1.首先在onCreate方法里定义
@Override
protected void onCreate(Bundle savedInstanceState) {}
2.在res/layout里新建title.xml文件
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >
<TextView
android:id="@+id/gallery_title_name"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="××××"
android:textColor="#ffffff"
android:textStyle="bold"
android:textSize="20dp"/>
</LinearLayout>
3.再在res/values里新建style.xml
<?xml version="1.0" encoding="utf-8"?>
<resources>
<style name="CustomWindowTitleBackground">
<item name="android:background">@drawable/bg</item> <!--bg为标题的背景图片.9.png格式-->
</style>
<style name="CustomTitleBar" parent="android:Theme">
<item name="android:windowTitleSize">45dp</item>
<item name="android:windowTitleBackgroundStyle">@style/CustomWindowTitleBackground</item> <!--设置titlebar的背景-->
</style>
</resources>
4.最后在androidManifest.xmlwenj
<activity
android:name="com.xyscience.lr.mainUI.GalleryDetails"
android:theme="@style/CustomTitleBar" >
</activity>
OK,大功告成!
