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: 01public 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 */ |
