If I have specific “android:layout_height” with certain height on a style, will child layout need to specific

Question

I have following questions relate to style and its children who will inherit its style.

Parent:

40dip 0dp 0.5

Children:

            ***<item name="android:layout_height">wrap_content</item>***
    <item name="android:layout_width">fill_parent</item>
    <item name="android:layout_gravity">center_vertical</item>
    <item name="android:layout_marginBottom">3dip</item>
    <item name="android:gravity">center_vertical</item>
    <item name="android:textSize">21dip</item>  

In the children style, if I include ,wrap_content

it will override the parent 40 to name="android:layout_height">wrap_content

So, in this case , in the children style do i need to include fill_parents or something else.

So far, i have removed it without specify any layout_height...it works fine.

Please let me know if you have any suggestion on my implementation.

Thanks.

嗯，我想是因为您已经给父级提供了最大高度并在子级中包装了内容...因此，如果有大于40 dp的内容大于要包装的内容，则会自动到达下一行，将其他内容稍微向下推。
