I've implemented a Class that extends Overlay and also override the onTap / onTouchEvent (tried both). Right now it seems like that event is triggered when you tap on the map regardless of position.How can I make sure that the event is triggered only when you tap over the overlay you have added?

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.
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 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.
Could 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. I'm using the sample program given in the Google Android Website http://developer.android.com/resources/tutorials/views/hello-mapview and i want to extended it to the next level. Import com.google.android.maps.GeoPoint; import com.google.android.maps.MapActivity; import com.google.android.maps.MapController; import com.google.android.maps.MapView; import com.google.android.maps.Overlay; import com.google.android.maps.OverlayItem; import android.app.Activity; import android.graphics.drawable.Drawable; import android.os.Bundle;

This can I obtain following the tutorial: http://developer.android.com /resources /tutorials/views/hello-mapview. But now I like to put a button on the overlay window. That button should open a detail activity. How can I make this? How is possible to personalize the overlay "info window"?
View 2 Replies View RelatedI'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 have a mapactivity with multiple ItemizedOverlays and a onTap method when the user clicks on the marker. I can show a toast message but i want to display a Dialog when the user clicks on the marker (so in onTap method). How can i do that?
View 2 Replies View RelatedI've been pulling my hair out trying to achieve smooth scrolling in an OpenGL-based app on Eclair. It seems that no matter what I do, I cannot get more than 36 events per second (the rest is sent in history data which is useless in my case). This happens on both the emulator and the Motorola Milestone.Is this a hardcoded limit or am I doing something wrong? I'm implementing onTouchEvent on the activity and recording how many events are received per second and then send that info through Log.v to Eclipse. I also tried implementing onTouchEvent on the view instead of the activity and the results are the same.
View 4 Replies View RelatedWhen 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 want to catch any onTouchEvent() on the mapview. After search lots of questions&answers, I found only when I write my own MapView(MyMapView)and define onTouchEvent, then use this MyMapView in main activity.

I am stuck in a situation,where I have onClick() method & onTouchEvent method. The situation is the my onTouchEvent is handling the fling gestures (like left,right), after each fling i am changing the Layout & presenting new one for the user. On each layout i have some buttons & they have the onClick() set. Now when i do the gesture nothing happens & sometimes the onClick gets called. how i can make these two methods to work correctly?
View 4 Replies View RelatedI've got a problem with a flood of touch events destroying my game's framerate while there is a touch active. Basically onTouchEvent is called (with getAction = ACTION_MOVE, x = 0 and y = 0) about a hundred times a second for as long as the finger is touching the screen. I've tried returning from onTouchEvent straight away, and even removing its implementation at all, but it doesn't help - the app slows to a crawl as soon as a finger is down. I asked on the IRC channel and Romain Guy advised me that they're aware of the problem but didn't have time to fix it for Cupcake, so I'm not expecting a full solution!

View 2 Replies View Relatedi need left, right motion event and a click event . problem is that, if i have onclickEvent then onTouchEvent doesn't fire. onTouchEvent works only if i disable onclickEvent and also it doesn't work what i expect.
1-only ACTION_MOVE fires twice everytime when i move on screen.
2-can't get left and right motion.
I've got an onTouchEvent boolean on a Surfaceview, I've got openGL objects drawn on the view and I'm wondering is there anyway to detect where on the screen the onTouch happened? e.g (x,y) co-ordinates.
View 1 Replies View RelatedI'm making an application which will utilize both touchevents and sensorevents. The problem with touchevents is that they fire off very often, and thereby consumes massive amounts of CPU time. The common solution is to do a Thread.sleep to make it cool down.However, if one wants to use both the onTouchEvent and onSensorChanged in the same activity, applying the Thread.sleep hack will also slow down onSensorChanged. This is obviously caused by the two methods being called from the same (ui) thread.Is there some way to call onTouchEvent from a different thread than the ui, so one could do the Thread.sleep trick without slowing down onSensorChanged as well?

View 6 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?
