android自定义标题栏的时候,使用下面方法：

1.  requestWindowFeature(Window.FEATURE_CUSTOM_TITLE);  
2.         setContentView(R.layout.main);  
3.         getWindow().setFeatureInt(Window.FEATURE_CUSTOM_TITLE,R.layout.mycustomtitle);  
4.     }  

原因：

因为在manifest文件里使用了

 android:theme="@style/AppTheme" >

解决方法：

在style.xml中修改加入这句“ <item name="android:windowActionBar">false</item>” 如下：

<span style="color:#333333;"><resources>

    <!--
        Base application theme, dependent on API level. This theme is replaced
        by AppBaseTheme from res/values-vXX/styles.xml on newer devices.
    -->
    <style name="AppBaseTheme" parent="android:Theme.Light">
        <!--
            Theme customizations available in newer API levels can go in
            res/values-vXX/styles.xml, while customizations related to
            backward-compatibility can go here.
        -->
    </style>

    <!-- Application theme. -->
    <style name="AppTheme" parent="AppBaseTheme">
        <!-- All customizations that are NOT specific to a particular API-level can go here. -->
        </span><span style="color:#ff0000;"><item name="android:windowActionBar">false</item> </span><span style="color:#333333;"> 
    </style>

</resources></span>
