How to inflate two different menus for a Toolbar and a BottomAppBar

The following causes a post-install crash in emulator. No debug info shown.

getMenuInflater().inflate(R.menu.top_bar, menu);
return true;
}
#Override

super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Toolbar top_toolbar = findViewById(R.id.top_toolbar);
setSupportActionBar(top_toolbar);
getSupportActionBar().setDisplayShowTitleEnabled(false);
BottomAppBar bottom_toolbar = findViewById(R.id.bottom_toolbar);
bottom_toolbar.replaceMenu(R.menu.bottom_bar);
SectionsPagerAdapter sectionsPagerAdapter = new SectionsPagerAdapter(this, getSupportFragmentManager());
ViewPager viewPager = findViewById(R.id.view_pager);
viewPager.setAdapter(sectionsPagerAdapter);
TabLayout tabs = findViewById(R.id.tabs);
tabs.setupWithViewPager(viewPager);
ImageButton my_posts_button = findViewById(R.id.my_posts_button);
ImageButton chats_button = findViewById(R.id.chats_button);
ImageButton post_button = findViewById(R.id.post_button);
ImageButton settings_button = findViewById(R.id.settings_button);
ImageButton profile_button = findViewById(R.id.profile_button);
ImageButton sort_button = findViewById(R.id.search_button);
ImageButton search_button = findViewById(R.id.sort_button);
}
}

You are using both a Toolbar and a BottomBar. You can use the onCreateOptionsMenu only for the bar used in the setSupportActionBar.
For example:
Toolbar toolbar = findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
and onCreateOptionsMenu for the Toolbar menu:
#Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.toolbar_menu, menu);
return true;
}
Then for the BottomBar you can use the app:menu in the layout or the replaceMenu method:
BottomAppBar bottomAppBar = findViewById(R.id.bottomappbar);
bottomAppBar.replaceMenu(R.menu.bottom_bar);
bottomAppBar.setOnMenuItemClickListener(new Toolbar.OnMenuItemClickListener() {
#Override
public boolean onMenuItemClick(MenuItem item) {
if (item == R.id...){
//....
return true;
}
return false;
}
});

Menu in a custom toolbar not showing in a fragment

So I have had asked this multiple times but I can't get a decent answer to my question.
Can someone please tell me why my menu is not showing in my custom toolbar?
PurchaseItemList.java

import android.view.MenuItem;
import android.view.View;
import android.view.ViewGroup;
import android.widget.AdapterView;
import android.widget.ArrayAdapter;
import android.widget.SearchView;
import android.widget.Spinner;
import android.widget.Toast;
import com.example.devcash.R;
/**

public class PurchaseItemListFragment extends Fragment implements SearchView.OnQueryTextListener, MenuItem.OnActionExpandListener {

