Android2.2中match_parent和fill_parent是一個意思

標題裏已經把這個意思表達清楚了，兩個參數意思一樣，只是某大牛覺得match_parent更貼切，於是從2.2開始你兩個詞都可以用。那麼如果考慮低版本的使用情況你就需要用fill_parent了。

下面是兩者相同的證據，看android.view.ViewGroup裏的靜態嵌套類LayoutParams中的代碼：

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.
       */
