using onOffsetsChanged() to get home screen swipe direction

Question

I\'m working on my Live Wallpaper and I want it to scroll with the screen like a normal wallpaper does. I know I need to use onOffsetsChanged() but which parameter will tel

Answer 1

The direction alone will not help you: you need to know the exact offset, because the user may have jumped several screens at once (e.g. by using a pop-up that displays mini-versions of all the home screens).

Generally speaking, you want to save the xPixel value you get in onOffsetsChanged, then use this to translate your canvas.