Spinner itemListSpinner;
public PurchaseItemListFragment() {
// Required empty public constructor
}
#Override
public void onCreate(#Nullable Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
//inflate the menu
setHasOptionsMenu(true);
}
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
// Inflate the layout for this fragment
View view = inflater.inflate(R.layout.fragment_purchase_item_list, container, false);
itemListToolbar = (Toolbar) view.findViewById(R.id.toolbar_purchaseitemlist);
itemListSpinner = (Spinner) view.findViewById(R.id.spinner_allcategories);
///
ArrayAdapter<String> myAdapter = new ArrayAdapter<String>(getActivity(),
R.layout.custom_spinner_item,
getResources().getStringArray(R.array.dropdownitempurchase));
myAdapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
itemListSpinner.setAdapter(myAdapter);
itemListSpinner.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
#Override
public void onItemSelected(AdapterView<?> parent, View view, int position, long id) {
Toast.makeText(getActivity(),
itemListSpinner.getSelectedItem().toString(),
Toast.LENGTH_SHORT).show();
}
#Override
public void onNothingSelected(AdapterView<?> parent) {
}
});
return view;
}
//handles the search menu
#Override
public void onCreateOptionsMenu(Menu menu, MenuInflater inflater) {
inflater.inflate(R.menu.searchmenu, menu);
MenuItem searchItem = menu.findItem(R.id.action_search);
SearchView searchView = (SearchView) searchItem.getActionView();
searchView.setOnQueryTextListener(this);
searchView.setQueryHint("Search..");
super.onCreateOptionsMenu(menu, inflater);
}
#Override
public boolean onQueryTextSubmit(String query) {
return false;
}
#Override
public boolean onQueryTextChange(String newText) {
return false;
}
#Override
public boolean onMenuItemActionExpand(MenuItem item) {
return true;
}
#Override
public boolean onMenuItemActionCollapse(MenuItem item) {
return true;
}
}
and this is a snippet of my custom toolbar in my fragment_purchase_item_list.xml
<android.support.v7.widget.Toolbar
android:id="#+id/toolbar_purchaseitemlist"
android:layout_width="match_parent"
android:layout_height="wrap_content"
app:theme="#style/ThemeOverlay.AppCompat.Dark.ActionBar"
style="#style/PrimaryHeaderBar"
android:elevation="4dp">
<Spinner
android:id="#+id/spinner_allcategories"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:popupTheme="#style/ThemeOverlay.AppCompat.Light"/>
</android.support.v7.widget.Toolbar>
I have tried checking all the related posts from the internet and can't find a decent tutorial on YT. Can someone tell me what is going on here?

Add following line in onCreateView() method
setHasOptionsMenu(true)
Also add below line in onViewCreated() method
(activity as AppCompatActivity?)!!.setSupportActionBar(customToolbar as Toolbar?)
Where customToolBar is the id of the toolbar added in xml file

Add this in your onCreateView method
setHasOptionsMenu(true);

Search Bar for a seperate fragment

I have made different fragments inside one Activity (Home.java) on which toolbar and navigation drawer is there.
Right now I thought to put searchview inside fragment.We usually write all code related to searchview inside oncreateoption menu. I have done the same thing but oncreateoption is made inside fragment.
I'm not getting any error but searchbar is not be shown over the toolbar.
package com.example.foody;
import android.database.Cursor;
import android.os.Bundle;
import android.support.v4.app.Fragment;
import android.support.v7.widget.LinearLayoutManager;
import android.support.v7.widget.RecyclerView;
import android.support.v7.widget.SearchView;
import android.view.LayoutInflater;
import android.view.Menu;
import android.view.MenuInflater;
import android.view.MenuItem;
import android.view.View;
import android.view.ViewGroup;
import java.util.ArrayList;
public class fitem extends Fragment implements SearchView.OnQueryTextListener
{
RecyclerView rv1;
fitemAdapter adapter;
ArrayList<All_Data> item;
Cursor cr;
Storage sob;
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState)
{
View v=inflater.inflate(R.layout.fragment_fitem, container, false);
sob=new Storage(getContext());
Bundle bundle = this.getArguments();
if (bundle == null)
cr=sob.allData(); //if called from home page
else
cr=sob.categorisedData(bundle.getString("category")); // if called from category page
inData();
rv1=v.findViewById(R.id.rv1);
rv1.setHasFixedSize(true);
rv1.setLayoutManager(new LinearLayoutManager(getContext()));
adapter=new fitemAdapter(getContext(),item);
rv1.setAdapter(adapter);
return v;
}
void inData()
{
item=new ArrayList<>();
while(cr.moveToNext())
{
item.add(new All_Data(cr.getString(0),cr.getString(2),cr.getString(3)));
}
}
public void onCreateOptionsMenu(Menu menu, MenuInflater inflater)
{
super.onCreateOptionsMenu(menu, inflater);
inflater.inflate(R.menu.tool_menu, menu);
MenuItem searchItem = menu.findItem(R.id.search1);
SearchView searchView = (SearchView) searchItem.getActionView();
searchView.setOnQueryTextListener(fitem.this);
searchView.setQueryHint("Search");
}
#Override
public boolean onQueryTextChange(String s)
{
String userInput=s.toLowerCase();
ArrayList<All_Data> filterlist=new ArrayList<>();
for(int i=0;i<item.size();i++)
{
String st=item.get(i).getName().toLowerCase();
if(st.contains(userInput))
filterlist.add(item.get(i));
}
adapter=new fitemAdapter(getContext(),filterlist);
rv1.setAdapter(adapter);
return true;
}
#Override
public boolean onQueryTextSubmit(String s) {
return false;
}
}

