Define certain enter and exit transitions for specific views in activity

I am adding activity transitions using this documentation. I understand that I can define enter and exit transitions for the entire activity, such as explode.
However, what if I want to animate certain views of the entering activity differently? For example, if I have one view on the top half of the layout and one at the bottom of the layout, I may want to use a downwards slide transition on the top view and an upward slide animation on the bottom view. Is this possible to set?
I can think of using scene animations (documented here) and bringing in the elements from the sides of an empty view, but my layout is complicated and I am iterating it often, so keeping track of two different layouts for it is not really ideal.
Thanks!

Finally got it! The idea is to create custom transition in xml and to set there targets:
<?xml version="1.0" encoding="utf-8"?>
<transitionSet
xmlns:android="http://schemas.android.com/apk/res/android"
android:transitionOrdering="together">
<slide
android:slideEdge="top">
<targets>
<target android:targetId="#id/toolbar"/>
</targets>
</slide>
<slide
android:slideEdge="bottom">
<targets>
<target android:targetId="#id/text"/>
</targets>
</slide>
</transitionSet>

To apply animation to desired view like button, textview, imageview, etc check this http://www.androidhive.info/2013/06/android-working-with-xml-animations/
Create four XML files for animation:
/res/anim/anim_alpha.xml
<?xml version="1.0" encoding="utf-8"?>

Apply two alternate rotations to a View in Android

I'd like to apply 2 alternate rotation animations to a View. Each rotation should start after the click on the same View.
The result I'm looking for is:
the user clicks on the View and it rotates from 0° to 135°
the user clicks again on the View and it rotates from 135° to 0° (to the initial state)
The problem is that, when the user performs the second click, the Button resets to the initial aspect before starting the animation correctly.
I'm targeting Android APIs<11 so I'm using the startAnimation() method. The animations are applied to a Button view defined as follows:
<Button
android:id="#+id/button"
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
The animations are the following
rotate_cw.xml (0° to 135° rotation):
<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android"
android:fillAfter="true">
<rotate
android:duration="300"
android:fromDegrees="0"
android:pivotX="50%"
android:pivotY="50%"
android:toDegrees="135" />
</set>
rotate_ccw.xml (135° to 0° rotation):
<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android">
<rotate
android:duration="300"
android:fromDegrees="135"
android:pivotX="50%"
android:pivotY="50%"
android:toDegrees="0"/>
</set>
The animations are then applied in this way, where flag is a boolean global variable:
Button b = (Button) findViewById(R.id.button);
b.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
if (flag) {
Animation a = AnimationUtils.loadAnimation(this, R.anim.rotate_cw);
b.startAnimation(a);
} else {
Animation a = AnimationUtils.loadAnimation(this, R.anim.rotate_ccw);
b.startAnimation(a);
}
flag = !flag;
}
});
Am I missing anything?
Thanks in advance for your help.

How to get the animated view

here is xml file：
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="150dp"
android:layout_height="match_parent">
<Button
android:id="#+id/textview"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="#string/hello_world" />
here is java code
private Button text;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
text = (Button)findViewById(R.id.textview);
text.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
text.startAnimation(getScaleAnimation());
}
});
}
private ScaleAnimation getScaleAnimation(){
ScaleAnimation animation = new ScaleAnimation(1f,1.2f,1f,1.2f,Animation.RELATIVE_TO_SELF,0.5f,Animation.RELATIVE_TO_SELF,0.5f);
animation.setDuration(1000);
animation.setFillAfter(true);
return animation;
}
I am performing a simple ScaleAnimation on a Button.Is there any way I can get the animated view?

