Android: how to set context for presentation in xml layout?

Question

I am using a WebView in an ActivityGroup, and it will throw an exception if the WebView displays Dialog and reports that the action is invalid. But this is normal if I set the WebView context to TOP activity. So, I want to know how to set context in xml layout?

Answer 1

To achieve this, you can use layoutinflater:

View viewToLoad = LayoutInflater.from(this.getParent()).inflate(R.layout.yourLayoutName, null);
this.theSpinner = (Spinner) viewToLoad.findViewById(R.id.Spinny);
this.setContentView(viewToLoad );

Hope this helps. for dialogue you can just change the context from this to

this.getParent()
