Problem with displaying top app and contextual action bar in fragment

Initially, I tried to make the context menu appear after a long press on the RecyclerView element of the first fragment.
Then I decided to make it at least appear.
My application consists of three chunks. I am using material design components. The top menu is displayed on the activity layout, and for now it should only change to the contextual menu of the first fragment.
Now the contextual menu is displayed by clicking on the RecyclerView element of the first fragment, but it appears, and the top menu does not disappear.
I need to display Toolbar Material separately on each fragment and somehow replace it with contextual one? Explain, please.

Ok, I fixed this by adding this <item name="windowActionModeOverlay">true</item> to the style. But the question remains the same - am I doing the right thing by displaying the top menu in the activity, and displaying the contextual action bar in the fragment?

Why my toolbar doesn't hide when SearchView action appears?

This is my toolbar
I am trying to create a search toolbar with Search ActionView, but when I opening the search bar the title of my toolbar is not being hidden. I tried to add in the menu.xml showAsAction = "collapseActionView" but it remains the same.
Here is my code:
AndroidManifest.xml
<activity
android:name="com.apps.screens.ContactsActivity"
android:exported="true"
android:parentActivityName=".MainActivity"
android:screenOrientation="portrait"
android:theme="#style/AppTheme.NoActionBar" />
Activity.java
public class ContactsActivity extends AppCompatActivity {
private List<Contact> items;
private RecyclerView recyclerView;
private ContactPhoneAdapter adapter;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_contacts);
Toolbar toolbar = findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
getSupportActionBar().setDisplayHomeAsUpEnabled(false);
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.contacts_menu, menu);
MenuItem item = menu.findItem(R.id.search);
SearchView searchView = (SearchView) item.getActionView();
searchView.setOnQueryTextListener(new SearchView.OnQueryTextListener() {
#Override

I appreciate any suggestion

In this piece of code , add the following line of code
searchview.maxWidth = Integer.MAX_VALUE
#Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.contacts_menu, menu);
MenuItem item = menu.findItem(R.id.search);
SearchView searchView = (SearchView) item.getActionView();
searchview.maxWidth = Integer.MAX_VALUE // add this line of code
searchView.setOnQueryTextListener(new SearchView.OnQueryTextListener() {
#Override
public boolean onQueryTextSubmit(String query) {
return false;
}
#Override
public boolean onQueryTextChange(String newText) {
adapter.getFilter().filter(newText);
return false;
}
});
return true;
}
}

MenuItem menuItem = menu.findItem(R.id.action_search);
searchView = (SearchView)MenuItemCompat.getActionView(menuItem);
searchView.setOnQueryTextListener(this);
return super.onCreateOptionsMenu(menu);
}
And onOptionItemSelected method:
#Override

switch (item.getItemId()){
case R.id.refresh:
//Check the internet connection
if(Util.isConnected(this)){
// showProgress();
//Check if there is not pending item
sincronize(this);
dbManager.borrar();
new HomeFragment().getTarjetas();
}else{
Toast.makeText(this, "No hay conexion a internet.", Toast.LENGTH_LONG).show();
}
break;
}
return super.onOptionsItemSelected(item);
}
The menu.xml
<menu xmlns:android="http://schemas.android.com/apk/res/android"

Can some one help me to solve that?

Try this changes:
Change Your Root layout To LinearLayout or Coordinator Layout-- As framelayout sometimes consume the click event of items under it.
1.in onCreateOptionsMenu()
#Override
public boolean onCreateOptionsMenu(Menu menu) {
//Your code
return true;
}
2.And in onOptionsItemSelected() add return true
#Override
public boolean onOptionsItemSelected(MenuItem item) {
// Handle item selection
switch (item.getItemId()) {
case R.id.refresh:
// your code
return true; //add this
default:
return super.onOptionsItemSelected(item);
}
}

How to set menu items in a fragment toolbar?

