如果没有响应，应用程序将在此行崩溃。

optionsArray : Array<{productOptionId : string , productOptionValueId : string}> = [];

这是我的RetrofitClient课程

chain.proceed(requestBuilder.build())

这是日志中的错误：

class RetrofitClient {

    private val apiService: ApiServiceInterface

    init {
        val builder = Retrofit.Builder()
        builder.baseUrl(RequestParameters.BASE_URL)
        builder.addConverterFactory(GsonConverterFactory.create())
        builder.addCallAdapterFactory(RxJava2CallAdapterFactory.create())//added for adapter
        builder.client(getClient())
        val retrofit = builder.build()
        apiService = retrofit.create(ApiServiceInterface::class.java)
    }

    companion object {
        private var clientInstance: RetrofitClient? = null
        lateinit var context: Context

        fun getInstance(): RetrofitClient {
            if (clientInstance == null) {
                clientInstance = RetrofitClient()
            }
            return clientInstance as RetrofitClient
        }
    }

    fun getApiInterface(): ApiServiceInterface {
        return apiService
    }

    private fun getClient(): OkHttpClient {

        val httpClient = OkHttpClient.Builder()
        httpClient.readTimeout(25, TimeUnit.SECONDS)
        httpClient.connectTimeout(25, TimeUnit.SECONDS)

        httpClient.addInterceptor { chain ->
            val original = chain.request()

            val requestBuilder = original.newBuilder()
                    .header(RequestParameters.X_API, RequestParameters.H_XAPI_KEY)
                    .method(original.method(), original.body())

            chain.proceed(requestBuilder.build())
        }

        // set your desired log level
        val logging = HttpLoggingInterceptor()
        logging.level = HttpLoggingInterceptor.Level.HEADERS
        logging.level = HttpLoggingInterceptor.Level.BODY
        httpClient.addInterceptor(logging)

        return httpClient.build()
    }
}

尝试这种代码方式。成为改造对象创建的一部分。

interface ApiInterface {
@GET("marvel")
fun getData(): Call<List<Hero>>

}

用于api调用的make接口。

var apiInterface: ApiInterface = ApiClient.getClient()!!.create(ApiInterface::class.java)
    var hero: Call<List<Hero>>
    hero = apiInterface.getData()
    hero.enqueue(object : Callback<List<Hero>> {
        override fun onFailure(call: Call<List<Hero>>?, t: Throwable?) {
            closeDialog(dialog)
            Toast.makeText(mContext, t?.message, Toast.LENGTH_SHORT).show()
            Log.d("Error:::",t?.message)
        }

        override fun onResponse(call: Call<List<Hero>>?, response: Response<List<Hero>>?) {
           mHeroDataList.clear()
            if (response != null && response.isSuccessful && response.body() != null) {
                closeDialog(dialog)
                mHeroDataList .addAll(response.body()!!)
                setAdapter(mHeroDataList)
            }
        }

    })

}

像这样，在活动或称为api的片段中，我希望您创建响应pojo类

public class GradientTextView extends AppCompatTextView {
        public GradientTextView(Context context) {
            super(context);

        }
        public GradientTextView(Context context, AttributeSet attrs) {
            super(context, attrs);
            TypedArray a=context.obtainStyledAttributes(attrs,R.styleable.GradientTextView);
            int startColor = a.getColor(R.styleable.GradientTextView_startColor, Color.WHITE);
            int endColor = a.getColor(R.styleable.GradientTextView_endColor, Color.WHITE);
            Shader myShader = new LinearGradient(0, 0, 0, 100,startColor, endColor, Shader.TileMode.CLAMP);
            this.getPaint().setShader(myShader);
            a.recycle();
        }  

        public void setCustomColor(int startColor,int endColor){
            Shader myShader = new LinearGradient(0, 0, 0, 100,startColor, endColor, Shader.TileMode.CLAMP);
            this.getPaint().setShader(myShader);
            invalidate();
        }
    }

要解决此问题，您需要确保检查设备上的网络连接，并确保在进行网络呼叫之前已建立有效的Internet连接。发出网络请求之前检查Internet连接的方法您可以像这样使用连接管理器

CamapaignActionField

这是从this answer中剔除而来的，您可以通过它检查网络的可用性。如果您想更准确地监视网络是否处于活动状态，可以尝试在Google处对Checking network on Android DNS服务器执行ping操作。
