[android-developers] Re: Is Zoom in And Zoom out is Possible for Image View In android............
Hi there! I had to write a duplicate of the image viewer last week. And I couldn't find the Image View source code. For those wondering why I didn't use the intents, it's just because my images are dynamically loaded from the web... Since I did it for my company, I can't publish the source code. But I can give you some tips. First of all, you should read this: http://groups.google.com/group/android-developers/browse_thread/thread/13fafedb71ccc296/0c0bc0830a20ee82 The whole tip is about using an ImageView with a Matrix. The Matrix enables you to translate / scale / rotate the image, so basically, zooming is just a question of scale + translate (to zoom to the center: when you scale, the fix point is the top left corner, so you need some translates so that the center is the fix point). Good luck with that.

[android-developers] Re: Automated Functional Testing
Err... nice ! But, this is an Android mailing list. Writing such a long text in the wrong place, I feel sorry for you ;-) . On Jul 9, 7:59 am, Software Testing Training qacampu...@gmail.com wrote: Automated Functional Testing By Bhrigu Malhotra (http://www.qacampus.com) First of all let me make you all aware that I’m a developer and what you are going to read further is a developer’s account, so it may sound to you like a layman tester. But what I’m going to share is something which has been very helpful to me to ‘functionally’ test the web application our team has been building and I thought this may help you as well. So even if you are a tester, try to think the way developer’s think for some time, I’m sure this would be useful to you too. Before I go ahead, I think we all understand that Functional Testing is testing the functionality of our application which means you’d probably be going through a login using some credentials, clicking some links, verifying some outputs - in simplest terms. Now just give it a thought that if you can automate these i.e. invest some time for once and then while you are sipping a cup of coffee, someone is testing what you coded. Change your code 10 times and run your test 10 times to ensure nothing breaks, so easy. Not just this if you have continuous integration server setup which runs your tests, you’d come to know immediately if and when someone else broke your code. Believe me ones who have used it, feel it is fantastic. There are a variety of tools available for this over internet each with pros/cons but I’m going to share some info here about one which I liked very much and have been using for a while now. I’d also share why I preferred it over others. Ok, no longer prolonging the suspense the tool I’m talking about is called Canoo WebTest (webtest.canoo.com) which is a free Open Source tool for automated testing of web applications in a very effective way. The primary reason why I liked it is that it is FAST; very fast … most of the test cases that I’ve written are executed in less than a minute and that too over remote applications deployed on servers on the other side of globe. Second reason for liking it so much is the ease of writing; very quickly you can build up your tests. Though they have released a WebTest recorder plug-in which when installed in Mozilla Firefox can record the script for you, but believe me the more you start writing there test cases, the less reliant you will become on the recorder. Third thing is these tests do not use a browser so that completely eliminated browser-specific issues which some tools are plagued with. Now some things about WebTest which some people don’t like is you actually do not see the tests being executed i.e. loading of a browser window, automatic clicking on buttons and errors on the screen (if any). But that I feel that it is so by design …. Doing all this takes time and then browser issues too creep in, so I’m happy like this way only. I agree they can improve on reporting of errors but again the objective of this tool is to test and just to test, if you want to report issues manual intervention is needed. At last I’ll just say go give it a try, I’m sure once past initial hiccups, you’ll start liking it the way I am. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Re: Canvas Scaling issues
Hi !
Thanks for the link, the GestureDetector is nice. I started working on
this today, and found another way to zoom move, which I think may
be simpler.
All you need is to set a specific Matrix on an ImageView. The matrix
will apply transformations on the image (here we just want to scale
and translate).
In your layout, just put an ImageView:
ImageView
android:id=@+id/zoom_test
android:adjustViewBounds=false
android:cropToPadding=false
android:scaleType=matrix
android:src=@drawable/some_drawable
android:layout_width=fill_parent
android:layout_height=fill_parent
/
In your activity code:
ImageView zoomTest = (ImageView) findViewById(R.id.zoom_test);
Matrix mtrx = new Matrix();
mtrx.postScale(1.5f, 1.5f);
mtrx.postTranslate(-120f, -120f);
zoomTest.setImageMatrix(mtrx);
zoomTest.invalidate();
I still need to find the appropriate values, and let the user
manipulate the GestureDetector and press the zoom button, but I think
I will go that way.
I found this solution by reading ImageView source code, and reading
this:
http://groups.google.com/group/android-developers/browse_thread/thread/bdc4998a70f310c7
More on this topic when I'll have done the whole stuff.

