是否可以加载在android中的InfoWindow中重绘的画布？

Question

我有一个探测器。我想在Infowindow画一个温度计，温度从json加载。这种温度计必须以最大和最小的温度加载。如果我在一个单独的proyect中做它可以正常工作，但是当我尝试加载infowindow时画布不起作用。我留下一些图片。

分开的项目。 1

在infoWindow proyect中 2

我加载customMarkerAdapter。

gMap.setInfoWindowAdapter(new CustomMarkerAdapter(getContext(),city,maxT,minT,weatherObject));

CustomMarkerAdapter的代码

public class CustomMarkerAdapter implements GoogleMap.InfoWindowAdapter {

    private double tempMax,tempMin;
    private Context context;
    private Geoname city;
    private WeatherObject weatherObject;

    public CustomMarkerAdapter(Context contextC, Geoname geocity, double maxT, double minT, WeatherObject weatherObjectP) {
        tempMax=maxT;
        tempMin=minT;
        context=contextC;
        city=geocity;
        weatherObject=weatherObjectP;
    }

    @Override
    public View getInfoWindow(Marker marker) {
        return null;
    }

    @Override
    public View getInfoContents(Marker marker) {
        LayoutInflater inflater= (LayoutInflater)context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
        final View rowView=inflater.inflate(R.layout.custom_marker,null,true);

        RelativeLayout rlTer= (RelativeLayout) rowView.findViewById(R.id.rlTer);

        //here i load my customMarker
        rlTer.addView(new com.example.lenovo_talentomobile.jsongson.CustomView.CustomMarker(context,tempMax,tempMin));

        TextView tvCiudad= (TextView) rowView.findViewById(R.id.tvPrueba);
        TextView tvHumedad= (TextView) rowView.findViewById(R.id.tvValueH);

        tvCiudad.setText(city.asciiName);
        tvHumedad.setText(String.valueOf(weatherObject.weatherObservations.get(0).humidity)+"%");

        return  rowView;
    }

}

customMarker的代码

public class CustomMarker extends View {

private double tempMax,tempMin;
private Paint paintNegro,paintBlanco,paintAzul,paintRojo;
private int barMax=0,barMin=0;
private int increasingM,increasingMin;

    super(context);
    tempMax=tempMaxC;
    tempMin=tempMinC;
    init();
}

public CustomMarker(Context context, AttributeSet attrs) {
    super(context, attrs);
    init();

public CustomMarker(Context context, AttributeSet attrs, int defStyleAttr) {
    super(context, attrs, defStyleAttr);

@Override

    pintaFigura(canvas);

    barMax=barMax+increasingM;
    moverYMax(barMax,tempMax);

    if(barMin<tempMin) {
        barMin = barMin + increasingMin;
        moverYMin(barMin, tempMin);
    }

    canvas.drawLine(18,90,18,90-(70*barMax/60),paintRojo);
    canvas.drawLine(31,90,31,90-(70*barMin/60),paintAzul);

    if(y<max){
        increasingM=1;

    }
}


public void moverYMin(float y, double max){
    if(y<max){

        invalidate();
    }
}
