if sure memory plenty load required bitmap can load bitmap in background thread before displaying required part of bitmap on visible imageviewer object here sample code off-screen bitmap processing

class bitmapworkertask extends asynctask<integer, void, bitmap> { private final weakreference<imageview> imageviewreference; private int info = 0; public bitmapworkertask(imageview imageview) { // utilize weakreference ensure imageview can garbage collected imageviewreference = new weakreference<imageview>(imageview); } // decode image in background. @override protected bitmap doinbackground(integer... params) { info = params[0]; homecoming decodesampledbitmapfromresource(getresources(), data, 100, 100)); } // 1 time complete, see if imageview still around , set bitmap. @override protected void onpostexecute(bitmap bitmap) { if (imageviewreference != null && bitmap != null) { final imageview imageview = imageviewreference.get(); if (imageview != null) { imageview.setimagebitmap(bitmap); } } } }
