<include>Includes a layout file into this layout.
类似 #include ，把layout展开在include处attributes:
layoutLayout resource. Required. Reference to a layout resource.android:idResource ID. Overrides the ID given to the root view in the included layout.android:layout_heightDimension or keyword. Overrides the height given to the root view in the included layout. Only effective if android:layout_width is also declared.android:layout_widthDimension or keyword. Overrides the width given to the root view in the included layout. Only effective if android:layout_height is also declared.You can include any other layout attributes in the <include> that are supported by the root element in the included layout and they will override those defined in the root element.
注意，findViewById()都是父容器找子控件，被include的 layout里的控件要在都位于主layout中，所以要用 主layout对应的view.findViewById()才能找到子layout中的控件。Caution:
If you want to override layout attributes using the <include> tag, you must override both android:layout_height and android:layout_width in order for other layout attributes to take effect.
Another way to include a layout is to use ViewStub. It is a lightweight View that consumes no layout space until you explicitly inflate it, at which point, it includes a layout file defined by itsandroid:layout attribute. For more information about using ViewStub, read Loading Views On Demand.
主layout: frgmt_main.xml
1 <FrameLayout 2 android:id="@android:id/tabcontent" 3 android:layout_width="match_parent" 4 android:layout_height="match_parent"> 5 6 <!-- tab1,用include可以引用别处的layout --> 7 <include 8 android:id="@+id/tab_weixin" 9 10 android:layout_width="wrap_content" 11 android:layout_height="wrap_content" 12 layout="@layout/tab_weixin_layout" />被include的layout ： tab_weixin_layout.xml
