Android的动作栏没有显示在displayOptions - useLogo [英] Android Action Bar not showing on displayOptions - useLogo

问题描述

我有一个 actionBarStyle ，我已经实现了我的应用程序为我的动作条。这是下面的XML code：

I have an actionBarStyle that I have implemented in my app for my ActionBar. Here is the xml code below:

<resources xmlns:android="http://schemas.android.com/apk/res/android">
    <style name="MyActionBarTheme" parent="@android:style/Theme.Holo">
        <item name="android:windowActionBarOverlay">true</item>
        <item name="android:actionBarStyle">@style/MyCustomActionBar</item>
    </style>
    <style name="MyCustomActionBar" parent="@android:style/Widget.Holo.ActionBar">
        <item name="android:background">@android:color/transparent</item>
        <item name="android:backgroundSplit">@android:color/transparent</item>
        <item name="android:displayOptions">useLogo</item>
    </style>

和这里是我的活动的OnCreate ：

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    getActionBar().setLogo(R.drawable.ic_logo);
    setContentView(R.layout.activity_home);

    initializeViews();
    manageFragments();
}

现在的问题是，我的动作条根本不显示，当我从删除 displayOptions 项目我XML。它显示的标题。现在我可以随时删除标题（设置标题字符串只是空白），但我不希望如此，因为它显示了默认的动作条风格/主题为几秒钟，那么我的自定义主题（我想你知道这一个）。我不知道是什么问题。请帮忙。谢谢...

The Problem is that my ActionBar doesn't show at all and when I remove the displayOptions item from My XML. It shows with the title. Now I can always remove the title (set the title string to just blank) but I don't want that as it shows the default ActionBar style/theme for a few seconds and then my custom theme (I guess you know this one). I don't know what the problem is. Please help. Thanks...

推荐答案

如果您设置了安卓标志的主题，你不应该需要将其设置在$ C $℃。

If you set the android:logo in the theme you shouldn't need to set it in code.

我想你可能还需要 showHome 在你的显示选项，例如

I think you may also need showHome in your display options e.g.

<item name="android:displayOptions">showHome|useLogo</item>

修改

下面是一个例子主题，我用它来隐藏的标志和，该样本是使用显示在操作栏中的标题 ActionBarSherlock 所以你需要调整父样式名称相应地，如果你不使用它。

Below is an example theme I use to hide the logo and display the title in the action bar, this sample is using ActionBarSherlock so you will need to adjust the parent style names accordingly if you aren't using it.

<style name="AppTheme" parent="style/Theme.Sherlock.Light.DarkActionBar">
   <item name="android:windowBackground">@color/background_primary</item>
   <item name="android:icon">@drawable/appicon</item>    
   <!-- For the home as up icon on sub pages -->
   <item name="android:homeAsUpIndicator">@drawable/back</item>
   <item name="homeAsUpIndicator">@drawable/back</item>          
   <item name="android:actionBarStyle">@style/AppTheme.ActionBar</item>
   <item name="actionBarStyle">@style/AppTheme.ActionBar</item>
</style>

<style name="AppTheme.ActionBar" parent="Widget.Sherlock.Light.ActionBar.Solid.Inverse">
<item name="android:displayOptions">showTitle</item>
<item name="displayOptions">showTitle</item>

<item name="android:titleTextStyle">@style/AppTheme.ActionBar.TitleTextStyle</item>
<item name="titleTextStyle">@style/AppTheme.ActionBar.TitleTextStyle</item>    
<item name="android:background">@color/actionbar_bg_color</item>
<item name="background">@color/actionbar_bg_color</item>
<item name="android:backgroundStacked">@color/actionbar_bg_color</item>
<item name="backgroundStacked">@color/actionbar_bg_color</item>
