How to implement a new Dialog error in Android Studo (JAVA)

问题

以下是要翻译的代码部分：

So here is the status code for the errors. Not sure if the codes are random or not (I didn't make this project)

    public class StatusCodeUtil {
    
        public static final int AWS_GATEWAY_ERROR = 1;
        public static final int URL_INVALID = 2;
        public static final int INTERNAL_SERVER_ERROR = 14;
        public static final int ENDPOINT_INFO_STORAGE_INCOMPLETE = 7;
        public static final int NO_PERMISSION_GET_DEVICE_ID = 8;
        public static final int INVALID_API_FUNCTION = 18;
        public static final int INVALID_HTTP_STATUS_CODE = -1;
        public static final int NO_NETWORK_ERROR = 3; <- This is the status code I want to work
    } 

Here is the Callback for the errors

    public abstract class  ApiCallBack<T> implements Callback<ApiResponse<T>> {
    
        private ParabitSDKBeaconApplication application;
    
        public ApiCallBack(ParabitSDKBeaconApplication application) {
            this.application = application;
        }
    
        @Override
        public void onResponse(Call<ApiResponse<T>> call, Response<ApiResponse<T>> response) {
            Long roundTripTime = getRoundTripTime(response);
    
            if (response.isSuccessful()) {
                ApiResponse<T> responseBody = response.body();
                onApiResponse(responseBody.getMessage(), response.code(), responseBody.getData());
            } else {
                /**
                 * error level 1 (HTTP client or gateway error)
                 * */
                String errorBodyJson = getErrorBodyStr(response);
                // can not user ApiResponse<T> to catch the json here
                // will lead to exception: java.lang.AssertionError: illegal type variable reference
                // no good way to solve this (Gson's problem)
                ApiErrorResponse errorBody = GsonUtil.jsonStrToObject(errorBodyJson,
                        new TypeToken<ApiErrorResponse>(){});
    
                if (errorBody.getMessage().equalsIgnoreCase("forbidden")) { // x-api-key invalid
                    if (getLogControlManager().isLog()) {
                        Log.e(PARABIT_SDK_LOG, "AWS Gateway Error: " + errorBody.getMessage());
                    }
    
                    onError(new ApiErrorCodeInfo(AWS_GATEWAY_ERROR, response.code(),
                            errorBody.getMessage()));
                } else if (errorBody.getMessage().equalsIgnoreCase(
                        "missing authentication token")) {
                    if (getLogControlManager().isLog()) {
                        Log.e(PARABIT_SDK_LOG, "AWS Gateway Error: " + errorBody.getMessage());
                    }
                    onError(new ApiErrorCodeInfo(INVALID_API_FUNCTION, response.code(),
                            errorBody.getMessage()));
                } else {
                    if (getLogControlManager().isLog()) {
                        Log.e(PARABIT_SDK_LOG, "Other Error Response: " + errorBody.getMessage());
                    }
                    // should never happen for now
                    onError(new ApiErrorCodeInfo(INTERNAL_SERVER_ERROR, response.code(),
                            errorBody.getMessage()));
                }
            }
        }
    
        @Override
        public void onFailure(Call<ApiResponse<T>> call, Throwable t) {
            /**
             * error level 1 (HTTP client or gateway error)
             * */
            if (t instanceof UnknownHostException) { // host of end point is unknown
                if (getLogControlManager().isLog()) {
                    Log.e(PARABIT_SDK_LOG, "onFailure: " + "UnknownHostException");
                }
                onError(new ApiErrorCodeInfo(URL_INVALID, t.getLocalizedMessage()));
            } else {
                if (getLogControlManager().isLog()) {
                    Log.e(PARABIT_SDK_LOG, "onFailure: " + t.getLocalizedMessage());
                }
                onError(new ApiErrorCodeInfo(INTERNAL_SERVER_ERROR,
                        t.getLocalizedMessage()));
            }
        }
    
        public static<T> String getErrorBodyStr(Response<ApiResponse<T>> response) {
            if (response.errorBody() == null) {
                return "";
            }
    
