Creating a custom LinearLayout from within a custom LinearLayout

Question

I'm designing my own tab control. I've created 2 custom views. The first is called MyTab and derives from LinearLayout. The second is called MyTabBar and derives from LinearLayout.

The constructor of both look something like this:

public MyTab(Context context, AttributeSet attrs) {
    super(context, attrs);

    LayoutInflater inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
    inflater.inflate(R.layout.layout_my_tab, this);
}

MyTabBar has a member variable which is an ArrayList of MyTabs. I have a public function called addTab(String strTabName) to add a new MyTab to the MyTabBar. My question is, when I do the following:

MyTab tab = new MyTab(...);

inside of MyTabBar, how do I obtain the Context and AttributeSet required to be passed to MyTab?

Or should I be inflating it somehow?

you shouldn't inflate in a view's constructor, i don't think this is what you want to do — Tourki

the inflater.inflate method returns a view that you are not using, you are not storing it and you can't return it in a constructor, you are confusing inflation and construction — Tourki

The view's constructor with a AttributeSet parameter is used only when you inflate the view from an xml file, otherwise write a constructor having only a Context parameter, and use super(context); to get the context from MyTabBar, use this.getContext();
