Android UI：Layout 自定义标题栏

1.创建自己的标题栏样式，代码如下：

<resources>
<!-- 自定义的标题栏 -->
    <style name="CustomWindowTitleBackground"> 
        <item name="android:background">#836FFF</item> 
    </style> 
    <style name="CustomTitleBar" parent="android:Theme"> 
        <item name="android:windowTitleSize">32dp</item> 
        <item name="android:windowTitleBackgroundStyle">@style/CustomWindowTitleBackground</item> <!--设置titlebar的背景-->
    </style> 


    <style name="styleName">
        <item name="android:orientation">horizontal</item>
    </style>
    
</resources>

2.新建一个layout文件，如mycustomtitle.xml

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="45dp"
    android:background="@color/blue" >

    <ImageButton
        android:id="@+id/share"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_centerVertical="true"        
        android:layout_alignParentRight="true"
        android:src="@drawable/share"
        android:background="@color/blue"
        android:contentDescription="@string/share" 
        android:paddingRight="5dp"/>
    

    <ImageButton
        android:id="@+id/back"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignParentLeft="true"
        android:layout_centerVertical="true"
        android:contentDescription="@string/back"
        android:src="@drawable/back"
        android:background="@color/blue"
        android:padding="5dp" />

    <TextView
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:layout_alignParentLeft="true"
        android:layout_alignParentTop="true"
        android:gravity="center"
        android:text="@string/title"
        android:textColor="#fff"
        android:textSize="20sp"
        android:textStyle="bold" />

</RelativeLayout>

效果如图所示

3.在AndroidManifest.xml中，做如下修改

 <application
        android:allowBackup="true"
        android:icon="@drawable/app"
        android:label="@string/app_name"
        android:theme="@style/CustomTitleBar" >

4.在Java中调用该标题的方法，如下：注意代码的顺序，很重要

protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        requestWindowFeature(Window.FEATURE_CUSTOM_TITLE);
        setContentView(R.layout.activity);        
        getWindow().setFeatureInt(Window.FEATURE_CUSTOM_TITLE,R.layout.mycustomtitle); 

}
