After the view has been created? What have you tried? – Gettysburg

Answer 1

centre of the imageView will be

 centreX=imageView.getX() + imageView.getWidth()  / 2;
 centreY=imageView.getY() + imageView.getHeight() / 2;

but make sure you call it after the imageView created

Seems getX() and getY() can not be used when api level below 11 – Badalona

What if the imageView is scaled ? – Wordbook

this solution is only relative to parent view. If you want it to be global you should use the getLocationOnScreen or getLocationInWindow methods – Charismatic

centreX and centreY will be float – Lakh

Answer 2

You can use getPivotX() and getPivotY(), it always keep in center of view even rotate view.

Answer 3

Try this :

ImageView my_image = (ImageView) findViewById(R.id.my_imageView);  

Rect rectf = new Rect();
my_image.getLocalVisibleRect(rectf);

Log.d("WIDTH        :",String.valueOf(rectf.width()));
Log.d("HEIGHT       :",String.valueOf(rectf.height()));
Log.d("left         :",String.valueOf(rectf.left));
Log.d("right        :",String.valueOf(rectf.right));
Log.d("top          :",String.valueOf(rectf.top));
Log.d("bottom       :",String.valueOf(rectf.bottom));

Hope this helps you.

Answer 4

As @aiueoH mentioned, you can use getPivotX() and getPivotY().

Try using this for finding coordinates of centre:

int centreX = view.getPivotX()/2;
int centreY = view.getPivotY()/2;

Perhaps divide by 2 is unneeded? The documentation states "If no pivot has been set then the pivot will be the center of the view." – Thorne

Answer 5

if you wish to align a view at the center of other view then you can use this -

float center_x = parent_view.getX() + parent_view.getWidth()/2 - child_view.getWidth()/2;

and then obviously using -

child_view.setX(center_x);
