MPAndroidChart 삽입 Y 축 listArray 변수 또는 다이나믹 매개 변수

Question

Y 축 (MPAndroidChart)에 변수 또는 동적 매개 변수를 소개하고 싶습니다. 매개 변수는 원격 서버에서 제공되며 센서에서 실시간으로 catch되는 "온도 및 습도"이므로 매개 변수를 수정하지 않은 다음 매개 변수를 Mysql에 할당하고 APP에서이 데이터를 가져온 후에 차트를 만듭니다.

나는 그것을 만드는 방법에 대한 도움을 받고 싶습니다. 방법 loopj을 사용 CapatarParametros()에 PARAMS (습도와 온도)에 대한

은 서버와 데이터를 가져 오는에 연결 :

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); 

이 코드는 나에게 온도와 humedity을 줄이 같은 내 코드가 있습니다. 지금은 한 OnCreate에서 ("온도"exemple 당)이 매개 변수를 사용하고 y 축에 추가해야합니다

두 가지 활동을 만듭니다. 하나는 차트 용이고 다른 하나는 Asyncronics 용 인터페이스입니다. 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)); 
     //entries.add(new Entry(6f, 1)); 
     //entries.add(new Entry(6f, 2)); 
     //entries.add(new Entry(2f, 3)); 
     //entries.add(new Entry(18f, 4)); 
     //entries.add(new Entry(60f, 5)); 

     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); 

} 

난 그냥 단순화하기 위해, 그것은 관련이없는 몇 가지 코드를했다.
