Android的，如何将XML文件转换为另一个XML文件？ [英] android, How to include an XML file into another XML file?

问题描述

我有一个header_bar.xml文件，其code是：

I have a header_bar.xml file that its code is:

<?xml version="1.0" encoding="utf-8"?>

<RelativeLayout
    xmlns:android         = "http://schemas.android.com/apk/res/android"
    android:layout_width  = "fill_parent"
    android:layout_height = "wrap_content"
    android:background    = "@drawable/bar_top"
    android:layout_alignParentTop = "true" >


    <Button
        android:id                      = "@+id/btn_menu_settings"
        android:layout_width            = "wrap_content"
        android:layout_height           = "wrap_content"
        android:layout_alignParentRight = "true"
        android:layout_centerVertical   = "true"
        android:background              = "@drawable/btn_header_settings"
        android:text                    = "@string/menu_btnSetting"
        android:layout_marginRight      = "20dip"
        android:textColor               = "#F9F9F6" />

    <!-- The text of this button depends of which activity we are, may be change to "Back" or "Menu" -->
    <Button
        android:id                      = "@+id/btn_menu_compound"
        android:layout_width            = "wrap_content"
        android:layout_height           = "wrap_content"
        android:layout_alignParentLeft  = "true"
        android:layout_centerVertical   = "true"
        android:background              = "@drawable/btn_header_menu"
        android:text                    = "@string/menu_btnMenu"
        android:layout_marginLeft       = "20dip"
        android:textColor               = "#F9F9F6" />


</RelativeLayout>

现在，我想将它添加到另一个XML文件。我写了这个code：

Now, I want to add it to another XML file. I have written this code:

<?xml version="1.0" encoding="utf-8"?>

<RelativeLayout
    xmlns:android         = "http://schemas.android.com/apk/res/android"
    android:layout_width  = "fill_parent"
    android:layout_height = "fill_parent"
    android:orientation   = "vertical" >


    <!-- Loading header of this UI which is coded separately -->
    <include
        android:id="@+id/header" 
        layout="@layout/header_bar" />



    <GridView 
        android:id="@+id/news_gridview"
        android:layout_width="fill_parent" 
        android:layout_height="fill_parent"
        android:layout_below="@id/header"
        android:layout_marginTop="25dip"
        android:layout_centerInParent="true"
        android:numColumns="2"
        android:verticalSpacing="5dp"
        android:horizontalSpacing="5dp"
        android:background="@drawable/bg" />  


    <!-- Loading footer of this UI which is coded separately -->
    <include layout="@layout/footer_gallery" /> 

</RelativeLayout>  

编译器显示我下面的错误在错误日志中：您必须specifiy有效的布局参考。布局ID @布局/ header_bar是无效的。

我惊讶，为什么它不工作。我检查R档，并有header_bar在R.layout。

I amazed why it doesn't work. I checked R file and it had header_bar in its R.layout .

任何建议AP preciated。谢谢

Any suggestion appreciated. Thanks

======================= Update

我刚刚重新启动Eclipse和现在它的确定。跆拳道是这个编译器？

I just restarted the Eclipse and now its ok. wtf is this compiler?

推荐答案

中设置一个XML布局（假设header_bar）后，试试这个：

Try this after setting one xml layout (suppose header_bar) :

LayoutInflater inflater = getLayoutInflater();
getWindow().addContentView(inflater.inflate(R.layout.main, null), new ViewGroup.LayoutParams(ViewGroup.LayoutParams.FILL_PARENT,ViewGroup.LayoutParams.FILL_PARENT));
