Android :: Position Views At Specific Location?
Jul 4, 2010
Is there a way to place widgets / views on the screen at any specific position required?
Something like a calendar with daily events that could overlap.
e.g. if every hour in a day is represented by 1 hour and there are 2 appointments that overlap partially (say 12:00 - 12:30 and 12:20 - 01:00) this would be drawn in the same row but the 12:20 one positioned slightly below the first.
Also there may be views (Image/TextView) that need to span 2 rows (i.e. 12:30 - 1:30).
I think a SurfaceView is one option (is this efficient?) but am not sure if there is some better layout that could be used.
We could use a TableLayout for the hour rows but not sure if there is a way to place overlapping widgets on this?

I have a layout which contains a TextView.
The content of the TextView might change on runtime. (discussed on a different issue here: http://stackoverflow.com/questions/3683727/layout-with-dynamic-position )
I can position the layout by drag&drop. If the size of the layout doesn't change, the position stays, but as soon as the size of the layout changes (because more text inside the TextView) the position is reseted.
I use the layout(left, top, right, bottom) to position the layout.
Now I don't know where I should add my layout() call to make sure it stays at the right position...
Here is my class

I need to place additional image button "my current location" to a top right corner of the MapView. Any ideas how to do this?
Making the questions generic:
1) According to MapView documentation it is possible to attach additional view objects to a MapView. How to do this?
2) How to place such additional controls into specific position on MapView?

I am using these three lines to add a compass on the MapView: mMyLocationOverlay = new MyLocationOverlay (this,mapView);mMyLocationOverlay. enableCompass(); mapView.getOverlays() .add(mMyLocation Overlay) ; However the default position of the compass showing on the screen is not too good for my apps, and I want to move it to somewhere else. Anyone knows how I can achieve that?

AFAIK accessing thumbnails for images via MediaStore.Images.Thumbnails would generate thumbnails at first attempt, and that's what i need to perform against specific location on sd card.
The question is how to make valid URI to content under specific folder?
All answers i can find use just MediaStore.Images.Thumbnails.EXTERNAL_CONTENT_URI as uri to make managedQuery. And result of it is Cursor that points to all sdcard images, while none examples can be found on how to access only specific folder.

I have a binary file which contains image. I have to jump on different locations in file to read the image file. So far I am using mark and reset methods but these are not helping me as I want. And I am using Input Stream to read the file.

I have a simple ListView and on that ListView I have placed a number of custom defined Views. The CustomView has ImageView and two TextViews.
The CustomView also has a "stateful drawable" as background, so that the background image (a 9-patch) changes if you press the Row in the ListView. When pressing the Row, the background image changes to a Red-ish thing.
The problem is that when the background changes from the default greyish, all the Views in the CustomView (ImageView and TextViews) still have their greyish background and thus creates very ugly greay boxes on top of the now redish background.
What is the best way to solve that problem? I hoped that such things were handled automatically (as it is done in for example .NET), but I was wrong it seems.

I am implementing a music player application in Android. My play list selection screen is implemented as a tab selector widget which contains a ListActivity inside each of the tabs: Artist, Albums, Songs.
I want to update the ListView in each of the ListActivity when I delete an item from any of the lists.
i.e. When I long press an item in the Artists list a context menu is drawn with "Delete Artist"
And it should delete all the songs from this artist in the Songs ListView, delete all the albums by this artist in the Albums ListView, and finally delete the entry for the artist in the Artist ListView.
Each of the ListActivity has its own fillData() method, which updates the ListView when the button in the context menu is pressed.
How can I call the fillData() method of the Albums ListActivity after I update the ListView inside of the Artists ListActivity?

I want to populate a table, defined in layout xml file through the programmatic way. I have define Table with a single row defining its header, with all the attributes set. Now i want to know a way so that i can just replicate that header row in the table with new content.
I tried using inflator inflate(int,view) method, but at runtime it showed up with error.
Here is the XML code for the layout file defining the table

I have the following XML code:.................
The idea is to change the views, whenever I press one of the radio buttons. When I press a button the first time everything works out fine, but the second time I press a button, I get an IllegalStateException, and I can't quite see why I'm getting this.
Also, the Activity seems to set all my global variables to null, which is why I have to create them every time I switch from portrait to landscape or vice versa. So I would like to know if there is a way I can save my views in the Bundle, or any other way in which I can permanently save my views, so I don't have to add or create them every time, I flip the phone. And whenever I flip the phone, it seems that it rereads the main XML file, causing the RadioGroup to be set to 2D even if the 3D button is checked. This is because I've said the 2D button to be checked from when the app is first created, but I would like to also save the state of that RadioGroup.

On my htc i was looking through display, i see g sensor calibration and i perform this calibration and after i do so the screen seems to have a delay when switch from the horizontal position to the vertical position. its weird because when i switch to the phone horizontally it switch normally and responds fast. but when i switch back to vertically it takes almost 7 seconds to actually switch back, sometimes it switch within 2 or 3 secs but never as quick as switching horizontally.

If you're already updated, shut down and repower (soft reboot) should do the trick. I actually updated my phone and after it started to do this. I restarted the phone plenty of times i even took the battery out for 30 seconds. It only does it when im texting on the browser, basically everything but the camera. He camera screen rotation is perfect. I even rooted the phone but i havent figured out how to use the root to fix the problem. Should i do a firmware update? Because i just did the htc software update.

How do you align views relative to the "middle" part of another view? I think it is best explained with a pic of the UI I'm trying to create in android.

