I am displaying images and some text in a list view with an adapter. The images are pulled from the web, then cached locally and displayed. The images are already small (60px square), and I know their size, so I'm using the advice from here suggesting I use setImageURI instead of decoding the bitmap. The class that does the work is a modified version of Fedor's ImageLoader
The code attaches a stub drawable to the ImageView until the desired image is downloaded from the web, then loads the cached file from the sdcard. In Android 2.2 this works just fine. It's fast, and I don't get OOM crashes. On 2.1, though, I get the following error:
CODE:...............

Can you make an ImageView load an image from a remote server through the ImageView.setImageURI(URI uri) method?

I'm using ImageView.setImageURI() to render an image that has been previously downloaded from the Internet. It works fine, but I haven't understood whether the call is blocking or not. In my code, I've implemented a background thread to download the bits, in the meantime a placeholder is rendered, and as soon as a download is complete, setImageURI() is called. This approach is used both for a Gallery with thumbnails and for a single, large rendered with ImageView. The thing is working, but I see that the application freezes for a while when a download has been completed and setImageURI() is called. Which make me wonders whether I'm using it properly.
For the record, I know that the images I'm downloading are larger than I need (at least initially); that is, they are much larger than the thumbnail and the large viewer. Since images, once downloaded, are stored locally forever, I should probably create some smaller-size previews in background and then pass them to Gallery and ImageView? Would that make the UI really more responsive?

I'm having a problem with setImageURI on my ImageView objects. I was using setimageResource(R.drawable.x), which was working fine, but now I'm trying to change over to using URIs so that I can be more flexible about my image source (not constrained to pre-packaged images).
I'm using ImageView.setImageURI(uri), where uri is (for example android.resource://com.example.hellogridview/2130837520, which I created by doing Uri.pars ("android.resource:// com.example.hellogridview/" + R.drawable.x). I took this method from my MediaPlayer, where I created URIs for R.raw wav files from this path.
It's not throwing any errors that I can see, but it's just displaying blank images. The images are ~150px each way and I'm displaying them about half size - would that cause a problem?

I have a view that I am drawing to a bitmap, saving to disk and then putting in an ImageView via setImageURI. However, when the image is displayed in the ImageView it is not being shown at the correct size. It is about 1/3 smaller than it should be. I'm guessing that this is a density issue, but I can't figure out what's going wrong (my emulator is WVGA).

I have a gridView generated using BaseAdaptor. (and implementing methods getView() , getCount() ,...) My problem is that i want to specify a drwable image for each ImageView created using BaseAdaptor.
i tried this line: myBaseAdapterInstance.getView(i, null, gridview).setImageDrawable(R.drawable.myimage);
where i is the position of the ImageView that i want.
But myImage isnt displayed on the gridView.

I have an ImageView object that I'm setting the android:src="@drawable/some_xml_file" instead of a standard png and it seems to not always render the drawable, as you can see in the first row here (it also happens intermittently in other rows as well):
I've tried setting the src & the background property but they both have the same effect. the source code from my list view row item is this:
CODE:...............
Then my res/drawable/action_box.xml is this:

I'm trying to add a drawable to a layout, using an ImageView, but the drawable doesn't maintain its size and is rendered at 1dp x 1dp. I've called ImageView.setAdjustViewBounds as per the android documentation but this doesn't seem to help. The Drawable is only visible when the ImageView's height and width are set and the drawable is then rendered at those dimensions.

I would like to be able to alter the size of some of my ImageViews based on what Drawable they are showing. I've not yet decided on whether I'll get them to read the new dimensions from the Drawable or if I will just have an array/enum storing the heights of these, but what I need help with is the actual changing of the ImageView size.Which of the many many function for altering sizes of things should I be using to change the size of an ImageView while still retaining it's relative positioning in the RelativeLayout it is a part of? I can't work out if I should be changing the bounds of the Drawable or if I should be redefining the LayoutParams of the ImageView or some other method altogether. The drawables are always going to be the same width, but their height will change depending on what is in each tile of a map (which this is rendering).

I had this problem in 2.1v2, I installed v3, and it first, all was well, then yesterday I noticed the same thing...none of my custom set ring tones are being used. phone always rings with the system default.
I can change that, and it rings that tone, but any I assign to a contact don't work.
I haven't installed any ring tone managers or anything, I can't think of what would be messing with it, but it is friggin annoying!

I'm trying to do the following thing without success:
ImageView imgView=(ImageView)findViewById(R.id.imgView); Uri imgUri=Uri.parse("android.resource:// my.package.name/"+R.drawable.image); imageView.setImageURI(imgUri)
I'm stuck, because the imageView just shows nothing. how I can get an Uri (that I can use as ImageView source) from a local resource? which kind of Uri are accepted for the ImageView? IMHO, this topic lacks of documentation.

I want to display pictures into an ImageSwitcher and change image every 3 seconds. I instanciate a Thread that call the setImageURI(URI) and I schedule it every 3 seconds. It does not update the view and I don't know how to do it. If I call the same code that call the setImageURI() from the OnClickListener of the view it works! Do you know why and how can I make it work?

I am running into a very weird thing. I have an ImageView, and when I call setImageURI with an image, it seems to change the size of the image view.
CODE:..............
The default image is 195 x 195, i am trying to set the image to be 200 x 200, after setting the image using setImageURI, i get the dimensions back and it says it's 48 x 48.
I have tried a bunch of different android:scaleType parameters, and I couldn't find anything that worked.
I also tried explicitly setting the size (layout_width="200px") and it seems to work.

I created an application that starts a service. This service is expected to run in background. This service has to access the Location. I am currently unable to do so I have given permission to my Manifest file I think the issue is that the application has the permission, but the Service does not ! What happens is that the service keeps running even if the application is stopped .Does the Service need special / different permissions ? How do I assign permissions to Service ( my service class extends : Service).

I've written an Intent which selects a photo from the gallery. The idea is that the image chosen is received within the onActivityResult() method. On the emulator, I have no images, and it simply says "No media found". How do I assign images which are picked up within the emulator, so that I have something to choose from?

I tried Button Shortcut to remap the search soft key for use with VLingo, and no dice. I got the option to set VLingo as my default on that long press once, and I did, but it just goes to the standard Google Voice search still. No option offered anymore at all. Tried clearing Voice Search "defaults" under application settings and still nothing.

Please be kind, i have tried searching before posting and i seem to be as good as a chocolate fire guard. I have the samsung galaxy s and i installed hand cent sms (or something like that) which was good when it didn't freeze. My problem is, now that i have installed it i am now no longer able to assign a custom text alert as i had before, i have created a folder in the root and when i go to messages, settings, select ring tone i have the ones that came with the phone, plus option of default ring tone, can anyone help this stupid individual out. Also while your reading this novel and thinking "you really are useless" Is there anyway to find out WHEN people have sent there texts, it only shows the time it arrived.
