Android中的FILL_PARENT与WRAP_CONTENT的区别

Android中的FILL_PARENT与WRAP_CONTENT的区别

 

 

FILL_PARENT

 

Special value for the height or width requested by a View. FILL_PARENT means that the view wants to be as big as its parent, minus the parent's padding, if any. This value is deprecated starting in API Level 8 and replaced by MATCH_PARENT .

 

fill_parent布局指将视图扩展以填充所在容器（也就是父容器）的全部空间。

WRAP_CONTENT

 

Special value for the height or width requested by a View. WRAP_CONTENT means that the view wants to be just large enough to fit its own internal content, taking its own padding into account.

 

wrap_content布局指根据视图内部内容自动扩展以适应其大小。
