RichTextLayout使用的问题

可以参考如下代码：

text.addDrawTask((component, canvas) -> {

Paint tempPaint = new Paint();

tempPaint.setTextSize(100);

tempPaint.setColor(Color.RED);

tempPaint.setMultipleLine(true);

tempPaint.setTextAlign(TextAlignment.LEFT);

RichTextBuilder builder = new RichTextBuilder();

builder.mergeForm(new TextForm().setTextSize(60).setTextColor(Color.BLACK.getValue()));

builder.mergeForm(new TextForm().setScaleX(1.5f).setStrikethrough(true));

builder.addText("scaleX1.5 删除线");

builder.revertForm();

builder.mergeForm(new TextForm().setTextBackgroundColor(Color.RED.getValue()).setLineHeight(100));

builder.addText("红色背景色 行高100");

builder.revertForm();

builder.mergeForm(new TextForm().setUnderline(true).setRelativeTextSize(1.5f));

builder.addText("下划线 1.5倍字体大小\n");

builder.revertForm();

builder.mergeForm(new TextForm().setSuperscript(true));

builder.addText("上标");

builder.revertForm();

builder.mergeForm(new TextForm().setSubscript(true));

builder.addText("下标");

builder.revertForm();

builder.addText("正常文字正常文字正常\n文字正常");

final RichText richTextContent = builder.build();

RichTextLayout layout = new RichTextLayout(richTextContent, tempPaint,

new Rect(0, 0, 1000, 1000), 1000);

layout.drawText(canvas);

});
