Android : Want To Make A Listener For A Datepickers Cancel Button In Droid?
Jun 26, 2010
I'm using a datepicker in Android to let the user to choose the date. I want it to do one thing if the user picks a date and sets it (I have that working fine) and then to clear a certain text field if the user pushes the cancel button on the datepicker (open up the datepicker but then cancel out of it).
The way I've been trying is by making a code...
to attach the listener.
My problem is that the listener works if the user pushes the back button, but not if they push the cancel button. I tried using a dismiss listener, and that works, except for the fact that it goes off even whether I set or cancel the datepicker!
What do I need to do so something goes off if and only if I push the cancel button on my datepicker?

I'm facing the same head-scratching moment similar to what this person (from Jan 2008) experienced when I realize that there is no cancel button in Android's progress dialog or spinners. It is now July 2009 and I've just installed the cupcake version of Android. Has this thing changed ? If not, are you adding a cancel button into the dialogs and how do you do it ?

In my application pressing a list row or a button means executing the same commands. My problem is that the list and the button have different listeners (AdapterView.OnItemClickListener vs. View.OnClickListener). How can I add the code for the 2 views (as a listener) without having duplicate code.

I 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?

I'm creating my first widget and ran into a snag. I have several buttons on this widget and need a way to register an onClick action for each of the buttons. So far I've only found examples where they start a configuration activity from a widget button. Does someone have example code on using buttons in home screen widgets?

I have a listView, where each row has a button in the row layout. However, this seems to make the row itself unclickable. How can I make both the button and row clickable?

I tried the market and searched google (only to find apps that help you sleep lol). I'm looking for a way to set a button on the home screen to press and put the phone to sleep instead of having to push the top button all the time.

This would fix my only complaint about the phone! It's quite annoying when I'm in a call and doing something else on the phone, and I lose the soft end call button and can't hang up.

Mine feels a little loose, and it make a rattle sound, am i the only one with this? its like the plastic isnt tight or something, but when you press it its nice and firm to "click" up or down.
also the bottom of the screen/whole left side where the KB is kind of dips down about a hundreth or tenth of an inch wen you press something on the screen on that side, im guessing thats normal for a slider.

I wrote some code that mute the phone whenever an incoming call is received.
When the phone in vibrate mode I use the following code to stop the phone vibration:
Vibrator vib = (Vibrator) context.getSystemService(Context.VIBRATOR_SERVICE);
vib.cancel();
While it worked on my Nexus One with android 2.1, it seems that it doesn't stop the vibration on an HTC Desire handset with android 2.1.
Have someone encountered this issue?

I need to set up a simple event listener to refresh a listview from once in a while. The problem is I don't know how could I generate an event.
I know that for events like key or button pressing I just need to implement the handler. But in this specific case I actually need to generate the event, which will be fired everytime another running thread of my app wakes up and refreshes it's list of news from a rss feed.
I've done everything, but got stucked in here. Can I get any suggestion or link with some more info on how to implement this?

I'd like to know how to make a button out of a PNG and display it on my canvas (using drawBitmap?). When I click on this button, it will take me to a new activity. All this will be in the onClickListener. So, how do I take a PNG, make a button with it, and draw it on my canvas? I looked at ImageButton, but I'm unsure how it works or how to draw it on the canvas.

Is it possible to register a listener to listen for changes in the volume level of the music stream in Android?
I'm displaying the actual volume in a SeekBar and I would like to change the seekbar if the user changes the volume with the hardware volume keys. At the moment the correct volume is displayed until the user changes the volume with hardware keys.

I have an android app that listens for json commands over a socket. I am wondering how I can implement this as a background service. The service would receive the commands and depending on which commands they are, notify the user, or update data within the main program. Some code examples would be great if anyone has them. I've got an example of how to build a background service however it uses timers. I'd like for socket to always be listening.

I placed my DINC order Monday and was completely content until my coworker just walked in w/ his Droid X this morning. My biggest qualm beforehand was the size, but now that I hold it in my hands it's not so bad.I've never had an Android device but everyone tells me HTC Sense will blow me away. I need you all to convince me that the X will blow me away (if you do I'll swing by after work and cancel the DINC order and grab a Droid X). I'm not worried about specs and stuff, just user interface. What can I expect to get with the X?

Is there an app or widget that can be used to make a larger button? I'd prefer a 2x2 size that I can use to direct dial while driving rather than having to fiddle with the small 1x1 size, but anything bigger than the standard would be fine.
I've only found apps that make smaller buttons and one that makes me select subsequent options before I can actually call. I just want a large single press widget.

I have a simple Android app that does some math on 2 numbers that the user inputs and returns the result.
Currently I have a 'calculate' button that needs to be pressed to do the math and return the value.
How can I get rid of this button and just get the app to run the math after the uses has changed either one of the 2 numbers?
