原标题:Android ActionBar isn t created

I m currently working on a mp3 library on Android. Thing is, there are 4 tab, representing Songs, Albums, Artists and Playlists. My main activity creates a tabspec for each tab and add them to a tabhost. The problem is, I can t use the ActionBar. I tried the tutorial from Android Developpers and it works fine, however when I try to apply it on my project it doesn t work. I can t see the actionbar and if I try a getActionBar() in my activity it returns null.

正如在教程里我把这个代码 输入到活动中:

@Override    
public boolean onCreateOptionsMenu(Menu menu) {
    getMenuInflater().inflate(R.menu.actionbar_menu, menu);
    return true;
}

我创造了这个菜单:

<?xml version="1.0" encoding="utf-8"?>

<menu xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:id="@+id/menu_save"
          android:title="Hello !"
          android:showAsAction="ifRoom" />
</menu>

我想为了显示动作栏,还有很多事情要做, 但我现在无法在网络上找到准确的信息...这和我的主要活动Xml有关吗?

谢谢大家的注意

最佳回答

动作栏只能从Android 3. 0及以上处获取, 您需要将您的应用程序主题设置为 Holo 。

除了设置 sdk 版本外, 例如 :

<uses-sdk android:minSdkVersion="11" android:targetSdkVersion="15"/> 

您也必须使应用程序主题使用Holo

问题回答

我 在 外 列 上 加 上 了 些 字

android:theme="@android:style/Theme.Holo.Light.DarkActionBar" >

希望这样能节省一些时间 不必再查了

make and mid:minSdkVersion="14" 它为我工作。
