没有区别,一个新版本,一个旧版本,从Android 2.2开始fill_parent改名为match_parnet,建议使用match_parnet。
没有区别 可以参看www.developer.android.com/reference/android/view/ViewGroup.LayoutParams.html
FILL_PARENT (renamed MATCH_PARENT in API Level 8 and higher), which means that the view wants to be as big as its parent (minus padding)
从API8开始,fill_parent改名为match_parent,一般建议使用match parent
