Android :: Way To Have Image Overlaid Over Another Image
Mar 3, 2010
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?

Making the touched areas of bitmap image transparent(seems like erasing) while I am moving my finger on that image.
I am having a PNG file with Alpha channel in it. I want to turn the touched pixels to transparent so that, the user can feel that he is actually erasing it.
For this I am using frame layout to load 2 layers. Down layer is for content and upper layer is an Imageview for erasing. I need erase the upper layer when user touch and move his finger on it.
I am not getting how to make it transparent. can anyone please help me in this. If possible please direct me to any sample code, as I am very new to this image processing.

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 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.

I have an ImageView which I want to always be the same size. If the image is smaller than the view, I'd like it to be centred in the view. If the Image is larger than the view then I'd like it scaled down - with aspect ratio preserved.I've had several attempts at this myself

I've got a things to do with android, so, I have 2 images,
1. image from camera
2. another image from somewhere
So what I want to achieve is how to combine those image into 1 image, but it's overlapping (just like watermarking the image). The 2nd image should be scaled first into the size of the 1st image(camera) - so they have same dimension, then if the 2nd image pixel is black, don't combine it (so the black means transparent color - on 2nd image). Do you know what is the best way achieve this, can I do this with xor or bitwise?

I'm new here, so I thought I'd thank you all in advance for any help you may give me.
I am currently writing an application that stores its data in an arbitrary XML file under /res/xml. This XML file contains an element called <content>, which in turn contains two more elements; <text> Ppand <image>. This file will be used to create a layout with some text interlaced with images. What I'd like to do is get an image under /res/drawable with the information under the <image> element in my XML. However, I don't know how to do this. Does anyone have any ideas?
