问题

我的应用程序应该从CoinGecko API显示数据，以下是我尝试过的代码，但无法使其正常工作。

API服务：

  1. public class CoinGeckoService {
  2.     public static final String COINGECKO_GLOBAL_URL = "https://api.coingecko.com/api/v3/global";
  4.     private static AsyncHttpClient client = new AsyncHttpClient();
  6.     public static void getGlobalData(AsyncHttpResponseHandler responseHandler) {
  7.         List<NameValuePair> params = new ArrayList<>();
  8.         try{
  9.             URIBuilder query = new URIBuilder(COINGECKO_GLOBAL_URL);
  10.             query.addParameters(params);
  11.             client.get(query.toString(), responseHandler);
  12.         }
  13.         catch (URISyntaxException e){
  14.             Log.e("URISyntaxException", e.getMessage());
  15.         }
  16.     }
  17. }

模型：

  1. public class GlobalData implements Parcelable {
  2.     private String total_market_cap;
  3.     private String active_cryptocurrencies;
  4.     private String markets;
  5.     private String total_volume;
  6.     private String market_cap_percentage;
  8.     public GlobalData(Parcel in){
  9.         String[] data = new String[5];
  11.         in.readStringArray(data);
  12.         this.total_market_cap = data[0];
  13.         this.active_cryptocurrencies = data[1];
  14.         this.markets = data[2];
  15.         this.total_volume = data[3];
  16.         this.market_cap_percentage = data[4];
  17.     }
  19.     @Override
  20.     public int describeContents() {
  21.         return 0;
  22.     }
  24.     public static final Parcelable.Creator<GlobalData> CREATOR = new Parcelable.Creator<GlobalData>() {
  25.         @Override
  26.         public GlobalData createFromParcel(Parcel source) {
  27.             return new GlobalData(source);
  28.         }
  29.         @Override
  30.         public GlobalData[] newArray(int size) {
  31.             return new GlobalData[size];
  32.         }
  33.     };
  35.     @Override
  36.     public void writeToParcel(Parcel dest, int flags) {
  37.         dest.writeStringArray(new String[]{
  38.                 this.total_market_cap,
  39.                 this.active_cryptocurrencies,
  40.                 this.markets,
  41.                 this.total_volume,
  42.                 this.market_cap_percentage
  43.         });
  44.     }
  46.     public String getTotalMarketCap() {
  47.         return total_market_cap;
  48.     }
  50.     public String getActiveCurrencies() {
  51.         return active_cryptocurrencies;
  52.     }
  54.     public String getMarkets() {
  55.         return markets;
  56.     }
  58.     public String getTotalVolume() {
  59.         return total_volume;
  60.     }
  62.     public String getMarketCapPercent() {
  63.         return market_cap_percentage;
  64.     }
  65. }

最后，在我的片段中有这个方法：

  1. public void getGlobalData() {
  3.     CoinGeckoService.getGlobalData(new JsonHttpResponseHandler() {
  4.         @Override
  5.         public void onSuccess(int statusCode, Header[] headers, JSONArray response) {
  6.             GlobalData[] result = new Gson().fromJson(response.toString(), GlobalData[].class);
  8.             for (GlobalData node : result) {
  9.                 marketCapData.setText(node.getTotalMarketCap());
  10.                 Log.d("response_", "" + node.getTotalMarketCap());
  11.             }
  12.             swipeRefreshLayout.setRefreshing(false);
  13.         }
  15.         @Override
  16.         public void onFailure(int statusCode, Header[] headers, Throwable throwable, JSONObject response) {
  17.             swipeRefreshLayout.setRefreshing(false);
  18.         }
  19.     });
  20. }

但是似乎不起作用，日志显示：JsonHttpRH：未覆盖onSuccess(int，Header[]，JSONArray)，但已收到回调。

这是来自API的响应数据：https://api.coingecko.com/api/v3/global

英文:

My app is supposed to show data from CoinGecko API, here's what I tried but can't get it to work.

API Service:

  1. public class CoinGeckoService {
  2. public static final String COINGECKO_GLOBAL_URL = &quot;https://api.coingecko.com/api/v3/global&quot;;
  3. private static AsyncHttpClient client = new AsyncHttpClient();
  4. public static void getGlobalData(AsyncHttpResponseHandler responseHandler) {
  5. List&lt;NameValuePair&gt; params = new ArrayList&lt;&gt;();
  6. try{
  7. URIBuilder query = new URIBuilder(COINGECKO_GLOBAL_URL);
  8. query.addParameters(params);
  9. client.get(query.toString(), responseHandler);
  10. }
  11. catch (URISyntaxException e){
  12. Log.e(&quot;URISyntaxException&quot;, e.getMessage());
  13. }
  14. }
  15. }

Model:

