how to draw text with background color using canvas

Question

I have some code where I\'m drawing my text on bitmap (canvas)

canvas.drawTextOnPath(Text, textPath[count], gipa, -10, text);

Please tell me,

Answer 1

I believe this solution is better and more flexible than drawPath.

Use this to calculate the size of the text background:

private @NonNull Rect getTextBackgroundSize(float x, float y, @NonNull String text, @NonNull TextPaint paint) {
    Paint.FontMetrics fontMetrics = paint.getFontMetrics();
    float halfTextLength = paint.measureText(text) / 2 + 5;
    return new Rect((int) (x - halfTextLength), (int) (y + fontMetrics.top), (int) (x + halfTextLength), (int) (y + fontMetrics.bottom));
}

Then draw the background as a Rect:

Rect background = getTextBackgroundSize(x, y, text, textPaint);
canvas.drawRect(background, bkgPaint);
canvas.drawText(text, x, t, textPaint);
