Android Live Wallpapers — OpenGL vs Canvas

由 筅森魡賤 提交于 2019-11-27 12:25:31
问题 I am a fairly "newb" Android developer, and I would like one of my first projects to be a live wallpaper, however I am conflicted on whether I should be focusing on Canvas or OpenGL for it. Being new to this I know I should master Canvas first since it is easier to use, but I prefer to learn from real world projects that I have an interest in, even if it's a little backwards at times. I have used both before in very basic ways, and I understand the general concepts to them, but I am not sure

I am learning how to make live wallpapers, but I have a dilemma I'm sure all who start off have as well. There is so many resolution screen sizes, how can I just make one set of artwork to be rescaled in code for all versions? I know it's been done as I seen the images in the apk's on a lot of them and they get rescaled. If it was just one image that did not need any positioning that would be easy, but my problem is I have to get the background image rescaled to fit all devices, I also have animations that fit in a certain x and y position on that background image to fit in place so it looks

Android Live Wallpaper Touch Event Hierarchy

由 落爺英雄遲暮 提交于 2019-11-26 23:31:52
问题 I have a Live Wallpaper that uses various screen touches to trigger certain events. At the moment it is working but I seem to get all touch events. For example, when the user touches an icon to launch an app, I seem to get that event too. Is it possible to determine whether the user has touched the background screen (i.e. the inter-icon gaps.) so that I can only take my actions at that time and ignore the others. Failing that, (and assuming – possibly erroneously – that if I am first in the

using onOffsetsChanged() to get home screen swipe direction

由 ▼魔方 西西 提交于 2019-11-26 21:44:20
问题 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 tell me the direction that the home screen is being swiped? It seems like xOffset always returns a positive value no matter which way the screen slides. Thank you. 回答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

Choosing background for Live Wallpaper

由 穿精又带淫゛_ 提交于 2019-11-26 19:21:24
问题 I'm writing a live wallpaper that creates an effect over a background. I want the user to be able to choose the background from any of the system wallpapers and camera photos. What I would like is for the user to be able to press a button in the Settings menu, have the list of options show up just like setting the wallpaper from the home screen, minus the Live Wallpapers options. Once the user navigates the choices and picks an actually image I would load it to my canvas. How do I do this? I
