//这里可以用intent传递一些参数，比如扫码聚焦框尺寸大小，支持的扫码类型。 // //设置扫码框的宽 // intent.putExtra(Constant.EXTRA_SCANNER_FRAME_WIDTH, 400); // //设置扫码框的高 // intent.putExtra(Constant.EXTRA_SCANNER_FRAME_HEIGHT, 400); // //设置扫码框距顶部的位置 // intent.putExtra(Constant.EXTRA_SCANNER_FRAME_TOP_PADDING, 100); // Bundle bundle = new Bundle(); // //设置支持的扫码类型 // bundle.putSerializable(Constant.EXTRA_SCAN_CODE_TYPE, mHashMap); // intent.putExtras(bundle); startActivityForResult(intent, RESULT_REQUEST_CODE); 这里可以使用intent传递一些配置参数。支持有设置扫码框的大小，及位置；设置支持的扫码类型。目前支持的自定义配置不多，后续有机会再扩充。 跳转的时候要有startActivityForResult来跳转，这样在扫码成功之后，返回的结果可以在onActivityResult方法中处理代码如下： @Override protected void onActivityResult(int requestCode, int resultCode, Intent data) { if (resultCode == RESULT_OK) { switch (requestCode) { case RESULT_REQUEST_CODE: if (data == null) return; String type = data.getStringExtra(Constant.EXTRA_RESULT_CODE_TYPE); String content = data.getStringExtra(Constant.EXTRA_RESULT_CONTENT); Toast.makeText(MainActivity.this,"codeType:" + type + "-----content:" + content,Toast.LENGTH_SHORT).show(); break; default: break; } } super.onActivityResult(requestCode, resultCode, data); } ---------------------------------------- ## **YZxing版本更新说明** ## 目前最新版为v2.2！！ -------------       目前YZxing已经更新到了v2.1 ，更新内容有：     1.修改空指针导致的的闪退bug。     2.添加从相册获取二维码功能（用户可以选择是否使用该功能）。      首先通过在build.gradle文件中添加如下编译语句将YZxing-lib库添加到项目中。 compile 'com.yangy:YZxing-lib:2.1' （或者在直接把本仓库里面的YZxing库下载下来，添加到项目中。）     使用方式与1.1版本一致，注意的是如需使用**从相册获取二维码功能**则需要在intent中添加是否启用scan_from_pic，默认是FALSE：       **//       //设置是否启用从相册获取二维码。 // intent.putExtra(Constant.EXTRA_IS_ENABLE_SCAN_FROM_PIC,true);**   ### **从照片获取二维码的效果如下：** ### ![image](https://github.com/MRYangY/YZxing/blob/master/app/src/main/res/effect-picture/scan_form_pic_%20effect.gif) ## **觉得还不错的就动动手指给个star吧(*^__^*)** ##   ## **关于二维码功能的分析请移步至文章** ## https://blog.csdn.net/qq_34902522/column/info/28769 ================================================ FILE: YZxing-lib/.gitignore ================================================ /build ================================================ FILE: YZxing-lib/build.gradle ================================================ apply plugin: 'com.android.library' apply plugin: 'com.jfrog.bintray' apply plugin: 'com.github.dcendents.android-maven' def siteUrl = 'https://github.com/MRYangY/YZxing' // 项目的主页 def gitUrl = 'https://github.com/MRYangY/YZxing.git' // Git仓库的url Properties properties = new Properties() properties.load(project.rootProject.file('local.properties').newDataInputStream()) version = "2.2" //发布版本号 group = "com.yangy" //最终引用形式，如compile 'com.yangy.lfilepicker:1.0.0'，其中lfilepicker在后面配置 android { compileSdkVersion 26 buildToolsVersion "25.0.3" defaultConfig { minSdkVersion 19 targetSdkVersion 26 versionCode 1 versionName "1.0" testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner" } buildTypes { release { minifyEnabled false proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro' } } } 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-v7:26.+' compile 'com.android.support.constraint:constraint-layout:1.0.2' testCompile 'junit:junit:4.12' compile 'com.google.zxing:core:3.3.0' } bintray { user = properties.getProperty("bintray.user") key = properties.getProperty("bintray.apikey") pkg { repo = 'YZXing'//自己创建的仓库名字 name = 'yzxing'//上传到JCenter的名字,最终引用的名字 websiteUrl = siteUrl vcsUrl = gitUrl licenses = ['Apache-2.0']//不能随便写，只能是仓库创建时选择的license type userOrg = 'yangyulibrary' //自己创建的organization名称 publish = true // 是否是公开项目，公开别人可以引用 version { name = '2.2' desc = '基于zxing的扫码库，样式类似于微信扫一扫'//描述，自己定义 released = new Date() vcsTag = 'v2.2' attributes = ['gradle-plugin': 'com.use.less:com.use.less.gradle:gradle-useless-plugin'] } } configurations = ['archives'] } install { repositories.mavenInstaller { // This generates POM.xml with proper parameters pom { project { packaging 'aar' // Add your description here name 'yangy Android' description 'yangy open library.' url siteUrl // Set your license licenses { license { name 'Apache-2.0' //和之前自己定义的协议一致 url 'https://raw.githubusercontent.com/minggo620/Pluto-Android/master/LICENSE' } } developers { developer { id 'mryangy423' //填写bintray或者github的用户名 name 'mryangy423' //姓名 email 'mryangy423@gmail.com'//邮箱 } } scm { connection gitUrl developerConnection gitUrl url siteUrl } } } task sourcesJar(type: Jar) { from android.sourceSets.main.java.srcDirs classifier = 'sources' } task javadoc(type: Javadoc) { failOnError false //必须添加以免出错 source = android.sourceSets.main.java.srcDirs classpath += project.files(android.getBootClasspath().join(File.pathSeparator)) } task javadocJar(type: Jar, dependsOn: javadoc) { classifier = 'javadoc' from javadoc.destinationDir } artifacts { archives javadocJar archives sourcesJar } javadoc { options{ //如果你的项目里面有中文注释的话，必须将格式设置为UTF-8，不然会出现乱码 encoding "UTF-8" charSet 'UTF-8' author true version true links "http://docs.oracle.com/javase/7/docs/api" } } } } ================================================ FILE: YZxing-lib/proguard-rules.pro ================================================ # Add project specific ProGuard rules here. # By default, the flags in this file are appended to flags specified # in /Users/yangyu/Library/Android/sdk/tools/proguard/proguard-android.txt # You can edit the include path and order by changing the proguardFiles # directive in build.gradle. # # For more details, see # http://developer.android.com/guide/developing/tools/proguard.html # Add any project specific keep options here: # If your project uses WebView with JS, uncomment the following # and specify the fully qualified class name to the JavaScript interface # class: #-keepclassmembers class fqcn.of.javascript.interface.for.webview { # public *;
