android - 覆盖 xml

Question

是否可以在标签中覆盖 xml 中的属性？

父级.xml

<?xml version="1.0" encoding="utf-8"?>
<TableLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent" >
    <include  
        layout="@layout/button"
         android:text="HAHAHAH"
         />
</TableLayout>

按钮.xml:

    <?xml version="1.0" encoding="utf-8"?>
   <TextView  xmlns:android="http://schemas.android.com/apk/res/android"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:text="some string" />

是否可以将“某个字符串”更改为“哈哈哈”？

Answer 1

是和否:)"is"，因为您通常可以覆盖 XML 中的属性，“否”是因为在这种情况下，只有更改 android:layout_* 属性才会生效:

You can also override all the layout parameters (any android:layout_* attributes) of the included layout's root view by specifying them in the tag. For example:

<include android:id=”@+id/news_title”
         android:layout_width=”match_parent”
         android:layout_height=”match_parent”
         layout=”@layout/title”/>

However, if you want to override layout attributes using the tag, you must override both android:layout_height and android:layout_width in order for other layout attributes to take effect.
