The overflow menu icon is not showing in my Activity with a tab style navigation layout. The tabs are implemented using a ViewPager, Fragments and a TabLayout.
The overflow menu is showing in my Activities which do not have tabs which makes me think the overflow menu not showing is something to do with my implementation of the tabs navigation.
Here is a basic model of my Activity:
public class MainActivity extends AppCompatActivity {
TabLayout tabLayout;
ViewPager viewPager;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main_layout);
initTabLayout();
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.menu_layout, menu);
return super.onCreateOptionsMenu(menu);
}
@Override
public boolean onPrepareOptionsMenu(Menu menu) {
return super.onPrepareOptionsMenu(menu);
}
public void initTabLayout(){
tabLayout = (TabLayout) findViewById(R.id.tabLayout);
tabLayout.setTabTextColors(Color.parseColor("#e3e8e7"), Color.parseColor("#7e7e7e"));
viewPager = (ViewPager) findViewById(R.id.viewPager);
viewPager.setOffscreenPageLimit(4); //this stops the tabs from losing their data when you change tabs
//sets up adapter that contains the scrolling pageAdapter and the fragment which is displayed
viewPager.setAdapter(new ActivityTabAdapter(getSupportFragmentManager(),
MainActivity.this));
tabLayout.setupWithViewPager(viewPager);
viewPager.addOnPageChangeListener(new ViewPager.OnPageChangeListener() {
@Override
public void onPageScrolled(int position, float positionOffset, int positionOffsetPixels) {
}
@Override
public void onPageSelected(int position) {
}
@Override
public void onPageScrollStateChanged(int state) {
}
});
}
}
And here is my FragmentPagerAdapter implementation:
public class ActivityTabAdapter extends FragmentPagerAdapter {
@Override
public Parcelable saveState() {
return super.saveState();
}
final int PAGE_COUNT = 4;
private String tabTitles[] = new String[]{"tab1", "tab2", "tab3", "tab4"};
private Context context;
public ActivityTabAdapter(FragmentManager fm, Context context) {
super(fm);
this.context = context;
}
@Override
public int getCount() {
return PAGE_COUNT;
}
@Override
public Fragment getItem(int position) {
return PageFragment.newInstance(position + 1);
}
@Override
public CharSequence getPageTitle(int position) {
// Generate title based on item position
return tabTitles[position];
}
//These are fragments which hold the layouts of the tabs
public static class PageFragment extends Fragment {
public static final String ARG_PAGE = "ARG_PAGE";
Context mContext;
View tab1rootView;
View tab2Rootview;
View tab3RootView;
View tab4RootView;
Tab1 tab1;
Tab2 tab2;
Tab3 tab3;
Tab4 tab4;
private int mPage;
public static PageFragment newInstance(int page) {
Bundle args = new Bundle();
args.putInt(ARG_PAGE, page);
PageFragment fragment = new PageFragment();
fragment.setArguments(args);
return fragment;
}
MenuInflater mInflater;
@Override
public void onCreateOptionsMenu(Menu menu, MenuInflater inflater) {
super.onCreateOptionsMenu(menu, inflater);
mInflater = inflater;
inflater.inflate(R.menu.menu_layout, menu);
}
@Override
public void onPrepareOptionsMenu(Menu menu) {
super.onPrepareOptionsMenu(menu);
mInflater.inflate(R.menu.menu_layout, menu);
}
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setHasOptionsMenu(true);
mContext = getActivity();
mPage = getArguments().getInt(ARG_PAGE);
Log.v("whichFrag", "" + getArguments().getInt(ARG_PAGE));
}
@Override
public void onActivityCreated(Bundle savedInstanceState) {
super.onActivityCreated(savedInstanceState);
setHasOptionsMenu(true);
}
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
setHasOptionsMenu(true);
tab1rootView = inflater.inflate(R.layout.tab1_layout, container, false);
tab2Rootview = inflater.inflate(R.layout.tab2_layout, container, false);
tab3RootView = inflater.inflate(R.layout.tab3_layout, container, false);
tab4RootView = inflater.inflate(R.layout.tab4_layout, container, false);
int i = getArguments().getInt(ARG_PAGE);
if (getArguments().getInt(ARG_PAGE) == 1) { //if 1, then we inflate tab1rootView layout
tab1 = new Tab1(tab1rootView, getActivity());
tab1.initCardViews1();
return tab1rootView;
} else if (getArguments().getInt(ARG_PAGE) == 2) { //if 2, then we inflate tab2Rootview layout
tab2 = new Tab2(tab2Rootview, mContext);
return tab2Rootview;
} else if (getArguments().getInt(ARG_PAGE) == 3) { //if 3, then we inflate tab3RootView layout
tab3 = new Tab3(tab3RootView, mContext);
return tab3RootView;
} else { //if 4, then we inflate tab4RootView layout
tab4 = new Tab4(tab4RootView, mContext);
return tab4RootView;
}
}
}
}
Here is my xml menu:
<menu xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
tools:context="com.example.heavymagikhq.profilepageofficial.profileEditorJava.Profile_info_editor">
<item android:id="@+id/action_settings" android:title="@string/action_settings"
android:orderInCategory="100" app:showAsAction="never" />
<item
android:id="@+id/action_settings2"
android:orderInCategory="100"
android:title="@string/action_settings"
app:showAsAction="never"
android:visible="true" />
<item
android:id="@+id/action_settings1"
android:orderInCategory="100"
android:title="@string/action_settings"
android:icon="@drawable/ic_action_menu"
app:showAsAction="never"
android:visible="true" />
</menu>
I have looked at other answers on stackoverflow but I couldn't find the answer.
I'll post more information if you need it.
Thanks in advance.
