现在我想在我的一个活动中将工具栏显示在我的内容之上.
但是,我无法让它发挥作用.这是我到目前为止：

活动布局：

<LinearLayout
    android:id="@+id/main_parent_view"
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical"
    android:theme="@style/myAppTheme">
    <include layout="@layout/toolbar_setlist_top"/>
    <ImageView
        android:id="@+id/image"
        android:layout_height="match_parent"
        android:layout_width="match_parent"/>
</LinearLayout>

工具栏布局：

<android.support.v7.widget.Toolbar
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:id="@+id/toolbar"
    app:theme="@style/MyActionBar"
    app:popupTheme="@style/MyActionBar"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:minHeight="?attr/actionBarSize"
    android:layout_marginTop="0dp" />

主题：

<resources>
    <style name="myAppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
        <item name="colorPrimary">@color/primaryColor</item>
        <item name="colorPrimaryDark">@color/primaryColorDark</item>
        <item name="android:windowNoTitle">true</item>
        <item name="windowActionBar">false</item>
        <item name="drawerArrowStyle">@style/DrawerArrowStyle</item>
        <item name="android:activatedBackgroundIndicator">@drawable/list_selector</item>
        <item name="actionBarStyle">@style/MyActionBar</item>
    </style>

    <style name="DrawerArrowStyle" parent="Widget.AppCompat.DrawerArrowToggle">
        <item name="spinBars">true</item>
        <item name="color">@android:color/white</item>
    </style>

    <style name="MyActionBar" parent="@style/Widget.AppCompat.ActionBar">
        <item name="android:background">@color/primaryColor2</item>
        <item name="android:windowActionBarOverlay">true</item>
        <!-- Support library compatibility -->
        <item name="background">@color/primaryColor2</item>
        <item name="windowActionBarOverlay">true</item>
    </style>
</resources>

码：

@Override
protected void onCreate(Bundle savedInstanceState) {
    requestWindowFeature(Window.FEATURE_ACTION_BAR_OVERLAY);
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_setlist);
    toolbar = (Toolbar) findViewById(R.id.toolbar);
    setSupportActionBar(toolbar);
}
