1.创建public.xml

public.xml

2.创建public-xml.gradle

工程目录结构：

完整public-xml.gradle如下：

import org.gradle.util.GFileUtilsapply plugin: PublicPluginclass PublicPlugin implements Plugin {    void apply(Project project) {        project.afterEvaluate {            if (project.plugins.hasPlugin("com.android.application")) {                def android = project.extensions.getByName("android")                def aaptOptions = android.aaptOptions                android.applicationVariants.all {def variant ->                    project.logger.error "xxxxx ${variant.name.capitalize()}"//       def processResourcesTask = project.tasks.getByName("process${variant.name.capitalize()}Resources")                    project.logger.error "xxxxx ${aaptOptions}"                    if (aaptOptions) {//                        def aaptOptions = processResourcesTask.aaptOptions                        File publicTxtFile = project.rootProject.file('generate_public.txt')                        //public文件存在，则应用，不存在则生成                        if (publicTxtFile.exists()) {                            project.logger.error "${publicTxtFile} exists, apply it."                            //aapt2添加--stable-ids参数应用                            aaptOptions.additionalParameters("--stable-ids", "${publicTxtFile}")                        } else {                            project.logger.info "${publicTxtFile} not exists, generate it."                            //aapt2添加--emit-ids参数生成                            aaptOptions.additionalParameters("--emit-ids", "${publicTxtFile}")                        }                    }                }            }        }    }}task convertPublicXmlToPublicTxt(){    project.logger.error "start convertPublicXmlToPublicTxt"//源public.xml    File publicXmlFile = project.rootProject.file('app/src/main/res/values/public.xml')//目标public.txt    File publicTxtFile = project.rootProject.file('generate_public.txt')//包名    String applicationId = "com.geniatech.oobe"    GFileUtils.deleteQuietly(publicTxtFile)    GFileUtils.touch(publicTxtFile)    def nodes = new XmlParser().parse(publicXmlFile)//        Pattern drawableGeneratePattern = Pattern.compile('^(.*?_)([0-9]{0,})$')    nodes.each {        project.logger.error "${it}"/*            if ("drawable".equalsIgnoreCase("${it.@type}")) {//以'_数字'结尾的drawable资源，此类资源是aapt编译时生成的nested资源，如avd_hide_password_1, avd_hide_password_2//但是可能会有其他资源掺杂，如abc_btn_check_to_on_mtrl_000, abc_btn_check_to_on_mtrl_015//为了将此类资源过滤掉，将正则匹配到的数字转成int，对比原始数字部分匹配字符串，如果一致，则是aapt生成//重要：为了避免此类nested资源生成顺序发生改变，应该禁止修改此类资源//aapt生成的是以下表1开始，aapt2是以下标0开始，因此转换的过程需要-1                Matcher matcher = drawableGeneratePattern.matcher(it.@name)                if (matcher.matches() && matcher.groupCount() == 2) {                    String number = matcher.group(2)                    if (number.equalsIgnoreCase(Integer.parseInt(number).toString())) {                        String prefixName = matcher.group(1)                        publicTxtFile.append("${applicationId}:${it.@type}/\$${prefixName}_${Integer.parseInt(number) - 1} = ${it.@id}\n")                        return                    }                }            }*/        publicTxtFile.append( "${applicationId}:${it.@type}/${it.@name} = ${it.@id}\n")    }    doFirst{        project.logger.error 'convertPublicXmlToPublicTxt doFirst'    }    doLast {        project.logger.error 'convertPublicXmlToPublicTxt doLast'    }}

3.引入我们的public-xml.gradle和在根build.gradle中自动触发task convertPublicXmlToPublicTxt

this.afterEvaluate { Project project ->    project.logger.error "start afterEvaluate"    tasks.matching {        project.logger.error "test task ${it.name}"        it.name.startsWith('wrapper')    }.each { task ->        task.dependsOn(convertPublicXmlToPublicTxt)    }}

android 自定义资源id，aapt2，public.xml,支持最新gradle 5.4.1
