引言：在不引入PictureSelector module的情况下、进行修改。讲人话 就是PictureSelect采用的是implementation xxx.xxxx.xxx 引入方式、在此基础之上进行扩展修改、且不影响其他功能。

注意：PictureSelector 版本<3.0

先看图（符合预期了再往下看）：

实现步骤：

一、继承修改OverlayView、重写其onDraw方法（目的就是drawText）；

二、复制ucrop_view.xml文件到自己工程的layout中、在ucrop_view.xml中将OverlayView 替换成自己的（ucrop_view.xml 可以在pictureselect库中找到）；

原理（不想看可以跳过 手动狗头）：

找到裁剪框的Rect、在其顶部和底部drawText、就O了、其中矩形关键字mCropViewRect（RectF）；

分析、找到onDraw() 、进入drawDimmedLayer()函数、其中drawDimmedLayer()就是用来画矩形的（就是那个可以拖动的框框）、找到mCropViewRect、在后面DrawText就行了！

具体参考OverlayViewWithText 源码。

以下是已经写好的 直接用吧！

如何使用？：

     //设置裁剪框上下的文字OverlayViewWithText.setPictureUCropText("顶部巴拉巴拉", "底部巴拉巴拉")//设置裁剪框文字距离裁剪框的间距（包含上下文字）OverlayViewWithText.setPictureUCropMargin(10.dp2Px().toFloat())//设置裁剪框文字大小OverlayViewWithText.setPictureUCropTextSize(15f.sp2Px(), 18f.sp2Px())
