方案適用背景

1. 一套代碼出多個安裝包，且安裝包的應用名稱、圖標都不一樣
2. 考慮三語名稱問題

通過 Gradle 腳本實現

gradle.properties 里面定義標識來區分應用，如下文里的 APP_TYPE=AAA
、APP_TYPE=BBB

// 定義 groovy 替換方法
def replaceAppName(String filePath) {File xmlFile = file(filePath)XmlSlurper slurp = new XmlSlurper()def xmlText = xmlFile.textdef resources = slurp.parseText(xmlText)def app_name = '',app_name_aaa = '',app_name_bbb = ''resources.string.each {if (it.@name == 'app_name_aaa') {app_name_aaa = it.text()} else if (it.@name == 'app_name_bbb') {app_name_bbb = it.text()}if (APP_TYPE == 'AAA') {app_name = app_name_bbb}if (APP_TYPE == 'BBB') {app_name = app_name_aaa}}resources.string.each {if (it.@name == 'app_name') {it.replaceBody(app_name)return}}def modifiedXmlString = XmlUtil.serialize(resources)xmlFile.withWriter { writer ->writer.write(modifiedXmlString)writer.flush()writer.close()}
}

修改資源文件

• res/values/strings.xml
• res/values-zh/strings.xml
• res/values-tw/strings.xml

資源文件內容

<!-- res/values/strings.xml 其他多語言文案類似配置 -->
<?xml version="1.0" encoding="UTF-8"?><resources><string name="app_name"></string><string name="app_name_aaa">生活</string><string name="app_name_bbb">工作</string>
</resources>  

創建替換 Task

//定義 gradle task
task switchApp {doLast {replaceAppName("src/main/res/values/strings.xml")replaceAppName("src/main/res/values-zh/strings.xml")replaceAppName("src/main/res/values-tw/strings.xml")}
}//將任務依賴到 gradle 的“編譯前”生命周期task里面, 這樣每次編譯之前就會自動執行這個任務
preBuild.dependsOn switchApp
