MPAndroidChart Y-Achsenliste einfügenArray Variable oder Dynamic Parameter

Question

Ich möchte Variable oder Dynamic Parameter in Y-Achse (MPAndroidChart) einzuführen. Die Parameter kommen von Remote-Server, und sie sind keine festen Parameter, da sie "Temperatur und Luftfeuchtigkeit" von einem Sensor in Echtzeit erfasst werden, dann ist es in Mysql zugeordnet und von meiner APP ein Diagramm nach dem Abrufen dieser Daten.

Ich hätte gerne Hilfe, wie man es macht. Ich habe meinen Code wie folgt aus:

Für params (Feuchte und Temperatur) in Verfahren CapatarParametros() loopj mit dem Server zu verbinden und die Daten zu erhalten:

List<String> allNames = new ArrayList<String>(); 
JSONArray cast = jsonobject.getJSONArray("result"); 
for (int i=0; i<cast.length(); i++) { 
    JSONObject parametrosdht11 = cast.getJSONObject(i); 
    String temperatura = parametrosdht11.getString("temperatura"); 
    String humedad = parametrosdht11.getString("humedad"); 
    allNames.add(temperatura); 
    allNames.add(humedad); 

Dieser Code gibt mir Temperatur und humedity. Jetzt muss ich diese Parameter zu übernehmen und auf der y-Achse (pro exemple "Temperatur") in onCreate hinzufügen:

LineChart lineChart = (LineChart) findViewById(R.id.chart); 
ArrayList<Entry> entries = new ArrayList<>();

zwei Aktivitäten erstellen. Eine für Chart, eine andere Schnittstelle für Asyncronics. DataSensor.java

public class DatosSensor extends AppCompatActivity implements onLoopjTaskFinished { 

    private onLoopjTaskFinished loopjListener; 

    private DrawerLayout drawerLayout; 

    ProgressDialog prgDialog; 
    TextView errorMsg; 
    private String temeperatura; 

    ArrayList<Entry> entries; 

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

     String idObjeto = (String) getIntent().getExtras().getSerializable("IdentidadEnviada"); 

     CaptarParametros(idObjeto); 

     LineChart lineChart = (LineChart) findViewById(R.id.chart); 

     entries = new ArrayList<>(); 
     //entries.add(new Entry(60f, 0));

     Log.i(UtilitiesGlobal.TAG, "onCreate: entries size = " + entries.size()); 

     LineDataSet dataset = new LineDataSet(entries, "# of Calls"); 

     ArrayList<String> labels = new ArrayList<String>(); 


     LineData data = new LineData(labels, dataset); 
     dataset.setColors(ColorTemplate.COLORFUL_COLORS); // 
     dataset.setDrawCubic(true); 
     dataset.setDrawFilled(true); 


     lineChart.setData(data); 
     lineChart.animateY(5000); 


     //Toast.makeText(getApplicationContext(), idObjeto, Toast.LENGTH_LONG).show(); 

     agregarToolbar(); 

    @Override 
    public void onLoopjFinishedSuccess(JSONObject jsonObject) { 
     List<String> allNames = new ArrayList<String>(); 
     JSONArray cast = null; 
     try { 
      cast = jsonObject.getJSONArray("result"); 
     } catch (JSONException e) { 
      e.printStackTrace(); 
     } 
     for (int i = 0; i < cast.length(); i++) { 
      JSONObject parametrosdht11 = null; 
      String temperatura = null; 
      String humedad = null; 
      try { 
       parametrosdht11 = cast.getJSONObject(i); 
       temperatura = parametrosdht11.getString("temperatura"); 
       humedad = parametrosdht11.getString("humedad"); 
       allNames.add(temperatura); 
       allNames.add(humedad); 

       float tempFloat = Float.parseFloat(temperatura); 
       entries.add(new Entry(tempFloat, i)); 

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

      //Log.i(UtilitiesGlobal.TAG, "onSuccess: loopj " + usuarioiJSONbject); 
      Log.i(UtilitiesGlobal.TAG, "onSuccess: loopj " + "temperatura: " + temperatura + " humedad: " + humedad); 
     } 
    } 

Interface (onLoopjTaskFinished) 

    public interface onLoopjTaskFinished { 
    void onLoopjFinishedSuccess(JSONObject jsonObject); 
    void onLoopjFinishedFailure(int statusCode); 

} 

Ich habe einige Code aus, dass es nicht relevant ist, nur zu vereinfachen.
