将 ZXing 库直接集成到我的 Android 应用程序中

下面是一个关于如何使用 ZXing 库生成和显示二维码而不必安装第三方应用程序的分步指南。注:你不必用 ANT 或任何其他构建工具来构建 ZXing。文件 core.jar在已发布的压缩文件中可用(请参阅下文)。

1. 下载 最新发布的 ZXing——(ZXing-*.zip)
2. 解压缩这个压缩文件并在 core/目录下找到 core.jar。
3. 如果您正在使用 EclipseIDE，请将 core.jar拖放到 Android 项目的 libs目录中。当被问及时，选择 收到。
4. 将下面给出的两个类(Contents.java和 QRCodeEncoder.java)复制到 Android 项目的主包中。
5. 在你的活动中创建一个 ImageView项目来显示生成的二维码(如果你还没有的话)。下面是一个例子:
6. 使用下面的代码片段生成位图格式的 QR 代码并以 ImageView显示。

下面是要添加到活动布局 XML 文件中的 ImageView元素:

<ImageView
android:id="@+id/qrCode"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginTop="50dp"
android:layout_centerHorizontal="true"/>

代码片段:

// ImageView to display the QR code in.  This should be defined in
// your Activity's XML layout file
ImageView imageView = (ImageView) findViewById(R.id.qrCode);


String qrData = "Data I want to encode in QR code";
int qrCodeDimention = 500;


QRCodeEncoder qrCodeEncoder = new QRCodeEncoder(qrData, null,
Contents.Type.TEXT, BarcodeFormat.QR_CODE.toString(), qrCodeDimention);


try {
Bitmap bitmap = qrCodeEncoder.encodeAsBitmap();
imageView.setImageBitmap(bitmap);
} catch (WriterException e) {
e.printStackTrace();
}

这里是 Contents.java

如果只需要 zxing 的 core.jar，可以跳过这个过程，从 开始维基页面获得预构建的 JAR

最新的 ZXing (2.2)在 core 文件夹下没有 core.jar，但是您可以从 ZXing 这里是 Maven 仓库获得 core.jar

放下

compile 'com.google.zxing:core:2.3.0'

在使用 Android Studio 和 Gradle 构建系统之前，你可以把它们放到你的 Gradle 依赖项中。

由于有些答案已经过时，我想提供我自己的-

要像 他们的维基百科建议的那样将 ZXing 库集成到 Android 应用程序中，你需要在你的项目中添加2个 Java 文件:

• 意图集成器.java
• 意向结果 java

然后在 安卓工作室中向 建造，分级文件添加以下代码行:

dependencies {
....
compile 'com.google.zxing:core:3.2.1'
}

或者如果仍然使用 带 ADT 插件的 Eclipse，将 Core.jar文件添加到项目的 Libs子目录(这里是 全屏幕视窗和 全屏 Mac) :

最后，将这段代码添加到 MainActivity.java:

public void scanQRCode(View v) {
IntentIntegrator integrator = new IntentIntegrator(MainActivity.this);
integrator.initiateScan(IntentIntegrator.QR_CODE_TYPES);
}


@Override
public void onActivityResult(int requestCode, int resultCode, Intent intent) {
IntentResult result =
IntentIntegrator.parseActivityResult(requestCode, resultCode, intent);
if (result != null) {
String contents = result.getContents();
if (contents != null) {
showDialog(R.string.result_succeeded, result.toString());
} else {
showDialog(R.string.result_failed,
getString(R.string.result_failed_why));
}
}
}


private void showDialog(int title, CharSequence message) {
AlertDialog.Builder builder = new AlertDialog.Builder(this);
builder.setTitle(title);
builder.setMessage(message);
builder.setPositiveButton(R.string.ok_button, null);
builder.show();
}

生成的应用程序将要求安装并启动 条形码扫描器应用程序(它将在扫描后自动返回到您的应用程序) :

此外，如果你想构建和运行 ZXing Test 应用程序作为你自己的应用程序的灵感:

然后你需要4个来自 GitHub的 Java 文件:

