在Android Studio中添加类的文件夹的位置？ [英] Where to add folder of classes in Android Studio?

问题描述

我想在不同于活动的文件夹中设置类。
当前文件夹结构：

I want to set up classes in different folders than activities. Current folder structure:

-> APP
  -> Manifests
  -> Java
     -> com.test.testing
        -> classes
            auth.java
        home_activity
     -> libs

auth.java

package com.test.testing;
// error here: Package name ‘com.test.testing’ does not correspond to file path.
public class auth{

  public void auth(){}
}

另外，我无法在活动中调用此类：

Plus, I can't call this class in activity:

import classes.auth;

所以我去构建gradle这是我的配置：

So I went to build gradle an this are my configurations:

apply plugin: 'com.android.application'

android {
    compileSdkVersion 21
    buildToolsVersion "21.1.2"

    defaultConfig {
        applicationId "com.test.testing"
        minSdkVersion 15
        targetSdkVersion 21
        versionCode 1
        versionName "1.0"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
    sourceSets {
        main {
            java.srcDirs = ['src/main/java', 'java/', 'src/main/java/com/test/testing/classes']
            assets.srcDirs = ['src/main/assets', 'src/main/assets/']
        }
    }
}

Android Studio是李关于文件夹结构有点混乱，我们有几个选项可供选择，我不知道它们中的一些是什么。
在我的例子中，我将文件夹classes添加为Java Folder。

Android Studio is a little bit confusing about folder structures, we have several options to chose and I have no clue what some of them do. In my case, I added the folder "classes" as "Java Folder".

编辑1：
提示是创建一个包而不是一个文件夹。
所以我创建了包和一个新文件。自动，android studio将此信息填入 auth.java ;

package com.test.testing.classes;

public class auth {

}

会发生什么事情，我仍然无法将课程导入活动。
当我开始输入时（在活动中）导入类它出现在文档帮助中，但它没有任何关联的对象，它说：

What happens is that I'm still unable to import the class into the activities. Althought when I start typing (in the activity) import classes it appears as a documentation help but it doesn't have any object associated, that said:

import classes.auth; 

给出错误。

我又来了构建Gradle文件并且它没有向 java.srcDirs 添加任何内容：

I went again to build Gradle file and it didn't add anything to the java.srcDirs:

 sourceSets {
        main {
            java.srcDirs = ['java/', 'src/main/java']
        }
    }

编辑2：
导入的解决方案问题是字符串。
而不是

EDIT 2: The solution to the import problem was the string. Instead of

import classes.auth;

应该是：

import com.test.testing.classes.auth;
