fill_parent與wrap_content的區別

Android中的FILL_PARENT與WRAP_CONTENT的區別：

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布局指將視圖擴充以填充所在容器（也就是父容器）的全部空間。

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布局指根據視圖內部內容自動擴充以適應其大小。
