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 ?

I'm trying to show a simple layout where I can call this activity and fill in some values, then hit the save or cancel button. Unfortunately the save and cancel buttons never appear. Can someone help please?

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 have various activitys on my app. I have a configuration Activity, and i want to put a cancel button, that, when user press this button, the configuration window get's closed and turn back into the previous activity.i search in google and i find something about calling cancel or dismiss functions, but i can't call them cause this is not a dialog, it's an activity

Basically I have created a blackjack game (first using just java) and it falls under an infinite while loop (this is so that the deck data is kept and everything works well. So first it deals the cards and then it needs to wait for either the hit button (which is displayed) or the stand button (which is displayed) to be clicked. I initially did this with a while loop that would keep checking if buttons were hit (basically when a button was hit, a static int would change and stuff would occur). However this just causes the droid to freeze up (thus far anyway) and also not refresh. So please someone tell me there is some way I can have my method pause until a button is pressed? I also need to know the proper way to use invalidate() so that my textviews, pictureviews and such can be updated as the methods change them.

View 13 Replies View RelatedI have 6 options to put in options Menu, but 3 of them are not so important and i want to hide them in submenu. All of my Activities are started from one ActivityGroup which creates Menu on MENU button press. Problem is that when I open SubMenu or Dialog (which is created and displayed by ActivityGroup) my current foreground activity makes onPause, onStop and onDestroy, and when I close this submenu (using "back" key) or dialog (by "ok" button for ex.) I don't have any response (onCreate, onResume) from any of my activities registered in LocalActivityManager.

View 17 Replies View RelatedI have tried to make a series of dialogs, like a questionnaire, that the user needs to answers a series of questions selecting one or more checkboxes. I can do one, just fine, but when I try to make more than one question (lets say 10), it does not show, or show all the dialogs. I tried using dialogs or new acitivities.
So, my problem is I have multiple questions, one to be presented each time, and I need to wait for one to be responded so I can ask the next one. How do I accomplish this?
My first attempt was with a dialog box... but obviously it got all the boxes stacked in each other:
CODE:.................
I intended to show a dialog in a service process, then I tried to use the AlertDialog but got the below error message: WindowManager$BadTokenException: Unable to add window -- token null is not for an application The reason seems to be that the dialog is not used in a application context (activity should be fine?) Was there any way that can solve this problem?
View 2 Replies View RelatedI wonder what is the right way to implement this? Could anybody advice whether my solution is correct?
So:
Activity is created
User clicks on button and dialog is launched (Dialog, not dialog styled activity)
User opens keyboard
we have onSaveInstanceState called where we save that our dialog was opened and all respective dialog input
we have onRestoreInstanceState and here we check whether dialog was shown, recreate the dialog with respective input.
Is it the right approach? or there is smth. that is done by Android and I am doing some redundant actions.
I use the AlertDialog class in my application. By default, these alert dialogs have a transparent background. I'm trying to use an opaque background instead, very unsuccessfully.
These are my styles:
CODE:....................
I applied the "MyOpaqueActivity" style successfully for whole activities (the window background is changed to "my_background"), but it doesn't work for alert dialogs within those activities. The "alertDialogStyle" attribute and my "MyOpaqueAlertDialog" style don't seem to have any effect.
So how can I change the background of these alert dialogs?
I am trying to create a map application and I need to do something similar to what Google Maps does. I want to open show a list of locations and when user taps on them I want to show a dialog.
I was able to do it till here. But now when the user clicks on the dialog that opened I want to show another acttivity with the details of that item that they clicked on.
I tried to start a new intent but it gives me an error.

I've read on Reto Meier's blog that he doesn't recommend the use of modal "Loading" dialogs in Android applications. Is this a general consensus among developers? If I have a login screen what should I display when the user tries to sign in? Until now, I have used a "Signing in" indeterminate progress dialog. Should I use the application's progress bar? Should I use a Toast? And, in the general case, when should I use dialogs and when not to?
View 1 Replies View RelatedI am rendering an EditText as one element of a list-style AlertDialog (which is backed by the default ListView implementation). I sort of expected that this circumstance would not change the behavior of EditText, but it does: a click on the EditText does not spawn the soft keyboard anymore.
After an hour of messing around with focus settings and click handlers I got fed up and debugged into InputMethodManager.showSoftInput(), and found this:
CODE:....................
The problem here is that mServedView is the ListView that's backing the dialog, while view is the EditText, and ListView.checkInputConnectionProxy() does simply return false in the default implementation of ListView (to be overridden by subclasses).
Worse, I couldn't find a way to set a custom ListView which allows proxying IME reuqests; AlertDialog.Builder.setView() accepts a custom ListView, but this is not the ListView that InputMethodManager sees.
i want to display a dialog in my android application where certain TextViews in the layout need to have content set during runtime. while showing the dialog itself is no problem at all, accessing the TextViews via TextView.setText(String) crashes the application.
View 2 Replies View RelatedI've had this problem in a few different apps now and I can't seem to find a solution.
If, in the onCreate() of an Activity, I start an activity that uses the dialog theme it doesn't draw anything to screen... the whole screen stays black. All the views are there (e.g., I can tap where an EditText should be and it'll give me the keyboard), they're just not visible. code...
Does anyone know how to make a dialog fill the screen width in landscape mode? Setting the layout's width to fill_parent doesn't do it. It always comes up portrait width, or something suspiciously similar.

View 3 Replies View RelatedI am rendering a ListView inside a dialog. The ListView elements are very simple TextView objects. The problem: whatever I do, they never take the full width in the list view, which has the side effect that the list view selector only covers the actual text, not the whole list entry (i.o.w., if the text of the entry is much smaller than the width of the listview/dialog, then only a tiny portion of the list element is highlighted when focusing it).

I am working with the time and date example in the android api demos, and I want to put all the code relating to creating the time and date dialogs setting the values etc into a separate java file, and in my main java file run when the application starts, just declare the buttons and onclick events.
What is the best way to do this? Do I need to put all the code inside a class(that extends activity) or method? How do I use this inside my main class. Code...
I don't know how to position the progress dialog(the one with the rotating image). When my application starts its display an full screen image and a progress dialog box. I need to moved the progress dialog box a little lower.
