I have been looking this but haven't found a concrete example is there a way to click a specific point on a Map and then draw a overlayitem it?

I'm a huge fan of the old school point and click adventure games (Monkey Island, Sam and Max, Discworld, etc) and am hoping to find something in this genre for my new HTC hero. Any suggestions? Also, I know there's a ScummVM port, does anyone have any experience with that? I'm afraid direct ports will not work well on my 3.2 screen.

View 2 Replies View RelatedI'm currently writing an app displaying a MapView showing a google map. I used the "hello map view" tutorial from http://developer.android.com/resources/tutorials/views/hello-mapview.html and this works so far: the map is displayed, centered and zoomed correctly, even the OverlayItems I added are displayed correctly. But when I click on one of those overlay items I added, the application crashes with a null pointer exception:

when I click on one item in the ListView that item's background changes to light gray, but when I continue to scroll through the list every 4th item has the background changed to light gray even though those other items have not been clicked. How do I make only the item I clicked be effected by the click?
ListView lv = (ListView) findViewById(R.id.resultsList);
lv.setAdapter(new ArrayAdapter(this, R.layout.resultitem, (String[])labelList.toArray(new String[labelList.size()])));
lv.setOnItemClickListener(new OnItemClickListener() {
public void onItemClick(AdapterView parent, View view, int position, long id) {
TextView tv = (TextView)view.findViewById(R.id.result);
tv.setBackgroundColor(Color.LTGRAY);
tv.setTextColor(Color.BLACK);
I have a ListView in my Activity. I am trying to catch both a click and a long click (which should bring up a context menu).
ListView lv = (ListView) findViewById(R.id.MyListView); ... lv.setOnItemClickListener(this); lv.setOnCreateContextMenuListener(this); ...
I notice that if I have both the click and long click listeners up, I won't ever get the long click listener (i.e. the context menu). If I remove the setOnItemClickListener() call, i get a call into
@Override public void onCreateContextMenu(ContextMenu menu, View v, ContextMenu.ContextMenuInfo menuInfo) {

I have just started my career as an android programmer, and am currently relying heavily on the sample code and api examples. I have been working with this api example, to produce an expandable list of items (note this example does not use the ExpadableListView).In playing with the example, I tried to add another widget that would become visible and be gone at the same time as the text (mDialogue in the sample code). This works well with another TextView, but as soon as I tried to add a button widget, it stopped working. The list would expand on first click, showing my hidden TextView and Button, but it will not disappear on further clicks. The button is however, clickable, and I was able to set up an onClick listener to change the button text back and forth.I'm starting to wonder, is it just not possible to have a clickable item inside a clickable list item? Or is there some kind of work around? Would it solve my problem if I used ExpandableListView?
View 1 Replies View RelatedI've now had and used my Samsung Moment for a full month now, and I have to say this is the best phone I have ever used.
I carry multiple smartphones on me, usually a Blackberry of some sort, Palm Treos / Centros, iPhone, and now my Samsung Moment. While all the smartphones are really good, the Samsung Moment has been really great.
Despite all the complaints you read here, I have only had a couple of minor annoyances:
1. The Google Calendar widget doesn't default to the current day when you click on it. I have accidentally entered appointments for "today" when I realize a bit later that it was on another day that I had scrolled to previously. I hope there will be a setting to always display the current day in the future.
2. I use Astrid to sync my to do list with Remember The Milk. Anytime I add a new task if I'm using the physical keyboard, and slide it shut and go to the portrait mode for the virtual keyboard, somehow my text is wiped clean and I have to start from scratch again.
The battery life is excellent. Based on my moderate use, I easily get 2-3 days out of my phone, which is as good as my Palm Centro or my Blackberries.So glad I have this phone, can't wait for future updates though to play with.
When I DL'd the GDE app, I accidentally set my stock droid "HOME" screen as the default screen when the popup box came up asking me to choose between stock Home and GDE. Now when I click on GDE and click the home button, it switches back to the stock Home screen. How to I switch the settings now to set the GDE app as the new home screen?

I understand that Android Marketplace is not available on the internet, just from the phone.I would, however, like to point people to my application if possible.

