What is the difference between invisible
and gone
for the View visibility status?

From Documentation you can say that
View.GONE This view is invisible, and it doesn't take any space for layout purposes.
View.INVISIBLE This view is invisible, but it still takes up space for layout purposes.
Lets clear the idea with some pictures.
Assume that you have three buttons, like below
Now if you set visibility of Button Two as invisible (View.INVISIBLE
), then the output will be
And when you set visibility of Button Two as gone (View.GONE
) then the output will be
Hope this will clear your doubts.
I'd like to add to the right and successful answers, that if you initialize a view with visibility as View.GONE
, the view could have been not initialized and you will get some random errors.
For example if you initialize a layout as View.GONE
and then you try to start an animation, from my experience I've got my animation working randomly times. Sometimes yes, sometimes no.
So before handling (resizing, move, whatever) a view, you have to init it as View.VISIBLE
or View.INVISIBLE
to render it (draw it) in the screen, and then handle it.
when you make it Gone every time of compilation of program the component gets initialized that means you are removing the component from layout and when you make it invisible the component it will take the same space in the layout but every time you dont need to initialize it.
if you set Visibility=Gone then you have to initialize the component..like
eg Button _mButton = new Button(this);
_mButton = (Button)findViewByid(R.id.mButton);
so it will take more time as compared to Visibility = invisible.
