I have created a class RoundIcon which extends View and the class contains setIconImage() method:

```
public void setIconImage(int imageFromResources) {
    iconImage = BitmapFactory.decodeResource(getResources(), imageFromResources);
    iconWidth = iconImage.getWidth();
    iconHeight = iconImage.getHeight();
    refreshDrawableState();
}

```

and there is a method onDraw():

```
@Override
protected void onDraw(Canvas canvas) {

    if(px == 0 || py == 0)
    {
        px = 50;
        py = 50;
    }

    canvas.drawCircle(px, py, circleRadius, circlePaint);
    canvas.save();

    if(iconImage != null)
    {
        int cardinalX = px - iconWidth/2;
        int cardinalY = py - iconHeight/2;
        canvas.drawBitmap(iconImage, cardinalX, cardinalY, iconPaint);
    }

    canvas.restore();
}

```

The problem is that the function onDraw() doesn't execute each time the method setIconImage() is called from main activity and therefore the icon doesn't change in the user interface.

Does anyone know how to modify the code in order to redraw an image every time the method setIconImage is called?
