How to dynamically change the size of a fragment from a WebView on clicking a button inside a WebView?

Question

Android

We have a fragment inside which the WebView lives:

public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
        Context context=getActivity().getApplicationContext();
        myFrameLayout=new FrameLayout(context);
        viewer =new WebView(context);
        viewer.setLayoutParams(new FrameLayout.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.MATCH_PARENT));
        myFrameLayout.addView(viewer);
        return myFrameLayout;
    }

We populate the fragment in the activity, display it, catch the JS command that is triggered when you click on any object inside the WebView, which should expand, resize the fragment to full screen, the fragment in the markup has the wrap_content property. How to implement it dynamically? In general, is it reasonable to use a fragment, or is it better to draw your own view and populate the WebView in it?

The addJavascriptInterface() method is what you need. There you can implement any logic.
