here tabspageradapter class well:

package info.androidhive.tabsswipe.adapter; import android.support.v4.app.fragment; import android.support.v4.app.fragmentmanager; import android.support.v4.app.fragmentpageradapter; import com.spicycurryman.getdisciplined10.app.customlist_activity; import com.spicycurryman.getdisciplined10.app.installedappactivity; import com.spicycurryman.getdisciplined10.app.pre_installedapp_activity; public class tabspageradapter extends fragmentpageradapter { public tabspageradapter(fragmentmanager fm) { super(fm); } @override public fragment getitem(int index) { switch (index) { case 0: homecoming new installedappactivity(); case 1: homecoming new pre_installedapp_activity(); case 2: homecoming new customlist_activity(); } homecoming null; } @override public int getcount() { // item count - equal number of tabs homecoming 3; } }

moreover when seek utilize autocorrect says refactoring cannot performed. , when seek alter return new fragment(); instead nil shows up.

problem in 1 of tabs have fragmentactivity , unable homecoming class in scrollable tab.

it expect homecoming fragment not fragment activity. fragmentpager not take activity, activity cant instantiated fragments allowed.

documentation fragmentpageradapter

implementation of pageradapter represents each page fragment persistently kept in fragment manager long user can homecoming page.

solution:

return class extends fragment not fragment activity
