i have referred the following Background Image Placement as in this they need in the bottom corner i need it as background.but anyway with curiosity i tried it but still it is scrolling the background

Answer 1

I tried it and it works. Remove the background from xml layout

getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_ADJUST_RESIZE|WindowManager.LayoutParams.SOFT_INPUT_STATE_ALWAYS_HIDDEN);
getWindow().setBackgroundDrawableResource(R.drawable.login_bg) ;
