Android :: ProgressBar Not Animating

Aug 26, 2010

I'm drawing a ProgressBar in a custom View (SurfaceView) to it's Canvas, and it's drawn as expected. Except that it's not animating, no matter what I do. My custom view is animated properly, but I cant change the progress of the ProgressBar.

I've created the ProgressBar like this:

CODE:..................

And I draw it something like this (slightly simplified):

CODE:........

And I've tried updating it's progress manually as well:

CODE:.................

Any ideas on what I need to do in order for my ProgressBar to animate or change it's progress.

Android :: Animating A Layout?

Apr 8, 2009

How do I animate a Layout?

I have a RelativeLayout which sits in a certain position within my Activity; I want to glide it in and out from the bottom of the screen when a certain button is pressed.

I have found examples of animating the children of lists etc but this is not what I want. I simply want to animate the whole layout and the views within it together.

Android :: Animating App Widgets?

Jun 22, 2010

I have tried a weather widget and its working fine. The Weather widget is an app widget and I update the widget once in 6 hrs similar to the application on android site using AlarmManager. Now I want to animate the widget (ImageView) every 100 ms similar to HTC homescreen.

I dont think AppWidgets will scale well for this case. How can I implement this widget?

I have seen "Custom Homescreens" in previous Android SDK's. Should I have modify the Homescreen widget for doing this or is there any other way.

Android :: Drawing And Animating?

Nov 5, 2010

This is more of a question about animating than a specific problem coding. i need to fill in the broad strokes left by the research i've been doing.

What i'm trying to do:

The activity should load with only the a togglebutton visible. when the button is touched, a png will be animated to a certain position relative to the togglebutton. also, another button will slide in from off screen and slide off if/when the togglebutton is pressed again.

What i can't figure out:

I can draw an image, but only via xml. creating an imageview and setting the background programmatically does nothing.

When i draw from xml, i can't move the image when the togglebutton is pressed like i want to. when i call getPositionOnScreen() i get a null pointer, even though the complier can see i'm referring to the imageview described in both xml and in code.

I'm calling getPositionOnScreen because via xml, i have the image positioned behind the togglebutton so that it's not visible until the button has been pressed and the image starts moving. the idea is that with different screen sizes i won't know exactly where the view is until runtime. getPostionOnScreen allows me to get the coordinates of the imageview so i know where it has been positioned. when i have a start position, can tell it to "move up" on the screen from behind the togglebutton by simply adding to x or y until it's where i want.

This is the code to draw the image (inserted in the onCreate method).

CODE:.......

This is the code i'm using to animate. when the button is clicked, it calls this method on the view from the listener.

CODE:...............

I'm well aware that this is horribly wrong and won't work. what i need to understand is why.

Android :: Animating Drawables From Within SurfaceView

May 19, 2009

I am using a SurfaceView, and wish to animate Drawables. All the animation tutorials I have seen concern using an ImageView, which as I understand is not a sensible approach from within a SurfaceView. Does anyone have any suggestions for doing frame-by-frame animation within a SurfaceView? Can it be done with openGL?

Android :: Animating The Background Of A LinearLayout

Apr 27, 2010

Is there a way of being notified when a TransitionDrawable has finished its transition? I'm looking for a way to animate the background of a LinearLayout, switching it back and forth between two images thus creating a pulsating effect. TransitionDrawable works nicely, but....once. I tried stacking several 'item' in the XML defining the transition, but no luck. It justs fades from item 1 to item 2 and sits there. I'm wondering if I shouldn't implement a custom Animation.

Android :: Animating Different Views During The Same Animation

Nov 10, 2010

Does anyone knows if it's possible to animate different views during the same animation: I have a linear layout containing 6 dices (each dice extends a textview) and I need to animate each dice to simulate a roll (each dice will rotate on itself). I know how to do this rotation on each dice by using 6 animations, but I want to group these animations in one, so that I would be able to add an animation listener to execute further instructions at the end of this animation. I tried with an animationset but didn't manage to do it.

Android :: Animating View Position?

