I want an animated gif, since this isn't possible in Android I am using individual frames in a transition.
except it seems like the transition class only will show two frames ever! I saw other animation methods but they didn't seem to apply to what I was doing, or seemed old and convulated like for an older infant android build
<transition xmlns:android="http://schemas.android.com/apk/res/android">
<item android:drawable="#drawable/activateanima"></item>
<item android:drawable="#drawable/activateanimb"></item>
<item android:drawable="#drawable/activateanimc"></item>
<item android:drawable="#drawable/activateanimc"></item>
<item android:drawable="#drawable/activateanimd"></item>
<item android:drawable="#drawable/activateanime"></item>
<item android:drawable="#drawable/activateanimf"></item>
<item android:drawable="#drawable/activateanimg"></item>
</transition>
How do I animate an image to behave like an animated gif, in place. no rotations or translations here. Using android 2.1+
Are you after a Frame animation? See: here. This will play a standing still animation.
Example from above site:
XML file saved at res/anim/rocket.xml:
<?xml version="1.0" encoding="utf-8"?>
<animation-list xmlns:android="http://schemas.android.com/apk/res/android"
android:oneshot="false">
<item android:drawable="#drawable/rocket_thrust1" android:duration="200" />
<item android:drawable="#drawable/rocket_thrust2" android:duration="200" />
<item android:drawable="#drawable/rocket_thrust3" android:duration="200" />
</animation-list>
To use:
ImageView rocketImage = (ImageView) findViewById(R.id.rocket_image);
rocketImage.setBackgroundResource(R.drawable.rocket_thrust);
rocketAnimation = (AnimationDrawable) rocketImage.getBackground();
rocketAnimation.start();
Just use a view flipper to flip between the images. Just define your in and out animations to be 0seconds long and they should be instantianous. (but use alpha to be sure). View flipper has the benefit of also auto animating and auto starting

I need to design a component for animation rendering. Because you probably are much smarter than me I ask your opinion.How would you do the following design?
More precisely I want to have a horse which can run, stop, jump and dodge.
I can obtain all the frames needed for all these states. For example, I can draw all the frames containing the horse running(f[1] - f[n]). But what if the horse needs to dodge while running on f[k] frame (1
How can I design this type of transitions? What classes would you use? Do I need to draw transitions for every f[k]?
More details if helps: Design will be implemeneted in Android SDK.
Thank you very much!
Please try below code . hope it will work
You need to create animation-list under res/drawable
<?xml version="1.0" encoding="utf-8"?>
<animation-list xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/animationFrame"
android:oneshot="false" >
<item
android:drawable="#drawable/es0"
android:duration="100"/>
<item
android:drawable="#drawable/es1"
android:duration="100"/>
<item
android:drawable="#drawable/es2"
android:duration="100"/>
<item
android:drawable="#drawable/es3"
android:duration="100"/>
<item
android:drawable="#drawable/es4"
android:duration="100"/>
</animation-list>
Write below code in your activity
private AnimationDrawable m_frameAnimation = new AnimationDrawable();
imageView.setBackgroundResource(R.drawable.animationFrame);
m_frameAnimation = (AnimationDrawable) imageView.getBackground();
m_frameAnimation.start();
I am using animation for my button but its too fast when I click the animation happens so fast you can barely see at the moment its just two drawables with a selector.xml state pressed true
How can I so slow the animation just a little bit
You can use android:enterFadeDuration and android:exitFadeDurationto achieve your desired effect.
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android" android:enterFadeDuration="400" android:exitFadeDuration="400">
<item android:drawable="#color/pressed" android:state_pressed="true" />
<item android:drawable="#color/default" />
</selector>
This android:duration="200" is the time in miliseconds that your animation will occur. Go for 500 (0,5 seconds) or more if you want.
I'd like to display a animation with transparent background, on a transparent activity. How can I realize it with Android? I thought about flash, but the user has to have flash installed, right? I'd prefer vector graphics instead of gifs.
Thanks a lot in advance!
