适配屏幕分辨率

直接上代码：参考注释

 public static Rect calRealSceenRect(Rect rectFace, int width, int height, int rotation ,Boolean isBackCamera) {         int oriention;         oriention = rotation / 90;         Rect rect = new Rect(rectFace);         for (int i = 0; i < oriention; i++) {             for (int j = 0; j < 4; j++) {                 int tempt = rect.top;                 rect.top = rect.right;                 rect.right = rect.bottom;                 rect.bottom = rect.left;                 rect.left = tempt;             }         }           //0 横屏 对应竖屏         int tempt = rect.top;         rect.top = rect.left;         rect.left = rect.bottom;         rect.bottom = rect.right;         rect.right = tempt;          //前置 需要镜像         if (!isBackCamera){             int tempMirror=rect.top;             rect.top=rect.bottom;             rect.bottom=tempMirror;         }          //计算实际宽高的高度差  就转化完成android的标准坐标系。         rect.left = height - rect.left;         rect.right = height - rect.right;          if (!isBackCamera) {             rect.top = width - rect.top;             rect.bottom = width - rect.bottom;         }            return rect;     }
