I need to rotate an ImageView by a few degrees. I'm doing this by subclassing ImageView and overloading onDraw(). code...
The problem is that the image that results shows a bunch of jaggies.
How can I antialias an ImageView that I need to rotate in order to eliminate jaggies? Is there a better way to do this?

Is there a way to permanently disable anti-aliasing? I find anti-aliasing a little irritating. It simply smooths out images which essentially strips out details. I've never liked it.
I find myself slowly scrolling back and forth in the browser to disable the anti-aliasing so that the images I view are more defined.
It seems most poeple complained that the anti-aliasing slowed down performance but that isn't my issues. I simply don't like how it degrades an image.
In my application I want to be able to rotate a view programmatically rather than via XML. I can easily create a <rotate/> drawable that references my Drawable, but I can not figure out how to do the same thing in Java. The problem is that many drawables in my scene can be displayed either vertically or horizontally and I do not want to have to create a separate rotate drawable for every drawable in my scene.
One thought I had was to instantiate a RotateDrawable in Java and then use that as the background for my view, but it does not appear that you can set the rotation of a RotateDrawable instantiated this way (you have to feed it XML to get it to be at all useful from what I can tell).
Another thought I had was to rotate the canvas, but I would like to be able to use the drawables as view backgrounds and I do not see a way to rotate the canvas before the background of a view is drawn and then revert it afterwards.
I also looked into creating some generic rotate drawable and then perhaps changing the drawable that it applies to, but that lead no where.
So, does anyone have any ideas about how I can rotate a drawable in code and then use that rotated drawable as a background?
I wanna set the ADB_ENABLED and USB_MASS_STORAGE_ENABLED option automatically in my App.
so i add below statement in my App(Activity).
---------------------- Settings.Secure.putInt(getContentResolver(), Settings.Secure.ADB_ENABLED, 0);
or
Settings.Secure.putInt(getContentResolver(), Settings.Secure.ADB_ENABLED, 1); ----------------------
and add below statement in my App(manifest).
---------------------- .... </application> <uses-permission android:name="android.permission.WRITE_SETTINGS" /> <uses-permission android:name="android.permission.WRITE_SECURE_SETTINGS" /> .... ----------------------
but some exception are occured in runtime like below.
---------------------- Uncaught hander: thread main exiting due to uncaught exception. java.lang.SecurityException: Permission denial: writing to secure settings requires android.permission.WRITE_SECURE_SETTINGS ... ----------------------
How i can use ADB_ENABLED and USB_MASS_STORAGE_ENABLED in my App?
When using border-radius on my android emulator I am seeing ugliness like this:
Is there anyway to get Android to display rounded corners via -webkit-border-radius in a more pleasing way? Most modern desktop browsers and Mobile Safari seem to antialias their corners, but not Android's renderer.
I'm really hoping I don't have to do this with images, and there is some awesome trick to get pretty corners with only a border radius css declaration.
As we know, we can rotate a bitmap through 2 ways. The 1st way is: Matrix mt = new Matrix(); mt. postRotate (degree);Bitmap bitmap = CreateBitmap(src, 0, 0, w, h, mt, true); canvs.drawBitmap(bitmap, 0, 0, paint); In this way, we always need create new bitmap for every rotation, it is not good way for high performance game or app.The 2nd way is: canvas.save(); canvas.rotate(degree); canvas.drawBitmap(bitmap, 0, 0, paint); canvas.restore();In this way, we avoid creating new bitmap frequently, but the rotation bitmap is distortion, the bitmap quality is worse than first way.So, Is there 3rd way to rotate bitmap with high performance and good quality? Your any comments are really appreciated!

View 4 Replies View RelatedI just bought the Nexus One unlocked for AT&T and really like it. 1 wierd thing is that when I rotate the phone counter clockwise, the screen goes to landscape just fine; but when I rotate it clockwise it does not go to landscape "the other way". And, if I'm holding the phone 'normally' and rotate it 180 degrees ('upside down') it doesn't follow.My youngest daughter delights in telling me that her iPhone does this with no problem. What's up with that?

View 6 Replies View RelatedLast night I downloaded antivirus free by droidSecurity inc.I ran a scan and it said I had something suspicious but would not allow me to view any details. Eh lame, I removed the app and jumped into bed.Today I was out driving around and got a warning my internal Phone memory was low. I took a look and it said 150 MB free.so I rebooted the phone and maybe I was being dumb because I thought you could cancel the SIM password and use the device as a PDA with no access to make phone calls.Anyhow I restored my clockwork recovery nandroid backup from a couple of days ago and now things seem better. Phone has 0.9 GB free.Are there any good applications to help manage the available memory on the phone?
View 4 Replies View RelatedI subscribe to the church of not using a task killer but what I really would like is an app that I can select programs I don't want android to kill.
An example of why I want this: theres 3 to 4 websites I view for the most part on my phone. I like to open my browser and get it all set up in tabs on Dolphin. However, if I don't use it for while, I re-open the browser to find it had been closed and I have to repeat.
I'd use this in conjunction with the app that monitors CPU use (forgot what it was) and gives a notification if an app rises over a customized threshold in case the app started getting too hungry.
Seriously? Is that really necessary?

Of course if it used augmented reality to place the planes on the camera view that would be even better!
Does anything like this exist out there?
I know that there are a lot of anti-theft apps, but from what I understand they are completely useless if the thief restores factory settings, deleting the app. I would like an anti-theft app integrated in the ROM, so it will survive a factory reset and detect a thief, as long as he doesn't flash another ROM!

View 21 Replies View RelatedInstalled my clarivue last night. It was really easy to install. This really helps with visibility outside, the screen isn't reflective like a mirror anymore. The touch screen doesn't feel as good as naked, but it repels fingerprints so I think it's worth the trade off. Excuse the dust.
