Re: [android-beginners] Re: Optimizing drawing on a canvas
On Thu, Apr 22, 2010 at 1:08 AM, Indicator Veritatis mej1...@yahoo.com wrote:
Are you calling the Drawable method setBounds()? Android Graphics will
check to make sure the rendering is inside this rectangle before
actually putting pixels on the screen.
It's a png I've loaded from drawable, I suppose setBounds() is called
when loading the image?
Dumbed down a bit am I doing (obj.myBitmap is a large bitmap
containing several images and I just want to show one, that's the
reason for haveing a source rect):
Rect vp = new Rect (100, 100, 400, 300);
public void draw (Canvas c)
{
// normalize the position of the object
Rect transformedPos = new Rect (obj.pos.left - vp.left, obj.pos.top
- vp.top, obj.pos.right - vp.left, obj.pos.top - vp.top);
c.drawBitmap (obj.myBitmap, obj.imageMetricsRect, transformedPos, null);
}
This is called very frequently so I'd like to optimize it fairly well.
But at the same time if canvas does the same check would the trade off
of having the check all around to save a call doing the same thing not
be worth it. So to be precise this is what I would add:
Rect vp = new Rect (100, 100, 400, 300);
public void draw (Canvas c)
{
// normalize the position of the object
Rect tp = new Rect (obj.pos.left - vp.left, obj.pos.top - vp.top,
obj.pos.right - vp.left, obj.pos.top - vp.top);
if (tp.left vp.right tp.right vp.left tp.top vp.bottom
tp.bottom vp.top)
c.drawBitmap (obj.myBitmap, obj.imageMetricsRect, tp, null);
}
So I suppose my question is: Does Canvas just draw everythign being
thrown at it and then crops to the size of the screen or does it check
if there's a point drawing and then just draws the visible parts?
If it's option 1 I would assume that checking both if any portion of
the image is inside the screen and adjusting the src rect to be the
visible part would make sense?

Hi all,
I just wonder if Canvas.draw... checks if I want to draw outside its
bounds and skips thoose parts or if I should do the math myself. The
case I'm having is that I have an update and the user has scrolled
away from that part of the screen. Should I bother adding an if
statement around the drawBitmap or is the only overhead that draw is
being called and just doesn't do anything?
Thanks in advance

If you download the NDK and look at the examples, it really isn't that difficult to add a library. In fact, it is recomended to place any mathmatical processes into c/c++ code rather than java to speed up processing. Once you have the c library, you can drop the file into your android lib directory on any of your projects and it will be compiled into you APK.

you can use the function putExtra() while creating a new intent, and use getExtra() after the new intent has been created. that is assuming, you are using intents for forms. //make new intent code //call new intent code putExtra(key name, data) and where the new intent is picked up, in the called class, just use getExtra(key name) that should do it.

[android-beginners] Reading Notifications
Hi there. I'm new to Android development but have done amateur programming since high school. I would like to find out if there is a way to query the NotificationManager for all of the current notifications. I already understand how to create them and the difference between the different types of notifications. However, I would like to be able to have the phone perform actions based on the presence of notifications from certain programs. I have seen a few programs (like SmartVibrator) that can create custom vibrate patterns for phone calls and SMS messages, but I'm unclear on how it works. Questions: 1. Can I ask the NotificationManager for a list of current notifications? 2. Can I intercept or identify notifications without hacking NotificationManager to pieces? Thanks for the help!

No, sorry. Intercepting notifications, in particular, would be quite the security loophole. In general, on Android, one application cannot see or mess with another application's stuff.

[android-beginners] Re: Downgrading 2.1 app to 1.5
And above all, don't confuse your own 'R' with 'android.R'. They are different files. To get setContentView(R.layout.main) to work, Eclipse needs to find your 'R', not Android's. 'R' is supposed to be automatically generated by Eclipse whenever you add a line to the relevant XML file. But there are bugs in the build system. Usually you can work around them by doing 'Clean' on the project. If that doesn't work, escalate by closing and re-opening the project, turning build automatically off and then back on...

However, it was originally built for 2.1, and when I set the target as 1.5 I get some errors: Don't set the Target to 1.5, just set the minSDK requirement to 3. 1. 'invalid resource directory name' - the directory exists and is unchanged, the contents are listed in the Eclipse browser. Errors shown on re/drawable-hdpi, re/drawable-ldpi and re/drawable-mdpi Different resolutions was added in 1.6 so they're invalid in 1.5. 2. 'R cannot be resolved'. This appears to be the fact that R.java is no longer present. I've fixed this by importing android.R (not sure why it needed to be done again), but now The resource file is generated from your resources. Fix the above issue and this should build fine. setContentView(R.layout.main); cannot be resolved.

[android-beginners] Is it possible to 'listen' for sent SMS messages?
Hi, From what i can tell, you can create a broadcast receiver for listening for received SMS messages, but I want to listen for sent messages. Can this be done?

[android-beginners] Question on web service mobile client app for Android using ksoap2.
Hi I am creating web service clients in mobile devices (Android) through the use of ksoap2 libraries. http://developer.ebay.com/DevZone/finding/Concepts/MakingACall.html states: For the Finding API, no URL parameters or HTTP headers, including X- EBAY-SOA-SECURITY-APPNAME can be specified in the SOAP header. If they cannot be specified in SOAP header, how else can it done (preferably using ksoap2 library). I tried appending parameters to the URL, then calling AndroidHttpTransport androidHttpTransport = new AndroidHttpTransport(URL); (everything else prior to the call is done, sorry for not posting the code) but this yields soap fault. Any thoughts/ suggestions? Thanks. Anjana. -- You received this message because you are subscribed to the Google Groups Android Beginners group. NEW!
