刚刚想耍耍二维码,想到了zxing和zbar,又想到zxing是Google老爹的,想想就算了吧,虽然zbar快但是识别错误率也高不少.随手Google了下*zxing 集成*好像都是说什么拷贝项目到自己的工程中,我不信Gradle集成这么方便了为何不用.于是我来到zxing的 Github 主页 https://github.com/zxing/zxing,在README的引导下来到Get Start页面,里面有如下说明:

Maven

core/, javase/, android-integration and zxingorg can be used directly in a Maven-based project without any download or installation. Instead, add as dependencies from groupID com.google.zxing artifactIDs core, javase, android-integration or zxingorg:

<dependencies>
  ...
  <dependency> <groupId>com.google.zxing</groupId> <artifactId>core</artifactId> <version>(the current version)</version> </dependency> </dependencies> 

虽然没说明 Gradle 如何集成,但是发布过lib到jcenter的应该知道,maven和Gradle的关系.

上面maven仓库信息对应的Gradle为:

compile 'com.google.zxing:core:3.3.0'

compile '<groupId>:<artifactId>:<version>' 

记起来也很简单,就是把上面三个参数用:连接即可.

其中 version对应版本有很多,建议使用最新的,我现在看到最新的Release版本为3.3.0.

所以在 Android studio 的工程 Module的build.gradle下添加一行依赖即可:

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2', { exclude group: 'com.android.support', module: 'support-annotations' }) compile 'com.android.support:appcompat-v7:25.3.1' compile 'com.android.support:support-v4:25.3.1' compile 'com.android.support:design:25.3.1' compile 'com.android.support.constraint:constraint-layout:1.0.2' testCompile 'junit:junit:4.12' //添加 zxing compile 'com.google.zxing:core:3.3.0' }

其他的项目集成以此类推.
