View 2 Replies View RelatedAndroid :: SurfaceView Vs Custom View / SurfaceView Is Slower
Aug 20, 2010One using a Surfaceview, and the other using a custom view. According to the android SDK development guide, using a surface view is better because you can spawn a separate thread to handle graphics. Th SDK development guide claims that using a custom view with invalidate calls is only good for slower animations, less intense graphics.However, in my simple app, I can clearly see that using a custom view with calls to invalidate seems to render faster.What do you guys know/think about this?My touchEvent code is exactly the same, and my drawing code is exactly the same. The only difference is that one is all in the UI thread, and the other is using a tread to handle the drawing.

Nov 12, 2010The phone is one day old. Whenever I recieve a text.I get the notification in the top left-hand corner and the display will stay up until I press the sleep again. It will fade out in any other circumstance but whenever I get a text, the screen stays lit until I do something.The phone is brand new. I have only installed a live wallpaper. And the delay IS set to 15 seconds. The delay works on everything but that screen. It wastes so much battery in my pocket when I get a text and don't check it as the screen stays lit.

View 1 Replies View RelatedAndroid :: Blinking Image Using Alpha Fade Animation
Oct 11, 2010I've been struggling for a few days on this, finally just decided to ask. It's so simple I've got to be missing something very basic.I have an XML layout page with an image defined. I have two anim XML pages, one to change alpha from 0 to 1, and the other from 1 to 0 in order to create a "blinking" effect. So the alphaAnimation is defined in XML, I just need to call it. The image pops up, but there's no looping blinking effect.
View 2 Replies View RelatedCustom Drawable Making Edge Of Image Fade Out
Jan 22, 2014I have a custom drawable, where I draw a base bitmap image, then part of an image over the top of that that is clipped to a certain rectangle. For the overlayed image, I am trying to blur the edges, and I thought I could accomplish that using a BlurMaskFilter, however, I'm not seeing any blurring occurring.
Here is the content of the draw method from my Drawable class.The result is almost correct, except the overlay image is not being blurred.
m_paint = new Paint();
m_blurPaint = new Paint();
m_blurPaint.SetMaskFilter(new BlurMaskFilter(blurRadius, BlurMaskFilter.Blur.Outer));
[code]...
This code is written in C# using Xamarin, so I realize that some things are slightly different, but the overall methods will be the same.
Android :: Color Banding - Png Resource That Has Gradient Fade-out Alpha
Oct 29, 2010Seems my original post ("ugly pngs...") somehow disappeared :( nvm.
I have a problem with a png resource that has gradient fade-out alpha.
The png looks great in the emulator, but displays an artefact known as "color banding" (http://en.wikipedia.org/wiki/Colour_banding)
Has anyone surpassed this issue ?
My designer wants to trop a shadow behind his icons, and that's where the bands appear.
What are my options ?

Jul 18, 2010Is there any way to change when these 3 things happen separately? Can I make it so my screen fades earlier but still takes just as long to go completely black? Is there a way to extend the time between total blackout and locking? Is there a way to turn off auto screen lock all together but keep the auto fade out and auto black out? I am always able to remember to manually lock the screen and the auto lock is annoying but I still like the power saving of the screen fade and black out.

View 2 Replies View RelatedAndroid :: SurfaceView Fast Enough For Emulation
Sep 11, 2010For years now I've maintained a Tandy Color Computer Emulator applet on my home page. With the purchase of an Incredible I decided to do a port. Getting it going in Android didn't take long but I'm really surprised how slow it runs. You can literally see the pixels painting. I know there are other successful Android emulators so I must be doing something wrong.
My approach was to use a SurfaceView for rendering. There's a separate thread that runs a virtual 6809 CPU. Whenever that thread updates the emulated video memory, it calls SurfaceHolder.lockCanvas() with a Rect describing the part of the screen requiring a repaint. Then it calls the gfx routines with the resulting Canvas...this is where I did a repaint() in AWT/Swing. The gfx routines are smart enough to just render what's in the clipRect. Perhaps I'm still stuck in AWT but I can't think of any way to make this thing run at an acceptable speed. I tried to coalesce the gfx calls but that didn't work either. Any thoughts?
Android :: SurfaceView Transparent Through Its Parent
Feb 11, 2009I have a SurfaceView that is covering a portion of its parent, a RelativeLayout. I have a background image covering the full RelativeLayout area, and this is my Activity's main layout.
I would like to have the SurfaceView be transparent so that I can see through to the background image on its parent RelativeLayout. I have tried the approach shown in the API Demos example TranslucentGLSurfaceViewActivity, but this succeeds in making the transparency go all the way through my Activity to my desktop!
I'm using the "style/Theme.Translucent" theme on my activity, and setting this on my SurfaceView: mySurfaceView.getHolder().setFormat(PixelFormat.RGBA_8888);
The transparency to the desktop it kinda cool, but not what I'm trying to do! Is it possible to make a SurfaceView transparent only through to its parent?
Android :: Difficulty Resuming SurfaceView
Apr 24, 2009I am stuck.My main activity creates and starts a SurfaceView.My app needs to access a listview via the options menu to change properties of the items shown in the view.Two strange things occur:
1.) When I scroll the listview quickly, the list sometimes gets farklempt.Words overlap each other.
2.) When I select the item and the app returns to the main activity, the thread is no longer alive.
If someone out there can offer help I will post the code.This will take a little effort.My code is loosely based upon LunarLander and the GLSurfaceView examples.If there is a good example (more recent example) someone can point me to, that would be boss.
