Android2.2中match_parent和fill_parent是一个意思03 Sep
标题里已经把这个意思表达清楚了，两个参数意思一样，只是某大仙觉得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：
01
public static final int FILL_PARENT = -1;02 /**
03 * Special value for the height or width requested by a View.
04 * MATCH_PARENT means that the view wants to be as big as its parent,
05 * minus the parent's padding, if any. Introduced in API Level 8.
06 */
07
public static final int MATCH_PARENT = -1;08 /**
09 * Special value for the height or width requested by a View.
10 * WRAP_CONTENT means that the view wants to be just large enough to fit
11 * its own internal content, taking its own padding into account.
12 */
