Multiple dot span to one date

[mimakopanja]

I have database with lists of tasks, i need to add multiple dot spans to one date with different color (color depends on the list category - study, work...)

Spans are adding but they are overlapping each other. Can anyone please help?

Hi. How you solve it?

I've had almost the same problem, so I've written this class for single color dots.

I hope this is helps anyone in the future:

import android.graphics.Canvas;
import android.graphics.Paint;
import android.text.style.LineBackgroundSpan;

public class MultiDotSpan implements LineBackgroundSpan {
    private static final float DEFAULT_RADIUS = 3;
    private static final float DEFAULT_PADDING = 15;

    private final float radius;
    private final int color;
    private final int amount;

    public MultiDotSpan() {
        this.radius = DEFAULT_RADIUS;
        this.color = 0;
        this.amount = 1;
    }

    public MultiDotSpan(float radius) {
        this(radius, 0);
    }

    public MultiDotSpan(float radius, int color) {
        this(radius, color, 1);
    }

    public MultiDotSpan(float radius, int color, int amount) {
        this.radius = radius;
        this.color = color;
        this.amount = amount;
    }

    @Override
    public void drawBackground(Canvas canvas, Paint paint, int left, int right, int top, int baseline, int bottom, CharSequence charSequence, int start, int end, int lineNum) {
        int oldColor = paint.getColor();
        if (color != 0) {
            paint.setColor(color);
        }
        float center = (left + right) / 2f;
        for (int i = 0; i < amount; i++) {
            float x = center + (i - (amount - 1) / 2f) * DEFAULT_PADDING;
            canvas.drawCircle(x, bottom + radius, radius, paint);
        }
        paint.setColor(oldColor);
    }
}