Just open anim folder inside res folder. Create an xml file. Then you need to create set tag. Inside of it, you can create scale tag.
Here is an example:
<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android"
android:interpolator="#android:anim/accelerate_interpolator">
<scale
android:fromXScale="0.5"
android:toXScale="2"
android:fromYScale="0.5"
android:toYScale="2"
android:pivotX="50%"
android:pivotY="50%"
android:duration="5000"
/>
</set>
Note: do not forget to include xmlns:android declaration.
Now, inside of onCreate method or wherever you want, just put following. I am animating(scaling) a button itself when it is clicked:
Button but = (Button) findViewById(R.id.button1);
but.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
Animation anim = AnimationUtils.loadAnimation(AnimationActivity.this, R.anim.animation);
but.startAnimation(anim);
}
});
EDIT:
in case you want to rotate it while scaling, you can put following inside of the xml file:
<rotate
android:fromDegrees="0"
android:toDegrees="360"
android:pivotX="50%"
android:pivotY="50%"
android:duration="5000"
/>
Hope this helps.

Use this way
Create an xml inside /res/anim folder and put the below code into it.
<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="schemas.android.com/apk/res/android"
android:interpolator="#android:anim/linear_interpolator">
<scale android:fromXScale="0.0" android:fromYScale="0.0"
android:toXScale="1.0" android:toYScale="1.0"
android:duration="700" android:fillBefore="false" />
</set>
Place the below code inside the java file:
Animation scaleAnimation
= AnimationUtils.loadAnimation(this, R.anim.logoanimation);
Btn.startAnimation(scaleAnimation);
logoanimation is the name of my animation xml file.

How can I animate a custom view (ImageView) programmatically?

I want to animate a custom view programmatically. I want it to only animate in the position where it is declare in the xml file, and I don't want it to mess the layout. Also this animation is affected by other factor so the android Animation class is out of the question.
I have test this sample tutorial and watch this videos. My problem is that most tutorial is for animating a sprite into a canvas where you will trace your sprite's location.
How can you animate the custom view without affecting layout and without using the Android Animation class?
Edited:
The custom view will act as a animated-gif and will toggle another set of frames whenever an event activates it.

you can create animation XML and apply that animation from program to your ImageView check following example
you can start animation for your customized view just call viewobject.startAnimation(animationobject);
animation.xml
<set xmlns:android="http://schemas.android.com/apk/res/android"
android:shareInterpolator="false">
<scale
android:interpolator="#android:anim/accelerate_decelerate_interpolator"
android:fromXScale="1.0"
android:toXScale="1.4"
android:fromYScale="1.0"
android:toYScale="0.6"
android:pivotX="50%"
android:pivotY="50%"
android:fillAfter="false"
android:duration="700" />
<set
android:interpolator="#android:anim/accelerate_interpolator"
android:startOffset="700">
<scale
android:fromXScale="1.4"
android:toXScale="0.0"
android:fromYScale="0.6"
android:toYScale="0.0"
android:pivotX="50%"
android:pivotY="50%"
android:duration="400" />
<rotate
android:fromDegrees="0"
android:toDegrees="-45"
android:toYScale="0.0"
android:pivotX="50%"
android:pivotY="50%"
android:duration="400" />
</set>
your main.xml
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
>
<TextView
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="#string/hello"
/>
<ImageView android:id="#+id/ImageView01" android:layout_width="wrap_content" android:layout_height="wrap_content"></ImageView>
</LinearLayout>
then your activity class myActivity.java
public class myActivity extends Activity {
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
ImageView image = (ImageView) findViewById(R.id.ImageView01);
//create animation class object
Animation hyperspaceJump =
AnimationUtils.loadAnimation(this, R.anim.hyperspace_jump);
//start animation for image
image.startAnimation(hyperspaceJump);
}
}

If you want "frame by frame" animation that just "runs" like an animated gif, you can follow:
drawable-animation official tutorial.
Quoting from the tutorial:
<animation-list xmlns:android="http://schemas.android.com/apk/res/android"
android:oneshot="true">
<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>
and in your code
AnimationDrawable rocketAnimation;
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
ImageView rocketImage = (ImageView) findViewById(R.id.rocket_image);
rocketImage.setBackgroundResource(R.drawable.rocket_thrust);
rocketAnimation = (AnimationDrawable) rocketImage.getBackground();
}
public boolean onTouchEvent(MotionEvent event) {
if (event.getAction() == MotionEvent.ACTION_DOWN) {
rocketAnimation.start();
return true;
}
return super.onTouchEvent(event);
}