            String errorBodyStr = "";
            try {
                errorBodyStr = response.errorBody().string();
            } catch (IOException e) {
                e.printStackTrace();
            }
            return errorBodyStr;
        }
    
        protected Long getRoundTripTime(Response response) {
            Long roundTripTime = response.raw().sentRequestAtMillis()
                    - response.raw().receivedResponseAtMillis();
            return roundTripTime;
        }
    
    //    public abstract void onSuccess(String successMsg, List<T> data);
        public abstract void onApiResponse(String ApiMsg, int httpStatusCode, List<T> data);
        public abstract void onError(ApiErrorCodeInfo apiErrorCodeInfo);
    
        protected LogControlManager getLogControlManager() {
            return SdkApplicationInstance.getSdkLogControlManager(application);
        }
    }

 The code in the Activity that controls which error is shown

      loginViewModel.loginStatusInfo.observe(this, loginStatusInfo -&gt; {
                if (loginStatusInfo.getStatus() == API_SUCCESS_STATUS){
                    hideLoadingDialog();
                    startHomeActivity();
                }else if (loginStatusInfo.getStatus() == INTERNAL_SERVER_ERROR) {
                    hideLoadingDialog();
                    loginErrorDialog(getString(R.string.fail_to_login_server_error));
                }else if(loginStatusInfo.getStatus() == NO_NETWORK_ERROR){&lt;- I added this else if
                    hideLoadingDialog();
                    loginErrorDialog(getString(R.string.network_require_msg));
                }
                else {
                    hideLoadingDialog();
                    loginErrorDialog(loginStatusInfo.getMessage());
                }
            });

希望对你有所帮助。

So I want to add a dialog message to my app. There already an option for other types of error's. I just want to add an error for when there's no mobile data and WiFi. It's an older app, so it's taking me a bit more to understand, but here's what I got.

So here is the status code for the errors. Not sure if the codes are random or not (I didn't make this project)

public class StatusCodeUtil {
public static final int AWS_GATEWAY_ERROR = 1;
public static final int URL_INVALID = 2;
public static final int INTERNAL_SERVER_ERROR = 14;
public static final int ENDPOINT_INFO_STORAGE_INCOMPLETE = 7;
public static final int NO_PERMISSION_GET_DEVICE_ID = 8;
public static final int INVALID_API_FUNCTION = 18;
public static final int INVALID_HTTP_STATUS_CODE = -1;
public static final int NO_NETWORK_ERROR = 3; &lt;- This is the status code I want to work
}

Here is the Callback for the errors

public abstract class  ApiCallBack&lt;T&gt; implements Callback&lt;ApiResponse&lt;T&gt;&gt; {

hideLoadingDialog();
loginErrorDialog(getString(R.string.fail_to_login_server_error));
}else if(loginStatusInfo.getStatus() == NO_NETWORK_ERROR){&lt;- I added this else if
hideLoadingDialog();
loginErrorDialog(getString(R.string.network_require_msg));
}
else {
hideLoadingDialog();
loginErrorDialog(loginStatusInfo.getMessage());
}
});

Any help will be appreciated, Thank you.

So I actually called ConectivityManager on the loginViewModel.loginStatusInfo method and it worked.

loginViewModel.loginStatusInfo.observe(this, loginStatusInfo -> {
if (loginStatusInfo.getStatus() == API_SUCCESS_STATUS) {
hideLoadingDialog();
startHomeActivity();
} else if (loginStatusInfo.getStatus() == INTERNAL_SERVER_ERROR) {
hideLoadingDialog();
loginErrorDialog(getString(R.string.fail_to_login_server_error));
} else if (ConnectivityManager.TYPE_MOBILE == 0) {
hideLoadingDialog();
networkErrorDialog(getString(R.string.network_require_msg));
} else {
hideLoadingDialog();
loginErrorDialog(loginStatusInfo.getMessage());
}
});