Inside your fragment's onCreate()/onCreateView() call setHasOptionsMenu(true);
This will allow your fragment to show the menu items you inflate inside the fragment's onCreateOptionsMenu(); otherwise it uses the host Activity's menu.

getSupportMenuInflater() is undefined for the type MainActivity with SlidingMenu + ABS

I am using Sliding Menu + ActionBarSherlock and for some "strange" reason I am getting this error. I get similar errors for "onCreateOptionsMenu" and "onOptionsItemSelected". I thought that importing Menu, MenuInflater and MenuItem from ABS would have solved the issues, but still I can't find the solution.
There shouldn't be any problem related to the dependencies between my project, ABS and SlidingMenu. Further I have extended all the classes correctly. Do you guys have any advice? Thanks.
import android.os.Bundle;
import android.support.v4.app.Fragment;
import android.support.v4.app.FragmentManager;
import com.actionbarsherlock.view.Menu;
import com.actionbarsherlock.view.MenuInflater;
import com.actionbarsherlock.view.MenuItem;
import com.jeremyfeinstein.slidingmenu.lib.SlidingMenu;
import com.jeremyfeinstein.slidingmenu.lib.app.SlidingFragmentActivity;
public class MainActivity extends SlidingFragmentActivity {
private Fragment mMapFragment;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
setBehindContentView(R.layout.menu_frame);
getSlidingMenu().setMode(SlidingMenu.LEFT_RIGHT);
getSlidingMenu().setTouchModeAbove(SlidingMenu.TOUCHMODE_NONE);
FragmentManager fm = getSupportFragmentManager();
mMapFragment = fm.findFragmentById(R.id.container);
if (savedInstanceState == null) {
mMapFragment = new RunMapFragment();
fm.beginTransaction()
.add(R.id.container, mMapFragment)
.commit();
}
getSlidingMenu().setSecondaryMenu(R.layout.menu_frame_two);
getSlidingMenu().setBehindOffsetRes(R.dimen.slidingmenu_offset);
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu items for use in the action bar
MenuInflater inflater = getSupportMenuInflater();
inflater.inflate(R.menu.main_activity_actions, menu);
return super.onCreateOptionsMenu(menu);
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
// Handle presses on the action bar items
switch (item.getItemId()) {
case R.id.button1:
getSlidingMenu().showMenu();
return true;
case R.id.button2:
getSlidingMenu().showSecondaryMenu();;
return true;
default:
return super.onOptionsItemSelected(item);
}
}
}

SlidingMenuActivity appears to inherit from FragmentActivity, not SherlockFragmentActivity, and so you do not have ActionBarSherlock support, such as getSupportMenuInflater().
You may have to clone SlidingMenuActivity and create SherlockSlidingMenuActivity, changing it to inherit from SherlockFragmentActivity, then use your SherlockSlidingMenuActivity as the base class for your MainActivity.

#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);

// TODO Auto-generated method stub
}
}

thanks in advance

Just use a
Intent intent = new Intent(this, YourActivityToStart.class);
startActivity(intent);
on the position where you pop up a Toast.

Using 'app' instead of 'android' namespace prefix for 'actionLayout' attribute fixed it for me.
So, basically, use
app:actionLayout="#layout/yourLayout"
instead of
android:actionLayout="#layout/yourLayout"
I am assuming you are using app_compat library to get the theming engine.
