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;
}
