即使最小 SDK 版本设置为 11，ActionBar 也不会创建

我的最小 SDK 版本设置为 11，目标 SDK 版本设置为 11。我有一个包含一些片段的活动。该样式具有 parent="@android:style/Theme.Light" 并且不会隐藏操作栏。在我希望看到操作栏的活动中，我重写了 onCreateOptionsMenu()。我的理解是，当活动启动时， onCreateOptionsMenu() 将自动被调用，这将创建操作栏。这不会发生在我身上。我不确定我的理解是否错误，或者我是否做错了什么导致它不显示。

需要明确的是，我的 onCreateOptionsMenu 方法甚至没有触发。我怀疑问题出在代码的另一部分，但我不知道它可能是什么。

@Override
public boolean onCreateOptionsMenu(Menu menu) {
    MenuInflater inflater = getMenuInflater();
    inflater.inflate(R.menu.signin_layout_menu, menu);
    return true;
}

这是我的菜单 xml：

<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:id="@+id/menu_signin_layout"
         android:title="stuff"
         android:showAsAction="ifRoom|withText" />
</menu>

这是 Activity 使用的样式：

<style name="Theme.MyTheme" parent="@android:style/Theme.Light">
    <!-- Window attributes -->
    <item name="android:windowTitleSize">36dip</item>
    <item name="android:windowTitleStyle">@style/WindowTitle</item>
    <item name="android:windowTitleBackgroundStyle">@style/WindowTitleBackground</item>

    <item name="android:textAppearanceButton">@style/TextAppearance.Widget.Button</item>

    <!-- Button styles -->
    <item name="android:buttonStyle">@style/Widget.Button</item>
</style>

原文

I have my min SDK version set to 11 and my target SDK version set to 11. I have an activity with some fragments in it. The style has parent="@android:style/Theme.Light" and doesn't hide the actionbar. In the activity where I expect to see the actionbar, I have an override of onCreateOptionsMenu(). My understanding is that onCreateOptionsMenu() will automatically be called when the activity starts and that will create the actionbar. This is not happening for me. I'm not sure if my understanding is wrong or if I'm doing something wrong that is causing it not to show up.

To be clear, my onCreateOptionsMenu method is not even firing. I suspect the problem is in another part of the code, but I don't know what it could be.

@Override
public boolean onCreateOptionsMenu(Menu menu) {
    MenuInflater inflater = getMenuInflater();
    inflater.inflate(R.menu.signin_layout_menu, menu);
    return true;
}

Here is my menu xml:

<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:id="@+id/menu_signin_layout"
         android:title="stuff"
         android:showAsAction="ifRoom|withText" />
</menu>

Here is the style that activity is using:

<style name="Theme.MyTheme" parent="@android:style/Theme.Light">
    <!-- Window attributes -->
    <item name="android:windowTitleSize">36dip</item>
    <item name="android:windowTitleStyle">@style/WindowTitle</item>
    <item name="android:windowTitleBackgroundStyle">@style/WindowTitleBackground</item>

    <item name="android:textAppearanceButton">@style/TextAppearance.Widget.Button</item>

    <!-- Button styles -->
    <item name="android:buttonStyle">@style/Widget.Button</item>
</style>
