I have the beginnings of an app that will eventually comprise of three screens. I want to allow the user to move through the screens by flicking the current screen.
The screens should be positioned horizontally: 1 - 2 - 3
So, a flick from right to left should move from 1 to 2, a flick from left to right should move from 3 to 2 and 2 should be able to move to pages 1 and 3 respectively.I believe this is called SwipeView but cannot find any clear instructions on how to implement this.
The default behavior of an activity when BACK softkey is pressed is, GO BACK TO PREVIOUS ACTIVITY. If some the same activity is waiting for some response from server or some data updation is going on and then press BACK, I want to wait on the same screen till the current task is completely processed and then move out to the previous activity.

After implementing some Android Apps, including several Map activities, I try to refresh the activity when the GPS listener's onLocationChanged() mehtod is called. I have no idea how to tell the map activity to refresh on its own and display the new coords. the coords to store will have to be in global values, so that the location listener will have access to it. In my sample GPS-class (see code below) I just changed the text of a text view....but how to do that in map view?

View 1 Replies View Relatedis it possible to manually rotate the screen or fix the current screen orientation (with a key/button)? because it really annoys me having taken portrait pictures that cannot be viewed (with the media gallery application) in a portrait fashion on the milestone. this is because it always rotates the portrait picture back to landscape when rotating the milestone from landscape to portrait. right now there is no way of properly viewing portrait pictures on the milestone other than tilting your head (holding the milestone landscape and tilting your head along).this cannot be the way it was intended to be, right? or do I have to get a different viewing software which allows you to choose screen orientation? is there such an app?

How would i go about doing this? (i have no programming experience)

I want to make an infinite Ruler App, so I need to dynamically add and remove view when the view is flipping, but how and where can I find out which childview is shown on the current device screen, so I can add or remove the correct view when I get that childview changed notify?

E.g after launching uiEditContactActivity,how can I identify the views [ several fields, buttons etc] part of that screen.

Is there way to dump the current screen to a bitmap in Android?
And what about dump screen of other applications? For example, running a service background, the foreground app could send an intent to start the service, and capture the current screen and save as a bitmap.
I have an NoContentViewActivity which has no Content View (i.e. I did not call setContentView() in the onCreate of my Activity).
My question is how can I keep the content view of the launching activity on the screen? Right now, I am getting a blank screen whenever I launch NoContentViewActivity? I want the content view of the launching activity (the activity which start the NoContentViewActivity) to show on the screen.
I need to launch a service running in the background,that should record what's on the current screen for say about 10 sec.. i should able to save it in a file or on any storage device and later i should able to retrieve it also..

Android 4.0.3
OpenCV 2.4.2
Samsung Galaxy S2
The face-detection example (from the opencv 2.4.2) is working perfectly. But now, I would like to create a custom layout and actually work with just the data extracted from face detection and build a game on it. Not necessarily having the FdView surface taking the entire screen.
I have done these modifications below, but just a black screen is displayed. Nothing appears on the screen.
Changed the BaseLoaderCallback in FdActivity.java
Code:
//EXPERIMENT
setContentView(R.layout.fd);
FdView surface = (FdView) (findViewById(R.id.FdView));[code]....
Is there a quick way to change the order of the screens? For example, I'd like to move my current screen 7 and make it screen 2.

When one wants to publish his App on the Android Market he can upload up to two screenshots of his app. I would like to take these screenshots with my current device (Motorola Droid) that I'm using to test the application.
There are some Apps on the Android Market that allow you to take screenshots, but you have to root your phone, which I dont want to. There are related topics within stackoverflow where people want to take screenshots out of there code (here). However I just want to take screenshots of my running app with the current device, which is connected via USB to my computer; I'm developing via Eclipse, so there should be a way to tell your running device that it should take a screenshot via the sdk, right?
I am wondering if you guys have found a way to send or receive mms on your heroes and what version of android yours is running. Mine is running 1.5 and is the round hero, not the newest one. I also cannot find a place anywhere to send mms. Also, how do I snap a picture of my current screen, or do I need an app for that?
View 10 Replies View RelatedI recently got the M8 upgrading from the Galaxy Nexus. I am a design student, and I HATE, I mean HATE the current clock set up with that damn weather icon and how it all looks uneven. Are there any widgets/apps or anything which I can change this?
On my galaxy: [URL]
On my one: [URL]
Is there anyway I can change my current clock or SOMETHING. I do know that I can add a new widget page and have a new clock, but I can't make this my default lockscreen. Sliding across on the lockscreen seems pointless to me - i want this visible when i double tap my phone.
I tap weather icon, get current location no city name and the weather info, I then tap "+" hit my location and it finds my city Corning NY, I add this to the weather app, I close out and hit weather app again and now I have to locations, the one that says current location and the one that says Corning NY, both weather datas are the same. My question is how to I delete or get rid of the current location weather data screen and have only the Corning NY screen when I open the weather app? The data for both is the same but I don't want 2 locations(one named) for the same data.
