android - how to fit the whole image on screen as wallpaper -

February 15, 2013

I am developing an app that chooses an image from the gallery and then sets that image as wallpaper but The problem here is that only one part of the image is not a complete image in the form of a wallpaper, but I want to set the whole image as a wallpaper. Can you please tell me how it can be done?

This is my code ...

  The public class extends scaleimage activity first created * / public vs. creature (bundle saved instenstate) {super. Contents (Saved Instantstate); SetContentView (R.layout.main); String filename; File file = new file ("/ sdcard / picture"); File [] imageFiles = file.listFiles (); If (imageFiles.length & gt; 0) {FileName = imageFiles [0] .getName (); Ultimate WallpaperManager WallpaperManager = WallpaperManager.Testense (getBaseContext ()); Bitmap myBitmap = BitmapFactory.decodeFile ("/ sdcard / picture" + "/" + filename); DisplayMetrics displayMetrics = new display metric (); . GetWindowManager () getDefaultDisplay () getMetrics (displayMetrics). Int height = displayMetrics.heightPixels; Int width = displayMetrics.widthPixels & lt; & Lt; 1; MyBitmap = Bitmap.Sant ScalchedBitmap (Merrymatemap, width, height, true); Try {wallpaperManager.setBitmap (myBitmap); } Grip (Exception E) {// TODO Auto generated blocking block e.printStackTrace (); }}}}     
  Set wallpaper size to your image size:  
  WallpaperManager wm = (wallpaper manager) getSystemService (WALLPAPER_SERVICE); Wm.setBitmap (bitmap); Wm.suggestDesiredDimensions (W, H);    Remember to add more permissions:  
  & lt; Usage-permission Android: name = "android.permission.SET_WALLPAPER_HINTS" /> & Lt; Usage-permission Android: name = "android.permission.SET_WALLPAPER" />

apache - How to do an URL rewrite that works with a
pre-existing .htaccess file? -



    I have a platform that is currently available through the URL:    Www.websitecom / index.php? App = forum    Instead, I want people to be able to go here:      & lt; Ifmodule mod_rewrite.c & gt; Option - Multi Views RewriteEngine RewriteBase / RewriteCond on% {REQUEST_FILENAME}! -f Rewrite Convert% {REQUEST_FILENAME}! -d rewriteable /index.php [L] & lt; / IfModule & gt;    It seems that it should be possible, but I'm not sure how to do it.   Thank you!      This has not been tested, but something like that should be done. Add it before the first Rev.Directivity.    RewriteRule ^ forum $ /index.php?app=forums    Alternatively, you redirect from a 301 / forum to index.php URL .   By doing this:    301 / redirect the forum "http://www.website.com/index.php?app = forum    However, it seems that you want to make a proper rewrite, so the first option is better,     






c# - EventSource's response has a MIME type ("text/html") that is
not "text/event-stream" -



    When I try to hook my controller to EventSource, it keeps saying:    EventSource Response contains a MIME type ("text / html") that is not "text / event-stream" canceling connection.    I have created the following class to help in handling a handle and preparing the reaction. In this class I believe that I set the  text / event-stream  according to the response.    public class ServerSentEventResult: ActionResult {public representative string GetContent (); Public GetContent Content {get; Set; } Public int version {get; Set; } Public Override Zero ExecuteResult (Controller Context Reference) {if (context == null) {New argument NullException ("Reference"); } If (this.

Chargset = Faucet; String [] newStrings = context.HttpContext.Request.Headers.GetValues ("last-event-id"...






android - How to build apk without eclipse or Modify the apk building
with a config file? -



    I want to create an APK with some big configurations with an XML file.  I want to know if there is any method which can control the APK's building process or encoding at our source, there is no way to create APK with our source from our source, with a slight variation based on our SQF XML file. . Or any other way to create an APK file    When the app is running, I do not want to read my config file every time, I have to include a change in the application        If you want to manually create your application:    If you are developing in Eclipse, then the ADT plugin The enhanced project as you make changes to the source code. Eclipse automatically produces an .apk file in the project's bin folder, so you do not need to do anything extra to generate .apk.   If you are developing in a non-eclipse environment, then you create your project with the Generated Build.xml Ant file in the project directory that creates ant file calls which automatically targets you for Call the buil...
