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.
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?

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.

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?

View 2 Replies View RelatedI have ported the Android to a x86 platform. And i want to detect the USB plug-in.But follow the information about the android.intent.action.MEDIA_MOUNTED in the SDK's DOC, i can't receive the event of the USB's plug-in. i have checked my code and it can receive the other event ( ps:intent action) .
Besides, in the CLI, i could mount the USB device to /sdcard but it couldn't mount automatically. have seen some source code about the mount and mountlistener and it should be effective. my SDK's version is 1.5.
I would like to have my code run slightly differently when running on the emulator than when running on a device. (For example, using 10.0.2.2 instead of a public URL to run against a development server automatically.) What is the best way to detect when an Android application is running in the emulator?
View 9 Replies View RelatedI want to incorporate some Accelerometer code into a Android application im working and want to see if this is possible. Basically what I need is for the code to detect car acceleration motion. I am not wanting to determine speed with the code but just distinguish if the phone is in a car and has accelerated motion (Hence the car is moving for the first time). I have gone through many different accelerometer applications to see if this motion produces a viable profile to go off of and it appears it does. Just looking for something that popups a "Hello World" dialog when it detects your in the car and its moving for the first time down the street. Any help would be appreciated and a simple yes or no its possible would work. I would also be interested in compensating anyone that is capable of doing this as well.
View 2 Replies View RelatedI need to implement HorizontalScrollView which is scrolled to predefined positions (similar to Home behaviour). It works with slow gestures, but does not work with neither flings nor arrow key press.
I hooked to View.onScrollChanged() and it is called when scrolling happened, but I can't determine when scrolling animation ends.
In theory there should be a way to say that fling movement is over. Is there such API?

View 1 Replies View RelatedIs there a way to get a system notification when an app has been uninstalled?I would like to maintain a table of all clients' info currently using my app. However, that seems impossible if there is no way to detect this event. The first solution I can think of is to have an always running service in the background listening for android.intent.action.PACKAGE_REMOVED. But then would that service be killed once the uninstallation process has ended, or would it be stopped just before the process has kicked off? Also even if this is a solution it's has the potential to put off a lot of people when they realise that part of the app is running in the background.
