android - margin 不影响 "include"

Question

我对文章有看法。它使用“包含”，我试图在它们之间留出一点余地。但是，“android:layout_marginTop”似乎对布局没有任何影响。

我做错了什么？

<LinearLayout 
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:orientation="vertical" >    
    <include android:id="@+id/article1" layout="@layout/mainarticle" />
    <include android:id="@+id/article2" android:layout_marginTop="10dip" layout="@layout/article" />
    <include android:id="@+id/article3" android:layout_marginTop="10dip" layout="@layout/article" />
    <include android:id="@+id/article4" android:layout_marginTop="10dip" layout="@layout/article" />
    <include android:id="@+id/article5" android:layout_marginTop="10dip" layout="@layout/article" />    
</LinearLayout>

Answer 1

您应该添加 android:layout_width和 android:layout_height include 中的属性标签。否则，不考虑边距。

However, 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.
