集成zxing扫码解决二维码自动放大

只需要在跳转的时候添加intent.putExtra("autoEnlarged", true);即可；
// 扫码
Intent intent = new Intent();
if ("vivo".equals(android.os.Build.MANUFACTURER)) {
    intent.setClass(getContext(), CaptureActivity24.class);
} else {
    intent.setClass(getContext(), android.os.Build.VERSION.SDK_INT > 23 ? CaptureActivity24.class : CaptureActivity.class);
}
intent.putExtra("autoEnlarged", true);
startActivityForResult(intent, 0);
