如何使用Zxing在安卓 [英] How to use Zxing in android

问题描述

我是新来Zxing。我做用zxing在我的Andr​​oid应用程序吧code转换。任何人都可以指导我如何包括zxing到Android设备。

I am new to Zxing. I am doing barcode conversion using zxing in my android application. Can anyone guide me how to include zxing to android device.

推荐答案

如果该zxing吧code扫描仪安装在移动，它很容易的：

If the zxing barcode scanner is installed in the mobile, its very easy:

Intent intent = new Intent("com.google.zxing.client.android.SCAN");
       intent.putExtra("SCAN_MODE", "PRODUCT_MODE");//for Qr code, its "QR_CODE_MODE" instead of "PRODUCT_MODE"
       intent.putExtra("SAVE_HISTORY", false);//this stops saving ur barcode in barcode scanner app's history
       startActivityForResult(intent, 0);

和 OnActivityResult ：

    @Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        super.onActivityResult(requestCode, resultCode, data);
        if (requestCode == 0) {
            if (resultCode == RESULT_OK) {
                    String contents = data.getStringExtra("SCAN_RESULT"); //this is the result
            } else 
            if (resultCode == RESULT_CANCELED) {
              // Handle cancel
            }
        }
    }

如果它没有安装：美国可以把这个code。在try-catch块，并捕捉异常，ü可以做到这一点：

If its not installed: u can put this code in try-catch block and catching the exception, u can do this:

Uri marketUri = Uri.parse("market://details?id=com.google.zxing.client.android");
Intent marketIntent = new Intent(Intent.ACTION_VIEW,marketUri);
startActivity(marketIntent);

因此​​重定向应用程序，以安卓市场和乌尔应用程序继续运行一次，如果吧code扫描安装。

So it redirects the app to android market and ur app continues running once if the barcode scanner is installed.

如果妳不想使用在乌拉圭回合应用程序中的其他应用程序，U必须下载zxing库，并尝试使用的类core.jar添加文件（它采用Apache Ant创建）。按照本教程做到这一点： https://github.com/zxing/zxing/wiki/Getting-Started-Developing

If u dont want to use the other app in ur app, U have to download zxing library and try using the classes from core.jar file(it is created using apache ant). Follow this tutorial to do that: https://github.com/zxing/zxing/wiki/Getting-Started-Developing
