Android :: Spinner Widgets Look Different On Different Devices - Can Define Own Spinner That Looks Same On All Handsets
May 20, 2010I use this code to generate a spinner in my app:
code:.........
On my device (Motorola Milestone) and in the emulator this looks like the standard gray spinner widget.
On of my colleagues uses a Motorola Backflip and on his device the Spinner is black. Now its very hard to read the font in the spinner.
What do I have to do to use my own view for the spinner? I don't mind to have the gray spinner on all devices, but it should always look the same on all devices.

Android :: Call Spinner's Value - Use Other Values Based On A Spinner's Value
Jan 25, 2010I have a spinner 'aperture' set up with a list of numbers, and a spinner 'mode' with two options. When a button is pushed I need a calculation to run using various inputs, including the current selection from 'aperture' and a value derived from 'mode'. How do I call the value of a spinner so I can use it in a calculation?
Also, how do I use the spinner 'mode's selection to set this other value before implimenting it in the calculation? To be more specific, if the spinner is set to Small then the value I use in the calculation is 0.015, whereas if Large is selected I need to use 0.028
My other inputs are EditText views, so right now I am set up like this:
CODE:............
That is not the actual equation, it is just a test to make sure everything connects properly. How would I call the value of spinner 'aperture' and the Small/Large spinner 'mode'
Android :: Popup List Like Spinner Without Spinner
Jan 25, 2010I have a spinner widget in my activity which lets users pick a list name.
Normally, the function of the spinner is to switch between lists but for a couple of instances, I swap out the selection change listener to perform a different function with the same list of options. Once the selection has been made, the old listener is restored and life goes on.
This is a bad and buggy arrangement. Instead, I would like to have a function that just takes a selection listener and some other parameters and shows a popup list that's populated by the same cursor (or and identical cursor) as the spinner, without using the spinner itself.
Is there any way I can do this?
Android :: Populating A Spinner From Another Spinner Dynamically

View 1 Replies View RelatedAndroid :: Any Listener For When WebView Displays Content?
Oct 31, 2010Using WebViewClient and/or the WebChromeClient you can get a listener for when the page has loaded, however this is sometimes called before the WebView has any content in it, before it has displayed anything. What would be a efficient method for determining when the WebView has displayed it's content? When I load a page in a WebView, I want to set the scroll to a specific position. It seems that the scroll position cannot be set until the page is loaded and it has an actual content height. So, I have tried two different approaches to determining when the page has finished loading, onPageFinished() from the WebViewClient and also onProgressChanged() from the WebChromeClient.
Both of these tell me when the page has finished loading. However, the problem is that sometimes it is called before the page has been displayed and therefore the page has no height and the scroll call does nothing. I am trying to find a solid way to determine when the page is ready to be scrolled, i.e. when it has its content height. I imagine I could setup a checking loop after it finished loading to keep looking for when the height is available but that seemed like quite the hack. Hoping there is a cleaner way.

Android :: How To Unregister Listener After Application Get Closed
Apr 28, 2010I am writing an application that listens to phone calls and perform some tasks when phone call arrives. The Application contains one activity which includes 2 buttons 'Start' and 'Stop' (where starts register the listener and stops unregister it - see code below).
The problem starts when the application is closed ( onDestroy is called ). If the user pressed on the start button and exit from the application the listener still working (which is the expected behavior) but from now it is impossible to unregister the listener since launching new instance of the application create new instance of phoneListener.
My question is:
1.Is there better way to implement my requirement?
2.Can I save the phoneListener object and reload It on application creation?

Android : Listener - Back Button - And OnDestroy
Mar 13, 2010I have an application with a single Activity implemented as a singleton (in the AndroidManifest). It implements a Listener I wrote. When the application is first run the Listener works fine. When I use the "home" button to minimize it, then open it again it's still fine.
But when I press the back button then run it again from the application icon, the Listener doesn't work fully. The code runs and the Listening methods are called as usual but none of the UI elements that are listening update. It requires a restart of the phone to get the listener working again after this point.
I know the "back" button doesn't really close the application, per se. But resetting the phone sure does! Is there a way to use the onDestroy() or similar method to call a function that actually closes the application? I'm asking because restarting the phone is the only way to get the listener back so I was hoping I could do that programmatic ally.
For example, my progress bar is a member variable of my Activity, but onCreate() I do "progressBar = (ProgressBar) findViewById(R.id.progress_bar);" Is this perhaps creating a separate instance of it or something?
