Visibility属性中invisible和gone 区别
http://developer.android.com/reference/android/view/View.html#attr_android:visibility
下面是Android Developers上面介绍它们的区别：
android:visibility
Controls the initial visibility of the view.
Must be one of the following constant values.
| Constant | Value | Description |
|---|---|---|
visible
|
0 | Visible on screen; the default value. |
invisible
|
1 | Not displayed, but taken into account during layout (space is left for it). |
gone
|
2 | Completely hidden, as if the view had not been added. |
This corresponds to the global attribute resource symbol visibility.
