红米5a手机使用说明书:Android2.2中match_parent和fill_parent是一个意思

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   /**10    * Special value for the height or width requested by a View.11    * WRAP_CONTENT means that the view wants to be just large enough to fit12    * its own internal content, taking its own padding into account.13    */
