Because you're using NoActionBar theme, so there's no action bar in your activity . In order to show your menu in your activity, the best method is adding Toolbar as your actionbar as this Google Guide - Set up the app bar :

// add toolbar to your layout xml
<android.support.v7.widget.Toolbar
android:id="@+id/my_toolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
android:background="?attr/colorPrimary"
android:elevation="4dp"
android:theme="@style/ThemeOverlay.AppCompat.ActionBar"
app:popupTheme="@style/ThemeOverlay.AppCompat.Light"/>


// set toolbar as actionbar in your activity
Toolbar myToolbar = (Toolbar) findViewById(R.id.my_toolbar);
setSupportActionBar(myToolbar);
