I have 2 images and I want to overlay them and get the same effect as in photoshop's "overlay". Overlay porterduff exist in PorterDuff'd documentation but I guess not for android 2.2.
any idea on how to implement this?
thanks
They have added it to the PorterDuff.Mode enum, but im not sure from what api version, im pretty sure it's >2.2.api doc
You can just use LIGHTEN and darken your dst image to achieve a similar effect :)

I am new in android development. I want to make blur background layout. I read some blog but I didn't get that I want.
I want to make layout like this: http://postimg.org/image/azjkgbl3l/
Suggest me some blogs or how to do this.
Thank you.
There are some ways to do this,For API < 14, you could use the flag WindowManager.LayoutParams.FLAG_BLUR_BEHIND, but it's been deprecated and built-in blurring is no longer supported on higher APIs.So you can create a blurred bitmap and set it as background for the page. Refer the following links for more details.

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.
I have an image that is circular and I want to make the other junk in the image to be transparent. I've spent the last hour looking around and I can't seem to figure out how this is done for android. Any help is greatly appreciated!
I haven't worked with Android but on iOS pngs weren't loading for me when I made them in photoshop but when I made them in flash all of a sudden they would work! Try that first :)
Anyways, you want to google something along the line of "pixel arrays android code" you can create an array of each pixel, find an individual color, then make it transparent...
But I really think this is just a GIMP issue and you don't need to go through all of that hassle.
what i can understand from your uncleared words is that you want to display transparent image of a normal image you have . so i would suggest don't do it through programming . create a transparent image through any image editor tool and use it .
if image is dynamic that you cant go in this way so use Matrix and setAlpha . search over net for both the terms
I am testing a mobile site at the moment on android and have noticed that all my transparent images that have a shadow at the bottom are all rendering extremely poorly. I have tried adding noise>0.5>uniform>monochromatic to the image to solve this but this hasnt helped at all i also tried adding noise>2.0>gausiann>monochromatic but again got no change.
its clear that the image is being rendered as png8 even though im saving out the image as png24. i am also using the most up to date version of the android browser 2.3.3
Can anyone shine any light on this problem?
I know its old but the solution is here.
To summarize: Use following code in onCreate(), between super.onCreate() and setContentView() in your activity:
getWindow().setFormat(PixelFormat.RGBA_8888);
do you know how to make a certain part of a picture (jpg) semitransparent, like in the attached image?
Just use a PNG image instead. Problem solved :)
JPEG doesn't support transparency. Can you use a 32-bit PNG instead?
If you have an existing image that you want to apply some transparency pattern to, you will need to create a Bitmap object in code, draw your image, then set some flags to allow you to draw the transparency levels over it, a bit like a Photoshop layer mask. I did a search for Android alpha masking, and found this blog post.
Err - I may be utterly confused here, but why not just use setAlpha(int alpha) on the inflated ImageView?
That seems to work fine on a .jpg for me.
Or is it only part of the image that should be transparent? Hard to see the 'sample image'.
