I am trying to pick images from the gallery in my android application and I want to place them above each other,
but the problem is that I want to use only a single image view.
Does anyone know the code for that?
Thanks for your help.
Hi.
I am trying to implement a feature in the app that blurs some part of an image based on users (selection/touch) the selected area. I have implemented the code for whole image. But I am unable to find any example for the specified area of an image. So, please help me which type of example will use.
Just search before posting here :

Now i am going to develop this link to drag and drop the selected blur area. But i am not getting to drop this blur in other area. please help for this.
I am trying to create an application which has a map image in it.
I want to add some areas (or buttons) to it so that when you click them the bubbles with information will appear.
I am new in android programming so asking to explain a bit how to implement it?
Also i need an image to be re-sizable just like a real map.
So should i attach the buttons to specific places on image and how to do so that the buttons will be connected to it when i re-size an image?
Which image type is better to use for this purpose? I heard that SVG would be better but i couldn't even add svg image to an application.
I appreciate any helpful advice.
For your problem you can use this:

I need something similar, but the click on the image should change the content of that part as well.
When I find or implement the final solution I can post it here.
Sorry Guys for all the vague questions. this is what i want to do. I want my app to randomly play images from SdCard and I want no user input after app is started. I have read lot of sdcard post but this is not same question. if this is possible please let me know how i go about this. I do not want any user input once the app is started it just plays images from sdcard. Thank you for your help. by the way i am trying to implement this using android.
To show a slide show of images from your sdcard have a look at http://codinglookseasy.blogspot.in/2012/08/image-slide-show.html. Hope this helps you.
Get the image paths into the sdcard and pass it to the gallery.
You can follow this link for few more information http://raivoratsep.com/114/android-gallery-tutorial-working-example/
suppose you get the path name as
String pathName = "/sdcard/images/abc.jpg";
You can set the image to the image view as
Drawable d = Drawable.createFromPath(pathName);
hope this may help you
try creating another layout-land folder with the same xml file as in the layout folder.
This will be used as the layout when the mobile is in the landscape mode.
And to prevent crashing try to use
System.gc();
in the ondestroy()
And i didnt find any difficulty by adding new images.
They work fine for me.
I am browsing the web but no way to find how to get metadata from a picture.
Does anyone has an idea ?
I can't see anything in the Bitmap/BitmapFactory/BitmapFactory.Options documentation that would give me a hint.
I would like to retrieve standard information such as :
name
date it was taken
dimension
size
and maybe more.
Any idea ?
You can get at least the size of the image by setting BitmapFactory.Options.inJustDecodeBounds to true.
If the image is in the MediaStore, you might be able to get more information.
According to this thread
http://osdir.com/ml/AndroidDevelopers/2009-02/msg00821.html
you have to use ImageManager
