On the iPhone, when you hold down the top button and the button on the bottom it takes a snap shot of your screen, I love that feature. Does the droid have it?

View 4 Replies View RelatedI am just looking for opinions, which phone do you think has the better screen (display), the nexus one or the Droid? I guess 2 things to consider are
1. The Droid is 480 x 854 while the nexus one is only 480 x 800 and
2. The nexus one has an AMOLED display.
Now I am not the most tech savvy person so I am not 100% sure what these mean lol all I know is that from what ive heard, #1 goes to the Droid and #2 goes to the nexus. So idk, is it really just a matter of opinion? I own a nexus one and it has a great screen but from what I've seen from the Droid, the droids screen looked a tad better. However that could be due to my limited experience and if I had the Droid for a while, my opinion might change.
Yesterday my Droid 2 got automatically updated to 2.3.20.A955. It worked fine yesterday. I turned it off when I went to bed and now this morning after turning it on, it appears to be functioning except the only screen display I get is the white M (Motorola logo) that normally appears when starting up. I have tried to turn the phone off and on several times, although with no display it's hard to even know if it's happening. So far, nothing.
Edit to add: Well, I took the battery out and put it back in, now it's working. I should have tried it earlier but I didn't. I'll leave the thread up just so people know there is an issue.
Brand new to droid programming, but would love to learn as much as possible, so I finally got my emulator working correctly, I even got a hello world button to work. I'm attempting to make this button display a random number, I've googled this and came up with this code:
Random generator = new Random();
int n = generator.nextInt(n);
I fixed the Random function by including some Random java utility. I'm assuming this code above goes in the .java file of the project, so my button code looks as follows (tested and works):
PopUpText.makeText(v.getContext(), "Hello World",
PopUpText.LENGTH_LONG).show();
I figured I could replace "Hello World" with n to display the number in the box, however the following error is stopping the compile:
The local variable n may not have been initialized
I'd like to have code sample (xml & java) of how I can overlay buttons (any view) into a camera video preview. Of course I'd like real Buttons : no bitmap of the button over a video. I need to keep the clicked event, button pressed/up functionality, etc
Where can I find such Tutorial ?
i have a spinner with an arrayadapter that is dynamically managed. when it gets displayed, the spinner text also displays the radio button. how do i get rid of this radio button?
NOTE: i'm not talking about the radio buttons that appear in the list that is displayed when i select the drop down on the spinner.
here is a pic of what it looks like: SIGH cannot upload image as i don't have 10 pts. so i've found a link: http://www.slashresources.com/android-gui-examples/ scroll down about 1/2 way and find the spinner example on that page. and my spinner looks like the spinner thats grayed out by the list. notice how the drop down arrow is all strecthed and yucky... thats my problem.
Here are the appropriate code snippet... couple of points:
This code is in the constructor of widget which is a subclass of Spinner value is an array of Object instances (passed when the widget gets created) there are no XML resources; all widgets are dynamically created thinking i need to "manipulate" the prompt, i added setPrompt(...) in the constructor and also in the onitemclicked event listener... this had no effect.
Q: what am i missing? seems to me i'm missing some attribute of the Spinner which is causing the radio button to also display in the text part of the spinner.

One thing i absolutely HATE about my Droid INC is the wallpaper is the same for all screens.Can the X display a different wallpaper for each home screen? If not do you know of any Android VZW phones that will?
View 3 Replies View RelatedSome questions regarding locked screen.
1) How do you get the locked screen to show for more than 5 seconds?
2) Where is the clock that is on the box?
3) Is there a way to be able to use the "droid" theme that is shown when you power the phone up?
The gap between the screen and housing, particularly at the bottom, seems to be pretty wide on my phone. i notice at night that light shines through that gap. Can't tell if the gap has gotten any wider. Just wondering if anyone else notices something similar. Seems like a great place for dust to enter the screen. Especially if light can come through there. Doesn't mean it's not sealed, but obviously it's not a super tight fit.

View 4 Replies View RelatedWell, I've been noticing a few more problems with my eris as of late (if you want to know the others look at my post history)I've been unable to get past the lock screen to display sometimes. I just got off the phone with a friend, it was a long call as the phone/battery had heated up a bit. Now, everything with the phone seemed to be okay, I went and pulled up the HTC battery widget and was around 34C. I've seen it get this high before and had no problems. Now, I locked the phone and a few minutes later I tried to unlock it. The unlock screen would display but the touch screen wouldn't not receive any of my input. The Menu button did not work either. I could push the end button time and again and the display wound turn on and off, but no touch input ever worked. I just had to do a battery pull to get into my phone.
I've also been noticing inside TaskPanel that the amount of available memory steadily declines even if no programs are running. I have mostly sense programs ignored and I've included timerriffic and beautiful widgets as they are always running and need to be so they will function. (beautiful widgets I just purchased yesterday and I've had this problem for a week or two) If I do successfully get past the lock screen the phone will be extremely slow and TaskPanel will report something like 20 megs of available memory, with no applications running. If I restart the phone I'm usually fine. I think it is happening around the 13-14 hour mark of my phone being turned on.
I'm assuming something is hogging up my phone and I just can't tell what it is. I don't have very many 3rd party applications installed. They are closed immediately after I'm done with them except for beautiful widgets and timerriffic. I've had timerrific since the 2nd day I've owned my Eris and it's never been a problem (not to say an update didn't hose it)Anyone have similar problems? Anyone think of anything that could be causing this? [side note: I did notice a few weeks back my exchange calendar was freaking out and draining my battery, but deleting and resetting up my exchange email fixed that and it doesn't seem to be a problem now]
My phone was working just fine and randomly the lock button stopped working and the home button brings up the power screen!

View 2 Replies View RelatedSuppose I have something like an alarm activity which launches the alarm through the lock screen, accomplished via
getWindow().addFlags(WindowManager.LayoutParams.FLAG_SHOW_WHEN_LOCKED);
getWindow().addFlags(WindowManager.LayoutParams.FLAG_TURN_SCREEN_ON);
Now, from here I could press the back button to kill the activity, but I also want a press of the lock button to silence the alarm. How would I go about creating a handler for presses of the lock screen button?
