Android :: How To Pause And Stop A Changing ImageView
Mar 18, 2010
I have an ImageView in which the picture switches every 5s, i am trying to add a pause and resume button that can stop and restart the action. i am using a Handler, Runnable, and postDelay() for image switch, and i put the code on onResume. i am thinking about using wait and notify for the pause and resume, but that would mean creating an extra thread. so far for the thread, i have this:
CODE:...............
And in the main activity's onCreate():
CODE:.......
The pause button seems to work, but then after that i can't press any other button, such as the resume button.

What I have here is a simple button that plays a looped sound while it's pressed. It works great. However, sounds.autoPause(); wasn't introduced until API 8 and I really need something that is cupcake compatible (API 3) So i was going through the dev reference site filtered by API 3 stuff and i saw pause so i figured i'd try sounds.pause(sound); but it doesn't stop the sound when i release it. (Maybe i'm just using it wrong?) Does anyone know of a cupcake friendly way to stop this sound? thanks!
sounds = new SoundPool(5, AudioManager.STREAM_MUSIC, 0); sound = sounds.load(this.getApplicationContext(), R.raw.red_long_one, 1); Then here's my touch event................

Wondering if I'm going about this the right way or not. I have 3 buttons on my screen (Restart, Previous, Next). When the view loads it shows the first image which is fine. When I click the "Next" button I want it to load a second image and so on for up to 9 images. If I click the "Previous" button it should go back one image. Clicking "Restart" should go to the first image. I have the Restart one working. I'm having trouble with the Next button because it only shows the second image (I think because my "a" variable is initialized at 0).

Currently android devices play/pause on audio cable plugin. But I need it to do the exact same thing with the charge cable. Mainly because I use a dock for music playback on one of my stereo's and would like to just drop it into the dock and it will start playing, or pull it and it will pause

I would like to be able to alter the size of some of my ImageViews based on what Drawable they are showing. I've not yet decided on whether I'll get them to read the new dimensions from the Drawable or if I will just have an array/enum storing the heights of these, but what I need help with is the actual changing of the ImageView size.Which of the many many function for altering sizes of things should I be using to change the size of an ImageView while still retaining it's relative positioning in the RelativeLayout it is a part of? I can't work out if I should be changing the bounds of the Drawable or if I should be redefining the LayoutParams of the ImageView or some other method altogether. The drawables are always going to be the same width, but their height will change depending on what is in each tile of a map (which this is rendering).

I have an ImageView on which I have applied rotate animation. Since I want the rotation to go on continuously, I gave the repeatCount as infinite in my rotate.xml
android:repeatCount="infinite"
In onCreate(), I load the animation and start it.
Animation myAnim = AnimationUtils.loadAnimation(this, R.anim.rotate);
objectImg.startAnimation(myAnim);
When a button is pressed, the rotation must stop. Hence in my onClick(), I called clearAnimation().
objectImg.startAnimation(myAnim);
My simple doubt is whether it's the right thing to do, to stop the animation?
I assume clearAnimation() is to loadAnimation(), but there is no stopAnimation() corresponds to startAnimation().

I am having problems with the calender changing the days I have appointments set for. I set a b-day appointment for the 29th and was looking yesterday and it said it was set for the first. I deleted it and started over with the 29th, check this morning and it says the 1st again.

Even though I change my FB to update every 2 hrs and Flickr to once day, when I go back to check, FB always resets back to 'once a day' and Flickr resorts back to every hour.
Anyone else had this?

I have contact pictures for my contacts that I have chosen and assigned to my contacts manually and are stored as the Google contact picture, I have an issue with the facebook app when it syncs a facebook profile picture update the application forces the contacts default picture to be the facebook picture.
I don't want it to do this, it can change the facebook linked contact picture but why does it have to change the contacts default picture?? Is there some way this can be blocked or stopped from within Android contacts??
This has been prevalent since before I can remember with the facebook app and sync. Surely submitting a bug to facebook is not the solution as we SHOULD be able to control and/or lock portions of our contacts details..

Is it possible to use bundle and save the data in OnPause() lifecycle method? The scenario is i have 2 edit text and have entered some data i want to retain the data when the activity is killed and started again. his can be achieved using onSaveInstanceState() but as documentation says, this method is not a lifecycle method and hence the callback is not guaranteed. So i wanted to know if there is a way to save it using Bundle in onPause().

