我正在使用RetroFit拨打TheMovieDatabase API，并试图获取一个热门电影列表，以填入ArrayList。但是，当我通过RetroFit进行调用时，我收到与OkHTTP相关的错误。我正在将OkHTTP与RetroFit结合使用：
RecylerView以下是我在RetroFit中的相关代码：

我知道这个问题已经 2 年了，但我解决了我的问题。所以这是您可以尝试的替代答案。
我的错误是在升级我的依赖项版本后开始的（Android Studio 在查看项目结构后建议它）。由于问题涉及 Retrofit 和 OkHttp，当我的应用程序运行时，我恢复到我使用的旧版本。所以，我建议恢复到旧版本：
implementation 'com.squareup.retrofit2:retrofit:*older version here*'
implementation 'com.squareup.retrofit2:converter-gson:*older version here*'
implementation 'com.squareup.retrofit2:converter-moshi:*older version here*'
implementation 'oauth.signpost:oauth-signpost:*older version here*'
implementation 'se.akerfeldt:okhttp-signpost:*older version here*'
implementation 'com.squareup.okhttp3:okhttp:*older version here*'
implementation 'oauth.signpost:signpost-core:*older version here*'
这是我恢复到旧版本的依赖项。我建议您在应用运行时将任何与 Retrofit 或 OkHttp 相关的依赖项更改回旧版本。
如果您在确定可用的旧版本时遇到任何问题，我建议从 Project Structure > Dependencies 选项卡 > 查看依赖项版本应用标签。从那里您可以找到您正在寻找的依赖项，并更改版本。
祝你好运
