I use http://stackoverflow.com/questions/541966/android-how-do-i-do-a-lazy-load-of-images-in-listview/3068012#3068012 to load images in a ListView and a GridView. It works but the images are loaded form bpttom to top. How to fix that?
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.

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?

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?

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).

I am very new to Android (and Java) originally a C# developer.. and am struggling with the concepts and terminology.
I have been through almost all the tutorials and have decided to start on my first test app.The first part of my app is going to involve using the gallery widget (based on the hello gallery tutorial) to display a load of images. (these images will eventually come from the phones camera, but I will cross that bridge later!) My images are currently stored in the drawable folder in my project.As a first step I want to just have the user click on an image and it pops up full screen, just so I know how to get reference to it, but I am struggling. Evetually I want the user to click an image, then a window/activity(?) will open asking them for a bit of text. This will then be store in sqllite against the image. Code...

Just wondering if its possible to use the built in image viewer to display an image sourced from a database. I'm hoping I can pass the byte[] as an extra to the ACTION_VIEW intent, but can't find any docs on it so far. Alternatively I'll have to roll my own viewer or first write the image out to a file and pass that to the intent.

I am playing around with the Gallery widget.I would like to know how can we get the position of the image on focus in the gallery. For example having several pictures in my gallery, if I tap my finger to the right, pictures will come and go until it stop to one. How one can get the position of this one picture that is currently on focus ?I don't know if I was clear enough, if there is anything you want me to add do not hesitate.

Is there a way to have an image overlaid over another image. For example, I have an instance where I have an imageview and I would like another imageview to take up the same space and appear over the first image. I don't know if there is a way of doing this. I tried putting the second imageview within the first imageview, but that's apparently not allowed in the layout xml files. So is there perhaps a way of doing it with a different layout, such as absolute or frame?
