Answer 1

In my case, I use the SherlockFragment and had the same problem.

After replacing the LinearLayout to ViewGroup, it shows the graph.

ViewGroup chartContainer = (ViewGroup)view.findViewById(R.id.chart_container);

I hope it works for you and others who have the same problem.

Answer 2

getView doesn't work until AFTER onCreateView completes: http://developer.android.com/reference/android/app/Fragment.html#getView()

Use the View that you inflate in onCreateView as a starting point to "find" your other views while you're still in onCreateView, instead of getView().

For example:

View view = (LinearLayout) inflater.inflate(R.layout.tab_frag1_layout,
                container, false);
LinearLayout chartContainer = (LinearLayout) view.findViewById(
        R.id.chart_container);
...
return view;

(Assuming "tab_frag1_layout" has the "chart_container" layout inside it.)
