Android Toolbar Adding Menu Items for different fragments

Question

I have a toolbar as well as a navigation drawer. When I start my app, the toolbar and navigation drawer are created. When I click items in the navigation drawer, it starts new fragments and keeps the same toolbar. How do I basically add menu items to the toolbar such as search, add, edit when I start specific fragments? I don't want them at the start of the program, but created dynamically. Also, how would I be able to click these buttons and have them start other fragments. I want it so in one fragment, the edit button in the toolbar does a specific thing compared to the edit button in another fragment. Thanks!

Menu_toolbar:

<?xml version="1.0" encoding="utf-8"?> <menu xmlns:android="http://schemas.android.com/apk/res/android" xmlns:app="http://schemas.android.com/apk/res-auto">  <item android:id="@+id/edit"     android:orderInCategory="1"     android:title="Edit"     app:showAsAction="always"     android:icon="@drawable/pencil_icon"/> <item android:id="@+id/add"     android:orderInCategory="1"     android:title="Add"     app:showAsAction="always"     android:icon="@drawable/plus_icon"/> 

Toolbar:

<?xml version="1.0" encoding="utf-8"?> <android.support.v7.widget.Toolbar xmlns:android="http://schemas.android.com/apk/res/android" android:id="@+id/toolbar" android:layout_width="match_parent" android:layout_height="55dp" android:background="#10a1ff" android:title="Home" /> 

Answer 1

Add similar code to your fragments:

@Override public View onCreateView(LayoutInflater inflater, ViewGroup parent, Bundle savedInstanceState) {     View v = inflater.inflate(R.layout.library_fragment, parent, false);     setHasOptionsMenu(true);     return v; }   @Override public void onCreateOptionsMenu(Menu menu, MenuInflater inflater) {    inflater.inflate(R.menu.your_menu_xml, menu);    super.onCreateOptionsMenu(menu, inflater); } 

This way you can customize the menu for your fragments.
