I'm using Google maps. I put the markers on map and my inherited ItemizedOverlay overrides onTap() method.
Markers are 32x32 images.
However, I can tap quite a bit away from the marker and still receive the event. This becomes a problem when markers are close to each other.
I have a MapView where I would like to be able to tap the map to create a new item at that location if there is no item there, or display the info about the item if there is.
I tried overriding both the onTap(int) and onTap(GeoPoint, MapView) methods but apparently if the second method is overridden the first never gets called (commenting one or the other lets each one work as I expected).
I thought about just checking if an item was at the location, but there doesn't seem to be any handy methods available to do that (other than iterating through the list of items and checking each manually).
I have an Overlays class named picOverlay which extends ItemizedOverlay<OverlayItem> that uses a drawable named ''overlay''.
I'd like for my application to change the drawable to let's say ''overlay_hover'' when the user touches the overlay.
Can I do this in the onTap method? Can someone enlight me a little bit on how to change the drawable that I'm actually touching?
I am wondering if I am going about this problem the correct way.I am making an app that places overlays on top of google maps.When you click on the overlay it should launch a dialog type window that will give you options on what to do with that overlay.It is the line startActivity where the app throws an exception.I did the setFlags because an error message said it was needed because I was trying to start the Activity while outside an Activity.That makes me think I am going about this wrong.I have 'MyActivity' listed in my manifest so I don't think that is the issue.I have searched for this problem on the internet and I can't seem to find anyone else running into this so that is another reason I think I may be trying to do this the wrong way.
View 3 Replies View RelatedI am attempting to launch a dialog type window when I click an Overlay that has been placed on google maps. I thought the way I would do this was Override the onTap() method, create an intent, and call startActivity on that intent as follows:
CODE:..........
It looks like the program throws an ActivityNotFoundException when executing that last line. The exception reads that if you try to start an Activity while you are not in an Activity you need to set the FLAG_ACTIVITY_NEW_TASK flag which is why that line is there. I have included MyActivity in my manifest.
'context' is passed to my class constructor that extends Overlay and is the MapActivity that I am using to display the map.
When I add a new item to my ItemizedOverlay the onTap display I have set appears X times, where X is equal to the number of items that I added. So for example, if I add one item and tap it, it the onTap method gets called once, and in the LogCat I get:
02-04 23:28:56.188: INFO/NotificationService(52): enqueueToast pkg=android.mapit callback=android.app.ITransientNotification$Stub $Proxy@4394c100 duration=0
If I add a second item and click ANY of the other items, the onTap method gets called twice and I get the following in LogCat:
CODE:.....................
If I add a third item and click ANY of the other items, the onTap method gets called three times and I get the following in LogCat:
CODE:...................................
Any idea why this would occur? I'm running into issues with it affecting other things like removal of items.
I looked for any information about onTap event processing for itemized overlays in this group. There is a lot of useful information but I could not find the answer to one question.
The tutorial by Mark Murphy on itemized overlays, http://androidguys.com/?p=1413
describes how to generate a Toast message whenever an onTap event occurs. In his case, the custom itemized overlay activity is included in the main activity. In my case, it is not. My custom itemized overlay activity is included in the application package as a public activity.
This means that the line Toast.makeText(NooYawk.this, items.get(i).getSnippet(), Toast.LENGTH_SHORT).show(); will not work "as is".
I have had trouble in correctly identifying the context for the Toast. Attempts to use the main class' (the one calling the custom itemized overlay class) context have not worked. I would appreciate it if anyone could suggest how I could resolve this issue. Incorporating the custom itemized overlay class in the main class is not a desirable option.
Alternatively, I would appreciate any suggestions for generating a display of the title and/or snippet information for markers on a map.
The onTap event works fine (Log.i statements in the onTap method display the correct information for each marker tapped)
I'm trying to display a popup in a MapView. I m doing this in myLocationOverlay.onTap() method. I got the initial popup to display correctly. I have a button in the popup to expand the popup by making some hidden view visible and changing the height of the popup like this..
but the height of the popup doesn't seems to change. Am I missing something here?
I have several Overlays drawn on a MapView with ItemizedOverlay, and an onTap that works when I first start my app. However, if I press the Back button on the Android then start my app again the onTap does not work at all. Other touch sensative operations work fine, like long press on the map and several face buttons. It is also fine if I press the Home button on the phone then go back into my app, so its only on the Back button. It will also work if I first open another app like the Maps app, then go back into my app, acting like a reset.
Overriding the onBackPressed method to move the task to the background also does not work, does anyone have any ideas what would cause this? It happens in both the emulator and on a real device.
I don't know if it will help but here is the relevent code:

I'm scaling markers on a MapView with the following code
CODE:.........
And:
CODE:.............
Which works, but the shadow below the marker has wrong offset when scaled. Also; i override the public boolean onTap(int index) in ItemizedOverlay to detect taps on the markers, but it seems inaccurate. I can click some range outside the marker and still trigger onTap...
I have an activity that has a button which opens a new MapActivity to select a location by tapping on the map.
The map has an overlay that overrides the onTap method to get the location but I want to return that location to the previous activity but, I don't know how to return the geopoint to the mapactivity in order to call the setResult() and finish() methods, because I can't call them from the Overlay.onTap method.
I have a dialog with edittext for input. when i click yes button on dialog, it will validate the input and then close dialog. However, if the input is wrong, i want to remain in the same dialog. every time no matter what input it is, the dialog always automatically close when i click button. How can i disable this. By the way, i use PositiveButton and NegativeButton for the button on dialog
View 2 Replies View RelatedIn the description of how to add a list of options to an AlertDialog the official Android documentation alludes to saving a users preferences with one of the "data storage techniques." The examples assume the AlertDialog has been spawned within an Activity class.
In my case I've created a class that extends ItemizedOverlay. This class overrides the onTap method and uses an AlertDialog to prompt the user to make a multi-choice selection. I would like to capture and persist the selections for each OverlayItem they tap on.
The below code is the onTap method I've written. It functions as written but doesn't yet do what I'd hope. I'd like to capture and persist each selection made by the user to be used later. How do I do that? Is using an AlertDialog in this manner a good idea? Are there better options?

