Is there any way for an Android application to retrieve some sort of Collection object that contains references to all of the GUI elements which are currently on the phone's screen? This could be very useful for testing purposes and so on. If I have overlooked a well-known class or library, please let me know.

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.

How can I determine if the current time is between two other time objects?
For example: current: 15:23, startTime: 22:00, endTime: 06:00. So the current time is not between this two other times, but this "23:47" is.
*I don't care about the date, only the time
I tried to do it like this:
Code:
Time startTime = getStartTime();
Time endTime = getEndTime();
Calendar c = Calendar.getInstance();
Time now = new Time(c.getTimeInMillis());
[Code]...
but it dosen't work well. their aren't any errors but it just dosen't work.
To be more precise the problem is that 15:35.after(22:00) return true... and I don't know why. I think that the problem is something with the dates but I don't know what
The FAQ mentions a method of passing objects around activities. (It is not clear to me): "A HashMap of WeakReferences to Objects. You can also use a HashMap of WeakReferences to Objects with Long keys. When an activity wants to pass an object to another activity, it simply puts the object in the map and sends the key (which is a unique Long based on a counter or time stamp) to the recipient activity via intent extras. The recipient activity retrieves the object using this key.".................
View 7 Replies View RelatedI have an application that have a Google map on Google Android 1.5 since we have been working on the application for a long time, we are not in stage of upgrading to the newest framework, so we are using 1.5. Now, I have map locations that are dynamically generated and drawn on the map at run-time to visualize some streams, Up to this point the application is working fine, Now my problem is that I am trying to filter the objects ( addresses) to visualize only the on-screen ones. I do NOT want to visualize the addresses that are off-screen. The way I am trying to do this is to check the screen-coordinates of each object (address) before visualizing it, then it the coordinates (x,y) more than (0,0) and less than (320, 460). I should visualize it. I am trying to use this approach, but it is not working for some reasons, I have tried many posts but could not understand why, there must be something missing somewhere that I am not aware of.
View 11 Replies View RelatedI'm using textview objects to hold labels such as Score, Level etc on my game screen but they don't seem to be displayed where I want them to be. I understand about view hierarchies (parents, children) and am using the gravity tags in the XML layout file but it doesn't seem to have any effect. Could someone just quickly provide a guide to positioning a textview object on the screen, and also linking it in the code so that its contents can be pro grammatically controlled (I believe this would by done via =(TextView) findViewById(r.id.resourcename))? Code...

View 2 Replies View RelatedI am finding that performance degrades after one or more screen rotations, and I presume that this is likely to be because an App's main Activity is destroyed and recreated each time the screen is rotated and that my app must be leaking memory when that happens.I have read that, contrary to what one might expect, not all the objects created by an app's main Activity (or in classes called by that Activity) are destroyed when the activity is destroyed. Specifically, I think I have read (although I can't now find where) that if the View uses a large bitmap member object then the Activity's onDestroy() method should be over-ridden and the bitmap should be explicitly recycled.Are there other objects that need to be destroyed or removed when the Activity is destroyed? What about Listeners? Is there a comprehensive tutorial or guide on this subject?

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?

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..

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.

View 10 Replies View RelatedI 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.
I 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.

View 1 Replies View RelatedIs there a way to pass an Array List of objects between activities? The myObject implements Parcelable and I'm able to successfully pass the objects around individually, but that means I need to have an exact amount of "myObjects" coded. I want this to dynamically grow/shrink by what the user does with the app. I have seen some posts on the web about doing:
Activity A
ArrayList<myObject> myObjArray = new ArrayList<myObject>();
Then when passing this into the intent I would use:
intent.putParcelableArrayListExtra("myObjArray", myObjArray);
Activity B
ArrayList<myObject> myObjArray = new ArrayList<myObject>();
Bundle extras = getIntent().getExtras(); myObjArray = extras.getParcelableArray("myObjArray");
However, the myObjArray always gets filled with "null". How can I achieve this?
