To me fill parent and match parent performs the same function only that   fill parent  Was used before API 8  match parent This was used from API 8  Function of Both Fills the parent view aside the padding

Google changed the name to avoid confusion   Problem with the old name fill parent was that it implies its affecting the dimensions of the parent  while match parent better describes the resulting behavior - match the dimension with the parent   Both constants resolve to -1 in the end  and so result in the identical behavior in the app   Ironically enough  this name change made to clarify things seems to have added confusion rather than eliminating it

FILL PARENT was renamed MATCH PARENT in API Level 8 and higher which means that the view wants to be as big as its parent  minus padding  - Google

User · Answer

Just to give it a name closer to it s actual action   fill parent  does not fill the remaining space as the name would imply  for that you use the weight attribute   Instead  it takes up as much space as its layout parent  That s why the new name is  match parent

match parent  which means that the view wants to be as big as its parent  minus padding    wrap content  which means that the view wants to be just big enough to enclose its content  plus padding   For sake of better illustration  I have created a sample layout that demonstrate this concept  To see it s effect  I added a border of each textView content   In  Match parent  textView content  we can see it s layout width spread out of it s parent whole length   But we can see in  Wrap Content  textView content  it s layout width wrapped in of it s content Wrap Content  length

1  match parent  When you set layout width and height as match parent  it will occupy the complete area that the parent view has  i e  it will be as big as the parent    Note   If parent is applied a padding then that space would not be included    When we create a layout xml by default we have RelativeLayout as default parent View with android layout width  match parent  and android layout height  match parent  i e it occupies the complete width and height of the mobile screen    Also note that padding is applied to all sides    android paddingBottom   dimen activity vertical margin  android paddingLeft   dimen activity horizontal margin  android paddingRight   dimen activity horizontal margin  android paddingTop   dimen activity vertical margin    Now lets add a sub-view LinearLayout and sets its layout width  match parent  and layout height  match parent   the graphical view would display something like this    match parent example   Code  xmlns tools  http   schemas android com tools  android layout width  match parent  android layout height  match parent  android paddingBottom   dimen activity vertical margin  android paddingLeft   dimen activity horizontal margin  android paddingRight   dimen activity horizontal margin  android paddingTop   dimen activity vertical margin  tools context  com code2care android togglebuttonexample MainActivity   gt   android layout width  match parent  android layout height  match parent  android layout alignParentLeft  true  android layout alignParentTop  true  android layout marginLeft  11dp  android background   FFFFEE  android orientation  vertical   gt    2  fill parent    This is same as match parent  fill parent was depreciated in API level 8  So if you are using API level 8 or above you must avoid using fill parent   Lets follow the same steps as we did for match parent  just instead use fill parent everywhere    You would see that there is no difference in behaviour in both fill parent and match parent

Functionally no difference  Google just changed the name from fill parent to match parent  from API level 8  Android 2 2   FILL PARENT is still available for compatibility reason   LayoutParams FILL PARENT and LayoutParams MATCH PARENT both have value -1  Not sure what tempted google to change from Fill Parent to Match Parent     Since most of the phones are  gt   Android 2 2    you should use Match Parent for future compatibility    not sure when they will discontinue the older Fill Parent constant

User · Answer

For compatibility sake it s better to stick to fill parent  i e  when supporting below API 8 devices  But if your app targets API 8 and upwards  you should use match parent instead
