Question

I would like to do the same effect with linearlayout like when you call showDialog. It is easy to disable all components of linear layout, but how can I change the color?

Is it possible to throw some shadow on layout?

Thank you for answer.

Answer 1

Thanks to Asok advice I found this:

Set Alpha/Opacity of Layout

It is working correct for me.

The way how I setClickable to ALL child:

TraverseChildren(GetChildren(_llRest), false);

where

private void TraverseChildren(ArrayList<View> childrenList, boolean b) {
    for (View view : childrenList) {

        view.setClickable(b);
        view.setEnabled(b);

        if (view instanceof ViewGroup)
            TraverseChildren(GetChildren((ViewGroup)view), b);
    }   
}

private ArrayList<View> GetChildren(ViewGroup view) {
    ArrayList<View> children = new ArrayList<View>();
        for (int i = 0; i < view.getChildCount(); i++) 
            if (view.getChildAt(i) != null)
                children.add(view.getChildAt(i));
    return children;
}
