首先，修改標題欄的寬度和背景，在strings.xml中新增：

    <item name="android:background">@drawable/title_bg</item> 
</style> 

<style name="test" parent="android:Theme"> 
    <item name="android:windowTitleSize">40dp</item> 
    <item name="android:windowTitleBackgroundStyle">@style/CustomWindowTitleBackground</item> 
</style>
 

<activity android:name=".MainActivity" 
                android:theme="@style/test"> 
          <intent-filter> 
              <action android:name="android.intent.action.MAIN" /> 
              <category android:name="android.intent.category.LAUNCHER" /> 
          </intent-filter> 
      </activity>
 

      接著修改MainActivity：

public void onCreate(Bundle savedInstanceState) { 
       super.onCreate(savedInstanceState); 
       requestWindowFeature(Window.FEATURE_CUSTOM_TITLE); //宣告使用自定義標題 
       setContentView(R.layout.main); 
       getWindow().setFeatureInt(Window.FEATURE_CUSTOM_TITLE, R.layout.title);//自定義佈局賦值 
   }
 

<?xml version="1.0" encoding="utf-8"?> 
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" 
android:orientation="horizontal" android:layout_width="fill_parent" 
android:layout_height="fill_parent"> 

<ImageView android:layout_width="wrap_content" 
android:layout_centerVertical=’true’ 
android:layout_height="wrap_content" 
android:src="@drawable/ic_launcher_email" /> 
<TextView android:layout_width="wrap_content" 
android:layout_centerInParent="true" 
android:layout_height="wrap_content" 
android:text="自定義標題欄" /> 

</RelativeLayout>
