There's no method available to us to display a callout / bubble above an ItemizedOverlay item when, tapped, right? I don't think there is, just wondering if I'm missing this in the docs before I start my own.

I have made an Android app that shows a MapView with two overlays, one MyLocationOverlay and one custom overlay. I am programmatically zooming and panning to what I want the map to show. It also auto pans to my current location. The auto pan is moving the map away from what I want to show.
So my question is simply: How can I disable the auto pan?

Is there a way i can set a minimum zoon level for my MapView?. I don't know if you've realized the map looks really ugly when zoom level is one. You see the whole world map replicated. I would like to avoid that zoom level no matter if user is zooming in through gestures or zoom controls. I've looked at different alternatives, but none seems to work. Does somebody have a good idea about this?

How can i disable the panning/zooming functionality of a MapView (not the zoom controls, i want a wholly static map)?
I've also noticed that touching the map doesn't seem to trigger the MapView onClickListener, could anyone elaborate why?

I have been trying to get this seemingly simple problem fixed for about half a day now. I have a working MapView and I just want to show the default zoom keys and have them there all the time. They do not appear at all - it's not that they appear then go away.
Code...
I have tried commenting out the setZoom and tried moving the setBuiltInZoom controls to the updateLocation method. I've found a lot of posts in relation to this problem but none that solve it.

I've been searching for this for quite a while and never come across a way to do it. In the Google Maps App, when you search for directions, there are overlays with buttons in them, and I want a similar thing, a marker with an image, text and button inside.
I've implement ItemizedOverlays before and made the marker clickable which I would event be happy with if I could put a linear layout inside the marker to organise the image and text since they are different for each marker.

I'm very new to Android (like 2 days), but I'm experienced with other layout toolkits. I'm trying to put an AdView below a TabHost, and it seems that I can either get the TabWidget or the AdView to display correctly, but never both.
First, here's an ASCII art version of what I'm trying to accomplish:
--------------------------------------------
| Tab 1 | Tab 2 |
--------------------------------------------
| MapView when tab 1 is selected |
| |
| |
| |
| |
| |
| |
--------------------------------------------
| AdView that stays no matter what tab |
--------------------------------------------
As you can see, I'm trying to get the AdView outside the TabWidget or FrameLayout. I want it to be below the whole tabhost contents.
Here's the layout I've got before adding the AdView...
Unfortunately, in that one, my MapView in the first tab puts the Zoom controls on top of the AdView. Is there some simple layout I'm missing? Cuz I can get the TabWidget to wrap_content for height, or the AdView to wrap_content for height, but only when they go above the "@android:id/tabcontent."
Anything below the tab content gets eaten by the MapView.

I know there is zoomControls which can be added to the view. But it looks like I have to take care of the zoomin/zoomout actions myself. Is there a simple class that will take care of the zooming and panning automatically?just like the map behavior but without the map.

I am experiencing a problem with my app. The 1st screen that appears is a map that displays pins that are located based on an XML file that is loaded from our server.
Sometimes the app loads as expected. Other times, the map loads but none of the pins appear until you touch the screen.

I can use the built in zoom controls for WebView or MapView. But don't know how to access the control for View or ImageView. If the control is not implemented, can we access the bitmaps for the zoom control supporting WebView or MapView.

Droid Incredible 2.2 no root default camera app user. When I tap to focus on the camera and am really close to something it goes from blurry to sharp and then blurry at the last second (when it snaps the picture) I took this video to demonstrate what I mean. Is there any way to take a picture like this? Or to manually focus with the stock camera app? Or an app that will help me take good quality macro pics of coins, pins, etc. I will pay for an app. I saw posts with the macro camera lens but I have no desire to glue a metal washer onto my camera lens.

I am trying to set up a ViewFlipper that changes a SlidingDrawers content each time a button is pressed. So far every view I set up worked fine, but now I am trying to create a ListView (including single_choice_mode) within a child view of the ViewFlipper, but my attempt only let to a NullPointerException. As I only discovered ViewFlipper today, I am not yet familiar with it and may not have understood it completely. if someone could give me a hand and help me find out what I have done wrong, that would be great. Here is what I have done:
The code for the onClick event of the ImageButtons:
public void onClick(View v){
if (v == btnExposure){
mFlipper.setDisplayedChild(0); }
else if (v == btnProperties){
mFlipper.setDisplayedChild(1);}
else if (v == btnSpecialEffects){
mFlipper.setDisplayedChild(2);.............

My problem is my MapView becoming very laggy and so non-responsive at times, that Android thinks its hit deadlock and tries to close it.
I am adding 60 overlays to the map view and i originally thought that the icon size may be causing the problem by using up all the memory. When i decreased the overlay icon size, it did improve things, though it is still to slow to be usable. Has anyone experienced anything similar and have a workaround? There may be a better way of doing it other then extending the Hello MapView example.

I have subclassed Overlay as LandMarkOverlay (and implemented an onTap(GeoPoint) method).
In the main activity I do this:
setContentView(R.layout.main);
MapView mapView = (MapView) findViewById(R.id.mapview);
mapView.setBuiltInZoomControls(true);
landmarkOverlay = new LandmarkOverlay();
//add the landmarkOverlay to the list
mapView.getOverlays().add(landmarkOverlay);
What else do I need to do so that when the user taps the screen, landmarkOverlay's onTap(GeoPoint) method gets called?

I have a DROID using Android 2.2
I am attempting to get the simplest MapActivity to run on the device. (NetBeans latest and greatest using a Google Api build target.)
I have all the appropriate Manifest entries, the simplest OnCreate --- > all it does is setContextView() to the xml with a mapview in it.
