是的,过时还能用,能21开始整个 Camera类都被已经过时,google建议用Camera2,大佬你可以自己修改成Camera2的Api

大佬，按返回键就退出，程序崩了。怎么回事呢？ Caused by: java.lang.NullPointerException: Attempt to invoke virtual method 'android.os.Bundle android.content.Intent.getExtras()' on a null object reference

zybieku commented 6 years ago

@liaomabao 你用的是新版么,这个空指针的原因是返回的时候,二维码数据为空,再mainActivity里面的回调里面做一下空指针判断就行啦.

zybieku commented 6 years ago

@liaomabao 我刚才改了,你重新下载运行下demo,看还有问题麽

liaomabao commented 6 years ago

是的，这样就行了：if (requestCode == QR_CODE && data != null) {

zybieku commented 6 years ago

@liaomabao 嗯啦.大佬您还有问题麽!

liaomabao commented 6 years ago

@zybieku 挺好的，简单易用，谢谢大兄弟，这块没有问题了。but，最好是把二维码生成也一起封装了呗，这两玩意儿是一对，嘿嘿。

你好，怎么才能扫完一次之后再重复扫码？

zybieku commented 6 years ago

@chenfeizi 可以呀 ,1:你打开重新扫码,二是:修改源码,让他扫码成功后也不关闭,如下图

chenfeizi commented 6 years ago

[ 还是只能扫码一次，我在这

checkResult(final String result) 方法里面

得到扫码结果之后就不能再次扫码了，必须得关闭这页面重新进来才能在扫一次，有没有什么方法可以立即重新扫码？]

zybieku commented 6 years ago

可以呀，不过要改handler 解码部分的源码了，因为现在做的是解码成功就handler关闭消息发送

chenfeizi commented 6 years ago

不会改呀，楼主什么时候有时间能不能优化下，非常感谢！

chenfeizi commented 6 years ago

大哥，急救，用你的扫码怎么打开闪光灯？

zybieku commented 6 years ago

@chenfeizi 周末才有时间弄啊，这周末好么

大神，运行报错so库找不到。在网上找到相关的so库替换，直接报错。能否提供较全的so库？
