Android :: How To Close An Activity When User Clicks On Home Button

Feb 19, 2010

I understand that trying to capture home button clicks is a hack, but I need to atleast close my current activity when the user clicks on home button. Is there anyway I can tell the system to close this activity is the user clicks on home button? If so how can I do that? I need to do it as I am listening for location updates and I want to stop the updates and also need to trash any location that was available to me previously. I need to do this just in case any user while in that activity clicks on home button and changes the location settings.

Android :: Multiple Back Button Clicks Needed To Exit Application

Jul 30, 2010

In my current application design, I have an activity class application.java (which starts on launching the application), and it does not have a layout(UI screen). I call another class called servicebind.java from the onCreate method of my 1st class. here I bind to the local server (bindServer()). i call back the application class through an intent. Once I am back to my application class, I call my activity class called welcome.java which has a layout/UI. When I run this application, I am able to see the welcome screen. But the problem is, when I click on the back button, I get a black screen with just the title on top. I have to hit back button 3 times to exit the application.

The reason I see from the logs is that, the 1st 2 activity classes (application.java and services.java) does not get destroyed unless I hit the back button. So the 1st time I hit back button, the welcome activity gets destroyed. the next back button destroys the servicebind class and final back destroys the application class. Is the reason because these classes dont have a UI to display in the onCreate method. I do not want to change my design where I bind the service in the servicebind class and call the welcome activity in the application class.

Android :: How To Override The Back Button So It Doesn't Finish() My Activity

Jun 29, 2010

I currently have an Activity that when it gets displayed a Notification will also get displayed in the Notification bar.

This is so that when the User presses home and the Activity gets pushed to the background they can get back to the Activity via the Notification.

The problem arises when a User presses the back button, my Activity gets destroyed but the Notification remains as I want the user to be able to press back but still be able to get to the Activity via the Notification. But when a USER tries this I get Null Pointers as its trying to start a new activity rather than bringing back the old one.

So essentially I want the Back button to act the exact same as the Home button and here is how I have tried so far:

CODE:.........

However the above code still seems to allow my Activity to be destroyed, How can I stop my Activity from being destroyed when the back button is pressed?

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

Mar 31, 2009

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 :: Prompt User To Save Changes When Back Button Is Pressed

Mar 17, 2010

I have an activity that contains several user editable items (an EditText field, RatingBar, etc). I'd like to prompt the user if the back/home button is pressed and changes have been made that have not yet been saved. After reading through the android documentation, it seems like this piece of code should go in the onPause method. I've tried putting an AlertDialog in the onPause however the dialog gets shown and then immediately tears down because nothing is there to block the pause from completing.

Android : User Action Emulate Hardware 'Back' Button?

Sep 6, 2010

I looked around and although there are many related questions I didn't see one that answers my exact question:

I would like to create an app that runs in the background that provides the exact same functionality as the hard coded 'Back' button in all cases.

The reason? I (for example) have a Droid X, and it is BIG. it makes it extremely hard to use one-handed and having a swipe gesture function as a back button (like in Palm Pre for example) would greatly increase the ease of use.

as far as I'm concerned the app could just be one simple class that contains:
1) a listener for the 'back' swipe
2) a call to the physical hard button itself

Is this possible? are there built in APIs for the hard coded buttons that would allow me to call them without actually pressing them?

Again - I'm not interested in overriding the button, I'm interested in making a software call to it - or failing that, in emulating it's behavior in any and all states and other apps!

Please forgive the naivete of this post. I am a very novice programmer and really I just want to know whether this is possible before I start to devote myself to trying to build it.

Android :: Application Crashes When User Presses Back Button / Where To Put Code?

Oct 6, 2010

First of all, maybe i went about this the wrong way in the first place. Situation is, i have a listview that when an item is clicked, it creates an intent and calls startActivityForResult() to another activity, to be able to edit the entries in the row. and that other activity after editing the required values, returns back to the calling activity, when the user clicks on a save button. The activity then uses the row Id to update the item.My problem now is that, if the user presses the BACK button instead, the application crashes. i have been looking around and see solutions like using Shared Preferences or onSavedInstanceState(), but i don't know where exactly i should be putting the code?

Android :: Prevent Activity From Saving State When User Selects Back Button

May 2, 2010

I have an Activity with a list that is bound to a ListAdapter reading data into a ArrayList from a database. All is well when the data is first loaded. While the Activity is open and the list is being displayed it is possible and likely that the data in the database will be updated by a service but the list does not reflect the changes because the ArrayList does not know about the changes. If the Activity is no longer in the foreground as would be the case if the user goes to the home screen and then is brought back to the foreground I would like for the Activity to not display what it did prior but rather reload the data using the ListAdapter the view is bound to. I think something needs to call finish() but I am not sure what.

This is what I have in the Activity.

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

Android :: Logging To A Database When User Clicks On A Widget

Jan 14, 2010

I have a widget that displays an analog clock. What I would like is for the the widget to write to a database the time when a user clicks on the widget. I've already got the databaseHelper class and have an Activity that displays a screen showing the current date and time and writes the time to a database.The AskTheTime class extends activity and logs to the database in onCreate(). But this means that it displays only the time when the widget was started - not when it was clicked. (I guess this is because I'm starting a pendingIntent) I'm not sure If I should put the database write in another method or if I should be using Intents to do this sort of thing from widgets. Any pointers would be great! I've look at several tutorials for intents but none of them seem very clear to me.

Android :: Does Pressing Back Always Cause Activity To Finish()?

May 10, 2010

I've heard that pressing the back button will essentially cause the current Activity to finish(). Is this always the case? Seems like it would be with the way it pops the Activity off the stack.

The one situation I'm not so sure about is when the root Activity in a Task has back pressed. I'm currently experiencing a very weird effect, described as follows:

On loading my application, the first Activity is for initialization, and once it finishes, it calls my main Activity (a TabActivity). This first init activity has android:noHistory="true" set in the Manifest so pressing Back from my main Activity won't go back to that. It goes to the Launcher. When I click on my App in the Launcher a second time, the initialization activity loads again, and loads the main Activity when done. Almost immediately after, it loads a second instance of my main Activity. But ONLY after the Application has already been run once, and was exited by pressing BACK from the main Activity. It does it every subsequent time until I force quit the app or load a new version from the IDE.

Based on this, I am suspecting some kind of Activity instance is lying around and being reused, since it only happens on the second+ time I run the application (and exit with BACK -- using HOME just returns to the last state of the app, no big deal).

Android :: Android - Keeping Options Menu Open After User Clicks On Menu Item

Nov 19, 2010

I have an Options menu up and running in my Android application and I've overridden the onCreateOptionsMenu, onOptionsItemSelected and onPrepareOptionsMenu methods to customize the menu a little. My question is related to keeping the Options menu open after the user clicks on a menu item. Basically, I'd like to be able to hide the menu until the user clicks on the device menu key. Once the user clicks on this key, I'd like to be able to hold the menu in place regardless of how many times the user clicks on menu items. If the user wants to hide the Options menu, they'd just need to click on the device menu key again. Is this type of interaction supported (or even advisable).
