Hi,
I am getting starange issue on surfaceview but when used view it
worked fine.
1.) when using view and drawing image using
canvas.drawBitmap(mBitmap[CntcurrentImage], 0, 0, null); works
perfectly and draws image fully fitting in the screen.
2.) But when using surfaceview and doing the same thing is streching
the image(not fully fit in the screen).
I am not getting any clue on the issue.
below is the code:
