You can use use findFragmentById in FragmentManager   Since you are using the Support library  you are extending FragmentActivity  you can use   getSupportFragmentManager   findFragmentById R id pageview    If you are not using the support library  so you are on Honeycomb  and you don t want to use the support library    getFragmentManager   findFragmentById R id pageview    Please consider that using the support library is recommended even on Honeycomb
