I want the color of text changing for each line, for example if the string contains "yellow" word the color of the text would be yellow. How can I set a thing like this?

You can implement a simple adapter like this and use it to fill the ListView

    public class MySimpleStringAdapter extends ArrayAdapter<String> {


        public MySimpleStringAdapter (Context context, int textViewResourceId, List<String> objects) {
            super(context, textViewResourceId, objects);
        }

        @Override
        public View getView(int position, View convertView, ViewGroup parent) {
         String myString = getItem(position);
            //check your string
            //Change the color as you want
            //((TextView)convertView).setTextColor();
        }
    }

On the main class 

MySimpleStringAdapter  mySimpleNewAdapter = new MySimpleStringAdapter (context,textViewResourceId,stringList);
listView.setAdapter(mySimpleNewAdapter );

Create a HashMap with key as color word and value as integer.

Sample code:

    HashMap<String, Integer> colorCode = new HashMap<String, Integer>();
    colorCode.put("Red", Color.parseColor("Red"));
    // put all pre-defined color in map

    tv.setTextColor(colorCode.get("your color word"));
