android canvas drawText \r\n 换行

用android的canvas drawText的时候,即使text包行\r\n,画出来的仍然不会换行。

这时需要用到TextPaint


						TextPaint textPaint = new TextPaint();
						textPaint.setARGB(0xFF, 0, 0, 0);
						textPaint.setTextSize(20.0F);
						textPaint.setAntiAlias(true);
						StaticLayout layout = new StaticLayout("abc\r\n123", textPaint, 300,
								Alignment.ALIGN_NORMAL, 1.0F, 0.0F, true);
						cv.save();
						cv.translate(20, 20);//从20,20开始画
						layout.draw(cv);
						cv.restore();//别忘了restore
