在com.zxing.camera包中找到CameraManager.java
//修改这里最小最大值，限制扫描框大小
private static final int MIN_FRAME_WIDTH = 240;//240private static final int MIN_FRAME_HEIGHT = 240;//240private static final int MAX_FRAME_WIDTH = 480;//480private static final int MAX_FRAME_HEIGHT = 480;//360CameraManager类的getFramingRect方法
public Rect getFramingRect() { Point screenResolution = configManager.getScreenResolution(); if (screenResolution == null) return null; if (framingRect == null) { if (camera == null) { return null; } //这样设置比微信扫描框稍微大点看着差不多 int width = screenResolution.x * 2 / 3; int height = screenResolution.y * 2 / 4; if (height >= width) { //竖屏 height = width; } else { //黑屏 width = height; } int leftOffset = (screenResolution.x - width) / 2; int topOffset = (screenResolution.y - height) / 3; framingRect = new Rect(leftOffset, topOffset, leftOffset + width, topOffset + height); } return framingRect; }android Zxing实现扫描二维码条形码功能仿微信集成闪光灯生成二维码