I have an application that plays music. I want the application to get notified when the user plays a YouTube video so that I can pause the music in my own app. Is there a listener I can setup or a Broadcast receiver that I can setup to get notified of when the video is played.

I keep hearing that last.fm is better than Pandora, so I'm trying it out. But no pause button? Is this only for people who live in caves?

I see no means by which my activity can pop itself off the activity stack to return the user to the one he was using before it was invoked. Is there one? My purpose is that my app has some data structures built from data provider queries that take 5-15 seconds to assemble and I don't want a lot of latency if it is used in a few one-shot purposes in rapid succession. I'm more than willing to let the system ask my app to die, but I'd like to keep warmed and ready otherwise.

How do I do a simple sleep() in Android? e.g. in Perl:
sleep 5;
to sleep for 5 seconds. I have a program that continues scanning wifi until it finds a certain router then plays a tune once found. All works fine, but it scans in 1.6 EXTREMELY fast, where as on 2.0 it scans about once per second. I also made a stop button that does:
mainWifi.setWifiEnabled(false);
But this causes a force close. ? actually every application I have made so far except hello world just gives me a force close. I have checked my permissions in the manifest etc.? I have a soundboard app that cannot play more than 7 sounds before it force closes? why?
Is it my phones hardware?

I am getting reports that the in the HTC Magic the character that represents the pause in a dial string is different than in the Google build of cupcake. In the SDK 1.5 pre-release, the pause is given by a ','. Apparently, in the HTC magic, the pause is given by a 'p'. Unfortunately, I don't currently have the means to test this. Does anyone know if the PhoneNumberUtils.PAUSE member in the HTC magic build reflects this change? Have any other functions in PhoneNumberUtils changed in order to support this?

I need a Music player that allows you to pause an MP3 in the background and then go back to it. I have a long MP3 file (3hrs) that I need to pause during the day and switch to a different app and then back to the music player. Everytime I hit the Home button it stops the player.
Are there players that allow you to pause and go to another app?

I am learning about OpenGL and managed to write a prototype game using VBO buffers. If I start the application from Eclipse or adb, everything works fine until I press the back or <Home> button. If I restart the application either by a long press on <HOME> and selecting my program or by restarting it from the applications, I sometimes get a black screen and the LogCat shows this error:
CODE:...............
I am aware that it is probably a wrong setting in my program's flow, but I am not fluently enough with OpenGL.

I am having an issue with a looping audio file using MediaPlayer. I am developing a realtime game and have a 100K MP3 file I want to loop as background music. The size of the file means I can't pre-load into memory (using SoundPool) so I am using the MediaPlayer to stream the data.
All works fine, however if I set the stream to loop (MediaPlayer#setLooping(true)) when the stream gets to the end and MediaPlayer loops, I get a distinct pause in gameplay. Everything seems to hang for a good chunk of time (~100ms) presumably while MediaPlayer re-seeks to the start of the audio file, and this is killing my framerate and making the game unplayable at these points.
There doesn't seem to be a way to configure any memory buffers etc on the MediaPlayer, so I'm wondering if I am using the wrong approach?
Any other ways to run continuous background music?

I get the following error
CODE:...
When trying to execute this code in a service:
CODE:..........
When the service is first called and no MediaPlayer-object exists, the stream is started correctly. But when the onStart()-method is called again (with the player streaming) I get the above error code. I can't find any information about this error code, so I turn to you for help. Replacing mp.pause() with mp.stop() makes it work. Could it be that the stream does not support pausing? It's an online radio stream (RTSP) in the SDP format.

I have created an application that read messages with voice. I would like to pause any running media player when a message arrives in order to make the voice more clear. Is there any intent that could achieve this aim? I have noticed that google navigator, for example, is able to pause media player (and other music app like pandora).

I have an app that crops faces - something the app can do in a nanosecond, but I want the user to think it takes a bit longer. So in a case on a button click.
Here is what I have:
CODE:........
The dialog shows fine, and the faces crop fine too. The problem is - when the user runs the app, the 2 happen simultaneously on the screen.
Is there a way to make it so the dialog appears, 3 seconds elapse on screen and then the cropFaces is run? That way it will look like it cropped the faces in a few seconds, and then the new page appears.
