Hi everyone, I'm currently developing an application with custom drawables and i'm kind of lost. I do not use XML since all kind of the parameters have to be computed on the fly. I have a main custom view holding all the gui. I made a class mcDrawable extending drawable implementing Drawable.Callback. In its draw method, i draw a couple of primitive (circles, and so on) An instance of mcDrawable is displayed via the onDraw method of the view.
When I trigger a motionEvent in the view, it calls a certain method in an instance of mcDrawable which modifies the shapes. Since I call an invalidate() after each event in the view, the drawable is updated nicely during the motion. So far, all is good. When I stop the motion (ACTION_UP), it triggers another method in the instance of mcDrawable which send a message to an Handler in mcDrawable which animate it by the mean of delayed messages. However, the View is not aware of these changes and therefore, does not redraw the drawable. To achieve the proper behavior, i made the view static, with a Handler, and send a message from mcDrawable Handler to the one of the view. When the view receive it, it invalidates. However, I don't think that its the proper way to achieve this ! So my question is the following: is there a proper way for mcDrawable to ask the View to redraw it, by the mean of Drawable.Callbacks for example ? I understand that it may use a selfInvalidate() in mcDrawable, but I don't understand how to link it to the view. Could someone help me ?