Is there any way to query a root view of an activity for all of its child views even before the root view or its children have been inflated? I guess what I'm looking for is whether a view knows ahead of time what children it will have before it gets inflated, and can I get that list in some way. Bizarre I realize, but I think it will help me with some unconventional automation testing I'm working on. I haven't found anything in the API like this.

Let's say I have a LinearLayout, and I want to add a View to it, in my program from the Java code. What method is used for this? I'm not asking how it's done in XML, which I do know, but rather, how can I do something along the lines of (One View).add(Another View) Like one can do in Swing.

I have had androids for over two years now and am getting more and more concerned every time I download an app and seeing that it wants to READ my SMS message and Contacts.
Is there a way I can disable reading of SMS messages or any one of the other permissions by specific apps, or all apps?
Are we living in a world where any "joe schmo" can upload an app the to the app store and wait for those inadvertent downloads and collect all your personal information, and that's after all the time we spend protecting our identity and personal details?

I'm developing a mapping app using Eclipse 3.5.I'm setting the minimum update period with the LocationManager's requestLocationUpdates method, via a configuration activity. When I set the property I see in Logcat that the system process sets the value OK.When I actually send a new location from the DDMS emulator control and the location changes on the map view, I see that the system process then sets the minimum time to zero.Below is a capture of the system's log messages. You can see that I'm setting the period to 32 seconds, then 16, then, after I've sent a simulated location change the system sets it to zero.The map responds to location changes to location changes instantly even if they are sent only a couple of seconds apart.

In my application I have to fetch the current location. First it correctly fetches the location. But we are moving from the current location to some other location. It shows the previous address. It is not updating the location. My code is: locManager = (LocationManager)getSystemService(Context.LOCATION_SERVICE); locListener = new MyLocationListener();locManager.requestLocationUpdates(LocationManager .GPS_PROVIDER ,0,0,locListener); location = locManager.getLastKnownLocation(LocationManager.GPS_PROVIDER);if(location != null){latitude = location.getLatitude();longitude = location.getLongitude();} Please find the mistake and when i launch first time it is not working on second time itself it is working so check this thing also.

I have an application which uses the network as the location provider (rather than GPS eg.), however I can't seem to figure out how to send the emulator test coordinates. In DDMS I would usually send coordinates in the Emulator Control tab.Is there a place to simulate coordinates derived from the cell phone network provider?

I want to override the method enableMyLocation() in MyLocationOverlay class, in order to implement my own positioning algorithm to get latitude/longitude, and then plot them onto a MapView. I figured out how to do that, but now I'm stuck because I dont know what Canvas to pass when I call the method drawMyLocation().
Here is the MyLocationOverlay class

The way we are retrieving locations from our Android phones is to 1st get a Coarse Location followed by a Fine Location. This is for the case where the user may be inside a building initially and unable to track satellites. After we get our coarse location we transition to a fine location to track satellites. This method has been working fine for several months. We recently upgraded to 1.5 and our mapping application, to my recollection continued to work.For the past couple of days we have not been able to get a coarse location and we are receiving a status message in the onStatusChange callback of.We have re- installed previous versions our code that used 1.1 and we are receiving the same status message of .TEMPORARILY_UNAVAILABLE. Other than the obvious description of the constant, we can find no meaningful information.

Recently all my android devices think they are in Spain when I am at home in Toronto.
I think this was caused when I ran a location spoofing program on only one of my devices, one of the locations I set it to was Spain (among others).
I've tried clearing the data for the Network Location apps, changing the SSID on my router with no luck.
The only way it shows the correct location is when I go outside and run Google maps long enough to get a GPS fix. But when I go back inside I am back in Spain!
The devices this is affectingGalaxy Nexus with my google account
Nexus 7 with my google account
Galaxy S3 with my google account
Galaxy S2 without my google account

I've found bits and pieces of this answer scattered through other posts, but I wanted to record it here for others.How can I simply request the user's GPS and/or Network location and, if they haven't enabled the service, prompt them to do so?

How could I fix the location which appears on the clock on the home screen and serves as weather forecast location? I am not living near a big city listed on the weather location list and when at home, the current location usually is indicated some dozen miles away from my home. This could be a cosmetic problem, but in the Alps (where I am living) weather a short distance away can be quite different from where you are.
Besides that, it would be nice to know the weather at home while beeing abroad.

i've had my phone about 3 weeks now. up until last week, the htc weather widget would update to my current location. when i was home, it would show the town i live in. i also had the google internet option to use my location and this would also work perfectly until last sunday.now, the weather location was stuck on miami no matter where i went (as far north as west palm beach) and the internet shows up 'location unavailable'. i have found out that the gps is picking up where i am in goggle maps but it seems that the cell towers are not as far as weather and internet location are concerned. i have tried all of the obvious settings.i did a factory reset and now my weather says ft lauderdale which is closer to me but still not my town. it does not update (manually either) as i move. the internet location still says location unavailable although for a fleeting minute after the factory reset, it DID locate me....then it was gone so i called verizon, they didn't have a clue. then i took it to the store and it turns out EVERY phone the tech tried in the store had the same problem, including his. he told me it was a google problem and there was nothing he could do about it. i felt if i tried explaining how that would make it a verizon problem as well, it would be a losing battle

I am having problems with the quick search feature. I did a random search for Mcdonalds and a map pulls up that is no where around me. I clicked update location but it says my location is unavailable. I have GPS enabled and my navigation app works just fine.
