Set layout background to parts of a large image in Android -


i trying generate view pager swipe layout, instead of set of images, want use 1 enlarged image. when users swipes, layout should display portions of images single image.

to acheived view

i know how use view pager show different images. need above ui spec.

[edited] don't want implement viewpager anymore. have big image shown above. want display parts of image on event. example there 5 actions, , want divide image 5 parts , display based on action choosen dynamically. used bitmap files recreate part of image large image has low performance. (ui gets freezed). although create 5 different bitmaps before activity loaded, setting bitmaps background when user performs event freezes ui. please let me know if there alternate way show parts of image without using bitmap