Example:
The best way to show an animation is to store them as PNGs and do something like this for an animation, put this in your drawable folder.:
<animation-list xmlns:android="http://schemas.android.com/apk/res/android" android:oneshot="false">
<item android:drawable="#drawable/ant1" android:duration="100" />
<item android:drawable="#drawable/ant2" android:duration="100" />
<item android:drawable="#drawable/ant3" android:duration="100" />
<item android:drawable="#drawable/ant2" android:duration="100" />
</animation-list>
If you want to use vector graphics, then you have to manually switch the images. You could look into svg-android, which is a great way to use simple vector images in Android.
Hey you this library for animation of background image and set theme Theme.Transparent for activity...so you can achieve your requirement This is the link might be usefull...KenBurnsView
i want to create a progressbar in android like that image
i try to use
<animated-rotate xmlns:android="http://schemas.android.com/apk/res/android"
android:drawable="#drawable/loadingicon"
android:pivotX="50%"
android:pivotY="50%" />
but i think it not meet in my requirement
Here is a good example to customize progressbar: http://developer.android.com/reference/android/graphics/drawable/AnimationDrawable.html
U must draw all state of you future progress bar (img1.png, img2.png, img3.png, img4.png). put image to /res/drawable.
pb_animation.xml:
<animation-list android:id="#+id/myprogressrbar" android:oneshot="false">
<item android:drawable="#drawable/img1" android:duration="50" />
<item android:drawable="#drawable/img2" android:duration="50" />
<item android:drawable="#drawable/img3" android:duration="50" />
<item android:drawable="#drawable/img4" android:duration="50" />
</animation-list>
And then, in yor code:
ImageView img = (ImageView)findViewById(R.id.spinning_wheel_image);
img.setBackgroundResource(R.drawable.pb_animation);
AnimationDrawable frameAnimation = (AnimationDrawable) img.getBackground();
frameAnimation.start();
you could use an AnimationDrawable in combination with an ImageView and add a drawable for every state of your loading indicator, but a better way to this, is creating a new Style for a ProgressBar view (by extending de platform default style) and use your AnimationDrawable as loading indicator.
The Android styles are open source, so you can easily find them and extend them for your needs.
Good luck!
What is the best way to design and embed an animation into an android app.
(I'm not talking about transitions and activities in/out animations.)
I can think of 2 ways of doing it:
designing the animation with flash or something similar, export png-sequence with transparent bgs and creating an animation from the images in an xml file (How do I write this kind of xml?)
creating a grid of images with all the frames of the animation that I've created
and save it into one image. than using something like background-position in css in order to move the visible area of the image on each frame enter (By Java code, or by xml)
which of this is better/most common? and how do I implement the solution (if there is a better solution - that would be great).
and what programs do you usually use for this kind of task
(the goal is to achieve something that works like the frog in cut the rope or the birds in angry birds for example)
thanks!
I used simple animation in one project... It's on your first point... A sequence of *.png files in /res/drawable, and *.xml like:
<?xml version="1.0" encoding="utf-8"?>
<animation-list xmlns:android="http://schemas.android.com/apk/res/android"
android:oneshot="true">
<item android:drawable="#drawable/s250" android:duration="200" />
<item android:drawable="#drawable/s251" android:duration="200" />
<item android:drawable="#drawable/s252" android:duration="200" />
<item android:drawable="#drawable/s253" android:duration="200" />
<item android:drawable="#drawable/s254" android:duration="200" />
<item android:drawable="#drawable/s255" android:duration="200" />
<item android:drawable="#drawable/s256" android:duration="200" />
<item android:drawable="#drawable/s257" android:duration="200" />
<item android:drawable="#drawable/s258" android:duration="200" />
</animation-list>
... and source...
final ImageView pygalo = (ImageView) findViewById(R.id.imageanimation);
pygalo.setBackgroundResource(R.anim.animation);
final AnimationDrawable pygaloanimation = (AnimationDrawable) pygalo.getBackground();
pygalo.setOnClickListener(new OnClickListener()
{
#Override
public void onClick(View vp) {
pygaloanimation.stop();
pygaloanimation.start();
}
});
It is very easy to do...
