merge和include的区别是
<merge xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent" >
<LinearLayout
android:id="@+id/view_content"
android:layout_width="match_parent"
android:layout_height="100dp"
android:background="#4169E1"
android:orientation="horizontal" >
</LinearLayout>
<!--more-->
<RelativeLayout
android:id="@+id/view_todo"
android:layout_width="100dp"
android:layout_height="match_parent"
android:background="#800080" >
</RelativeLayout>
</merge>
引用必须是这样的:
View v = inflater.inflate(R.layout.el_marge, itemGroup, true);
否则报错:<merge /> can be used only with a valid ViewGroup root and attachToRoot=true
也就是说:merge是为了减少include里的根ViewGroup,那么inflate的marge必须放到ViewGroup中。