I am having a problem about repeating Login dialog (an AlertDialog) and progress dialog, coordinating with http thread. I suppose repetitive Login dialog (if fail, continue) handling should be common and straightforward. I guess my approach must be wrong somewhere. I already spent 2 days on this and am desperate. So please help. User starts the app, the main activity starts.Show a login dialog (generated by the main thread, i.e. from on Create. The main thread then starts a wait_thread, which will wait for http to return data and check the data and decide what to do.After user input username/password and press login, a progress dialog starts.The progress dialog starts an http_thread to talk to the server and get replies. Once done, it will notify the waiting thread.If the user type in the right username password first time, the code works fine.But it always fail for 2nd time Login, i.e. When first login fail(wrong username/ password),the wait_thread will generate 2nd Login dialog to let user repeat the login process. But after user hit the login on this 2nd Login dialog, the system always crashes.

My question is how to implement this Similar result by extends dialog or alertDialog.
I'm trying to get my list view to open up an alert dialog to display information when a person clicks on a selection. I have been trying several different things on the Google Developers website that have to do with this but have yet to come up with a result. Here is my code. package table.periodic;

how to create an Alert dialog in a dialog? is it possible to create? My requirement is to show mulitple dialogs simultaneously. I tried creating with the following code snippet onClick of a Button in the first Dialog and got an "BadToken" exception from WindowManager: "Unable to add window -- token null is not for an application"
AlertDialog.Builder builder = new AlertDialog.Builder(getContext()); builder.setTitle("Test Title"); builder.setOnCancelListener(new Dialog.OnCancelListener() { public void onCancel(DialogInterface dialog) { dismiss(); } });
I have a really weird problem, which I am unable to debug so far. thing is. my app needs to download something to work. So in the beginning of the onCreate() method, I check if that something is already downloaded. If not, I pop a dialog up asking the user to download it.My dialog is shown and I am clicking, so aManager.install() is called. I am passing the context because that aManager.install() pops up a ProgressDialog to show downloading progress and spawns a new thread in which everything is downloaded. So obviously before creating my dialog I make a Handler to receive the response from that aManager.install(). And the response MAY vary, because for example the internet connection isn't available (Exception raised and catched and listener called with different code).Now, when that happens (Exception) I would like to call another dialog saying "something went wrong, would you like to retry?" so another call to showDialog(DIALOG_REINSTALL) (this time with another code).thing is the showDialog() gets called (I can verify this by logging) but the dialogs doesn't show up. Instead my application JUST HANGS Does someone have a clue why it's doing this? No exception raised, absolutely nothing from logcat, I can't tell WHERE it's hanging...just see that the method is called and the dialog should be displayed.
View 2 Replies View RelatedCould anyone help me with my below program. I'm unable to put a transparent label containing the contents from my HelloGoogleMaps.java class (Hola, Mundo!) when i click the markers(the android icon) in the map. I would like to have the ontap event do it for different markers here so that that particular location details is popped up. It needs to be in a canvas display. Upon clicking this new canvas label, it should take me to a seperate activity displaying complete details.

View 2 Replies View RelatedI've implemented a Class that extends Overlay and also override the onTap / onTouchEvent (tried both).

View 1 Replies View RelatedI have a strange issue - from time to time the animation that should fade out my control (ImageButton) does not kick in immediately. I am using the fadeout animation to hide it and then in myListener on its end (onAnimationEnd) I put new resource as the image on the button.
Somewhere in my app code:
Animation a = AnimationUtils.loadAnimation(this,R.anim.fadeout); a.setAnimationListener(new myListener(location)); buttons[location].setAnimation(a); a.startNow(); // regardless if its start() or startnNow() it will work in most of the cases but not 100% reliable I actually can see in debug Log when its late, happens after few more clicks
Then in myListener.onAnimationEnd(Animation a):buttons[location].setImageResource(R.drawable.standard_button);
Seems there is a rule that the every 4th or 5th animation does not start ...
I am trying to use a managed dialog. I noticed that after the first time I display it, subsequent creations don't actually make a new instance of the dialog, they just seem to reuse the first one. If I want to stop that, and get a brand new instance on every call, is this the right way to do it?:
@Override
protected Dialog onCreateDialog(int id) { switch (id) { case MY_DIALOG_ID:
MyDlg dlg = new MyDlg(this);
dlg.setOnDismissListener(new OnDismissListener() {
public void onDismiss(DialogInterface dialog) {
removeDialog(MY_DIALOG_ID);
} } );
return dlg;
} return null;
}
So I guess the removeDialog() call does the trick, but my onDismiss() handler should be called in every instance of the dialog being killed, right (like Dialog.cancel(), Dialog.dismiss(), hitting the back key)?