View 1 Replies View RelatedI'm trying to create a compass for my application BUT the difference is that, instead of having a line always pointing to north, I want this line to point for a specific point. I've been trying dozens of algorithms and nothing works. I've finally found one that points me exactlly to the point I want. But it doesn't move if I change the position of the device which is my objective. Basically, what I want is that no matter the direction I'm using my device. The line always point me to the point (picLatitude,picLongitude). I understood that for the line to move, I can't use static variables. I need to use the values offered by the onSensorChanged(SensorEvent event). This are the data I have available:
event.values[0]: azimuth, rotation around the Z axis (device in relation to north, 0º) event.values[1]: pitch, rotation around the X axis event.values[2]: roll, rotation around the Y axis mLatitude: device current latitude got from GPS (variable) mLongitude: device current longitude got from GPS (variable) picLatitude: static picture latitude established previously picLongitude: static picture longitude established previously distance: distance in Km from device to the picture calculated previously
And this the formula that works correct, and gives me the correct angle. (But it doesn't use any of the Sensor Data so the line Compass doesn't move):
double dLong = picLongitude - mLongitude; double y = (Math.sin(dLong) *
Math.cos(picLatitude)); double x = (Math.cos(mLatitude) * Math.sin(picLatitude) - Math.sin(mLatitude)*Math.cos(picLatitude)*Math.cos(dLong)); double angleDegreesWrongRange = Math.abs(Math.toDegrees(Math.atan2(y, x))); float angleDegrees = (float) ((angleDegreesWrongRange+360) % 360);
myCompass.updateDirection(angleDegrees);
I got this "bearing" formula from this website: http://www.movable-type.co.uk/scripts/latlong.html. I've try adding, subtracting, the azimuth.. I've tried with the others, seriously at this point I'm just demoralized.
Does anyone know if there is an app out there that has cedar point mapped out? I cant seem to find one. Im heading there tomorrow and would like to be able to ditch the map and just carry around my phone.

I am at a stage where I can understand and write a decent Android application. At this stage, I am still not comfortable with SurfaceHolder, Canvas, View invalidate() etc. I don't have a CS background so I must've missed these from a CS Graphics course or something.
Starting directly with Android seemed like a bad idea because there are not many examples out there. And sometimes I am getting things done, but I don't understand what the heck is going on. For instance, there are a few dangling observations. Calling invalidate() from within a view calls its onDraw method but from outside it doesn't do anything and I don't know why this is happening. I know SurfaceHolder can be a powerful thing but I don't know how to use it.
For an absolute beginner to be able to handle this stuff, what are the resources one should follow? Is it animation basics or screen rendering or something else altogether? I mean, it cannot be the case that Android guys invented these concepts right? They must be similar to something out there which has some tutorials already. My end goal is to put myself in a position where I can write some simple custom views that can animate themselves and use some basic physics to react to touch events.
I was wondering is it possible to get a notification of when a new configured network is added to the Wifi Manager in Android? I know you can get the current list of configured networks.

But is it possible to get notification of when a new one is added? I don't see anything in the Wifi Manager that would be helpful. How this could be achieved?

View 1 Replies View RelatedI've started developing an OpenGL ES app and I would like to get the best possible performace (as everybody, I guess).
As far as I know, HTC Magic (myTouch, G2) doesn't have floating point unit, so I think every calculation is done internally with fixed point math. That beign the case, altough I fed OpenGL with floating point vertex positions and normals, there would not be any permormace penalty since it would be using integer math instead of floating point emulation.
I have been searching about the floating point support on G1 phone (aka the HTC Dream phone) for a few hours.
So far, my conclusion is that the ARM-based Qualcomm MSM7201 CPU does not have VFP (floating point coprocessor) and therefore floating point calculations have to be done via software-float.
This is quite disappointing as I am interested in developing applications with heavy math.
However, I also notice that the Qualcomm CPU has QDSP4000â„¢ and QDSP5000â„¢ high-performance digital signal processors (DSP), according to http://www.qctconnect.com/products/msm_7201.html
Therefore, here is my question: would it be possible to leverage the DSP modules in the MSM7201 CPU to do the floating point math?
Also, I would like to develop the heavy-math modules in C/C++ and call it via JNI, and so I just want to double-check whether this is a feasible approach.
I'm currently developing a application on a HTC Dream aka T-mobile G1. afaik the processor has a FPU coprocessor, called VFP (Vector Floating Point) in ARM terms. So far I couldn't find any information about if the FPU is used for floating point calculations or if those are emulated in software. does anyone have any information about that? the opengl implementation supports both fixed point and floating point. will my applications be slower when I'm using floating point, because they get transformed into fixed point internally? or is floating point implemented in hardware?
