 ***//Fragment Not open here show error////
***

                Fragment fragment= new XYZ();
                FragmentTransaction transaction = getFragmentManager().beginTransaction();
                transaction.replace(R.id.fragment_container, fragment); 
                transaction.addToBackStack(null);  // this will manage backstack
                transaction.commit();


                }
                if(MyName.getText().toString()=="ABC")
                {



*** //Here Its Work When I open activity inside it*** 

                    Intent intent=new Intent(v.getContext(),ExtraActivityFormTesting.class);
                    context.startActivity(intent);
