重要的第二步

2 I在 CameraManager 类, 方法getFramingRect 替换

intwidth=MIN_FRAME_WIDTH;intheight=MIN_FRAME_HEIGHT;if(context.getResources().getConfiguration().orientation==Configuration.ORIENTATION_PORTRAIT){inttmp=7*screenResolution.x/8;width=(tmp)<MIN_FRAME_WIDTH?MIN_FRAME_WIDTH:(tmp);tmp=1*screenResolution.y/3;height=(tmp)<MIN_FRAME_WIDTH?MIN_FRAME_WIDTH:((tmp)>MAX_FRAME_HEIGHT?MAX_FRAME_HEIGHT:(tmp));}else{//原始代码width=findDesiredDimensionInRange(screenResolution.x,MIN_FRAME_WIDTH,>MAX_FRAME_WIDTH);height=findDesiredDimensionInRange(screenResolution.y,MIN_FRAME_HEIGHT,MAX_FRAME_HEIGHT);}

正确显示扫描框。

老版本没有

findDesiredDimensionInRange

这个方法

加上

private static int findDesiredDimensionInRange(int resolution, int hardMin, int hardMax) {

int dim = 5 * resolution / 8; // Target 5/8 of each dimension

if (dim < hardMin) {

return hardMin;

}

if (dim > hardMax) {

return hardMax;

}

return dim;

}
