• Converting a view to Bitmap without displaying it in Android?

  - by sunil

  Hi, I will try to explain what exactly I need to do. I have 3 separate screens say A,B,C. There is another screen called say HomeScreen where all the 3 screens bitmap should be displayed in Gallery view and the user can select in which view does he wants to go. I have been able to get the Bitmaps of all the 3 screens and display it in Gallery view by placing all the code in HomeScreen Activity only. Now, this has complicated the code a lot and I will like to simplify it. So, can I call another Activity from HomeScreen and do not display it and just get the Bitmap of that screen. For example, say I just call HomeScreen and it calls Activity A,B,C and none of the Activities from A,B,C are displayed. It just gives the Bitmap of that screen by getDrawingCache(). And then we can display those bitmaps in Gallery view in HomeScreen. I hope I have explained the problem very clearly. Please let me know if this is actually possible. Regards Sunil

• Is there a view for inputing integers in Android?

  - by J. Pablo Fernández

  I'm looking for something like the individual parts of the date picker dialog. A view that allows you to input integers (and only integers) that you can limit (between 1 and 10 for example), where you can use the keyboard or the arrows in the view itself. Does it exists? It is for a dialog. A ready-made dialog to request an integer would also help.

• In Android, does _id have to be present in any table created?

  - by Andy

  I am trying to create a table to only has a foreign key, not a primary key. I am getting this error: java.lang.IllegalArgumentException: column '_id' does not exist I read a tutorial that the primary key must be _id, with no explanation. And that is fine. But what if I do not want a primary key! What if I only want a foreign key. I am assuming this is where my problem lies. The schemas below are what I have. But the third one is where I assume this is coming from. database.execSQL("CREATE TABLE events (" + "_id INTEGER PRIMARY KEY, event_name TEXT" + ")"); database.execSQL("CREATE TABLE reminders(_id INTEGER PRIMARY KEY, event_name TEXT" + ")"); database.execSQL("CREATE TABLE events_info (_id INTEGER, event_name TEXT, all_day INTEGER, " + "start_date INTEGER, start_time INTEGER, end_date INTEGER, end_time INTEGER," + " location TEXT, reminder_id INTEGER, notes TEXT, repeat TEXT," + "FOREIGN KEY(_id) REFERENCES events(_id), FOREIGN KEY(reminder_id) REFERENCES reminders(_id))" );

• Is there any way to see the diff on a file between two different Android releases?

  - by BenIOs

  It would be really nice if there is some easy way to see what have changed in a certain class (or other file) between two releases (1.6 & 2.1 for example). Does anyone know how to do this? A way to do it online would be great but downloading the code and checking offline would be ok as well.

• Is it possible in Android Market to delete an existing FREE app and reupload it again as a PAY app?

  - by watcherFR

  I have an app I am offering for free for now. At some point, I want to be able to change it to a pay app. The market doesn't allow a free app to become for-pay and doesn't allow for-pay apps to be priced at 0$. So is it possible to just delete the original app and then reupload it as a for-pay app ? It's okay in my case if users aren't notified of updates.

• [Android] How to launch an Activity without a UI?

  - by fjmustak

  Is it in any way possible to launch an activity from the main function without having a UI? i.e. is there a way to create a sort of "wrapper" around another activity, i.e. by launching the main activity, it takes you to another activity automatically. If that is not possible, is there a way to remove the main activity from the stack so that clicking the back button does not take you to a blank UI? Here's an example of what I'm trying to do: public class WrapperActivity extends Activity { /** Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); final Intent intent = new Intent(Intent.ACTION_DIAL, Uri.parse("tel:555-1212")); startActivity(intent); } }

• Why is my input textbox extending outside margins in BlackBerry and Android, but not iOS?

  - by Dallas

  I have an input field that is extending well beyond the rest of the page, but as the question alludes to, it appears fine in iOS. I am wondering if anyone has run into this issue. My search button, which in iOS is on the right of the search textbox, actually wraps to the next "line" on the other two platforms. I am not using a table, just inside a div, and the CSS isn't doing anything fancy. Any ideas?

• ScrollBall press events while screen is off on an Android device.

  - by stolksdorf

  I'm writing a quick music player for myself on my Nexus One and really want to add the feature of being able to switch to the next song without removing it from it's case, ie. by pressing the scrollball through the sleeve. I've scoured many resources and... Haven't found a decently easy way to listen to key press events while the screen is off. Can't seem to even get scrollball press events to work. I've tried using a broadcastreciever listening for the Dpad_center intent, but it doesn't seem to function properly. I'm not looking for someone to write the code for me, but if you have successfully done either of these things, any insight on techniques or resources would be amazing. Thanks in advance!