Moving an image through a linearlayout

I'm developing an Android 2.2 application.
I want to move an image from left side of the screen to the right side of the screen.
How can I do that? I've read that I have to add this image to a ListView or to a GridView to setup this animation.
UPDATE
I've created the following files:
anim/translate_right
<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android"
android:interpolator="#android:anim/accelerate_decelerate_interpolator">
<translate
android:fromXDelta="-100%p"
android:toXDelta="0"
android:duration="5000" />
</set>
anim/ship_layout_controller
<?xml version="1.0" encoding="utf-8"?>
<layoutAnimation xmlns:android="http://schemas.android.com/apk/res/android"
android:delay="10%"
android:animationOrder="reverse"
android:animation="#anim/translate_right" />
layout/startpage
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical">
<TextView
android:id="#+id/appNameTextView"
android:text="#string/app_name"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:layout_marginTop="40px"/>
<Button
android:id="#+id/PlayButton"
android:text="#string/play"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:layout_marginTop="40px"/>
<AbsoluteLayout
android:layout_width="fill_parent"
android:layout_height="wrap_content"
xmlns:android="http://schemas.android.com/apk/res/android">
<ImageView
android:id="#+id/greekShip"
android:persistentDrawingCache="animation|scrolling"
android:layoutAnimation="#anim/ship_layout_controller"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="#drawable/greekship"
android:maxWidth="176px"
android:maxHeight="87px"
android:layout_x="-300px"/>
</AbsoluteLayout>
</LinearLayout>
StartActivity.java
public class StartActivity extends Activity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.startpage);
}
#Override
protected void onResume() {
super.onResume();
ImageView ship = (ImageView)findViewById(R.id.greekShip);
ship.startAnimation(AnimationUtils.loadAnimation(this, R.anim.translate_right));
}
}
But it doesn't work.

Please take a look at the Animation class, specifically the Tween Animation, more specifically the Translate element. Create an animation file in your project then apply this animation to your image. For example, this animation would move an object from the center of the screen to the right side.
<?xml version="1.0" encoding="utf-8"?>
<translate
xmlns:android="http://schemas.android.com/apk/res/android"
android:toXDelta="100%p"
android:fromXDelta="0%"
android:duration="300"
android:fillEnabled="true"
android:fillAfter="true">
</translate>
EDIT: To apply this animation to a Button, a TextView, an ImageView, etc.
ImageView imageView = (ImageView) findViewById(R.id.myImageView);
Animation exitAnimation = AnimationUtils.loadAnimation(this, R.anim.exit_animation);
imageView.startAnimation(exitAnimation);

you have to use Translate Animation. For example, this animation would move an image from Left side of the screen to the right side of the screen.
The AnimationActivity is
listener = new AnimationListener() {
#Override
public void onAnimationStart(Animation animation) {}
#Override
public void onAnimationRepeat(Animation animation) {}
#Override
public void onAnimationEnd(Animation animation) {
System.out.println("End Animation!");
//load_animations();
}
};
}
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
if (v==button)
{
moveLefttoRight = new TranslateAnimation(0, 200, 0, 0);
moveLefttoRight.setDuration(1000);
moveLefttoRight.setFillAfter(true);
my_image.startAnimation(moveLefttoRight);
}
}
}
xml code is
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context=".MainActivity" >
<ImageView
android:id="#+id/diceid"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="#drawable/dice"/>
</LinearLayout>
and anim file is
<?xml version="1.0" encoding="utf-8"?>
<rotate
xmlns:android="http://schemas.android.com/apk/res/android"
android:fromDegrees="0"
android:toDegrees="360"
android:pivotX="50%"
android:pivotY="50%"
android:duration="2000"
android:repeatMode="reverse"
android:repeatCount="infinite"
android:startOffset="0"
/>
may be this is the answer what you are searching.

I would check your source again. Maybe it's out of context. But the easiest way to do this is to use a Translate animation that originates from the Image's starting place and translates it to the other side of the screen. After that is done I usually register an animation callback so that I can update the true position of the image after the animation is over. hope that helps.

Or is it the Gallery that you are looking for?
