How do I play an animation through a button that is already set up to play music? (eclipse)

As said in the title, I have already set up a button to play specific music, but then I also want it to activate an animation from an already existing imageview that would play along with it (for my case, sheet music for a piece of music) and then revert back to the original imageview if the button is repressed (stopping the music) or when the song is finished.
The code for the activity with the button is here:
package net.ZachApps.sheetmusicapp;
import android.app.Activity;
import android.media.MediaPlayer;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import android.widget.ImageView;
public class ElDoradoScore extends Activity {
Button btnElDorado;
ImageView imgscore;
MediaPlayer songElDorado;
int playing;
#Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
setContentView(R.layout.eldoradoscore);
btnElDorado = (Button)findViewById(R.id.btnElDorado);
btnElDorado.setOnClickListener(bElDorado);
songElDorado = new MediaPlayer();
songElDorado = MediaPlayer.create(this, R.raw.eldoradoscore);
playing = 0;
}
Button.OnClickListener bElDorado = new Button.OnClickListener(){
#Override
public void onClick(View arg0) {
// TODO Auto-generated method stub
switch(playing){
case 0:
songElDorado.start();
playing=1;
btnElDorado.setText("Stop El Dorado Song");
break;
case 1:
songElDorado.stop();
playing = 0;
btnElDorado.setText("Start El Dorado Song");
break;
}
}
};
}
I have the animation saved as res/anim/score.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/eldoradop1" android:duration="2000" />
<item android:drawable="#drawable/eldoradop2" android:duration="2000" />
<item android:drawable="#drawable/eldoradop3" android:duration="2000" />
<item android:drawable="#drawable/eldoradop4" android:duration="2000" />
<item android:drawable="#drawable/eldoradop5" android:duration="2000" />
<item android:drawable="#drawable/eldoradop6" android:duration="2000" />
<item android:drawable="#drawable/eldoradop7" android:duration="2000" />
<item android:drawable="#drawable/eldoradop8" android:duration="2000" />
<item android:drawable="#drawable/eldoradop9" android:duration="2000" />
<item android:drawable="#drawable/eldoradop10" android:duration="2000" />
<item android:drawable="#drawable/eldoradop11" android:duration="2000" />
</animation-list>
I have tried to look for a way to activate the animation from the button (with the cases), but I haven't found helpful information when I have searched. What should I do from here?
I know there is another way to set it up but I want to know if it is possible from this point of view.

Add another member variable:
AnimationDrawable animation;
Add in the onCreate method:
imgscore = (ImageView)findViewById(R.id.imgscore); // assuming that's the name
imgscore.setBackgroundResource(
R.drawable.your_animation_resource); // I don't know the resource name
animation = (AnimationDrawable)imgscore.getBackground();
Add under case 0 in your OnClickListener's switch statement:
animation.start();
And under case 1:
animation.stop();
Depending on the behavior you desire, you may also want to set the visibility of the ImageView in your OnClickListener.
Edit:
As a side note, you should be sure to call release on the MediaPlayer at an appropriate time (at the very least, in onDestroy), and depending on your intentions, you may need a little more sophisticated treatment to produce the desired behavior.

Show DialogFragment with animation growing from a point

I'm showing a DialogFragment when the user taps on a row in a ListView. I'd like to animate the showing of the dialog so that it grows from the center of the row. A similar effect can be seen when opening a folder from the launcher.
One idea that I've had is a combination of TranslateAnimation and ScaleAnimation. Is there another way?

