Comment analyser l'analyse JSON en utilisant GSON dans Android

J'utilise GSON pour analyser les données Json. Mes données Json sont ci-dessous:

{
    "count": "12",
    "colbreak": 1,
    "name": "unary rels",
    "score": "9090",
    "Words": [
        {
            "count": 6,
            "Word": "prp_għaċ-",
            "name": "prp_għaċ-",
            "score": 9.1,
            "Words": "kol",
            "seek": 2231297
        }
    ],
    "seek": 0
}

GsonParse.Java 

public class GsonParse {


 @SerializedName("count")
 public String count;

 @SerializedName("colbreak")
 public String colbreak;

 @SerializedName("name")
 public String count;
 @SerializedName("score")
 public String score;

 @SerializedName("Words")
 public List<Words> mWords = new ArrayList<Words>();

 @SerializedName("seek")
 public String seek;
}

J'utilise la méthode ci-dessous pour analyser ces données JSON.

public static <T> ArrayList<T> JsonParse(T t, String response) {
        // convert String into InputStream
        InputStream in = new ByteArrayInputStream(response.getBytes());
        JsonReader reader;
        ArrayList<T> lcs = new ArrayList<T>();
        try {
            reader = new JsonReader(new InputStreamReader(in, "UTF-8"));
            Gson gson = new Gson();

            reader.beginObject();
            while (reader.hasNext()) {

                T cse = (T) gson.fromJson(reader, t.getClass());
                lcs.add(cse);
            }

            reader.endObject();

            /*
             * reader.nextName(); reader.nextString(); reader.nextName();
             * reader.nextString();
             */
            reader.close();
        } catch (UnsupportedEncodingException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        } catch (IOException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }

        return (ArrayList<T>) lcs;
    }

Je suis confronté à l'erreur ci-dessous.

03-31 10:14:26.968: E/AndroidRuntime(18578): com.google.gson.JsonSyntaxException: Java.lang.IllegalStateException: Expected BEGIN_OBJECT but was NAME at line 1 column 73

vous pouvez essayer de lire la valeur gson comme ceci:

try {
      AssetManager assetManager = getAssets();
  InputStream ims = assetManager.open("file.txt");

  Gson gson = new Gson();
  Reader reader = new InputStreamReader(ims);

  GsonParse gsonObj = gson.fromJson(reader, GsonParse.class);

     }catch(IOException e) {
       e.printStackTrace();
 }

En supposant que vous recevez juste ce bloc et non une liste. Et aussi ces données sont actuellement dans un fichier dans le dossier des actifs. Vous pouvez le changer pour le flux que vous voulez lire.

La classe que vous utilisez devrait ressembler à ceci:

GsonParse.class 

public class GsonParse {
 @SerializedName("count")
 private String count;

 @SerializedName("colbreak")
 private String colbreak;

 @SerializedName("name")
 private String name;

 @SerializedName("score")
 private String score;

 @SerializedName("Words")
 private List<Words> mWords = new ArrayList<Words>();

 @SerializedName("seek")
 private String seek;

public String getCount() {
    return count;
}

public void setCount(String count) {
    this.count = count;
}

public String getColbreak() {
    return colbreak;
}

public void setColbreak(String colbreak) {
    this.colbreak = colbreak;
}

private String getName() {
    return name;
}

private void setName(String name) {
    this.name = name;
}

public String getScore() {
    return score;
}

public void setScore(String score) {
    this.score = score;
}

public List<Words> getmWords() {
    return mWords;
}

public void setmWords(List<Words> mWords) {
    this.mWords = mWords;
}

public String getSeek() {
    return seek;
}

public void setSeek(String seek) {
    this.seek = seek;
}
}

Words.class 

public class Words {
@SerializedName(value ="count")
private String count;
@SerializedName(value="Word")
private String Word;
@SerializedName(value="score")
private String name;
@SerializedName(value="Words")
private String words;
@SerializedName(value="seek")
private String seek;

    public String getCount() {
    return count;
}
public void setCount(String count) {
    this.count = count;
}
public String getWord() {
    return Word;
}
public void setWord(String Word) {
    this.Word = Word;
}
public String getName() {
    return name;
}
public void setName(String name) {
    this.name = name;
}
public String getWords() {
    return words;
}
public void setWords(String words) {
    this.words = words;
}
public String getSeek() {
    return seek;
}
public void setSeek(String seek) {
    this.seek = seek;
}
}

il manque un paramètre dans words.class, vous pouvez l'ajouter.

