Want to create a layout for Redeem Items. Kindly suggest or help how can I accomplish this easily?
Check this image for the idea
Dark Version of the item
You can't set a shape for a view. A view is always a rectangle. What you can do is make a view with a custom background with a non-rectangular shape and transparency in the area outside the shape, and use that as the background, which will make it appear as if it has a shape.

Im trying to make a button go from point A to point B, but i need a soft movement, not a jump. Like a tranlation. How can i do it?
make changes as per your need
Animation animation = new TranslateAnimation(0, 500,0, 0);
animation.setDuration(1000);
animation.setFillAfter(true);
yourButton.startAnimation(animation);
yourButton.setVisibility(0);
OR
You can create Translate animation using ObjectAnimator. check link for more information
ObjectAnimator transAnimation= ObjectAnimator.ofFloat(YourButton, propertyName, fromX, toX);
transAnimation.setDuration(3000);//set duration
transAnimation.start();//start animation
Example
ObjectAnimator anim = ObjectAnimator.ofFloat(yourButton, "translationX", 0,200); and then
anim.setDuration(3000);
anim.start();

I need an algorithm or preferably a library, that will assist with arranging a diagram. I can already draw my diagrams, I just need arranging.
A diagram consists of one or more different sized rectangles, they may be connected. Some rectangles must have fixed positions, and the goal is to minimize total connection length. For example, this diagram where red squares have a fixed existing position, and where green squares should be positioned to minimize total connection length.
An optimal scenario is for me to input a graph, where nodes are rectangles and edges are connections. Nodes would have a certain size and possibly a fixed position. The output will be a set of XY coordinates.
I would like to know either an algorithm or library for such a task, thank you.
I have already looked briefly at JUNG and Graphviz, but I fail to see how they might solve my problem. Also, the final program will be an Eclipse plugin, so I would like to be able to easily bundle any external dependencies.

I want to rotate a BufferedImage from a math phrase so that become like this :

convert to :

we have not images and them include by user.
Minimize axis aligned bounding box area.
Simplest algorithm could do coarse estimation every 10 degrees. Pick best angle and do refinement with smaller angular step.
Probably you should pick wider rather than taller result.

I search for Java free open source shapes library,
That contains shapes like: Triangle, circle, Square, Polygon and etc'.
Of course it's should be graphics and not textual (terminal \ cmd).
Do you know about good one? Thank you.
Check out two particular ones (if you're still looking) the MyroJAVA program- this one is really designed for robots, but surprisingly has some pretty good Graphics library. http://wiki.roboteducation.org/Myro_in_Java
Also this library from Williams College: http://eventfuljava.cs.williams.edu/library.html
That contains shapes like: Triangle, circle, Square, Polygon and etc'.
With exception to triangle, the Java Graphics API already contains all theses, and to be honest, triangle wouldn't be that hard to implement (it's a closed polygon with 3 points after all)
I'd start by reading through 2D Graphics, in particular Working with Geometry

Is there any code(specifically Java or C++) or software in which we import any image and it gives the outline of that image in points, which we can use again to draw image outline by joining those points in JOGL or OPenGL ..
There's an outline tracer in Inkscape (which is open source c++).
http://inkscape.org/doc/tracing/tutorial-tracing.html
This will convert to vector format - so you could get some points out this way.
EDIT: this actually uses http://potrace.sourceforge.net/ for the tracing..
Here is an example code in MATLAB:
%# read image
I = imread('coins.png');
%# Convert to a binary image
BW = im2bw(I, graythresh(I));
%# get object boundaries
BW = imfill(BW,'holes');
B = bwboundaries(BW,'noholes');
%# plot boundaries overlayed on top of image
imshow(I), hold on
for i=1:numel(B)
plot(B{i}(:,2), B{i}(:,1), 'Color','g', 'LineWidth',2)
end
hold off
