When I am editing the xml layout I always get confused when choosing between the match_parent and the fill_parent, and I always end up thinking I’m doing everything wrong because I don’t know what each one of them is or if they’re the same.
One could explain the functionality of each?

What is the difference between match_parent and fill_parent ?
They are the same (in Level API 8+).
Yes, MATCH_PARENT and FILL_PARENT are just different constant names for the same integer value (-1 if you are curious) used to specify the layout mode of a View within your parent.
The fill_parent was renamed to match_parent because the problem with the old name was that it implied to affect the dimensions of the parent, while match_parent best described the resulting behaviour - the dimension corresponding to the parent.
What is the match_parent function ?
The function of match_parent is to give a special value to the height or width requested by a View.
Use match_parent because there is no difference if you are in versions of API 8+,and since mobile phones => Android 2.2 is advisable to use match_parent,but because of compatibility for previous versions still exists fill_parent.
OBS : In Android API versions from 1.6 to 2.1 it is advisable to use
fill_parentbecause usingmatch_parentin these versions certain errors occur, so in these versions of API usefill_parent.
According to the official documentation of Android itself, it specifies that are the same thing and that there is no difference in using either.

The fill_parent is no longer used, it is obsolete.
It was replaced by match_parent, you can even use the fill_parent, but it can happen some "defects" in the application.
Then it is better to use the current one which is the macth_parent.

Basically, nothing. They’re both the same thing. Documentation link here
fill_parent was renamed to match_parent in API 8 and larger. Always try using match_parent

In practice, there is no difference.
match_parent replaced fill_parent from the API Level 8.

I appreciate the detailed explanation, I think I’m going to have to make a lot of changes so now, on the right track. =)
