I have a png-picture in ImageView rotatedimage = new ImageView ()
Is there a better way to rotate it in changing directions than the following way? There I have to create a new picture for every new rotating angle and add it to the layout...

I'm having Android code to move, zooming and rotation image. And it working perfect. Now I want to set ellipse on the image and changing it place upon image changes. 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 rotate image using setImageMatrix() function. I first use getImageMatrix() function to get matrix then i use matrix.postRotate (90). Rotation works fine. But it rotates around top/left corner of image. i want to change that pivot point to center of the image. how can I do that?
View 3 Replies View RelatedI 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?

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.

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?

View 1 Replies View RelatedI 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).
Does anyone know of an animation/method that can rotate an image around smoothly to face a point, such as where the user is touching?
View 1 Replies View RelatedI'm trying to figure out exactly how to interpret the rotation angles produced by a Sensor Event for Sensor.TYPE_ORIENTATION. Unfortunately, the documentation (http://developer.android.com/reference/android/ hardware/Sensor Event.html#values) doesn't give a complete definition of it. It defines what the axes are, but doesn't specify what order the three rotations are applied in, nor whether the later rotations are around transformed or untransformed axes. Without knowing that, it's impossible to know what the actual rotation is that's being described.

View 6 Replies View RelatedAs 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!

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?

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

Bonus Question: Can I use a loading animation in a image view while the real image is loaded? Right now it's just a default image.
It will be helpful if any one can help me out in understanding the concept of radio,flash,system image in android mobile device. Also why are they required? and what is their role in Device?

View 4 Replies View RelatedI am extending the normal android.widget.ProgressBar.This rotates it fine, however I am having alot of sizing issues. It seems as though I have to set the width and the height of the control to be the same thing or else I run into alot of clipping issues. Basically, I want to have a progress bar that, once rotated, is 50dip wide and fills the screen vertically. Can anyone think of a way to do this? Also, it doesn't seem to be actually drawing the progress properly, but I will revisit that once I get the clipping sorted out.

View 2 Replies View RelatedI am getting error when I rotate the device (it was HTC with Verizon):
The application My App (process com.mycompany.android) has
stopped unexpectadly. Please try again.
So, I think I need to code for this issue. In order words, when rotate the device from landscape to portable or from portable to landscape, application needs to catch this event.
Is it right ?
How to make it ? What is wrong here ?
Is it possible to test on the emulator ?
It's actually really easy, and you don't need to use animations. I did something like this recently by using a wrapper layout that adjusts the Canvas and any MotionEvents. (You could also use this approach rotate the entire layout to any arbitrary angle.) I think romainguy told me to use Canvas.concat(mForward) instead of setMatrix(), but I haven't updated the code in awhile...................

View 3 Replies View RelatedI have a layout with an image on it (embedded in an ImageView). I need to rotate the image (let's say) 90 degrees CCW. I've written code to animate the image rotating. The image smoothly rotates 90 degrees, but then snaps back to its original state. This is what the Android documentation says will happen after an animation completes. Presumably, on the notification that the animation has ended, I'm supposed to transform the ImageView (or the underlying drawable), and possibly invalidate it to trigger a redraw. All well and good, except that I can't find a way to do it, and I can't find any examples of anyone else doing it. I tried using getImageMatix/setImageMatrix on mImageView, with no apparent effect. There are subclasses of Drawable that will rotate an image, but there is no setDrawable() method on ImageView, so I don't see how to use one.
