QR code扫描仪 [英] QR code scanner

问题描述

我想在我的应用程序创建一个QR code扫描仪。

I would like to create a QR code scanner in my app.

我通过zxing去了，但我无法理解。我感兴趣的QR codeS而已。

I went through the zxing ,but I could not understand it. I am interested in QR codes only.

所有帮助是非常AP preciated。

All help is highly appreciated.

推荐答案

将com.google.zxing.client的副本。*源码包到项目中。您可以启动zxing扫描活动是这样的：

Place a copy of the com.google.zxing.client.* source packages into your project. You can start the zxing scanning activity like this:

Intent intent = new Intent(this, CaptureActivity.class);
startActivityForResult(intent, 0);

在你调用CaptureActivity中您可以处理结果时，扫描具有以下onActivityResult方法完成同样的活动：

In the same activity that you invoked the CaptureActivity in you can handle the result when the scan completes with the following onActivityResult method:

protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        if (data != null) {
            String response = data.getAction();

            if(Pattern.matches("[0-9]{1,13}", response)) {
                // response is a UPC code, fetch product meta data
                // using Google Products API, Best Buy Remix, etc.          
            } else {
                // QR codes - phone #, url, location, email, etc. 
                Intent intent = new Intent(Intent.ACTION_VIEW);
                intent.setData(Uri.parse(response));
                startActivity(intent);
            }
        }
    }   

希望这有助于。