  1. public class GlobalData implements Parcelable {
  2. private String total_market_cap;
  3. private String active_cryptocurrencies;
  4. private String markets;
  5. private String total_volume;
  6. private String market_cap_percentage;
  7. public GlobalData(Parcel in){
  8. String[] data = new String[5];
  9. in.readStringArray(data);
  10. this.total_market_cap = data[0];
  11. this.active_cryptocurrencies = data[1];
  12. this.markets = data[2];
  13. this.total_volume = data[3];
  14. this.market_cap_percentage = data[4];
  15. }
  16. @Override
  17. public int describeContents() {
  18. return 0;
  19. }
  20. public static final Parcelable.Creator&lt;GlobalData&gt; CREATOR = new Parcelable.Creator&lt;GlobalData&gt;() {
  21. @Override
  22. public GlobalData createFromParcel(Parcel source) {
  23. return new GlobalData(source);
  24. }
  25. @Override
  26. public GlobalData[] newArray(int size) {
  27. return new GlobalData[size];
  28. }
  29. };
  30. @Override
  31. public void writeToParcel(Parcel dest, int flags) {
  32. dest.writeStringArray(new String[]{
  33. this.total_market_cap,
  34. this.active_cryptocurrencies,
  35. this.markets,
  36. this.total_volume,
  37. this.market_cap_percentage
  38. });
  39. }
  40. public String getTotalMarketCap() {
  41. return total_market_cap;
  42. }
  43. public String getActiveCurrenices() {
  44. return active_cryptocurrencies;
  45. }
  46. public String getMarkets() {
  47. return markets;
  48. }
  49. public String getTotalVolume() {
  50. return total_volume;
  51. }
  52. public String getMarketCapPercent() {
  53. return market_cap_percentage;
  54. }
  55. }

Lastly, this method is inside my fragment:

  1.     public void getGlobalData() {
  2. CoinGeckoService.getGlobalData(new JsonHttpResponseHandler() {
  3. @Override
  4. public void onSuccess(int statusCode, Header[] headers, JSONArray response) {
  5. GlobalData[] result = new Gson().fromJson(response.toString(), GlobalData[].class);
  6. for (GlobalData node : result) {
  7. marketCapData.setText(node.getTotalMarketCap());
  8. Log.d(&quot;response_&quot;, &quot;&quot; +node.getTotalMarketCap());
  9. }
  10. swipeRefreshLayout.setRefreshing(false);
  11. }
  12. @Override
  13. public void onFailure(int statusCode, Header[] headers, Throwable throwable, JSONObject response) {
  14. swipeRefreshLayout.setRefreshing(false);
  15. }
  16. });
  17. }

But It doesn't seem to work, and log says: JsonHttpRH: onSuccess(int, Header[], JSONArray) was not overriden, but callback was received.

This is the response data from the API: https://api.coingecko.com/api/v3/global

得分: 1

以下是翻译好的部分：

尝试使用retrofit2。将以下依赖项添加到gradle中。

使用retrofit是从远程源获取数据的最佳方式。

  1. implementation 'com.squareup.retrofit2:retrofit:2.2.0'
  2. implementation 'com.squareup.retrofit2:converter-gson:2.2.0'

然后创建一个APIURL类，其中包括您的基本URL。

  1. public class APIUrl {
  2.     public static final String BASE_URL = "https://api.coingecko.com/";
  3. }

之后创建一个APIService类，其中包含您的获取参数。我的数据应该从这个网站生成。

  1. public interface APIService {
  2.     @GET("api/v3/global")
  3.     Call<MyData> getList();
  4. }

最后像这样获取您的数据。

  1. public void getData() {
  2.     Gson gson = new GsonBuilder().setLenient().create();
  3.     Retrofit retrofit = new Retrofit.Builder()
  4.         .baseUrl(APIUrl.BASE_URL)
  5.         .addConverterFactory(GsonConverterFactory.create(gson))
  6.         .build();
  8.     APIService apiService = retrofit.create(APIService.class);
  9.     Call<MyData> call = apiService.getList();
  10.     call.enqueue(new Callback<MyData>() {
  11.         @Override
  12.         public void onResponse(Call<MyData> call, Response<MyData> response) {
  13.             // 这将以MyData类型提供所有数据，您可以在此处进行操作
  14.         }
  16.         @Override
  17.         public void onFailure(Call<MyData> call, Throwable t) {
  18.             Log.d("error", t.getMessage().toString());
  19.         }
  20.     });
  21. }
英文:

try to use retrofit2.Add these dependencies into gradle.
Using retrofit is the best way for fetching data from remote source.

  1. implementation &#39;com.squareup.retrofit2:retrofit:2.2.0&#39;
  2. implementation &#39;com.squareup.retrofit2:converter-gson:2.2.0&#39;

then create an APIURL class which includes your base url

  1.   public class APIUrl {
  2. public static final String BASE_URL = &quot;https://api.coingecko.com/&quot;;
  3. }

after that create an APIService class which includes your get parameters.My data should be generated from this website.
http://www.jsonschema2pojo.org

  1. public interface APIService {
  2. @GET(&quot;api/v3/global&quot;)
  3. Call&lt;MyData&gt; getList();
  4. }

Lastly fetch your data like this.

  1.  public void getData() {
  2. Gson gson = new GsonBuilder().setLenient().create();
  3. Retrofit retrofit = new Retrofit.Builder().baseUrl(APIUrl.BASE_URL).addConverterFactory(GsonConverterFactory.create(gson)).build();
  4. APIService apiService = retrofit.create(APIService.class);
  5. Call&lt;MyData&gt; call = apiService.getData();
  6. call.enqueue(new Callback&lt;VeriListem&gt;() {
  7. @Override
  8. public void onResponse(Call&lt; MyData &gt; call, Response&lt; MyData &gt; response) {
  9. // this gives you all data as MyData type and do your operation here
  10. }
  11. @Override
  12. public void onFailure(Call&lt;MyData&gt; call, Throwable t) {
  13. Log.d(&quot;error&quot;, t.getMessage().toString());
  14. }
  15. });
  16. }
