2023-08-21android canvas绘图

1绘制直线

  canvas.drawLine(0 + marginLeft, marginTop, 0 + marginLeft, height - marginTop, paint);

2在表格中绘制文字剧中，主要逻辑在于表格x轴坐标+(表格-文字宽度)/2

   paint.setStrokeWidth(1);
        paint.setTypeface(Typeface.DEFAULT);
        paint.setTextSize(textSize);
        //绘制word
        float wordWidth = paint.measureText(word);
        float wordX = (hundredMargin - wordWidth) / 2;

        float baseLineY = sinagelRowHeight / 2 + Math.abs(paint.ascent() + paint.descent()) / 2 + marginTop;
        canvas.drawText(word, wordX + thirtyTwoMargin + marginLeft, baseLineY, paint);
