Watsonのパーソナリティの洞察のデモでのJSON出力を得られません

Question

java sdkを使用して簡単なパーソナリティの洞察アンドロイドアプリケーションを構築するため、デモのように必要なJSON出力を取得できませんでした。

public class Analysis extends AppCompatActivity { 

private String textAnalysis; 
PersonalityInsights service; 

@Override 
protected void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.activity_analysis); 

    Intent intent = getIntent(); 
    textAnalysis = intent.getStringExtra("data"); 
    Log.i("DATA",textAnalysis+" ff"); 
    service = new PersonalityInsights(); 
      service.setUsernameAndPassword(getString(R.string.user_id),getString(R.string.password)); 


} 

@Override 
protected void onStart() { 
    super.onStart(); 
    new Thread(new Runnable() { 
     @Override 
     public void run() { 
      Profile profile = service.getProfile(textAnalysis+"").execute(); 
      Log.i("Analysis",profile.toString()); 
      Trait trait = profile.getTree(); 
      Log.i("Analysis","Categories"+trait.getCategory()); 
      Log.i("Analysis","Name"+trait.getName()); 
      Log.i("Analysis","Children"+trait.getChildren().get(1).getName()); 
      Log.i("Analysis","Percentage"+trait.getPercentage()); 
     } 
    }).start(); 

} 
    }                    

ただし、出力はデモとは異なります。これは、値や他のもの

Answer 1

APIは、常に3つのモデル、Big5の、ニーズや価値観とのプロファイルを返し、必要、ビッグ5性格特性を持っていませんでした。

ProfileオブジェクトでtoString()メソッドを呼び出すと、JSONレスポンス全体が出力されるはずです。

ここでの問題は、あなたがJSON出力を理解していないことだと思います。 API Referenceを見て、そこにJSON出力が記述されています。

API Explorerを使用してAPIをテストし、実際の結果を得ることもできます。
