构建口味的不同版本的同一类的 [英] Build flavors for different version of same class

问题描述

我有一个项目，结构是这样的：

I've got a project, structured like this:

project/
   |
   |---src/
        |---flavorA2/
        |      |
        |      |---java/
        |      |     |---com.abc.flavorA.mk2
        |      |                 |-----classA.java
        |      |                 |-----classB.java
        |      |---res/
        |      |---AndroidManifest.xml
        |
        |---main
        |      |---java/
        |      |     |---com.abc.flavorA
        |      |                 |-----classA.java
        |      |                 |-----classB.java
        |      |                 |-----classC.java
        |      |                 |-----classD.java
        |      |---res/
        |      |    |---drawable/
        |      |    |---layout/
        |      |    |---values/
        |      |         
        |      |---AndroidManifest.xml
        |
        |---flavorA

flavorA 将使用主完全而 flavorA2 有一些小的修改 CLASSA 和 CLASSB 和包名称也更改为 com.abc.flavorA.mk2 。

flavorA will use the source and assets from main completely while flavorA2 has some small changes in classA and classB and the package name is also changed to com.abc.flavorA.mk2.

我有 build.gradle 文件是这样的：

...
buildTypes {
        release {
            runProguard false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.txt'
        }
    }
    productFlavors {
        flavorA2 {
            packageName "com.abc.flavorA.mk2"
            versionCode 2
            versionName "1.0.1"
        }

        flavorA {
            packageName "com.abc.flavorA"
        }
    }
...

我选择了构建变量以 flavorA2 运行code。然而，运行结果表明，摇篮仍然选择了类（ CLASSA 和 CLASSB ）从而是采用了更改版本内 flavorA2 主。

I run the code by selecting the build variant to flavorA2. However the running results shows that the gradle still choose the classes (classA and classB) from main instead of using the changed version inside flavorA2.

我失去了一些东西呢？

推荐答案

既然你已经在2个不同的包中的类，这是完全不同的类别。因此，类不是取代对方。

Since you have the classes under 2 different packages, these are totally different classes. So the classes aren't replacing each other.

使用香精，不能覆盖类文件。因此，一种方式来完成你想要的是将这些类出主，并进入 flavorA 。

With flavors, you can't override class files. So, one way to accomplish what you want is move these classes out of main, and into flavorA.

所以，你会是这样的：

project/
   |
   |---src/
        |---flavorA2/
        |      |
        |      |---java/
        |      |     |---com.abc
        |      |                 |-----classA.java
        |      |                 |-----classB.java
        |      |---res/
        |      |---AndroidManifest.xml
        |
        |---main
        |      |---java/
        |      |     |---com.abc.flavorA
        |      |                 |-----classC.java
        |      |                 |-----classD.java
        |      |---res/
        |      |    |---drawable/
        |      |    |---layout/
        |      |    |---values/
        |      |         
        |      |---AndroidManifest.xml
        |
        |---falvorA
        |      |---java/
        |      |     |---com.abc
        |      |                 |-----classA.java
        |      |                 |-----classB.java

这样一来，只要你选择一个味道，ClassA和ClassB的只有一个版本将是可见的。

This way, whenever you pick a flavor, only one version of ClassA and ClassB will be visible.
