• How can I get zoom functionality for images?

  - by Janusz

  Is there a common way to show a big image and enable the user to zoom in and out and pan the image? Until now I found two ways: overwriting ImageView, that seems a little bit too much for such a common problem. using a webview but with less control over the overall layout etc.

• Call AsyncTask methods from another class/service (callbacks?)

  - by TiGer

  Hi, I was wondering if it's possible to call specific methods defined within the AsynTask class from another class and/or service ? In my specific case I have a Service playing some sounds, but the sound is selected from a List with available sounds... When a sounds is selected it is downloaded from my home server, this takes some time (not much, let's say around the 3-4 seconds, the sounds/effects aren't big in size)... So my problem at the moment is that I have a service to play those sounds, and when I select one I wanted to show a progressdialog... The way (if I understood correctly) is to use an AsyncTask, but the only thing the AsyncTask will do is telling my Service to play a specific sound from my server... So there is no "callback" from the service to the Asynctask... How can I achieve that ? How can I call a running AsyncTask, which sits in another class, and tell him all work is done and thus he can stop showing the ProgressDialog ? Or am I over-engineering it and there are other ways ? Thanks in advance...

• Zend Framework-does every webpage have it's own controller and indexAction and view?

  - by Joel

  I'm wanting to be sure that I am setting things up correctly. On a typical website with 10 pages, would each page have it's own controller with it's own IndexAction and it's own View folder with it's own index.phtml as a view? Or do you have one controller with multiple Page1Action, Page2Action, etc and have multiple differently named view.phtml pages within view/index folder? I'm leaning toward the former because then I can have a cleaner controller for each page... Is there a standard, or is it subjective?

• Passing Activity Context to constructors to use internally - is this bad

  - by jax

  Is is bad practice to pass the Context to a constructor and save it as a private variable for internal use? The other option is to pass the Context as a parameter to methods that need it. Which is the better option? I have a feeling that passing to the constructor might result in memory leaks accidentally.

• How to make a scrollable widget?

  - by Sebi

  As far as I have read in the Internet and official documentation, it isn't possible to make a scrollable widget. Also all my tries failed. I even tried to subclass TextView to implement my own scroll method, but nothing worked. Are there any ways to achieve that? Btw.... there are solutions if you use for example htc sense or home desktop ++, but i want to make it available to other users which don't use this

• Minimal example wanted showing texview incrementing a count on a timer?

  - by BobG

  In c it would be: while(1){ i++; printf("%d \r",i); } I assume the textview and the variable and the timer get created in oncreate, then there is a timer handler with an increment and a settext and a sleep? Seeing how to do this in androidese would really clarify things I think. Thanks.

  Sorry if this is too basic. I created a new class that extends Button: public class MyButton extends Button { private Context ctx; public MyButton(Context context) { super(context); ctx = context; } private void click() { // DO WHAT I NEED (FOR EXAMPLE CHANGE BACKGROUND) } } How can make it possible that, when I setOnClickListener() from another class where I instantiated this object, the click() method is called automatically?

• Looking for an approach to program a mobile website for any device. Are there any?

  - by ChrisBenyamin

  My wish is to know how I can program a mobile website, that fit to all mobile phones. Are there any special approaches to recognize a device and render the code according to it? Which tools and coding languages are required? My first thought was to hold the website in XML, which would be parsed depending on the device. You have to consider old phones, even devices with only wap support. For example: The mobile website has to recognize Nokia N75 and render/send the code that looks optimal for this device. Same thing with an iPhone or a Motorola Razr.

• Getting Reference to Calling Activity from AsyncTask (NOT as an inner class)

  - by stormin986

  Is it at all possible, from within an AsyncTask that is NOT an inner class of the calling Activity class, to get a reference to the instance of Activity that initiated execution of the AsyncTask? I am aware of this thread, however it doesn't exactly address how to reference the calling Activity. Some suggest passing a reference to the Activity as a parameter to the AsyncTask constructor, however, it's reported that doing so will always result in a NullPointerException. So, I'm at a loss. My AsyncTask provides robust functionality, and I don't want to have to duplicate it as an inner class in every Activity that wants to use it. There must be an elegant solution.
