如何将JSON文件添加到我的项目中

将JSON文件添加到应用

推荐答案

我想简单地将其移至应用程序下

I want to simply move it over under app

如果从字面上讲您想拥有app/something.json，欢迎将文件放在此处，但该文件不会与您的应用打包在一起，并且在运行时将不可用.

If you literally mean that you want to have app/something.json, you are welcome to put the file there, but it will not be packaged with your app, and it will not be available to you at runtime.

如果您希望将JSON与您的应用一起发布，则有四个主要选择:

If you want to ship the JSON with your app, you have four major options:

• 将其放入assets/中，并使用AssetManager及其open()方法读取以获取InputStream

• Put it in assets/ and read it in using AssetManager and its open() method to get an InputStream

将其放入res/raw/中，并使用Resources及其openRawResource()方法读取它

Put it in res/raw/ and read it in using Resources and its openRawResource() method

使用Java代码将其硬编码为字符串

Hardcode it as a string in Java code

为自己编写一个代码生成器，该代码生成器将JSON转换为您可以访问的Java类，就像执行代码生成的R和BuildConfig类

Write yourself a code generator that converts JSON into a Java class that you would access like you do the code-generated R and BuildConfig classes

这样的代码生成器可能已经存在.我有一个基本的Gradle插件，例如我将包含在我的书的下一次更新中.

It is possible that such a code generator already exists. I have a rudimentary Gradle plugin that does this, as an example that I'll be including in the next update of my book.
