Android2.2中match_parent和fill_parent是一个意思

<!-- Content -->

两个参数意思一样，只是觉得match_parent更贴切，于是从2.2开始你两个词都可以用。那么如果考虑低版本的使用情况你就需要用fill_parent了。

下面是两者相同的证据，看android.view.ViewGroup里的静态嵌套类LayoutParams中的代码：

public static final int FILL_PARENT = -1;      /**       * Special value for the height or width requested by a View.       * MATCH_PARENT means that the view wants to be as big as its parent,       * minus the parent's padding, if any. Introduced in API Level 8.       */      public static final int MATCH_PARENT = -1;       /**       * 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.       */
