android - 如何在android list 中连接字符串资源和构建变量

Question

前提:我想本地化 App 名称(使用字符串资源)
同时从 gradle 文件添加构建类型后缀(“DEBUG”)。

我在这里尝试连接字符串资源“app_name”和 gradle 变量“AppNameSuffix”

Expected app name :
for product flavor "all" - "My application DEBUG"
for product flavor "china" - "My Chinese application DEBUG"
and subsequent build type suffixed for "RELEASE" and "CANARY"

---

build.gradle:

buildTypes {
    debug {
        manifestPlaceholders = [AppNameSuffix: "DEBUG"]
        ...
    }
    release{
        manifestPlaceholders = [AppNameSuffix: "RELEASE"]
        ...
    }
    canary{
        manifestPlaceholders = [AppNameSuffix: "CANARY"]
    }
}
productFlavors {
    china {
        applicationId "com.myapplication.china"
    }
    all {
        //default
        applicationId "com.myapplication.all"
    }
}

---

list :

<application
    ...
    android:label="@{@string/app_name(${AppNameSuffix})}">
    ...
</application>

评估gradle变量时在“$”符号处出错

---

主/res/string.xml :

<string name="app_name">My application %s</string>

---

中国/res/string.xml :

<string name="app_name">My Chinese application %s</string>

在您的 gradle 文件中，使用小写字母以便资源名称有效:

buildTypes {
    debug {
        manifestPlaceholders = [AppNameSuffix: "_debug"]
        ...
    }
    release{
        manifestPlaceholders = [AppNameSuffix: "_release"]
        ...
    }
    canary{
        manifestPlaceholders = [AppNameSuffix: "_canary"]
    }
}

修改您的 list :有括号要删除，如果还没有的话，可能要添加 tools:replace:

<application
    ...
    android:label="@string/app_name${AppNameSuffix}"
    tools:replace="android:label"
    ...
</application>

然后你需要添加匹配你的后缀的字符串资源:

<string name="app_name">My application</string>
<string name="app_name_debug">My application DEBUG</string>
<string name="app_name_release">My application RELEASE</string>
<string name="app_name_canary">My application CANARY</string>

您还可以尝试各种风格，并将特定的 strings.xml 文件放入与您的风格相匹配的文件夹中。
