如何将xml导入另一个xml？

Question

I have 2 xml files, and in the first file need to do the import second file, I tried to do it with Xinclude :

first.xml:

<FirstXml name="first" xmlns:xi="http://www.w3.org/2001/XInclude">
    <xi:include href="second.xml"/>
</FirstXml>

second.xml

<SecondXml name="second>
  ...
</SecondXml>

Then I tried to create an instance of a DocumentBuilderFactory and to enable XInclude processing.

DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
factory.setXIncludeAware(true);

But when I try to enable the XInclude processing throws an UnsupportedOperationException.

The documentation says that this exception throws when implementations for earlier versions of JAXP is used.

How can I fix this problem? Or how I can do such import in android?

Answer 1

 <include
    layout="@layout/app_bar_starting"
    android:layout_width="match_parent"
    android:layout_height="match_parent" 

you can try these to import the second layout.

Answer 2

只需将以下行写在first.xml文件中

<include layout="@layout/custom_layout" />
