在Android的Studio集成的ZXing [英] Integrate ZXing in Android Studio
问题描述
我会开始解释一切我都做，到底是什么问题的步骤。
I'll start explaining all the steps I have done and in the end what is the problem.
- 下载ZXing-2.2 <一href="https://$c$c.google.com/p/zxing/downloads/list">https://$c$c.google.com/p/zxing/downloads/list
- 为Extrac所有zxing-2.2。
- 在下载和安装Apache Ant的<一个href="http://www.youtube.com/watch?v=XJmndRfb1TU">http://www.youtube.com/watch?v=XJmndRfb1TU
- 通过使用命令行的Windows（运行 - > CMD）的定位到解压目录
- 在命令行窗口 - 输入'蚂蚁-f核心/ build.xml文件'preSS输入，让Apache的工作，它的魔力
- Download ZXing-2.2 https://code.google.com/p/zxing/downloads/list
- Extrac all in zxing-2.2.
- Download and install Apache Ant http://www.youtube.com/watch?v=XJmndRfb1TU
- With the use of Windows Commandline (Run->CMD) navigate to the extracted directory
- In the commandline window - Type 'ant -f core/build.xml' press enter and let Apache work it's magic
在这一刻像<一个href="http://stackoverflow.com/questions/4782543/integration-zxing-library-directly-into-my-android-application">Integration直接ZXing库到我的Android应用程序
但Wooops，构建文件：核心\ build.xml文件不存在生成失败OK。 6. 导入ZXing - 缺少核心/ build.xml文件
But Wooops, "Buildfile: core\build.xml does not exists! Build failed. ok. 6. Importing ZXing - missing core/build.xml
现在是的，我有我的core.jar添加。
Now yes, i have my core.jar.

所有的错误都是错误：需要不断前pression和 我看<一href="http://stackoverflow.com/questions/11226941/error-in-switch-cases-of-zxing-project-in-android">Error在ZXing项目的切换例机器人 我改变所有交换机上的，如果别人的。

现在我可以在资源管理器中看到/安卓/ / zging_demoProject /和外部的库
Now I can see in the explorer /android/ /zging_demoProject/ and External Libraries
现在我改变我的code涂扫描QR
Now i change my code tu scan QR
AndroidManifest.xml中
AndroidManifest.xml

和崩溃。
logcat的

我可以在AndroidManifest.xml中看到这一行
I can see in AndroidManifest.xml in this line
android:name="com.google.zxing.client.android.CaptureActivity"
CaptureActivity红色和错误说：无法解析符号CaptureActivity
"CaptureActivity" in red and the error say: Cannot resolve symbol 'CaptureActivity'

现在CaptureActivity看起来不错
Now CaptureActivity looks good

我觉得我去使用的应用程序和意图，但现在我想做好这项工作，如果有人现在什么发生请告诉我：D谢谢
I think i go use the application and intents, but now i want do this work, if someone now whats happen tell me please :D Thanks!
推荐答案
好男人，因为我今天的任务是整合ZXING到一个Android应用程序，并有输入没有很好的来源都结束了，我会给你一个提示什么让我获得成功 - ，因为它原来是很容易
Okay guys, as my task today was to integrate ZXING into an Android application and there were no good sources for input all over, I will give you a hint what made me be successful - because it turned out to be very easy.
有一个真正的方便的git仓库，提供了zxing的Android库项目为AAR存档。
There is a real handy git repository that provides the zxing android library project as an AAR archive.
所有你需要做的就是它添加到您的build.gradle
All you have to do is add this to your build.gradle
repositories {
jcenter()
}
dependencies {
compile 'com.journeyapps:zxing-android-embedded:3.0.2@aar'
compile 'com.google.zxing:core:3.2.0'
}
和摇篮做所有的魔法编译code，使得它在你的应用程序进行访问。
and Gradle does all the magic to compile the code and makes it accessible in your app.
要算账启动扫描仪，使用这个类/方法： 从活动：
To start the Scanner afterwards, use this class/method: From the Activity:
new IntentIntegrator(this).initiateScan(); // `this` is the current Activity
这是一个片段：
IntentIntegrator.forFragment(this).initiateScan(); // `this` is the current Fragment
// If you're using the support library, use IntentIntegrator.forSupportFragment(this) instead.
有几个自定义选项：
IntentIntegrator integrator = new IntentIntegrator(this);
integrator.setDesiredBarcodeFormats(IntentIntegrator.ONE_D_CODE_TYPES);
integrator.setPrompt("Scan a barcode");
integrator.setCameraId(0); // Use a specific camera of the device
integrator.setBeepEnabled(false);
integrator.setBarcodeImageEnabled(true);
integrator.initiateScan();
他们有一个 样本项目 ，并提供多种集成的例子：
They have a sample-project and are providing several integration examples:
- <一个href="https://github.com/journeyapps/zxing-android-embedded/blob/master/sample/src/main/java/example/zxing/AnyOrientationCaptureActivity.java"相对=nofollow> AnyOrientationCaptureActivity
- <一个href="https://github.com/journeyapps/zxing-android-embedded/blob/master/sample/src/main/java/example/zxing/ContinuousCaptureActivity.java"相对=nofollow> ContinuousCaptureActivity
- <一个href="https://github.com/journeyapps/zxing-android-embedded/blob/master/sample/src/main/java/example/zxing/CustomScannerActivity.java"相对=nofollow> CustomScannerActivity
- <一个href="https://github.com/journeyapps/zxing-android-embedded/blob/master/sample/src/main/java/example/zxing/ToolbarCaptureActivity.java"相对=nofollow> ToolbarCaptureActivity
- AnyOrientationCaptureActivity
- ContinuousCaptureActivity
- CustomScannerActivity
- ToolbarCaptureActivity
如果你已经访问过你会看到，我只是复制和链接，粘贴从混帐自述的code。如果没有，去那里得到一些更深入的了解和code例子！
If you already visited the link you gonna see that i just copy&pasted the code from the git README. If not, go there to get some more insight and code examples!
希望对未来的读者有所帮助。和平：）
Hope to be helpful for future readers. Peace :)
