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 know I can make 100 different listeners for 100 buttons but I have to think I can create some nifty variables to do it in less lines of code.
In my layout xml file I have set the android:onClick attribute for a Button element to a function in my activity. So when I click the button the function is called with a View as its argument. Are there any information in that View argument that has the id of the button being clicked? I'm trying to figure out if I have to have one onClick function for every element or if I can use one function and switch depending on the id of the element being clicked.
View 1 Replies View RelatedThe layout xml is as below. I have a RelativeLayout, which contains a TextView. The OnClick listener is set on RelativeLayout. The RelativeLayout has a selector background. What I want is, when user clicks on the RelativeLayout, the background of the RelativeLayout should change, and the color of the text of the TextView should change too. Even though I set color selector for the TextView, only the selector on RelativeLayout works. The color selector on TextView doesn't work. How can I implement change of both RelativeLayout background and text color of TextView when user clicks the layout?

View 2 Replies View RelatedI 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 want to run some code when an app is launched, so my broadcast receiver has to be notified when user open any app.

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 wrote a home screen widget with one image on it. When the image is clicked, browser will be opened for a url link.
Generally, it is working. But a weird thing is that, when I click background, then click the picture, the browser will not be open. Until I click the second time on the picture, the browser opens. The steps to reproduce is below:
Click on the home screen widget background.
Click on the image on the home screen. The browser is not opened.
Click on the image again. The browser is opened.
If I didn't click on the background, the image will react to click very well, i.e. browser will be open when the image is clicked the first time.
The widget XML file is as below:

just a short question for a better understanding: I'm developing an app based on the Android 1.5 Framework (with compatibility down to 1.1). But now I read about the new way of implementing click-handlers in Android 1.6 on the Android Developer Blog and I'd really like to use that in my app because it makes developer's life so much easier :) But can I use this (and the 1.6 Framework) without losing backward compatibility to 1.5 and 1.1? Best regards and sorry if this question is dumb [I just didn't find anything via google]

View 1 Replies View RelatedI 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?

View 1 Replies View Relatedi've registered a PhoneStateListener in BOOT_COMPLETED receiver by using following call: tm.listen(new TestCallStateListener(), PhoneStateListener. LISTEN_ CALL _STATE); If the application crashes then system automatically unregisters the PhoneStateListener. Is there any mechanism of checking if particular PhoneStateLister is registered or not? Actually i'm thinking of starting a repeating service by AlarmManager which will check if PhoneStateListener is registered or not . And if it's not registered then service will register it again. Just a backup if application crashes. Is this a good approach or there is some better mechanism to make sure that PhoneStateListener is always registered even if application crashes ?
View 2 Replies View RelatedI have an application that has a tabActivity and 3 tabs. all off the tabs use a location listener and work with locations. i implement onPause and onResume for every tab to remove and start listening for location accordingly. is this the right way to go? i had another idea to work with and that was implementing a location listener to the tabActivity and doing broadcasts to the child tabs with the location, but it seemed more complicated.
The problem with my current solution is that whenever i switch tab i lose the location i got in the previous and i cant use getlastknown location because i dont want the last location on start of the application.(does this make sense?) what can i do to solve this problem. a thing that will work better will be to have one variable that will hold the last location from the onLocationChanged and i can observe its changes and call methods onChange.

View 3 Replies View RelatedI try to create a widget and I am now wondering how to be able to put a button on my widget and set its "onClickListener". It seems that we are limited to the RemoteViews... OK I can deal with that (but this is a limitat to me) but I'd like to add a button where the user can request an update on the data displayed in the widget. (I get some info on the web but the user only needs to request an update, I can't defined an automatique update, it's useless for my app) I'm sure we can do that since there is an example with a player and obviously with a PLAY/PAUSE button. I was looking for in the remoteViews API btu without finding anything.
