【中文标题】如何将 ZXing 库集成到 Android Studio 进行条码扫描?【英文标题】:How to integrate ZXing Library to Android Studio for Barcode Scanning? 【发布时间】:2015-03-07 05:45:19 【问题描述】:我一直在互联网上寻找如何将 zxing 库包含到我的项目中,我找到了这个教程:http://blog.dihaw.com/integrating-zxing-in-your-android-app-as-standalone-scanner/
但是当我到达您需要检查 BeepManager 以添加 R 导入的地步时,我的项目中(即使在 MainActivity 上)出现了找不到 R 的各种错误。
我还发现了这个https://github.com/journeyapps/zxing-android-embedded/blob/master/README.md,它似乎更容易,因为它是由 gradle 自动集成的,但是当我同步它时会弹出一个错误,它找不到文件。
任何帮助将不胜感激 :) 我是 Android Studio 的新手。
编辑:
我将第二种方法的设置(带有 gradle 设置的那个)添加到我的 build.gradle 并弹出 4 个错误:
Error:Failed to find: com.embarkmobile:zxing-android-legacy:2.0.0
Error:Failed to find: com.google.zxing:core:3.0.1
Error:Failed to find: com.embarkmobile:zxing-android-integration:2.0.0
Error:Failed to find: com.embarkmobile:zxing-android-minimal:2.0.0
有什么帮助吗?
---答案---
为了解决这个问题,我需要在 Gradle 上禁用 Offline Work。
Android Studio 的设置>Gradle>取消选中“离线工作”【问题讨论】:
具体的错误信息会很有帮助。您可以使用块引用类型的降价格式(行首的>
)将其分开并确保您的问题可读。使用问题底部的edit link 进行更改。
ZXing 不是读取条码的唯一方法。从 2016 年开始,使用Android Barcode API 变得更加容易。
@DanDascalescu 您指向 Android Barcode API 的链接已被 SE 删除。还有其他建议吗?
【参考方案1】:
您需要将以下内容添加到您的 build.gradle
文件中:
repositories
mavenCentral()
maven
url "http://dl.bintray.com/journeyapps/maven"
dependencies
// Supports Android 4.0.3 and later (API level 15)
compile 'com.journeyapps:zxing-android-embedded:2.0.1@aar'
// Supports Android 2.1 and later (API level 7), but not optimal for later Android versions.
// If you only plan on supporting Android 4.0.3 and up, you don't need to include this.
compile 'com.journeyapps:zxing-android-legacy:2.0.1@aar'
// Convenience library to launch the scanning and encoding Activities.
// It automatically picks the best scanning library from the above two, depending on the
// Android version and what is available.
compile 'com.journeyapps:zxing-android-integration:2.0.1@aar'
// Version 3.0.x of zxing core contains some code that is not compatible on Android 2.2 and earlier.
// This mostly affects encoding, but you should test if you plan to support these versions.
// Older versions e.g. 2.2 may also work if you need support for older Android versions.
compile 'com.google.zxing:core:3.0.1'
我的build.gradle
文件是这样的:
apply plugin: 'com.android.application'
android
compileSdkVersion 21
buildToolsVersion "21.1.2"
defaultConfig
applicationId "com.myapplication2"
minSdkVersion 16
targetSdkVersion 21
versionCode 1
versionName "1.0"
buildTypes
release
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
repositories
mavenCentral()
maven
url "https://raw.github.com/embarkmobile/zxing-android-minimal/mvn-repo/maven-repository/"
dependencies
compile fileTree(dir: 'libs', include: ['*.jar'])
compile 'com.android.support:appcompat-v7:21.0.3'
// Supports Android 4.0.3 and later (API level 15)
compile 'com.embarkmobile:zxing-android-minimal:2.0.0@aar'
// Supports Android 2.1 and later (API level 7), but not optimal for later Android versions.
// If you only plan on supporting Android 4.0.3 and up, you don't need to include this.
compile 'com.embarkmobile:zxing-android-legacy:2.0.0@aar'
// Convenience library to launch the scanning and encoding Activities.
// It automatically picks the best scanning library from the above two, depending on the
// Android version and what is available.
compile 'com.embarkmobile:zxing-android-integration:2.0.0@aar'
// Version 3.0.x of zxing core contains some code that is not compatible on Android 2.2 and earlier.
