How to set menu to Toolbar in Android

I want use ToolBar instead of ActionBar, but don't show me menu in toolbar!!! i want set menu such as Refresh or Setting buttons in ActionBar.

Toolbar.xml code :

<?xml version="1.0" encoding="utf-8"?>
<android.support.v7.widget.Toolbar
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:background="?attr/colorPrimary"
    android:minHeight="?attr/actionBarSize"
    app:navigationContentDescription="@string/abc_action_bar_up_description"
    app:popupTheme="@style/ThemeOverlay.AppCompat.Light"
    app:theme="@style/ThemeOverlay.AppCompat.Dark.ActionBar"
    app:title="Main Page"
    android:gravity="center"/>

MainPage.java code:

public class MainPage extends AppCompatActivity {
    private Toolbar toolbar;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main_page);

        toolbar = (Toolbar) findViewById(R.id.main_toolbar);
        setSupportActionBar(toolbar);
        if (getSupportActionBar() != null) {
            getSupportActionBar().setTitle("Main Page");
        }
        toolbar.setSubtitle("Test Subtitle");
        toolbar.inflateMenu(R.menu.main_menu);
    }
}

main_menu.xml code :

<?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/menu_main_setting"
        android:icon="@drawable/ic_settings"
        android:orderInCategory="100"
        app:showAsAction="always"
        android:actionLayout="@layout/toolbar"
        android:title="Setting" />

    <item
        android:id="@+id/menu_main_setting2"
        android:icon="@drawable/ic_settings"
        android:orderInCategory="200"
        app:showAsAction="always"
        android:actionLayout="@layout/toolbar"
        android:title="Setting" />

</menu>

How to fix this problem and show menu in Toolbar ? thanks all dears <3

just override onCreateOptionsMenu like this in your MainPage.java

@Override
public boolean onCreateOptionsMenu(Menu menu) {
    // Inflate the menu; this adds items to the action bar if it is present.
    getMenuInflater().inflate(R.menu.main_menu, menu);
    return true;
}
