When editing the xml layout I always get confused when choosing between match_parent and fill_parent , and I end up always thinking that I'm doing everything wrong because I do not know what each one is or if they are the same .
Could anyone explain what the functionality of each?
What is the difference between match_parent and fill_parent?
They are the same thing (at API Level 8+).
Yes, MATCH_PARENT and FILL_PARENT are just different constants names for the same integer value ( -1 if you're curious) used to specify the layout mode of a View within its parent . >
The fill_parent was renamed to match_parent because the problem with the old name was that it meant to affect the dimensions of parent , while match_parent best described the resulting behavior - corresponding dimension with parent .
What is the function of match_parent?
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 cell phones = > Android 2.2 is advisable to use match_parent , but for compatibility issue for previous versions there is still fill_parent .
NOTE: In versions of the Android API 1.6 to 2.1 it is advisable to use
fill_parentbecause usingmatch_parentin these versions certain errors occur, then in these versions of API usefill_parent.
According to the official documentation of Android itself, it specifies that they are the same thing and that there is no difference in using one or the other.
Basically, none. Both are the same. Documentation link here
fill_parent was renamed to match_parent in API 8 and higher. Try to always use match_parent
In practice, there is no difference.
match_parent replaced fill_parent from API Level 8 .
fill_parent is no longer used, it is deprecated.
It has been replaced by match_parent, you can even use fill_parent , but there may be some "flaws" in the application.
So it's better to use the current same as macth_parent .
