Try this

private void drawRectText(String text, Canvas canvas, Rect r) {

    textPaint.setTextSize(20);
    textPaint.setTextAlign(Align.CENTER);
    int width = r.width();

    int numOfChars = textPaint.breakText(text,true,width,null);
    int start = (text.length()-numOfChars)/2;
    canvas.drawText(text,start,start+numOfChars,r.exactCenterX(),r.exactCenterY(),textPaint);
}

this function worked for me.

private void drawDigit(Canvas canvas, int textSize,  float cX, float cY, int color, String text) {
        Paint tempTextPaint = new Paint();
        tempTextPaint.setAntiAlias(true);
        tempTextPaint.setStyle(Paint.Style.FILL);

        tempTextPaint.setColor(color); 
        tempTextPaint.setTextSize(textSize); 

        float textWidth = tempTextPaint.measureText(text);
        //if cX and cY are the origin coordinates of the your rectangle 
        //cX-(textWidth/2) = The x-coordinate of the origin of the text being drawn 
        //cY+(textSize/2) =  The y-coordinate of the origin of the text being drawn 

        canvas.drawText(text, cX-(textWidth/2), cY+(textSize/2), tempTextPaint);
    }
