无法以编程方式从另一个模块获取资源 [英] Can't programmatically get resource from another module

问题描述

我有一个带有多个gradle模块的android项目.模块之间的依存关系如下所示:
应用<-核心模块<-功能模块

I have an android project with several gradle modules. Dependencies beetween modules look like this:
app <-- coremodule <-- featuremodule

coremodule中有资源(字符串和颜色).

There are a resources in coremodule (strings and colors).

当我在Featuremodule的布局中使用它们时，一切正常，它们可用并且可以按预期工作.但是，当我尝试通过功能模块从Activity中以编程方式获取它们时，出现异常:未解析的引用:R

When I use them in layout from featuremodule everything is OK, they are avaliable and work as expected. But when I try to get them programmaticully in Activity from featuremodule I get an exception: Unresolved reference: R

所以 android:text ="@ string/res_from_core_module" 有效和 myTextView.setText(R.string.res_from_core_module) 不起作用.

有人知道为什么会发生这种情况以及如何解决吗?

Have anyone ideas why it happens and how to solve this?

推荐答案

这种行为的原因是通过 compileOnly 添加了"coremodule"依赖项.

The reason for such behavior was adding 'coremodule' dependency with compileOnly.

build.gradle如下:

build.gradle for app module looked like:

dependencies {
    ...
    compileOnly project(path: ':coremodule')
    ...
}

如果使用实现(或API)更改仅编译，一切正常

if change compileOnly with implementation (or api) everything is OK

dependencies {
    ...
    implementation project(path: ':coremodule')
    ...
}