• BenchmarkActivity.java
• BenchmarkAsyncTask.java
• BenchmarkItem.java
• Java

和3个来自 Maven 仓库的罐子文件:

• Core.jar
• Android-core. jar
• Android 集成. jar

(您可以自己用 mvn package构建 Jar 文件-如果您从 GitHub 签出 ZXing 并在您的计算机上安装 蚂蚁和 Maven工具)。

注意: 如果您的项目不能识别 Jar 文件，您可能需要在 Project Properties 中提高 Java 版本:

那个

compile 'com.google.zxing:core:2.3.0'

不幸的是，这招对我不管用。

这就是对我有效的方法:

dependencies {
compile 'com.journeyapps:zxing-android-embedded:3.0.1@aar'
compile 'com.google.zxing:core:3.2.0'
}

你可在此找到连结: Https://github.com/journeyapps/zxing-android-embedded

在 Eclipse 中一步一步地设置 zxing 3.2.1

1. 从“ https://github.com/zxing/zxing”下载 zxing-master. zip
2. 解压缩 zxing-master. zip，使用 eclipse 在 zxing-master 中导入“ android”项目
3. 从“ http://repo1.maven.org/maven2/com/google/zxing/core/3.2.1/”下载 core-3.2.1.jar
4. 在“ android”项目中创建“ libs”文件夹，并将 cor-3.2.1.jar 粘贴到 libs 文件夹中
5. 点击 project: 选择“ properties”-> “ Java Compiler”将级别更改为1.7。然后点击“ Android”，将“ Project build target”更改为 Android 4.4.2 + ，因为使用1.7需要使用 Android 4.4进行编译
6. 如果“ zxing-master/android/app/src/main/java/com/google/zxing/client/android/Camera/”中不存在“ CameraConfigurationUtils.java”，你可以从“ zxing-master/android-core/src/main/java/com/google/zxing/client/android/Camera/”中复制它并粘贴到你的项目中。
7. 清洁和建设项目。如果您的项目显示关于“ switch-case”的错误，您应该将它们更改为“ If-else”。
8. 完成。清洁和建设项目。
9. 参考链接: 使用 ZXing 创建一个 Android 条形码扫描应用程序

我尝试了所有可能的方法来实现这一点，然后我发现了 JourneyApps 的 xZing 缩小版。我已经把它移植到 Eclipse 上并在 GitHub 上分享了。

如果您正在使用 Eclipse，请使用此项目:-

Https://github.com/hiteshsahu/xzing-barcode-scanner-minified-eclipse

如果您正在使用 Studio，请使用此项目:-

Https://github.com/journeyapps/zxing-android-embedded

优势

1. 应用程序中的内置条形码扫描器不需要使用 playstore 安装第三方应用程序。

2. 你不需要在核心，安卓客户端等罐子之间混淆，只需放下这个包和相关的布局在您的项目，你是好去。只有 Jar 需要的是 Zxing: core: 3.2.0 com.google.zxing: core: 3.2.0，您可以从中下载

   Http://mvnrepository.com/artifact/com.google.zxing/core/3.2.0

3. 不需要添加成吨的软件包 参见下面的图片进行比较

以前:-

之后:-

4. 最重要的是他们是 高度可定制即。您可以添加闪光灯，使用它的片段和支持方向的变化。

5. 可以在 Cordova 应用中使用此捕获活动进行条形码扫描。

应用程序清单中的捕获活动如下所示

  <activity
android:name="com.journeyapps.barcodescanner.CaptureActivity"
android:clearTaskOnLaunch="true"
android:configChanges="orientation|keyboardHidden"
android:exported="false"
android:screenOrientation="fullSensor"
android:theme="@android:style/Theme.NoTitleBar.Fullscreen"
android:windowSoftInputMode="stateAlwaysHidden" >
<intent-filter>
<action android:name="com.google.zxing.client.android.SCAN" />


<category android:name="android.intent.category.DEFAULT" />
</intent-filter>
</activity>

