如果在程序中多次用到一部分相同的布局,可以先将这部分布局定义为一个单独的XML,然后在需要的地方通过<include>引入,如下:
main.xml

使用Android include时需要注意的是要指定宽高属性,要不可能会出现一些意想不到的效果,比如引用了三次,而界面上只显示了一个item。
另一篇:
在一个项目中我们可能会需要用到相同的布局设计,如果都写在一个xml文件中,代码显得很冗余,并且可读性也很差,所以我们可以把相同布局的代码单独写成一个模块,然后用到的时候可以通过<include /> 标签来重用layout代码。
app_title.xml:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout android:id="@+id/titleLayout"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:background="@drawable/bt" xmlns:android="http://schemas.android.com/apk/res/android">
<TextView android:text="@string/login"
android:id="@+id/title" android:textSize="20px"
android:textColor="@color/white"
android:layout_width="wrap_content"
android:layout_centerInParent="true"
android:layout_height="wrap_content"/>
<Button android:text="返回"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentRight="true"
android:focusable="false"
android:textColor="@color/white"
android:background="@drawable/okbutton"
android:layout_marginRight="3px"/> </RelativeLayout>
app_tradelogin.xml:

<!-- android:layout_below与 android:layout_above 是必须设置的,否则界面不规则,不设置android:layout_above本界面没有滑动效果-->

<include layout="@layout/app_tradelogin"/> <include layout="@layout/app_bottom"/> </RelativeLayout>
效果如下:
