是否可以将网络呼叫超时设置为60秒以上。

改装2是可能的。请尝试下面的代码

int timeOut = 3 * 60; // duration in seconds
    OkHttpClient client = new OkHttpClient.Builder()
            .connectTimeout(timeOut, TimeUnit.SECONDS)
            .writeTimeout(timeOut, TimeUnit.SECONDS)
            .readTimeout(timeOut, TimeUnit.SECONDS)
            .build();

    Retrofit retrofit = new Retrofit.Builder()
            .baseUrl("your netwrok url")
            .addConverterFactory(GsonConverterFactory.create())
            .client(client)
            .build();

YourRetrofitInterface service = retrofit.create(YourRetrofitInterface.class);