和插件将看起来像这样

public class BarcodeScanner extends CordovaPlugin {
public static final int REQUEST_CODE = 0x0ba7c0de;


private static final String SCAN = "scan";
private static final String CANCELLED = "cancelled";
private static final String FORMAT = "format";
private static final String TEXT = "text";

/**

public void scan(JSONArray args) {

}


// avoid calling other phonegap apps

}

*/
@Override
public void onActivityResult(int requestCode, int resultCode, Intent intent) {
if (requestCode == REQUEST_CODE) {
if (resultCode == Activity.RESULT_OK) {
JSONObject obj = new JSONObject();
try {
obj.put(TEXT, intent.getStringExtra("SCAN_RESULT"));

}

融合快乐! ！

为什么使用外部库，当谷歌播放服务(自从版本 7.8.0)包括一个条形码解码器。

简单多了。

只需在应用程序级别的分级文件中包含依赖关系即可

compile 'com.journeyapps:zxing-android-embedded:3.0.1@aar'
compile 'com.google.zxing:core:3.2.0'

在 xml 文件中定义一个按钮，并在 OnCreate ()和按钮的 OnClick 监听器内部的 Java 文件中编写以下代码

new IntentIntegrator(this).initiateScan();

并在 Java 文件的 OnCreate ()之后编写以下代码

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
IntentResult result = IntentIntegrator.parseActivityResult(requestCode, resultCode, data);
if(result != null) {
if(result.getContents() == null) {
Log.d("MainActivity", "Cancelled scan");
Toast.makeText(this, "Cancelled", Toast.LENGTH_LONG).show();
} else {
Log.d("MainActivity", "Scanned");
String st_scanned_result = result.getContents();
Toast.makeText(this, "Scanned: " + result.getContents(), Toast.LENGTH_LONG).show();


}
}


}

我最近在 ios 和 android 中都使用了谷歌移动视觉。我强烈推荐使用谷歌条形码扫描。它对任何方向都非常敏感，处理时间也非常快。它被称为谷歌移动视觉。

条形码扫描器 API 在任何情况下实时检测条形码 你也可以检测和解析一些条形码 不同的格式在同一时间。

Https://developers.google.com/vision/

Https://codelabs.developers.google.com/codelabs/bar-codes/#0

我只是写了一个方法，解码生成的条形码，Bitmap到 String。

它完全符合要求，只是没有 CaptureActivity..。

因此，可以跳过 build.gradle中的 android-integration库:

dependencies {
// https://mvnrepository.com/artifact/com.google.zxing
compile('com.google.zxing:core:3.3.0')
compile('com.google.zxing:android-core:3.3.0')
}

该方法如下(在 jUnit 测试中实际解码生成的条形码) :

import android.graphics.Bitmap;


import com.google.zxing.BinaryBitmap;
import com.google.zxing.LuminanceSource;
import com.google.zxing.MultiFormatReader;
import com.google.zxing.NotFoundException;
import com.google.zxing.RGBLuminanceSource;
import com.google.zxing.common.HybridBinarizer;
import com.google.zxing.Result;


protected String decode(Bitmap bitmap) {


MultiFormatReader reader = new MultiFormatReader();
String barcode = null;


int[] intArray = new int[bitmap.getWidth() * bitmap.getHeight()];
bitmap.getPixels(intArray, 0, bitmap.getWidth(), 0, 0, bitmap.getWidth(), bitmap.getHeight());
LuminanceSource source = new RGBLuminanceSource(bitmap.getWidth(), bitmap.getHeight(), intArray);
BinaryBitmap binary = new BinaryBitmap(new HybridBinarizer(source));


try {


Result result = reader.decode(binary);
// BarcodeFormat format = result.getBarcodeFormat();
// ResultPoint[] points = result.getResultPoints();
// byte[] bytes = result.getRawBytes();
barcode = result.getText();


} catch (NotFoundException e) {
e.printStackTrace();
}
return barcode;
}

这个库工作起来很有魅力，易于集成和使用

2020年更新: 只要把这个添加到你的格拉德尔文件。它完美地工作！