I have a fragment in my Activity and the fragment has its own toolbar. Like this:
Image
Here is the layout of the fragment:
<FrameLayout 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"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context="com.hometsolutions.space.Fragments.ControlFragment">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<android.support.v7.widget.Toolbar
android:id="#+id/Setup_next_toolbar"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="?attr/colorPrimary"
android:elevation="4dp"
android:theme="#style/ThemeOverlay.AppCompat.Dark.ActionBar"
app:popupTheme="#style/ThemeOverlay.AppCompat.Light" />
<android.support.v7.widget.RecyclerView
android:id="#+id/recycler_view_setup_next"
android:layout_width="match_parent"
android:layout_height="match_parent"
app:layout_constraintTop_toBottomOf="#+id/setup_next_recycler" />
</LinearLayout>
</FrameLayout>
I want to add menu on the Setup_next_toolbar. Not on the MainActivity toolBar.
I did this on the fragment:
on the onCreate: setHasOptionsMenu(true);
then
#Override
public void onCreateOptionsMenu(Menu menu, MenuInflater inflater) {
super.onCreateOptionsMenu(menu, inflater);
inflater.inflate(R.menu.Setup_next_menu, menu);
}
but it added the menu on the MainActivity tolbar. How can I set menuItems on the Setup_next_toolbar?

may be its too late, but just solved the same issue and think you would like to know. all you nee is just set up toolbar for activity
((MainActivity) getActivity()).setSupportActionBar(toolbar);
setHasOptionsMenu(true);
this will trigger onCreateOptionsMenu in fragment

You can set an ImageView in Toolbar and open a popup menu when ImageView is clicked and them handle the menu items clicks in popup menu.
<android.support.v7.widget.Toolbar
app:layout_collapseMode="pin"
android:fitsSystemWindows="false"
android:id="#+id/toolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize">
<RelativeLayout
android:layout_width="wrap_content"
android:layout_height="match_parent>
<ImageView
android:layout_marginRight="8dp"
android:id="#+id/overflow_menu"
android:clickable="true"
android:background="?attr/selectableItemBackgroundBorderless"
app:srcCompat="#drawable/overflow_menu"
android:layout_centerVertical="true"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentRight="true"/>
</RelativeLayout>
</android.support.v7.widget.Toolbar>
Inside fragment
#Override
public void onViewCreated(View view, #Nullable Bundle savedInstanceState) {
super.onViewCreated(view, savedInstanceState);
//Other stuff
ImageView overflowMenuImageView = view.findViewById(R.id.overflow_menu);
overflowMenuImageView.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
PopupMenu popupMenu = new PopupMenu(getActivity(), view);
popupMenu.setOnMenuItemClickListener(new PopupMenu.OnMenuItemClickListener() {
#Override
public boolean onMenuItemClick(MenuItem item) {
if(item.getItemId() == R.id.menu_item_id){
//Do your thing
}
return false;
}
});
popupMenu.inflate(R.menu.my_menu);
popupMenu.show();
}
});
}

Try this:
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setHasOptionsMenu(true);
}
#Override
public void onCreateOptionsMenu(Menu menu, MenuInflater inflater) {
//TODO Add your menu entries here
inflater.inflate(R.menu.menu, menu);
super.onCreateOptionsMenu(menu, inflater);
}

How to implement MiniDrawer using mikepenz/MaterialDrawer

</android.support.design.widget.CoordinatorLayout>

#sendtodilanka the problem is that you add the Crosssfader as the parent of the main_content view, which is a direct child of your CoordinatorLayout.
As the CoordinatorLayout is similar to the FrameLayout and does overlap views your Crossfader will simply be displayed below the AppBarLayout which you have defined to be over the main_content.
To get the Crossfader below the Toolbar you should add a new View around your main_content, let's choose a FrameLayout which has the attribute (don't forget to define the appBarLayout id to your AppBarLayout)
xml
app:layout_behavior="#string/appbar_scrolling_view_behavior"
After this the Crossfader will get inflated as a child of the FrameLayout we added above, which is displayed below the AppBarLayout.
A more detailed information regarding this can be found here.
So your layout will look something like this:
