I'm trying to create navigation drawer
in my app. In one of my navigation drawer item
, View
, I want it to has 2 tabs
with swipe view
feature. I get error Viewview is not abstract and does not override abstract method onTabReselected
.
MainActivity // for navigation drawer item
import android.support.v4.app.Fragment;
import android.support.v4.app.FragmentManager;
private void selectItem(int position) {
Fragment fragment = null;
switch (position) {
case 0:
fragment=new Information();
break;
case 1:
fragment=new Claims1();
Bundle bundle=new Bundle();
bundle.putLong("ab",WorkDetailsTable.ab);
fragment.setArguments(bundle);
break;
case 2:
fragment=new ViewView();
break;
default:
break;
}
if (fragment != null) {
FragmentManager fragmentManager = getFragmentManager();
fragmentManager.beginTransaction().replace(R.id.content_frame, fragment).commit();
mDrawerList.setItemChecked(position, true);
mDrawerList.setSelection(position);
setTitle(mNavigationDrawerItemTitles[position]);
mDrawerLayout.closeDrawer(mDrawerList);
} else {
Log.e("MainActivity", "Error in creating fragment");
}
}
}

Error
Error:(50, 47) error: incompatible types: android.app.ActionBar cannot be converted to android.support.v7.app.ActionBar
Well, the error message is clear. Your ViewView
class implements TabListener
but doesn't contain implementation of onTabReselected
. You have an implementation of onTabReselected
in the anonymous class instance implementing ViewPager.OnPageChangeListener()
, which you define in your onCreateView
method.
The question is do you need ViewView
to implement TabListener
. If you do, add the methods required by TabListener
directly to ViewView
. If not, remove the implements ActionBar.TabListener
clause.