// This mostly affects encoding, but you should test if you plan to support these versions.
// Older versions e.g. 2.2 may also work if you need support for older Android versions.
compile 'com.google.zxing:core:3.0.1'

另外,关于如何使用,请参考我在 *** 上的回答here
它包含我测试过的方法和简单代码。

我将这些设置添加到我的 build.gradle 并弹出 4 个错误:错误:找不到:com.embarkmobile:zxing-android-legacy:2.0.0 错误:找不到:com. google.zxing:core:3.0.1 错误:找不到:com.embarkmobile:zxing-android-integration:2.0.0 错误:找不到:com.embarkmobile:zxing-android-minimal:2.0.0 有什么帮助吗?这与之前发生的错误相同 解决了!我会详细说明一个答案 尝试使用这个库。轻松集成 Xzing。 github.com/journeyapps/zxing-android-embedded @Mauriciosilva 你是怎么解决的 Error:Failed to find: com.embarkmobile:zxing-android-legacy:2.0.0 error? @prgmrDev 我在 AS 设置中启用了 OfflineWork。阅读我编辑的问题部分,我写了如何禁用它:)【参考方案2】:从 zxing-android-embedded 版本 3 开始,您只需将这些添加到您的 build.gradle
文件中:
repositories
jcenter()
dependencies
compile 'com.journeyapps:zxing-android-embedded:3.0.2@aar'
compile 'com.google.zxing:core:3.2.0'
按照以下步骤操作:https://github.com/journeyapps/zxing-android-embedded/
它现在还支持纵向模式,只需对 IntentIntegrator
进行简单更改,以及更简单的自定义视图方法。
【讨论】:
嗨,兄弟。你在 ZXing Embedded 中使用过 CompoundBarcodeView 吗? 是的。我从 ViewFinder 的可见性作为 INVISIBLE 开始,并在单击按钮时更改为 VISIBLE,这也调用 decodeSingle 进行单次扫描。这样,视图会显示相机看到的内容,但没有取景器的红线和黄色斑块,直到用户真正想要捕捉为止。但是,当然,这正是我的应用所需要的,您的可能需要它始终可见并捕获。 这应该是被接受的答案,我正在为 Eclipse 使用同一个项目。在这里阅读我的答案***.com/questions/4782543/…【参考方案3】:集成 ZXing 以进行条码或二维码扫描的最简单方法。
完整参考:Scan Barcode ZXing Android
添加依赖
compile 'me.dm7.barcodescanner:zxing:1.9'
扫描活动
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.util.Log;
import com.google.zxing.Result;
import me.dm7.barcodescanner.zxing.ZXingScannerView;
public class ScanActivity extends AppCompatActivity implements ZXingScannerView.ResultHandler
private ZXingScannerView mScannerView;
@Override
public void onCreate(Bundle state)
super.onCreate(state);
mScannerView = new ZXingScannerView(this); // Programmatically initialize the scanner view
setContentView(mScannerView); // Set the scanner view as the content view
@Override
public void onResume()
super.onResume();
mScannerView.setResultHandler(this); // Register ourselves as a handler for scan results.
mScannerView.startCamera(); // Start camera on resume
@Override
public void onPause()
super.onPause();
mScannerView.stopCamera(); // Stop camera on pause
@Override
public void handleResult(Result rawResult)
// Do something with the result here
// Log.v("tag", rawResult.getText()); // Prints scan results
// Log.v("tag", rawResult.getBarcodeFormat().toString()); // Prints the scan format (qrcode, pdf417 etc.)
MainActivity.tvresult.setText(rawResult.getText());
onBackPressed();
// If you would like to resume scanning, call this method below:
//mScannerView.resumeCameraPreview(this);
【讨论】:
【参考方案4】:我可以用这个:
repositories mavenCentral()
maven url "https://raw.github.com/embarkmobile/zxing-android-minimal/mvn-repo/maven-repository/"
compile 'com.google.zxing:core:3.2.1'
compile 'com.embarkmobile:zxing-android-minimal:2.0.0@aar'
compile 'com.embarkmobile:zxing-android-integration:2.0.0@aar'
我推荐使用 IntentIntegrator
IntentIntegrator integrator = new IntentIntegrator(getActivity());
integrator.forSupportFragment(this).initiateScan();
requestCode 与 IntentIntegrator.REQUEST_CODE 一起返回
