I'm having some difficulty with drawing a line on a map. I'm basically drawing it etc. but when I select other tab and then come back to the "map tab" the line disappears. How can I prevent that so the line stays there all the time? Please can someone help me to solve this?

I want to draw a straight vertical line on my Android activity, when a button is pressed. Please explain how I can draw the line with a position & length I want.I have a linear layout with vertical orientation. A set of buttons constitute this linear layout. When I press one button, I want a line to appear to the right of these buttons, like dividing the screen halfway - a straight line of width=2dip and height=200dip.
View 1 Replies View RelatedI'v been busy for a long long long time finding out how to draw a line between two (gps) points on the map in HelloMapView but with no luck.Could anyone please tell me how to do so.Suppose I use the HelloMapView which extends MapView. Do I need to use overlays? If so do I have to override the onDraw() method of the overlay and draw a line here? I actually tried these things but with no result.

View 3 Replies View RelatedIn my application the user selects an image. When the ACTION_GET_CONTENT intent is launched it displays the dialog to select one of the available image viewers installed on the device. However I need the built in Gallery app to be chosen because upon selecting an image it launches the screen to crop the image (same thing that comes up when choosing the home screen wallpaper) which only the Gallery chooser offers.
Is it possible to skip this chooser dialog and launch the Gallery automatically? Or at least remove the other options from the list so only Gallery displays?
I would like to give the users of my app the possibility of selecting a language from within the application. All languages are supplied the standard way via the values resource directory. However, I don't want Android to select which resource directory to use but let the user decide instead. Any ideas how to accomplish that? The rationale for this: - some languages are not supported by the Android framework and can not be selected as a locale via the system settings - if you buy a phone in Spain, it will typically not have a system setting for Russian language, if you purchase in Russia, you will have that setting. So a Russian person in Spain would prefer using the Russian language included with the app, but can't access it

View 3 Replies View RelatedI'm trying to modified the way TimePicker works as asked in my question here http://stackoverflow.com/questions/2580216/android-timepicker-minutes-to-15
To be able to do that I need to know if the + and - button was clicked and to disable the input field.
So can I target the elements in a TimePicker? (i.e the + and - button and the input field)?
Also is there anyway to determine if the + or the - button was clicked?

View 2 Replies View RelatedIts me again. I tried the last hours, how to change content of a spinner. ok, lets start from the beginning.
I have three spinners. They all have initial values. The first spinner is the main spinner and the other two spinners depend on the vale chosen in the first one. So i want to update the last two spinners after making a selection in spinner one. *edit: All spinners are on the same activity.
How can i achieve this? My problem is that i can only make changes in the spinners onitemselectadapter but thats a whole new class. I cannot reach the activity where my other spinners are.
Android's messaging app, located in projects/platform/packages/apps/Mms.git has a class called RecipientsEditor. I would like to be able to create MultiAutoCompleteTextView that will filter contacts the same way, to make contact selection easy in my app. using the mms app is cumbersome since it uses internal apis and has everything split across classes.
Has anyone made an easy way to do this?
I have been having a problem with a notification not opening/going to the correct activity when it has been clicked. My notification code (located in a class which extends Service):
Context context = getApplicationContext();
CharSequence contentTitle = "Notification";
CharSequence contentText = "New Notification";
final Notification notifyDetails = new Notification(R.drawable.icon, "Consider yourself notified", System.currentTimeMillis());
Intent notifyIntent = new Intent(context, MainActivity.class);
PendingIntent intent = PendingIntent.getActivity(context, 0,notifyIntent, PendingIntent.FLAG_UPDATE_CURRENT | Notification.FLAG_AUTO_CANCEL);
notifyDetails.setLatestEventInfo(context, contentTitle, contentText, intent);
((NotificationManager)getSystemService(NOTIFICATION_SERVICE)).notify(NOTIFICATION_ID, notifyDetails);
If I click the notification while the application which created the service is open, the notification disappears (due to the FLAG_AUTO_CANCEL) but the activity does not switch. If I click the notification from the home screen, the notification disappears and my app is brought to the front, however it remains on the activity which was open before going to the home screen, instead of going to the main screen. How do I specify the activity that will be pulled up?
I'm displaying the contacts in a Multi-select "Ok, Cancel" dialog box. I've implemented Filterable for the adapter that displays the contacts in the dialog.
