.java not using the 2- or 3-argument View constructors; XML attributes will not work

Question

i\'m newbie i have problem creating game

activity_main.xml -> MainActivity.java -> GameLoop.java -> action.xml (error) -> CustomView.java

Answer 1

I think it depends how You creating Your custom view and how You gonna use it .
Not all 3 constructors really necessary.
If You create the view with attributes xml file, but won't use defstyle, its enough to call

public CustomView(Context context, AttributeSet attrs) {
    this(context, attrs);
    //Your code
}

if You not using attributes and defstlye /i saw examples for this/ You happy to call only

public CustomView(Context context) {
    super(context);
    //Your code
}

and if You want use defstyle and attributes too

public CustomView(Context context, AttributeSet attrs) {
    this(context, attrs);
    //Yourcode
}
