Android app to change wallpaper at regular intervals using Timer

由 此生再无相见时 提交于 2019-11-29 04:52:11

Please let me know what should I do? public class Wallpaper extends Service { Timer mytimer; int interval=60000; Drawable drawable; WallpaperManager wpm; int prev=1; @Override public void onCreate() { super.onCreate(); mytimer=new

iOS 7 - Display user wallpaper as UIWindow background

由 只愿长相守 提交于 2019-11-28 22:55:28
问题 How would it be possible to have an iOS app display the user's wallpaper? Apple uses this in places like the tab view in Safari and the keypad in Phone. Setting the transparency of UIWindow proved to no avail... 回答1: This is no longer available.

问题 I'm trying to make an android live wallpaper. I am looking for just a simple example that just displays a solid background and does nothing else to get me started.

Can anyone post the code for just a simple live wallpaper or post a link to an example that definitely works. I've

Changing Wallpaper with a batch file, on program close. Possible? [closed]

由 拥有回忆 提交于 2019-11-28 09:23:41
I'm trying to create a batch file that will change my background when a program closes on Windows 7. I've tried using this, but it doesn't work, even when I log off and log back in: @echo off reg /add HKCU\Control Panel\Desktop\WallPaper /v wallpaper /t REG_SZ /d c:\images\wallpaper.bmp refaim There are some errors in your command: You have added unnecessarry / to add command.

I've created an Android live wallpaper and i'm trying to let a user choose an image from their phone and apply it as a background image, but when I launch the activity that start the intent to pick the images, my shared preferences don't seem to save properly. Below is my onCreate method of the activity I start when the users presses the preference button, and the onActivityResult which gets the path of the image on the device (all that seems to work). The println after I commit the preferences prints out nothing. @Override public void onCreate(Bundle savedInstanceState) { super.onCreate
