Android :: To Draw A Vertical Line / When A Button Is Pressed?
Sep 28, 2010
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.

I recently noticed that on my EVO screen, there is a very small blue vertical line running from the top to the bottom of the screen. Its noticeable sometimes when im searching the web or with dark backgrounds.
Do you think I should return it? Or is there a program that can fix stuck pixels...

I have a green line (Vertically) about a 1/3 of the way from center to the right. I got my phone when I woke up this morning and unplugged it. I then went back to sleep for 30 minutes, when I awoke I turned on my phone. For a few seconds it was fine but after about 30-40 seconds the line appeared with a flickering gesture, then a consistent line.
information :
When I take a screen shot it is not there.
I factory reset my phone still no resolve.
It shows up on boot up.
I haven't dropped my phone, even once.
it is a GSM unlock so I cannot return it to the manufacturer.
I do a lot on my phone including gaming, social networking, and watching tv shows/ movies.

This problem happened few hours before i rooted my pad. Well the problem is a vertical green line that appeared in my screen and dont go off. I tried to use stuck pixel solutions and a factory reset (I didn't tried to put back in stock rom, I don't know how to do that).
The line is very perceptive on a pink background, but completely hide by a green background.

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'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.

This is really frustrating, I am trying to get a carriage return drawn in my custom view and nothing is working. I have tried 'System.getProperty("line.separator")' but that makes it say null and I have tried '
' and '
' and those just both draw a little square. I am using the canvas.drawText meathod.

Does anyone know how to tell when the headset button is being pressed? I'd like to support the usb headsets and possibly bluetooth headsets. My app is a media player and ideally, I could register it somewhere so that if no app that uses the headset button has focus it button press would act as a play/pause command in my app. If the phone is ringing or a call is in progress, I'd like to be sensitive to that and let the button do what it normally does: pickup and hang up calls. we've been trying to chase the button down using this: Intent Filter headset Filter = new Intent Filter (Intent.ACTION_HEADSET_PLUG); headset Filter.addAction ("android.intent.action.HEADSET_STATE_CHANGED"); headsetFilter.addAction("android.bluetooth.intent.HEADSET_STATE"); headset Filter.addAction ("android.bluetooth.intent.HEADSET_STATE_CHANGED"); headset Filter.addAction ("android.bluetooth.intent.action.MODE_CHANGED"); headsetFilter.addAction("android.intent.action.MODE_CHANGED");

Is there a way I could get the color that is used when a button is pressed? I know that the button uses a default selector xml that consists of the pressed image. But, I am having some custom buttons for which I want it to be close to the default image used for pressed state.

i have an app widget that has a couple of buttons on it, and in my onUpdate() call, I am hooking up the buttons to do something when you press them
RemoteViews remoteViews = new RemoteViews(context.getPackageName (), R.layout.appwidget); remoteViews.setOnClickPendingIntent(R.id.Button1, button1PendingIntent); remoteViews.setOnClickPendingIntent(R.id.Button2, button2PendingIntent);
The problem is that when I click on button2, it sends the button1 pending intent. i think that's because it's reusing the pending intent. http://groups.google.com/group/android-developers/browse_thread/threa. "If the creating application later re-retrieves the same kind of PendingIntent (same operation, same Intent action, data, categories, and components, and same flags), it will receive a PendingIntent representing the same token if that is still valid, and can thus call cancel() to remove it." So then the question is, how do I communicate which button was pressed?

I want to display the text for some buttons vertically "down the screen" instead of horizontally. I don't want the orientation of the letters to change just the direction in which the letters are printed. Is there any way to achieve this, other than creatng a drawable that has the letters in this format and using it as a background? I guess I'd need to center the letters horizontally as well.

I have a BroadcastReceiver that receives SCREEN_ON. If the screen came on because the user pressed a button, I want to do something. However, if the screen was turned on by an app (e.g., alarm clock going off or SMS popup), then I don't want to do anything. Anyone know how I can differentiate between the two cases?

I'm using Eclipse to write the android application.
I've added some standard buttons from the Form Widgets tab and successfully got them opening new windows which display additional buttons.
I would like the button that was pressed, to change appearance and continue to look pressed in after it is selected.

I have an activity that contains several user editable items (an EditText field, RatingBar, etc). I'd like to prompt the user if the back/home button is pressed and changes have been made that have not yet been saved. After reading through the android documentation, it seems like this piece of code should go in the onPause method. I've tried putting an AlertDialog in the onPause however the dialog gets shown and then immediately tears down because nothing is there to block the pause from completing.
