I isolated my error and it seems to come from that line:

mJours.add(new Jour((String.valueOf(cn.get_id()) + " Mars 2016"), cn.get_minimum(), cn.get_maximum()));

The code of my java class Jour is :

 public class Jour {    
    private int mTempMin;
    private int mTempMax;
    private String mDates;

    public Jour(String date, int min, int max) {
        mTempMin = min;
        mTempMax = max;
        mDates = date;
    }    

    public String getmDates() {
        return mDates;
    }

    public void setmDates(String mDates) {
        this.mDates = mDates;
    }

    public int getmTempMin() {
        return mTempMin;
    }

    public void setmTempMin(int mTempMin) {
        this.mTempMin = mTempMin;
    }

    public int getmTempMax() {
        return mTempMax;
    }

    public void setmTempMax(int mTempMax) {
        this.mTempMax = mTempMax;
    }    
}

Thank you, I hope we can find an answer!

JourAdapteur class:

public class JourAdapteur extends ArrayAdapter {

private Context mContext;
private LayoutInflater mInflater;

public JourAdapteur(Context context, ArrayList<Jour> jours) {
    super(context, 0, jours);
    mContext = context;
    mInflater = LayoutInflater.from(context);
}

@Override
public View getView(int position, View convertView, ViewGroup parent) {
    View theView = convertView;

    if (theView == null) {
        theView = mInflater.inflate(R.layout.jour_list_item, parent, false);
    }

    // Le hero
    Jour jour = this.getItem(position);

    // Aller chercher les objets
    TextView lblMin = (TextView) theView.findViewById(R.id.lblMin);
    TextView lblMax = (TextView) theView.findViewById(R.id.lblMax);
    TextView lblDate = (TextView) theView.findViewById(R.id.lblDate);

    // Assigner les valeurs
    lblMin.setText(jour.getmTempMin());
    lblMax.setText(jour.getmTempMax());
    lblDate.setText(jour.getmDates());


    // Retourner la vue
    return theView;
}

@Override
public View getDropDownView(int position, View convertView, ViewGroup parent) {
    // TODO Auto-generated method stub
    return getView(position, convertView, parent);
}

}

lblMin.setText(jour.getmTempMin());
lblMax.setText(jour.getmTempMax());

You're calling setText(int) that expects a resource id. To use setText(CharSequence) instead, you can change the code to e.g.

lblMin.setText(String.valueOf(jour.getmTempMin()));
lblMax.setText(String.valueOf(jour.getmTempMax()));
