I'd like to include a simple draw feature on my app. A friend told me I can't use canvas because I need to control the frame buffer and not redraw the entire screen every for every frame.He suggested I find a openGL 2d engine.I've searched around and I've only found Rokon which doesn't have any documentation and the examples aren't quite what I need.Any suggestions?

I'm new to Android and Java programming and I've manage to create a simple paint program, but how do I add a zoom feature? Right now I'm just extending the View class and using the "on Draw()" method. Do I have to use a Drawable to be able to add zooming functionality? I'm not really understanding the differences between the two. If I am way off base then please point me to a good tutorial on paint/zooming.
View 1 Replies View RelatedMy app uses a custom View that does a lot of text drawing.To ensure my text is always readable I've been using the result of calling getTextSize() on a newly-created Paint() instance as the minimum size. Docs say calling 'new Paint()' sets attributes like text size to default values.One of my European users just got a Motorola Milestone phone and reports that some text is unreadably small.I believe I've duplicated this using the WVGA854 skin in a 2.1 emulator.Run in that emulator my app's smallest TextViews look fine, but the text I'm drawing myself using Paint instances where I haven't changed the text size from the default is too small. I confirmed this by commenting out all setTextSize() calls in my View subclass: the text becomes too small to read comfortably.

View 4 Replies View RelatedTo explain i have a bitmap which is constructed as follows
Paint a rectangle color yellow I want now to paint a smaller circle over the top of the rectangle, but i want to use transparency. so that the circle results as a hole in the rectangle. {like swiss cheese with holes }
So if i painted the bitmap over a background the background would still be visible in the Circle/hole.
setting the drawcolor drawColor(Color.TRANSPARENT) just paints a transparent object. i.e. it doesn't erase the circle area of the rectangle.
How to do...?
One option is to set the circle color to say black and then look for an option to replace black with transparent within the bitmap.... but i can't find a solution for this either.
I'm trying to develop an RPG for Android, so I need to paint a scenario where I'll move my character.
My idea is to do it 2D. I've developed 3D games and Java games for desktop, but in Android i don't get how to star the scenario.
Could it be developed with a matrix of information, so I could know where my character steps?
I'm designing a custom view which is an X/Y Plot. It's a moving graph that scrolls to the left with time and new Y values are continuously coming in at 10 per second.
I've been able to make it work with an array of integers where the array index is the X value and the integer value is the Y value, but this seems horribly inefficient (Because every time it comes time to re-paint, I have to loop 800+ times to paint the graph). Then we do it all again 10 times a second. yuck.
Can anybody think of a paintable object that I can draw points to and perform some kind of scroll transformation and then just draw the new points each time, rather than the whole canvas?
Any other ideas out there?
The issue I am experiencing is that the SurfaceView I am using flickers. Once in a while, the objects I draw flicker and they change their size or colour.
It looks like that sometimes the application skips my calls to 'Paint.setColor()' and the one to 'Paint.setStrokeWidth()'.
I have made methods which change the used paint and then, in order to try to fix this issue, to set it back to the default paint values. Still the issue persists. I have also read that the problem might be due to the double buffering. Is it the case? I am using this code for the DrawingThread:
I also tried to use a dirty Rectangle to try to see if the issue can be fixed, but still nothing. [I might not have understood what it actually does.
Code:
class DrawingThread extends Thread {
private SurfaceHolder _surfaceHolder;
private CustomView _cv;
private boolean _run = false;
[Code] .....
I have read somewhere I should draw on a single bitmap and then draw the bitmap on the canvas. I have tried several times but I cannot manage to do so.
I'm developing a coloring book app, how do I ensure that the black outlines of my drawing are not colored by the paint brush? I thought of decreasing the alpha value of the paint brush to show the black outlines when painting over them but upon painting the same area again, the black outlines will be painted over.
View 2 Replies View RelatedI'm using the FontFitTextView that was posted in this other thread, but it isn't working exactly right for me. The measureText() call is returning a number that is obviously too small to display the string. When it runs through to find a font size that will allow the text to fit, the font size it settles on is still too big. I feel like there is some other kind of padding or margin or some other invisible that is contributing the math that makes up the width which is causing the discrepancy.For example I want to set the text of my FontFitTextView to be "10,000.25".The width of my FontFitTextView is 96 pixels, with 8px padding on both sides, so my available width is 80 pixels. The call to measureText() says that the text "10,000.25" is 64 pixels wide. This means that the current font size should be small enough to display the entire string. However, when the string is actually drawn on the TextView the last 2 characters are chopped off and all I see is "10,000." instead of "10,000.25"

View 9 Replies View RelatedI've had the phone only since Tuesday, and I just noticed a dent in the paint, if that's the correct description, near the bottom right corner (an inch below the Search button, slightly to the right). It looks as if someone pushed their finger nail into the paint really hard. It's the same height as the letter G in "SAMSUNG" printed under the screen.
The phone was dropped by a child on the car mat once before, but I don't think that's what caused it.Any ideas on how to fix it, or if I can get it replaced? (I got it from letstalk.com for free with contract).
There seams to be a widespread problem of the gold coated camera button flaking and or wearing over time.

View 32 Replies View RelatedIt seems as though my kickstand almost needs some lubricant. It sticks somewhat over halfway open, and needs a push to fully open, as well as close. My question: what oil/lubricant would be safe enough to use without eating away the paint and finish on the phone? (I.E. WE-40 is definitely out). It's just annoying because I use it alot to prop up the phone and keep it off its back, and camera lens at that. It's annoying hearing it squeaking every time it opens and closes.

Is this a tab view? I don't need a tab view because I don't need the tabs to stay on screen after one is clicked.
