Android :: Animation Does Not Work Probably Screen Redraw Error
Apr 15, 2010
I have created a custom component in my program by extending a ViewGroup. This component listens to touch events and are supposed to start animations when the user has move their finger past some certain points.I'm able to start animations while the user is touching the screen. But I'm not able to start animations if the user doesn't move their finger. It's probably that the phone thinks it doesn't have to update the screen if the user isn't moving their finger.I added some logs and according to them the animation starts and ends but it doesn't draw on the screen. I have the same problems when starting an animation with a timer.I use AlphaAnimations and Translate Animations on ImageViews. I have tried to use invalidate() both on the component and the ImageView but it doesn't help.Anyone who has an idea how to solve this?

I'm fading out an imageview with alpha animation. I'd like the image to stay transparent after the animation. Tried with different combinations of fillAfter and fillEnabled, no luck. How can this be achieved?

I made this animation. Everything seems to be okay, but when I boot my phone with it, I just get the default Android boot animation like I normally do when I don't have a boot animation. I didn't compress it or anything.

I try to see a radar animation on a weather web page (m.yr.no/sted/Norge/Nordland/Andøy/Dverberg/radar.html) but get only the first picture. It is a gif animation. I downloaded it on my computer an tried to copy it to the mobile - with the same result. I just see the first picture of the animation. (it's about 2 MB)

I have an expandable list view with a static array for the group data and an SQLite database for the child data. It is implemented with the BaseExpandableListAdapter and works great, except, when I edit the database to delete or add children to the list I do not see the changes onscreen. It looks like I can use the registerDataSetObserver method to notify the adapter and expandable list of a data change. What I have to do in the callback to make Android redraw the list after data changes is what I need to know. Can I do it? Documentation on this part of the SDK is a bit sparse and expandable list view example code is not a good match. Can anyone offer advice on how to use a DataSetObserver? It feels like I have to switch over to a Cursor type adapter.

I've found that after changing the overlays on a MapView, the changes aren't seen until the user moves the Map, causing a redraw. Is there a way to force this redraw?

I'm implementing a fairly standard app with the Android sdk that involves drawing using the SurfaceView, SurfaceHolder, Callback setup.
In my main thread (UI thread) I have no drawing or handling of the SurfaceHolder (or the canvas you retrieve with it).
In a separate thread I have the following:
CODE:...............
This code is being executed, throws no exceptions, and has no negative side effects that I can find; however, the unlockCanvasAndPost() call never causes onDraw() to be called.
In other words, unlockCanvasAndPost() does not cause a redraw of the SurfaceView.
Any ideas what could cause this symptom? I have plenty of java experience, a fair amount of android experience, and a lot of debugging experience and cannot track this one down.

I want to get a set of Views to redraw after I change some drawing parameters. I'm calling invalidate() and forceLayout() on the parent of the Views but nothing happens. If I rotate the screen then the Views redraw correctly using the new parameters, as you would expect. What else do I need to do to get the Views to redraw?

I have a custom view, that overrides the onDraw() method. For better performance I want to redraw only a small part of Canvas in onDraw().

I have a custom view that fills my entire screen. (A piano keyboard) When a user touches the key, it causes invalidate() to be called and the whole keyboard gets redrawn to show the new state with a touched key.
Currently the view is very simple, but I plan to add a bit more nice graphics. Since the whole keyboard is dynamically rendered this would make redrawing the entire keyboard more expensive.
So I thought, let's look into partial redrawing. Now I call invalidate(Rect dirty) with the correct dirty region. I set my onDraw(Canvas canvas) method to only draw the keys in the dirty region if I do indeed want a partial redraw. This results in those keys being drawn, but the rest of the keyboard is totally black/not drawn at all.
Am I wrong in expecting that calling invalidate(Rect dirty) would "cache" the current canvas, and only "allows" drawing in the dirty region?
Is there any way I can achieve what I want? (A way to "cache" the canvas and only redraw the dirty area?"

I have a RadioGroup view inside a LinearLayout. The radio buttons are added from dataList. If I call the code below from inside onCreate, the correct button is checked. However the dataList can get updated from time to time and after that happens I call this code again, without destroying the Activity. After that, the view is redrawn but no button is checked. I suspect the RadioGroup checked-button bookkeeping is getting confused by the removeAllViews call. Any ideas what might be going wrong?