GSON ne prend pas directement en charge les caractères UTF-8. Ainsi, lors de la réception de la réponse via http, vous devrez la convertir en forme utf-8 dans la réponse de http elle-même.

vous pouvez essayer d'utiliser:

String jsonString = new Gson().toJson(objectToEncode);
byte[] utf8JsonString = jsonString.getBytes("UTF8");
responseToClient.write(utf8JsonString, 0, utf8JsonString.Length);

Bonjour utiliser ci-dessous gradle lib

compile 'com.google.code.gson:gson:2.2.4'

Classe Json 

import Java.util.List;
public class GsonParse{

/**
 * count : 12
 * colbreak : 1
 * name : unary rels
 * score : 9090
 * Words : [{"count":6,"Word":"prp_għaċ-","name":"prp_għaċ-","score":9.1,"Words":"kol","seek":2231297}]
 * seek : 0
 */

private String count;
private int colbreak;
private String name;
private String score;
private int seek;
/**
 * count : 6
 * Word : prp_għaċ-
 * name : prp_għaċ-
 * score : 9.1
 * Words : kol
 * seek : 2231297
 */

private List<WordsBean> Words;

public String getCount() {
    return count;
}

public void setCount(String count) {
    this.count = count;
}

public int getColbreak() {
    return colbreak;
}

public void setColbreak(int colbreak) {
    this.colbreak = colbreak;
}

public String getName() {
    return name;
}

public void setName(String name) {
    this.name = name;
}

public String getScore() {
    return score;
}

public void setScore(String score) {
    this.score = score;
}

public int getSeek() {
    return seek;
}

public void setSeek(int seek) {
    this.seek = seek;
}

public List<WordsBean> getWords() {
    return Words;
}

public void setWords(List<WordsBean> Words) {
    this.Words = Words;
}

public static class WordsBean {
    private int count;
    private String Word;
    private String name;
    private double score;
    private String Words;
    private int seek;

    public int getCount() {
        return count;
    }

    public void setCount(int count) {
        this.count = count;
    }

    public String getWord() {
        return Word;
    }

    public void setWord(String Word) {
        this.Word = Word;
    }

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public double getScore() {
        return score;
    }

    public void setScore(double score) {
        this.score = score;
    }

    public String getWords() {
        return Words;
    }

    public void setWords(String Words) {
        this.Words = Words;
    }

    public int getSeek() {
        return seek;
    }

    public void setSeek(int seek) {
        this.seek = seek;
    }
}

}

L'API appelant a mis sa réponse dans le code ci-dessous et dans Retrive Data 

GsonParse gsonparse = gson.fromJson(response, GsonParse.class);
//gsonparse.getWords() // It will returns list of Words
//Also do loop and get more data using data
gsonparse.getColbreak();
gsonparse.getSeek();
for (GsonParse.WordsBean data:gsonparse.getWords())
{

    data.getName();

}

espérons que cela vous aidera ..

Remplacer 

@SerializedName("name") public String count; avec 

@SerializedName("name")
public String name;

Je suppose que le problème est que vous utilisez public String count; à la fois pour @SerializedName("count") et @SerializedName("name")

Merci.

Essaye ça:

JSONArray jsonarray = jsonObject.getJSONArray("responseData");
Type listType = new TypeToken<ArrayList<AllUsers>>(){}.getType();
List<AllUsers> allUserses = 
    new GsonBuilder().create().fromJson(jsonarray.toString(), listType);

for(AllUsers user: allUserses){
         allUsersDao.insertOrReplace(user);
}

Il manque beaucoup de choses dans votre code.

S'il vous plaît regardez ci-dessous le code et essayez ce code ..
