Android :: Spinner Won't Respond To Clicks - Even Though OnItemSelected Is Called?

Jul 22, 2010

My Activity implements OnItemSelected listener for a spinner. It has the interesting problem of firing off the onItemSelected callback when the activity shows. So I used a flag hack to solve it (I hate it, but at this point I just want the app to work).

Strangely enough, even though the callback gets called right at activity start, my actual touch selections don't work. I can touch the list, open it, see the strings from the array adapter, and even touch it to make it dismiss - but the callback is never called.

My code:

CODE:...........

In onCreate():

CODE:..............

The callback:

CODE:................

The toast is shown right when the activity is shown, but when I select items in the spinner, the spinner dismisses and no toast is displayed again (not to mention the rest of the code in the callback fails to execute).

Android :: How To Keep OnItemSelected From Firing Off On A Newly Instantiated Spinner

Apr 1, 2010

I've thought of some less than elegant ways to solve this, but I know I must be missing something.

My onItemSelected fires off immediately without any interaction with the user, and this is undesired behavior. I wish for the UI to wait until the user selects something before it does anything.

I even tried setting up the listener in the onResume, hoping that would help, but it doesn't. How can I stop this from firing off before the user can touch the control?

Android :: How To Catch Fire Of OnItemSelected Of A Spinner After The Interface Has Been Setup

Mar 5, 2010

I am having an Android view with a Spinner on it. I call a populateSpinner() method to add some default values to it.

I also have a onItemSelected() event which gets called before the view is completed to print.
I would like to run a code inside this block only when the user changes the selected items, not when I add or the form gets created.

Nov 24, 2010

I am using a menu in my application Same as this post... I am using a gallery view for display my menu items

Text Gallery on Android?

Problem is that, i implement onItemSelected listener for gallery, so that when new item is selected data related to that topic loaded. But i also want to allow user to scroll the gallery fully. but each time when user move to next item onItemSelected() function called and it start loading data.

All i want to do is to put some delay in onItemSelected() function, so that if in between that delay user scroll next item than there is no need to load data of previous but for the current. Time may be 1 second. If user dose not go for next item in 1 second, that data of that item must be loaded.

I thought to start a thread,but each time for onItemSelected() there will be new thread...

I try this to.

Android : How To Cancel An OnItemSelected Upon Startup?

Aug 5, 2009

1) I have a Spinner with several options provided by an ArrayAdapter and have an onItemSelected listener on this Spinner. When selecting an item from the spinner, I want to display another view (list-view) but this method is unintentionally invoked upon initially displaying the view. The list-view is therefore displayed upon startup of the application. It is possible to add a spinner-on-item-select listener that won't fire upon initially displaying the view but only by the user selecting an item?

Android :: Spinner Widgets Look Different On Different Devices - Can Define Own Spinner That Looks Same On All Handsets

May 20, 2010

I 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, 2010

I 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, 2010

I 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 :: Trapping OnItemSelected Events From An Auto Complete List

Feb 6, 2010

I am trying to write an application with a list of items read in from a file. This item list and the fields that go with each item are fed into a DB. The item names are presented to the user as an auto- completing list. Once the list item is selected, I would like to get the value from the list and use it to query the database and display all the detail information.

The problem I am having is trapping the event using onItemSelectedListener and onItemSelected.

Below is what I am trying.

CODE:..............

This doesn't compile, but it has the fewest syntax errors.

How to get an OnItemSelectedListener to work? and how I grab the value selected?

Android :: Android 1.5 - Asynctask DoInBackground Not Called / Method Called

Oct 26, 2010

I am running into an issue with the way my asynctasks are executed. Here's the problem code:

firstTask = new background().new FirstTask(context);
if(firstTask.execute().get().toString().equals("1"))
secondTask = new background().new SecondTask(context);

What I'm doing here is creating a new asynctask object, assigning it to firstTask and then executing it. I then want to fire off a separate asynctask when the first one is done and making sure it returns a success value (1 in this case). This works perfectly on Android 2.0 and up. However, I am testing with Android 1.5 and problems start popping up. The code above will run the first asynctask but doInBackground() is never called despite onPreExecute() being called. If I am to execute the first task without the get() method, doInBackground() is called and everything works as expected. Except now I do not have a way to determine if the first task completed successfully so that I can tell the second task to execute. Is it safe to assume that this is a bug with asynctask on Android 1.5? Especially since the API says that the get method has been implemented since API 3. Is there any way to fix this? Or another way to determine that the first task has finished?

Android :: On Context Item Selected Does Not Respond

Mar 13, 2010

I am creating a context menu in separate class from the listview, because the contextmenu will be access by several listviews in different classes. Whenever I long-click the listview, contextmenu pops up, but nothing happens when the options were chosen. Tried to look at logcat message and it said something like this:

Window already focused, ignoring focus gain of: com.android.internal.view.IInputMethodClient$Stub$Proxy@43c488f8

Any idea what really causing this problem? cause it works perfectly fine if i put the contextmenu on the same class as listview.

Android :: How To Respond To A Click By Making Imageview Bigger

Nov 9, 2009

I'd like to do something rather simple - I'd like to have an image on the screen and resize it to be bigger when the user clicks on it. I have figured out how to respond to a click by making the imageview bigger (It's a simple call to "setMinimumWidth" and "request Layout"). But that resizes the imageView - not the image in the view... Is there a simple way to do this?

Android : Sync Program Does Not Respond To Mouse Click

Nov 20, 2010

HTC Desire PC Sync issues. PC & Desire connect when Sync initiated from either the phone or desktop icon. PC Sync will display my phone setting and information but it will not sync. The Sync button in Green in the top right hand corner of the Sync program does not respond to mouse click.

Have installed HTC Sync 3.0, uninstalled, reinstalled it - from the HTC website, removed other old mobile applications ie Nokia. I have changed the USB ports etc etc. It has worked once, when I first installed the software and not since then. Also I have USB debugging activated and the phone defaulted connection type: HTC SYNC. Help please as this issue has been active now since I got the Desire 3 weeks ago.

General :: Android Phone Does Not Respond After Ending Call

May 1, 2012

I am using commitva z71 category phone. (motorola quench xt3 xt502).

I had been using cyanogenmod roms on it. presently i have CM 7.1 EAV 7.2. The roms usually came with ADW launcher as default. But one problem I have been facing is that some times my phone does not respond to press of any button, not even power button after ending a call. The screen however goes off and does not light up.

I have to either remove the battery, replace it and restart or I have to make a call to my phone from another phone. When I give a missed call, the phone gets activated. But when I press Menu button, it brings up the keyboard instead of Menu.

This problem has been persisting whichever version of CM Rom I have been using.

The problem aggravates when I use Go Launcher as my default launcher by using Launcher Switcher. When I use ADW as default lanucher but have Go Launcher also on my phone, sometimes the defaults are cleared and I am asked to choose the launcher to finish the task of closing phone app.

Initially, I thought this was the problem of default phone app. So I tried dialer one from play store, but to no avail.

Is there a way to delete the ADW launcher that comes with the custom ROM?

Android :: How To Highlight Clicks In App Widget?

Apr 29, 2010

I have an app widget which runs neatly. However, I am unable to highlight a click on a linked item. I've seen it in the standard app widgets like 'Music' and 'Power Control', for instance. Moreover, I've also been studying the Music app widget's source at album_appwidget.xml. The only thing I could think of is the LinearLayout defined at lines 23-35 which states android:clickable="true".Unfortunately, this does not work for me. So does anyone have a hint on how to highlight a click on an app widget? I've tried the LinearLayout, TextView and Button. None of them displayed a border as a highlight.
