Android Wheel Widget

essay writing service sydney

Buy Adobe Photoshop CS3 Extended: Retouching Motion Pictures This is a simple widget I created as part of the Aviary Editor SDK for Android. It creates a wheel-like widet which can be scrolled in both directions.
The idea was to replace the default slider widget and use a more “real world” component.
Moreover if you’ll add the VIBRATE permission into your AndroidManifest.xml file you’ll have also haptics feedback while the wheel is scrolling:

1
<uses-permission android:name="android.permission.VIBRATE" />

http://www.catcoglobal.com/?college-essay-how-to To include the wheel widget in the current layout, you should add in the layout xml this lines:

<it.sephiroth.android.wheel.view.Wheel
android:id="@+id/wheel"
xmlns:sephiroth="http://schemas.android.com/apk/res/it.sephiroth.android.wheel"
android:layout_width="match_parent"
android:layout_height="match_parent"
sephiroth:numRotations="6"

Android Workspace Widget

blank  

next I was looking for an android widget similar to the launcher workspace widget ( the one used in almost all launchers ), but a bit more customizable and with the possibility to use an Adapter as content provider. So at the end I mixed portion of code from the android launcher Workspace widget, the Gallery widget and the AbsListView widget.

http://albaniaturismo.com/?p=writing-term-paper-proposal Nothing particular tricky, just a combination of the 3 widgets in order to have the same sliding effect of the workspace ( using custom number of columns and rows ), but at the same time with an http://atakkumas.com.tr/college-essays-where-can-i-have-someone-write-it-for-me/ college essays where can i have someone write it for me ArrayAdapter for creating views, and a little glow effect at start at the end of scrolling for creating the gingerbread style overscroll effect.

Compile skia for android on Mac Lion

here Some time ago I started to look at skia as possible solution for graphics 2D editing for a native android project I was developing.
Well, even if skia is part of the android system and it’s used everywhere by android itself, trying to include skia in my project was quite an hell..
Looking for resources I just found old examples and tips, and every try was just a failure.. but since android uses skia internally to do graphics operations I decided to look into the android project.

http://lubeofsarasota.com/selling-gold-do-your-homework-first/ selling gold do your homework first After downloading the skia module from the android git repository I just realized it couldn’t be compiled by itself because it has external dependencies. So next step was to download and compile the whole android source code. Easy task? not at all, at least if you’re on a mac running Lion!

blank At the end I managed to compile everything and build the skia module as static module, in this way now my project can link the skia library and include correctly the skia headers.

source link Ok, I don’t have the whole procedure step by step here, first of all because it depends on the android version you’re going to compiled, second and most important because I didn’t write down all the steps 🙂 So this is more a sort of list of notes about compiling android on Lion and a reminder for myself too. ( I was trying to compile android 2.2 using “generic-user” as lunch configuration )

Build Android: http://source.android.com/source/initializing.html

Java 1.5 version complaining: http://wiki.oneswarm.org/index.php/OS_X_10.6_Snow_Leopard

Well, the first time you’ll try to “ tire recycling business plan make” everything probably you’ll get this error:

./external/elfutils/config-compat-darwin.h:42: error: static declaration of ‘strnlen’ follows non-static declaration

return len;
}

{
int len = 0;
while (__maxlen-- && *__string++)
len++;
return len;
}
#endif

Well, at the end of the process I just edited the Android.mk makefile into external/skia adding a new entry for BUILD_STATIC_LIBRARY and the next command was simply:

1
mmm external/skia

which produced the required libskia.a file to be linked in my project.

QuickActionView in Android

While I was searching for an custom implementation of the QuickContactBadge for Android, I went into this interesting post ( Phd Thesis Written Lorenz’s Blog ), which had a custom widget called custom written literature review QuickAction.
While it’s a very nice widget, it didn’t fit my needs because I had the necessity of create different action layouts ( horizontal, vertical, grid.. ), so I made a very quick modification to the above code and I ended with this implementation.
Basically I removed from the original Class the ActionItem list and set a http://www.pedijatrija.org/?financial-plan-of-business-plan financial plan of business plan BaseAdapter as content source. In this way it’s more simple and easy to add more and different views to the widget.
Moreover I added the support for columns ( both fixed and automatic ).

   // set the adapter
   qa.setAdapter( new CustomAdapter( this ) );
     
   // set the number of columns ( setting -1 for auto )
   qa.setNumColumns( (int) (2 + (Math.random() * 10)) );
   qa.setOnClickListener( new DialogInterface.OnClickListener() {

      @Override
      public void onClick( DialogInterface dialog, int which ) {
         dialog.dismiss();
         Toast.makeText( getBaseContext(), "Selected item: " + which, Toast.LENGTH_SHORT ).show();
      }
   } );
     
   // finally show the view
   qa.show();

FBTracer updated to Firefox 5

FBTracer in action

paper for sale FBTracer aka Flash Tracer has been just updated to version 0.1.3 ( also thanks to Daniel D. Vanzin ) which is now compatible with the new Firefox 5.

If you already have the extension installed it’s just a matter of check updates from the addons firefox page, otherwise you can download the extension from this page: http://blog.sephiroth.it/firefox-extensions/flash-tracer-for-firebug/

Note. After a fresh install or update of the plugin, sometimes the fbtracer panel doesn’t refresh itself… in that case a firefox restart will fix the problem.

ImageView Zoom and Scroll

buddhism essay Update: the source code has moved to github, so it’s easier for anyone to fork it!

As long as Android doesn’t have a built-in ImageView widget with zoom and scroll capabilities I tries to create one by myself starting from the google repository.

The result is pretty nice so I’m posting here the source code, if anyone is interested, or simply doesn’t want to waste the time creating a new one.

Here’s a sample code on how to use it in an Activity:

Widget: SlidingDrawer top to bottom

My android experiments continue…
In the last project I had to implement a SlidingDrawer which comes from top and left. The problem was that the default widget does not support all the directions, but only bottom to top and right to left.

That’s why I grabbed the SlidingDrawer source code and modified it in order to allow any direction ( defined as styleable in attrs.xml ). The only problem using custom styleable xml is that if you want to use this widget as library you need to include in the main project also the attrs.xml file as well.. a bit frustrating.

Anyway this is just the sample xml how to include the widget:
