Answer 1

If i have understood your question correctly i guess u want to add "include.xml" in your include tag in main.xml . For that modify your include part as:

<include
            android:id="@+id/in_header"
            layout="@layout/include"
            android:layout_width="match_parent"
            android:layout_height="wrap_content">
</include>

Answer 2

去掉 id 标签中的下划线并尝试清理

android:id="@+id/inHeader"
