Android :: Registering OnClick Listener On Application Widget Button

May 15, 2010

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?

Android : Listener - Back Button - And OnDestroy

Mar 13, 2010

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?

Android :: Variable OnClick Listener ?

Jun 25, 2010

Is there a way to have 1 onClick Lister for many buttons where I can toss a case statement to do things based on what buttons were clicked.

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.

Android :: OnClick Listener One Function For All Clicks

Nov 14, 2010

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.

Android :: Implement Color Selector Of TextView When The OnClick Listener Is Set On Its Parent Layout?

Aug 8, 2010

The 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?

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?

Motorola Droid X : Back Button Functionality - Cannot Simply Go Back One Menu Using The Back Key

Jul 15, 2010

This is my first android device and i'm loving it... but one thing that irks me is the use, or lack thereof, of the back button.

As I am navigating menus and options in the Settings, I cannot simply go back one menu using the back key. For example, if I go to Settings->Battery Manager->Battery Profile Options and want to go back to the Settings screen, I cannot.

Pushing the back button does nothing and I can only go back to the Settings menu by going Home, then re-entering.

Another quirk regarding the back button is when reading emails. Using a regular email account such as Hotmail, I cannot simply read an email and go back to the inbox using the button.

It makes navigating the phone very tedious.

Android :: Trying To Open New Image On Clicking A Image Button

Android :: How To Control Activity Flow - Back Button Versus Home Button

Sep 2, 2010

I have 3 activities in my app: Activity1 -> Activity2 -> Activity3. Inside Activity3, if the user presses Back, I would like to return to Activity2. In Activity3's onPause event, I added a finish() statement. That's probably not even necessary, but I wanted to make sure this Activity gets cleaned up. This works fine.
However, while in Activity3, if the user presses Home or starts a new app (through notification bar or some other means), I want both Activity3 and Activity2 to finish. If the user returns to this app, he should resume with Activity1.

I have figured out how to do one or the other, but I can't figure out how to handle both cases, if it's even possible. Can I trap the "Back" button in Activity3 and send a message back to Activity2 telling it not to finish()? It seems like the Activities follow the same lifecycle flow (Pause, Stop) regardless of what you do to send them to the background. Just to answer the question of why I want this behavior, imagine that Activity1 is a login screen, Activity2 is a selection screen, and Activity3 is a content screen. If I press Back from the content page, I want to be able to make a new selection. If I exit via any other means (Home, notification bar), I want the user to be "logged out".

Android :: WebView.clearHistory() - Don't Want Back Button To Allow User To Go Back Further Than Current Session

I call WebView.clearHistory(), but I am still able to go back after doing so. I want to reuse a WebView, but I don't want the back button to allow the user to go back further than the current "session" of using the WebView. Anybody know what is the best way to handle this? I thought for sure that clearHistory() would do it.

Android : Back Button - Disable In Buffering Or Should Prevent The Player Tostart If Back Is Clicked

Oct 11, 2010

In my android application i have a video list screen,a buffering screen and a videoplayer screen.
As soon as the user clicks an item from videolist screen ,he is navigated to buffering screen and then to videoplayer.
In the buffering screen i am using Async task and doing the loading process in on background process.

Now my issue is like the user if has selested a video then gets navigated to buffering screen.But if the user clicks back when he is in buffering screen then initially he is getting navigated to videolist screen but immediately after that again he is navigated to videoplayer screen.

What i would like to have is either the back button should be made disable in buffering or should prevent the player tostart if back is clicked.

Motorola Droid X : Back Button - Swipe Left To Right On Maybe The Top Bar It Goes Back

Jul 19, 2010

I'm finding that I'm using the back button A LOT whether browsing the web or just navigating the OS. It kind of sucks because the buttons on the droid x are well, really small, and sometimes hard to press because they are so narrow and flimsy feeling. And depending on how you are holding the phone, it could be a good bit of distance for your thumb to travel or I'm finding myself having to reposition the phone in my hands just to reach the back button, which you seem to need very frequently.

Anyone know of any kind of back 'swipe' implementation ? Like some software you can install that makes it if you swipe left to right on maybe the top bar it goes back?

HTC Incredible :: Swiping Down Notification Bar / Back It Up - Hit Back Button?

Instead of trying to grab the notification bar and swiping it down, simply start ABOVE the screen and swipe down. Fast or slow makes no difference.

You can swipe it back up, or simply hit the back button.

Android :: Android - Override Back Button To Act Like Home Button

Jan 4, 2010

On pressing the back button, I'd like my application to go into the stopped state, rather than the destroyed state. In the Android docs it states: not all activities have the behavior that they are destroyed when BACK is pressed. When the user starts playing music in the Music application and then presses BACK, the application overrides the normal back behavior, preventing the player activity from being destroyed, and continues playing music, even though its activity is no longer visible


How do I replicate this functionality in my own application? I think there must be three possibilities.

1) Capture the back button press (as below) and then call whatever method(s) the home button calls...........
