我的布局片段.

<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="48dp"
        android:layout_marginTop="-5dp"
        android:background="@color/white"
        android:theme="@style/toolbarMenuTheme"/>

我的膨胀布局.

<item
    android:id="@+id/web_view_reload"
    android:icon="@drawable/replay"
    android:title="Reload"
    app:showAsAction="always"/>
<item
    android:id="@+id/web_view_action"
    android:icon="@drawable/stack_icon_on"
    android:title="Stack"
    app:showAsAction="always"/>
<item
    android:id="@+id/web_view_screenshot"
    android:icon="@drawable/screenshot"
    android:title="Screenshot"
    app:showAsAction="always"/>
<item
    android:id="@+id/web_view_share"
    android:title="SHARE WEBSITE"/>
<item
    android:id="@+id/web_view_copy_url"
    android:title="Copy URL"/>

用java填充它：

Toolbar toolbar = (Toolbar) view.findViewById(R.id.toolbar);
    toolbar.setNavigationIcon(R.drawable.x);
    toolbar.inflateMenu(R.menu.web_view_toolbar_menu);

并设置单击侦听器：

toolbar.setOnMenuItemClickListener(new Toolbar.OnMenuItemClickListener() {
    @Override
    public boolean onMenuItemClick(MenuItem item) {
        ....
    }
}