Hey folks,
A few weeks ago I posted a view I was working on and in that time I
have improved the view a lot, but I've been asked to add a new
features of zooming into the image.
The view is a custom image viewer that allows large images (such as
640x1000) to be loaded, and the user to scroll around using either the
touchscreen or trackball on the device. The code below is reasonably
succesful in that it works at the default scale level of 1.
But with addign zooming, instead of zooming into the 'centre' of the
location the user is looking at, and allowing the user to move around
the whole of the image at this level it instead zooms into the top and
left of the location, and in doing so it starts to cut off the bottom
and right of the image whole, so while zoomed in you cannot go any
ruther right or down in the image, but you can go to the top and left
easily enough.
The best example of what I am trying to achive is the Image viewer in
the camera application.
So my two questions are:
1) Can anyone suggest how I can fix this in the canvas or
2) Is there a better way to do this with an existing feature in the
framework?
I'm probably thinking it's something to do with the modifierValue when
scrolling around that I somehow need to increase this, but trying this
causes my activity to crash.
Code:

Hello, Have you read the MapView tutorial ? It shows how to display multiple items on a map: http://developer.android.com/guide/tutorials/views/hello-mapview.html In this example, you should notice the following lines of code : ListOverlay mapOverlays = mapView.getOverlays(); mapOverlays.add(itemizedoverlay); If you want more overlays (such as another overlay for location), then you just need to add it to the list ;-) . The adding order is important, because it directly impacts the drawing order and the event handling order (clicks..)

[android-developers] Android apps + Dependency Injection = try out Yasdic!
Hello developers, I have been using the Android SDK for a few months now, and one thing I was missing was a dependency injection container. Dependency injection is a good practice to lower the coupling between the components of your application. I thought about using Spring, or PicoContainer but they use the reflection API to provide dependency injection. And the reflection API may not be the best speed partner for your Android apps. I couldn't find any real small dependency injection container, that would provide dependency injection without reflection. Here comes Yasdic, Yet Another Small Dependency Injection Container, no more then 6.7KB. The definitions are written programmatically and stored by String ids, the beans are lazily created, and Yasdic also deals with singleton and prototype scopes, cyclic dependency, and container hierarchy. Please feel free to try it out : http://code.google.com/p/yasdic I already use it in my Android apps, and I find my code to be much more maintainable (thought this is a quite subjective point of view ;-) ). Any feedback on this project will be appreciated, even code criticism :-) . Regards and thanks !

[android-developers] Re: Android apps + Dependency Injection = try out Yasdic!
Hello, Thanks for this quick answer. I do not pretend to compete with Guice, but let's try to answer your question: Google Guice provides a reflection oriented dependency injection container. The AOP version provides fast reflection using cglib, but this version cannot be used with Android (source: http://code.google.com/p/google-guice/wiki/OptionalAOP). So using Guice in Android, we are stuck with slow reflection. And Guice uses a lot of reflection. Furthermore, Guice provides a type oriented injection, whereas Yasdic provides an id oriented injection. Which one is better ? I guess it's up to you. You are free to have a look at the Android example here: http://code.google.com/p/yasdic/source/browse/#svn/trunk/examples/countadroid I think Yasdic is much simpler and much faster to learn than Guice, but it requires a bit more writing. Beans are defined in a programmatic style, writing code in anonymous classes. This allows you to do anything when initializing beans, even complex computations involving multiple beans. Maybe I should make some speed / memory tests, to see what's the real difference. Any suggestion about this will be welcome, to prevent me from writing an unfair test ;-) .

Please feel free to try it out :http://code.google.com/p/yasdic I already use it in my Android apps, and I find my code to be much more maintainable (thought this is a quite subjective point of view ;-) ). Any feedback on this project will be appreciated, even code criticism :-) . Regards and thanks !