I am trying to get a slide down animation to work, and it seems to work except that it starts with a big black screen instead of the screen that was there. So I have layout1 and layout2. When I start the animation using ViewFlipper.showNext it puts a big black background over layout1 and then slides in layout2. If I use ViewFlipper.startFlipping() it slides in layout2 out as it is sliding in layout1 -- which is what I would expect.
My slide_down.xml looks like this:
<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android">
<translate android:fromYDelta="0" android:toYDelta="100%"
android:duration="4000" android:detachWallpaper="true"/> </set>
My java code looks like this:
ViewFlipper vf = (ViewFlipper) findViewById(R.id.DropDownList);
vf.setAnimation(AnimationUtils.loadAnimation(this, R.anim.slide_down));
vf.showNext(); or vf.startFlipping();

I have a strange issue - from time to time the animation that should fade out my control (ImageButton) does not kick in immediately. I am using the fadeout animation to hide it and then in myListener on its end (onAnimationEnd) I put new resource as the image on the button.
Somewhere in my app code:
Animation a = AnimationUtils.loadAnimation(this,R.anim.fadeout); a.setAnimationListener(new myListener(location)); buttons[location].setAnimation(a); a.startNow(); // regardless if its start() or startnNow() it will work in most of the cases but not 100% reliable I actually can see in debug Log when its late, happens after few more clicks
Then in myListener.onAnimationEnd(Animation a):buttons[location].setImageResource(R.drawable.standard_button);
Seems there is a rule that the every 4th or 5th animation does not start ...

I am new to Android development, just reading docs and trying the APIs. I am quit confused how ImageView managed to draw just a part of its content after an invalidate(Rect) invocation.
I've checked ImageView.java, found no other drawing method except onDraw(Canvas), but onDraw(Canvas) only cut the drawable only if it is beyound the view's visible boundary. I also read the implementation of View.invalidate(Rect), I think the key of this function is calling to mParent.invalidateChild(this, r);
However, I think the parent view doesn't know how to draw the child in the given Rect, it finally has to call some method of it child to paint out. Has anybody investigated this part of codes? Would you please give me some guide?

I have a ListView containing a few different type of items, all having their own background image and font color. In my first implementation I implemented each type of item as its own layout with the background image etc defined in XML (and implemented Adapter.getView() so that it only reuses convertView if it's of the correct type). This works fine but the performance is not that great while scrolling since I'm inflating quite a few Views due to convertView mismatches, so instead I tried using the same layout for all items (to benefit fully from convertView reuse) and changing the background image and font size in runtime. I even keep the three background Drawables I need as members to save time decoding them from a resource for each item, and call View.setBackgroundDrawable() from Adapter.getView(). The problem is, sometimes the 9-patch is not correctly wrapped around the content of the list item when using this approach. While scrolling it usually looks correct but when the scrolling stops, or sometimes when I just tap anywhere on the list, the background 9-patch of some large items starts flickering and is either cropped or resized to its original PNG size rather than stretched to wrap the content.
First of all, I suspect this is a bug? Any ideas why this happens? Could it be that the View is not always measured to reflect the changed content when the 9-patch is applied? I have tried adding an extra call to View.invalidate() but it doesn't solve the problem. Second, does this approach sound reasonable at all, or how should I go about to optimize this scenario?

We are using TextView's Ellipsize function to scrolling text in it and there many other controls in our window. We noticed CPU would go up to 50% if text started scrolling. After digging deeper, we found all controls in our layout kept drawing when texts scrolling. We wonder why? And how to avoid all controls redrawing?

Is it possible in Android to get a callback when a Frame Animation (AnimationDrawable) has completed playing its frame sequence? I know when a Tween Animation has completed, it calls onAnimationEnd(), but is there something similar for frame by frame animations?

CM7 unlock screen fade out animation?
I was using CM7 passion (nexus one) nightly #237 and I've learned that everytime I unlock my phone using CM7 lockscreen, it auto fades out into the homescreen.
But yesterday I was flashing to the latest update #253. I could not get back the little fade out animation after you unlock the CM7 lockscreen. Any trick to enable that?

Has anyone else noticed that after updating to Froyo, that text wrapping/redrawing is not working properly while web-browsing?For example, if you go to a text heavy website, like Reddit, and I zoom in (either by double-tap or pinch), the text will redraw, but it will be slightly larger than the screen's width. To read the text, I am required to scroll a bit to the right, then back to the left, and so on.I never had this problem prior to the Froyo update. Can anyone else confirm that they are having this problem? before I get bombed on, I should say that I am very happy with Froyo in other regards. I have not had any battery drain issues or any lag anywhere. I did not do a factory reset.
