using spannable to seperate words in a String


I DON'T WANT SPAN ON MY SPACES

I have a string, for example:

String items = " flowers chocolates candles ";

What I need to do is print this string like this:

enter image description here

Can I do this using spannable in Java? If yes, how ?

I have this RoundedBackgroundSpan class:

public class RoundedBackgroundSpan extends ReplacementSpan {

    private static final int CORNER_RADIUS = 8;
    private int backgroundColor = 0;
    private int textColor = 0;

    public RoundedBackgroundSpan(Context context) {
        super();
        backgroundColor = context.getResources().getColor(R.color.colorPrimary);
        textColor = context.getResources().getColor(R.color.white);
    }

    @Override
    public void draw(Canvas canvas, CharSequence text, int start, int end, float x, int top, int y, int bottom, Paint paint) {
        RectF rect = new RectF(x, top, x + measureText(paint, text, start, end), bottom - 2);
        paint.setColor(backgroundColor);
        canvas.drawRoundRect(rect, CORNER_RADIUS, CORNER_RADIUS, paint);
        paint.setColor(textColor);
        canvas.drawText(text, start, end, x, y, paint);
    }

    @Override
    public int getSize(Paint paint, CharSequence text, int start, int end, Paint.FontMetricsInt fm) {
        return Math.round(paint.measureText(text, start, end));
    }

    private float measureText(Paint paint, CharSequence text, int start, int end) {
        return paint.measureText(text, start, end);
    }
}

Solution

  • use this function:

    private Spannable spanWords(String message) {
        int start = 0;
        String[] words = message.split(" ");
        Spannable spannable = new SpannableString(message);
        for (String word : words) {
            spannable.setSpan(new RoundedBackgroundSpan(getContext()), start, (start + word.length()), Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);
    
            start += word.length() + 1;
        }
        return spannable;
    }
