I am new to android just now i started to working on android,in my application i need to draw a 3 graph in one layout.I have attached the image exactly which out put i want..please help me to solve this problem
thanks in advance!
to draw graph what you can do is
1) put canvas on layout.
2) devide it on appropriate size.
3) draw on canvas directly.
may be this technique is tedious but its most efficient & easy to understand.

Not sure how to do this, or what the right terms are for describing this, but here goes:
I want to make a closing circle animation in my android app, much like the end of this video. I'm guessing what I need to do is somehow draw a black circle but instead of filling the inside of the circle fill the outside. How exactly would I do that, given the tools I have with Android's Canvas class?
Have you tried using clipPath to achieve this?
I was working on the same kind of thing and achieved it by using clipPath of canvas.

You might need to draw this you self. If seems doable. But if you dont know how drawing is done, these tutorial should help.
Just use a combination of drawRect and drawLine to get this drawn.
I am new to android and i could really use some help here. I have two images both are PNG one represents a gauges and the second is the needle. I am trying to animate the needle according to speed (rpm), what i need help with is the animation portion. Any ideas?
You have two choices. You can use Canvas 2D and render it that way, or you can use the Android Animation framework with ImageViews.
I'm trying to create a simple Pegs game. I have drawn the 15-hole board using canvas. I have been programming a while, but games are new to me and I'm stuck on what to do when it comes to handling the pegs. I want to only use the touch screen, but it seems like it is really difficult to touch the pegs and actually select them individually. I plan on just drawing everything programmatically. What is best way on handling this? Using buttons as place holders and changing the button image? Any help would be greatly appreciated.
To be very brief, you have to keep track of the things you draw on the canvas.
I wrote some tutorials for making and moving selectable shapes on the canvas. They should help a lot.
On android it might be a little different than using mousedown, but it should give you a very good starting place.
I don't know if this will help, but you might want to write your own onTouch()function. Check it out
I would like to design a layout for my android app which has imageviews/Textviews placed as shown in the figure below.
Right now, i tried to use Absolute layout, but i know that will create problems as the screen size changes.
Please help me with your ideas.
All comments are welcomed.
Thanks & Regards,

You should use 2D Graphics to draw shapes, 2D Graphics.
Hmm I think my approach will be to calculate some function that will model the curve (maybe two functions one for yellow and one for green 1/-x seems good) and then draw the circles with center coordinates like x = f(x). You can do this by simple implementing custom view and override onDraw method.
