Android :: Rotate An Image On The Entire Screen
Jul 28, 2010
I can't seem to rotate properly an image on the entire screen. The problem is that when the image rotates, you can see the background in some areas. I want the image to fill the screen also when it rotates. Here is the layout.I start the animation in onResume. As I said, the image rotates but there are background areas when it does rotate. I've tried using images much bigger than the screen but still it doesn't do what I want. I don't care that outer regions of the image are not visible. I just want the rotation to fill the screen. I guess ImageView sets its width and height initially and then, when it rotates, it uses those dimensions. Is there a better way to do this?

The ellipse is drawing perfect in moving and zooming cases, but I don't know how to set new points for the ellipse if I rotate the image. this is the code I'm using:
@Override
protected void onDraw(Canvas canvas) {
super.onDraw(canvas);[code].......

I have a HTC Magic (Rogers Canada).And, I see how the Dream (G1) rotates the home screen. can the Magic do that as well? Also, anybody know if it's possible to rotate the screen to the right and not just to the left? Shouldn't the acceleromater detect all the different rotated modes (even upside down?). that'd be cool

I thought it may have been my eyes, when I thought I saw an upside-down Android icon for a contact the other day, on my Android 1.5 device - Samsung Moment. I was playing with contacts just now, and I saw the upside down icon again. Then I was curious, went to see other contacts, and I noticed the Android icon facing right, then facing left in other instances. There is no rhyme or reason as to when the Android icon will change positions, but it is there.

I'm using this camera code to ask the camera to rotate the captured image data... this seems to work on all phones, except the Droid. Has anyone else seen this? The image data is always landscape, however, the native camera app produces portrait images OK. I wonder if the Droid will only respect the new Camera.Parameters.set Rotation() method, but this seems to only be available in sdk level 5?

I need a small help on rotating one image around its center of axis among multiple images which are drawn to canvas in android.
I am loading images to canvas like below.
canvas.drawBitmap(mMachineBackground, 0, 0, null);
canvas.drawBitmap(mMachineRotator, 0, 0, null);
I want to rotate only the second bitmap around its center of axis instead of rotating the entire canvas(which includes first bitmap also).

So through a weird assortment of events i managed to crack the screen on my Eris. But this is the trippy part, I didnt break the glass but the touch sensors underneath. So now i am unable to use the menu or home buttons and the entire left part of my screen and more. I am unable to unlock my device in anyway that i know(menu button, the slider). Is there any other way to unlock it? I now have 11 unread texts and 4 voicemails that I desperately want to view. Oh and I know some of you won't be happy about what I'm about to say but.... I took the leap to the moto droid. I had the chance to get it on a 1 year because I didnt get insurance and I went for it. I will really miss my Eris but the keyboard lag was just killing me.

I have a very large image and I only want to display a section the size of the display (no scaling), and the section should just be the center of the image. Because the image is very large I cannot read the entire image into memory and then crop it. This is what I have so far but it will give OutOfMemory for large images. Also I don't think inSampleSize applies because I want to crop the image, not lower the resolution.
Uri data = getIntent().getData();
Input Stream is = getContentResolver().openInputStream(data);
Bitmap bitmap = BitmapFactory.decodeStream(is, null, null);
Any help would be great?

is it possible to manually rotate the screen or fix the current screen orientation (with a key/button)? because it really annoys me having taken portrait pictures that cannot be viewed (with the media gallery application) in a portrait fashion on the milestone. this is because it always rotates the portrait picture back to landscape when rotating the milestone from landscape to portrait. right now there is no way of properly viewing portrait pictures on the milestone other than tilting your head (holding the milestone landscape and tilting your head along).this cannot be the way it was intended to be, right? or do I have to get a different viewing software which allows you to choose screen orientation? is there such an app?

I'm having trouble with this layout - I need a ScrollView, then a LinearLayout with a button below that:
CODE:........
The scrollview pushes the linear layout under it off the screen. The only way I can get this to work is if I explicitly set the scrollview height in pixels to be less than the total height of the screen, but hardcoding a height isn't going to work on different devices. How can I do this?

Is there an app to get a landscape virtual keyboard that is shorter? The text box above the kb is strangely huge and some if not all of that space should just show the page you are entering the text into.
If it's ebuddy, it should show one line of text and let you see the last message sent to you. If it's on a web page, then omit the text box entirely, we can read what we are typing into the boxes on the page last I checked. Anyone know of anything? It's a major annoyance for me.

I would like to use an <include /> in my XML file to add a layout below a MapView(or any other greedy layout). I have been trying for a few hours now, and no luck so far. I was hoping someone could give me a hand.
Here is what my XML looks like now:
CODE:...................
Optimally, the include could be any sort of other layout. The goal here is to have the Google map on the top, and then have the included layout below it. If I include the content in the layout, such as replacing the <include /> tag with a <TextView /> then that works correctly, so I am thinking I am mis-using the include. A trip to hierarchy viewer shows that the included layout has no height. I have tried putting the include first, and using a RelativeLayout to position the map above the included layout, but I could not get that to work correctly (the included layout took the entire screen space, even though I explicitly said layout_height='wrap_content'

Sometimes the screen auto-rotates when I don't want it to if I angle the phone slightly. I am constantly toggling it on and off. To do so of course, I have to go into settings, then display. Does anyone know of an app that I can add the toggle switch as a shortcut on my desktop? It is kind of a pain to go through the settings each and every time. I would much rather just hit it easily on my homescreen.

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!

Last night, I noticed there was a pink blob down in the lower left corner of the screen, it bothered me but wasnt too bad, the rest of the screen looked normal. I went to bed, and when I woke up this morning the ENTIRE screen was pink - apart from that little blob which is now black. The colours are completely ruined, red and white is now pink and it doesnt show yellow at all, the messaging icon etc. is now a dark orange. I just bought the phone on thursday so this is a major problem for me, it's not exactly cheap.
The problem is that I'm from Norway and the Nexus isnt sold here, I bought it from a guy who had bought a lot in the US and was reselling, through our version of eBay. The box was unopened and everything, so it had not been tampered with. The problem is that they maybe won't let me return it because of this, and if I want help I'd have to ship it to the US, no help to get for it here.
