（转）Android 自定义标题栏（title栏）

转：http://blog.csdn.net/jamin0107/article/details/6715678

第一步，向实现自定义标题栏，需要在onCreate方法里这样写

 

 　　 requestWindowFeature(Window.FEATURE_CUSTOM_TITLE);  
        setContentView(R.layout.main);
        getWindow().setFeatureInt(Window.FEATURE_CUSTOM_TITLE, R.layout.title_bar);

 

 

注意：

     　requestWindowFeature要在setContentView之前

　　　 etWindow().setFeatureInit最好在setContentView之后

 

第二步，就是写好自己的布局文件，实现标题栏的自定义。

不过我们会遇到一些问题，就是标题栏的高度不能自定义～下面就是解决办法～

下面，我们看一下android title标题栏 在源码 framework中的XML文件

screen_custom_title.xml

<LinearLayout android:orientation="vertical" android:fitsSystemWindows="true">
<FrameLayout android:id="@android:id/title_container" 
&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;android:layout_width="match_parent" 
&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;android:layout_height="?android:attr/windowTitleSize" 
&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;style="?android:attr/windowTitleBackgroundStyle">
    </FrameLayout>
<FrameLayout android:id="@android:id/content" 
&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;android:layout_width="match_parent" 
&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;android:layout_height="0dip" 
&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;android:layout_weight="1" 
&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;android:foregroundGravity="fill_horizontal|top" 
&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;android:foreground="?android:attr/windowContentOverlay"/>
</LinearLayout>

screen_title.xml

<LinearLayout android:orientation="vertical" android:fitsSystemWindows="true">
−
<FrameLayout android:layout_width="match_parent" 
&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;android:layout_height="?android:attr/windowTitleSize" 
&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;style="?android:attr/windowTitleBackgroundStyle">
<TextView android:id="@android:id/title" 
&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; style="?android:attr/windowTitleStyle" 
&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; android:background="@null" 
&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; android:fadingEdge="horizontal" 
&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; android:gravity="center_vertical" 
&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; android:layout_width="match_parent" 
&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; android:layout_height="match_parent"/>
</FrameLayout>
<FrameLayout android:id="@android:id/content" 
&nbsp; &nbsp; &nbsp; &nbsp; &nbsp;&nbsp; &nbsp; android:layout_width="match_parent" 
&nbsp; &nbsp; &nbsp; &nbsp; &nbsp;&nbsp; &nbsp; android:layout_height="0dip" 
&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;&nbsp; android:layout_weight="1" 
&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;android:foregroundGravity="fill_horizontal|top" 
&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;android:foreground="?android:attr/windowContentOverlay"/>
</LinearLayout>

       既然是自定义标题，那我们就看screen_custom_title.xml，里面有一个title_container和一个content，组合成了标题栏，我们自定义标题所给出的view，都被content作为子view了，影响不了那个title_container和content，所以，任你怎么弄，它该留白的还是留白，你没招。
       看title_container有个style是这样的：

        style="?android:attr/windowTitleBackgroundStyle"
      

         content的foreground是这样的android:foreground="?android:attr/windowContentOverlay"

       我们可以自己写一个style

<resources xmlns:android="http://schemas.android.com/apk/res/android">


<style name="CustomWindowTitleBackground">
       <item name="android:background">#00cc00</item>
</style>


<style name="title_bar" parent="android:Theme">
     <item name="android:windowTitleSize">50dp</item>
     <item name="android:windowTitleBackgroundStyle">@style/CustomWindowTitleBackground</item>
</style>
</resources>

加入到AndroidManifest

  <activity android:name=".CustomTitileBarActivity"  
                  android:label="@string/app_name" android:theme="@style/title_bar">  
            <intent-filter>  
                <action android:name="android.intent.action.MAIN" />  
                <category android:name="android.intent.category.LAUNCHER" />  
            </intent-filter>  
  </activity>  

 

PS：做的略显粗糙，不过以能实现功能为主
