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.

I have anim file
<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android"
android:duration="60000"
android:fillAfter="true"
android:interpolator="#android:anim/linear_interpolator"
android:shareInterpolator="false" >
<rotate
android:startOffset="0"
android:fromDegrees="0"
android:pivotX="50%"
android:pivotY="50%"
android:toDegrees="360" />
</set>
and I want animation to start immediately. But is starts after 2-3 sec delay. What can be the reason?
Its working properly in my code. So there are no error in XML. Please check your Java. My Java code is:
void startAnim() {
view.clearAnimation();
Animation anim= AnimationUtils.loadAnimation(MainActivity.this, R.anim.anim);
view.startAnimation(anim);
}
private ImageView logo;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
logo=(ImageView)findViewById(R.id.logo);
Animation myanim = AnimationUtils.loadAnimation(this,R.anim.anim);
logo.startAnimation(myanim);
}
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

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.
I'm trying to do a rotating image animation.
I need to rotate an icon around itself just like they do in a progressbar, but what I'm getting is an image rotating around a circle.
Here is my animation code
<?xml version="1.0" encoding="utf-8"?>
<rotate
xmlns:android="http://schemas.android.com/apk/res/android"
android:fromDegrees="0"
android:toDegrees="360"
android:interpolator="#android:anim/linear_interpolator"
android:pivotX="50%"
android:pivotY="50%"
android:duration="2500"
android:repeatCount="infinite"
android:repeatMode="restart"
/>
Where am I going wrong in here?
Thanks
This is the source code for the layout main.xml:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent" >
<Button
android:id="#+id/testButton"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="animationText"
android:onClick="AnimClick"/>
<ImageView
android:id="#+id/testImage"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerInParent="true"
android:contentDescription="image_desc"
android:scaleType="fitCenter"
android:src="#drawable/cat2" />
</RelativeLayout>
To implement the rotation animation, we can define the animation by XML or Java code. If we want to write the animation in the xml, we need to create an animation xml file under /res/anim folder. Here, we create a xml file named rotate_around_center_point.xml
<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android"
android:shareInterpolator="false" >
<rotate
android:duration="2500"
android:interpolator="#android:anim/linear_interpolator"
android:pivotX="50%"
android:pivotY="50%"
android:repeatCount="infinite"
android:repeatMode="restart"
android:toDegrees="360" />
</set>
and this is my Activity:
public class MainActivity extends Activity implements OnClickListener {
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Button btn = (Button) findViewById(R.id.testButton);
btn.setOnClickListener(this);
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.activity_main, menu);
return true;
}
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
ImageView animationTarget = (ImageView) this.findViewById(R.id.testImage);
Animation animation = AnimationUtils.loadAnimation(this, R.anim.rotate_around_center_point);
animationTarget.startAnimation(animation);
}
}
You could try with the following code, rather than doing it in XML:
RotateAnimation rotate = new RotateAnimation(0, 360,
Animation.RELATIVE_TO_SELF, 0.5f, Animation.RELATIVE_TO_SELF,
0.5f);
rotate.setDuration(4000);
rotate.setRepeatCount(Animation.INFINITE);
yourView.setAnimation(rotate);
Well I got where I was wrong. I gave padding to my image which caused it to move aside a little every time it rotated.
Anyhow I removed the padding and now it's working just fine.
Add the following xml in the animation folder
<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android"
android:shareInterpolator="false"
android:duration="4000"
android:fromdegrees="0"
android:pivotx="50%"
android:pivoty="50%"
android:todegrees="360"
android:toyscale="0.0">
</set>
Hope this will help you..

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);
}
