問題描述

我有一個項目，結構如下:

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 將完全使用 main 中的源和資產，而 flavorA2 在 classA 中有一些小的變化，并且classB，包名也改為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.

我有這樣的 build.gradle 文件:

...
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"
        }
    }
...

我通過選擇 flavorA2 的構建變體來運行代碼.但是運行結果顯示，gradle 仍然從 main 中選擇類(classA 和 classB)，而不是使用 中的更改版本風味A2.

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.

我錯過了什么嗎?

推薦答案

因為你有 2 個不同包下的類，所以它們是完全不同的類.所以這些類不會互相替換.

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

使用風味，您不能覆蓋類文件.因此，實現您想要的一種方法是將這些類移出 main，并移入 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.

所以你會有這樣的東西:

So you would have something like this:

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
        |
        |---flavorA/
        |      |---java/
        |      |     |---com.abc
        |      |                 |-----classA.java
        |      |                 |-----classB.java

這樣，每當您選擇一種風味時，只會看到 ClassA 和 ClassB 的一個版本.

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