是去precated字FILL_PARENT和match_parent之间的唯一区别 [英] Is deprecated word the only difference between fill_parent and match_parent

问题描述

我发现这两个 FILL_PARENT 和 match_parent 意味着同样的事情

I found both fill_parent and match_parent means the same thing

• FILL_PARENT 意味着视图想要成为大如其父，减去母公司的填充，如果有的话。
• match_parent 意味着视图想要成为大如其父，减去母公司的填充，如果有的话。

• fill_parent means that the view wants to be as big as its parent, minus the parent's padding, if any.
• match_parent means that the view wants to be as big as its parent, minus the parent's padding, if any.

只有一个区别，我发现这是 FILL_PARENT 是德precated从API级别8日起，代之以 match_parent

Only One difference I found that is fill_parent is deprecated starting from API Level 8 and is replaced by match_parent

不过，在创建布局，我没有注意到这两者之间有什么区别。如果两者是相同的，为什么FILL_PARENT是德precated。任何人都可以表明，这两种或FILL_PARENT和WRAP_CONTENT之间的任何区别，除了去precated字之间的实际差异。

But while creating layout I didn't notice any difference between these two. If both are the same then why fill_parent is deprecated. Can anyone show any practical difference between these two or any other difference between fill_parent and wrap_content except deprecated word.

推荐答案

至于你说他们是完全一样的。正如罗曼·盖伊说，他们已经改变了名字，因为FILL_PARENT混淆了开发人员。作为事实事，FILL_PARENT不填充剩余空间（即使用权重属性），但它需要尽可能多的空间作为其布局父。这就是为什么新的名为match_parent。

As you said they are exact the same. As Romain Guy said, they have changed the name because "fill_parent" was confusing for developers. As matter of the fact, "fill_parent" does not fill the remaining space (for that you use the weight attribute) but it takes as much space as its layout parent. That's why the new name is "match_parent".
