i get a position of the view and then define a field

 private int mPos = 0;

then check the

 if (mPos < galleryimages.length - 1)
     ++mPos;
     galleryview.setSelection(mPos, true);

this is for right arrow(>) and for left arrow(<) is

 if (mPos > 0)
     --mPos;
     galleryview.setSelection(mPos, true);

This is the answer and also it is working.
