使用相机读取二维码 - Android

问题描述

我目前正在研究在 Android 中构建一个闹钟应用程序.我对使用 QR 码进行编程完全陌生.我对此一无所知.但现在，我想找出创建具有二维码功能的应用程序的可行性.(我有两周的时间来构建它)

I am currently researching to build an alarm clock application in Android. I am utterly and completely new to programming with QR codes. I know nothing about it. But right now, I want to find out the feasibility of creating an application with QR code functionality. (I have two weeks to build this)

我的第一个问题是:我是否必须在代码中自己处理相机，即我是否必须启动它然后关闭它然后处理 QR 图像?

My first question is: would I have to handle the camera myself in the code i.e. do I have to fire it up and then close it and then process the QR image?

第二问:我如何创建二维码，然后当我扫描它时，它怎么知道它扫描的是正确的?我想打印一个，放在厨房或浴室，然后当闹钟响起时，我必须在闹钟关闭之前扫描代码.

2nd Q: How would I create the QR code and then when I scan it, how does it know it scanned the right one? I want to print one, place it in the kitchen or bathroom and then when the alarm goes off, I have to scan the code before the alarm turns off.
