篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了canvas实现文字分行相关的知识，希望对你有一定的参考价值。

//paint.setColor(Color.WHITE);//paint.setTextSize(TEXT_SIZE*density);//paint.setAlpha(0x40);//paint.setTypeface(Typeface.create("System",Typeface.BOLD));//canvas.drawText("将大象单车上的二维码放入框内\n获取开锁密码", frame.left, 、、//(float(frame.bottom + (float)TEXT_PADDING_TOP *density), paint);

将原来代码中的文字显示改为以下代码?

?TextPaint textPaint =new TextPaint();

?textPaint.setARGB(0xFF,255,251,240);

?textPaint.setTextSize(TEXT_SIZE * density);

?textPaint.setAntiAlias(true);

StaticLayout layout = new StaticLayout("将大象单车上的二维码放入框内\r\n获取开锁密码", textPaint,480,Layout.Alignment.ALIGN_CENTER, 1.0F, 0.0F, true);

canvas.save();

canvas.translate(frame.left,frame.bottom + (float)TEXT_PADDING_TOP *density);//从扫描匡下开始画

layout.draw(canvas);

?canvas.restore()

;//别忘了restore