Feb 3, 2010

I'm trying to do something which seems simple. I want to have a map view, with a menu that slides up from the bottom of the screen where settings (for overlay) can be adjusted. However when I use a TranslateAnimation to affect the y position of the LinearLayout (which holds the menu), the buttons in the LinearLayout move, but there "hit area" stays in the same position as they were before the animation.

CODE:.........

I've also looked into tweening the view's marginTop value, but haven't even been able to determine how that would be done.

Android :: ProgressDialog Created From OnCreateDialog Stops Animating On Second Run

Sep 29, 2010

I create a ProgressDialog in onCreateDialog() like so:

code:.........

Android, in its wisdom (or serious lack of it) decides to cache every dialog created through onCreateDialog(). Because of that, any subsequent call to showDialog(DIALOG_PROGRESS_ID) results in the same ProgressDialog instance being used but the animation has stopped working.

I've tried to re-set indeterminate in onPrepareDialog(), but that doesn't do anything. There is likewise no obvious method to call on the dialog instance that will reset the animation.

code:................

But maybe there is a way to get the ProgressBar itself and start it animating? so I tried the following after I asked this question:

code:........

But it didn't work either!

So, does anyone know if there is a way to restart animation on a ProgressDialog? If not, is there a way that I can force every showDialog() call to call onCreateDialog()? (this second question was answered by @TuomasR, but after pondering it I don't think this is a very good solution to my problem)

Android :: Animating A Drawable On A Canvas Inside A Surfaceview

Sep 2, 2010

Is there a way to animate drawables on a canvas using the android built-in animation classes?

Ive been modeling my test application, a game, after the example apps lunarlander and jetboy. They contain a lot of reusable code, but they manually update the drawable objects in real time. It seems like using the android animation built ins would be so much easier since they provide the type of animation I need�a simple linear movement.

Is there a way to do this, or am I better off updating my canvas in real time much like the example apps.

If there is a way, could anyone get me started with some sample code? I am currently inheriting SurfaceView in my class.

Android :: Scaling - Animating Camera Preview Surface

Sep 20, 2010

I am using android.hardware.Camera to get a preview and display it on a custom SurfaceView that implements SurfaceHolder.Callback.

I am trying to zoom in to the camera preview surface by a specified scale (not using the camera's digital zoom) but I can't seem to find a correct way to do it. I also need to be able to zoom out and scale down the preview.

I was hoping to be able to do this using a ScaleAnimation but it doesn't seem to work on SurfaceView, nor the FrameLayout containing the SurfaceView.

I also tried setting the size of the SurfaceView using setLayoutParams but that doesn't seem to work too well on various hardware and it would be tough to animate smoothly.

How to achieve this effect? Right now I am starting to think I might have to implement this using GLSurfaceView but I'm very unsure.

Android :: 1.5 Quits For Apparently No Reason Whilst Animating - WIN DEATH

Nov 22, 2010

I have an app that is working fine in 1.6 and up but crashing for apparently no reason in 1.5. The app suddenly quits with the following message...

CODE:............

This error happens when the app is 'idling' (ie not doing anything other than redrawing the screen). There is no state change and no user input. The error occurs after the same amount of elapsed time whatever I set the frame rate of the app to and occurs both on the emulator and device. Changing what I display on screen can stop the error but there appears to be no logic to this (in one instance not drawing a large image stops the error but elsewhere just drawing some text causes the app to crash in the same manner).

I am using SurfaceView for animations following the basic procedure in the Lunar Lander sample app.

Android :: Communicating Thread With ProgressBar

Nov 14, 2009

Here is my code:

CODE:......

The problem is as follows: progressBar is showing correctly. mHandler obtains the message but only once(for the first time). But I need to make it in loop(as Looper.loop should have worked in this case), so it calls mHandler handleMessage in every loop(but its not happening in this case). The outcome progressBar kept on rotating though the condition in the handleMessage (if(location!=null) )is getting satisfied in the mean time of the active progressbar. How can I make mHandle,sendEmptyMessage to call in each loop so I can check for this (if(location!=null)) condition.

Then I close my application and start it again, and, progressbar is displayed without padded background, on next start will be displayed correctly and son on ... Could you please advice possible reasons for this?