Being DialogFragment a wrapper for the Dialog class, you should set a theme to your base Dialog to get the animation you want:
public class CustomDialogFragment extends DialogFragment implements OnEditorActionListener
{
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState)
{
return super.onCreateView(inflater, container, savedInstanceState);
}
#Override
public Dialog onCreateDialog(Bundle savedInstanceState)
{
// Set a theme on the dialog builder constructor!
AlertDialog.Builder builder =
new AlertDialog.Builder( getActivity(), R.style.MyCustomTheme );
builder
.setTitle( "Your title" )
.setMessage( "Your message" )
.setPositiveButton( "OK" , new DialogInterface.OnClickListener()
{
#Override
public void onClick(DialogInterface dialog, int which) {
dismiss();
}
});
return builder.create();
}
}
Then you just need to define the theme that will include your desired animation. In styles.xml add your custom theme:
<style name="MyCustomTheme" parent="#android:style/Theme.Panel">
<item name="android:windowAnimationStyle">#style/MyAnimation.Window</item>
</style>
<style name="MyAnimation.Window" parent="#android:style/Animation.Activity">
<item name="android:windowEnterAnimation">#anim/anim_in</item>
<item name="android:windowExitAnimation">#anim/anim_out</item>
</style>
Now add the animation files in the res/anim folder:
( the android:pivotY is the key )
anim_in.xml
<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android">
<scale
android:interpolator="#android:anim/linear_interpolator"
android:fromXScale="0.0"
android:toXScale="1.0"
android:fromYScale="0.0"
android:toYScale="1.0"
android:fillAfter="false"
android:startOffset="200"
android:duration="200"
android:pivotX = "50%"
android:pivotY = "-90%"
/>
<translate
android:fromYDelta="50%"
android:toYDelta="0"
android:startOffset="200"
android:duration="200"
/>
</set>
anim_out.xml
<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android">
<scale
android:interpolator="#android:anim/linear_interpolator"
android:fromXScale="1.0"
android:toXScale="0.0"
android:fromYScale="1.0"
android:toYScale="0.0"
android:fillAfter="false"
android:duration="200"
android:pivotX = "50%"
android:pivotY = "-90%"
/>
<translate
android:fromYDelta="0"
android:toYDelta="50%"
android:duration="200"
/>
</set>
Finally, the tricky thing here is to get your animation grow from the center of each row. I suppose the row is filling the screen horizontally so, on one hand the android:pivotX value will be static. On the other hand, you can't modify the android:pivotY value programmatically.
What I suggest is, you define several animations each of which having a different percentage value on the android:pivotY attribute (and several themes referencing those animations). Then, when the user taps the row, calculate the Y position in percentage of the row on the screen. Knowing the position in percentage, assign a theme to your dialog that has the appropriate android:pivotY value.
It is not a perfect solution but could do the trick for you. If you don't like the result, then I would suggest forgetting the DialogFragment and animating a simple View growing from the exact center of the row.

Check it out this code, it works for me
// Slide up animation
<?xml version="1.0" encoding="utf-8"?> <set xmlns:android="http://schemas.android.com/apk/res/android" >
<translate
android:duration="#android:integer/config_mediumAnimTime"
android:fromYDelta="100%"
android:interpolator="#android:anim/accelerate_interpolator"
android:toXDelta="0" />
</set>
// Slide dowm animation
<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android" >
<translate
android:duration="#android:integer/config_mediumAnimTime"
android:fromYDelta="0%p"
android:interpolator="#android:anim/accelerate_interpolator"
android:toYDelta="100%p" />
</set>
// Style
<style name="DialogAnimation">
<item name="android:windowEnterAnimation">#anim/slide_up</item>
<item name="android:windowExitAnimation">#anim/slide_down</item>
</style>
// Inside Dialog Fragment
#Override
public void onActivityCreated(Bundle arg0) {
super.onActivityCreated(arg0);
getDialog().getWindow()
.getAttributes().windowAnimations = R.style.DialogAnimation;
}

DialogFragment has a public getTheme() method that you can over ride for this exact reason. This solution uses less lines of code:
public class MyCustomDialogFragment extends DialogFragment{
...
#Override
public int getTheme() {
return R.style.MyThemeWithCustomAnimation;
}
}

To get a full-screen dialog with animation, write the following ...
Styles:
<style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
<item name="colorPrimary">#color/colorPrimary</item>
<item name="colorPrimaryDark">#color/colorPrimaryDark</item>
<item name="colorAccent">#color/colorAccent</item>
<item name="actionModeBackground">?attr/colorPrimary</item>
<item name="windowActionModeOverlay">true</item>
</style>
<style name="AppTheme.NoActionBar">
<item name="windowActionBar">false</item>
<item name="windowNoTitle">true</item>
</style>
<style name="AppTheme.NoActionBar.FullScreenDialog">
<item name="android:windowAnimationStyle">#style/Animation.WindowSlideUpDown</item>
</style>
<style name="Animation.WindowSlideUpDown" parent="#android:style/Animation.Activity">
<item name="android:windowEnterAnimation">#anim/slide_up</item>
<item name="android:windowExitAnimation">#anim/slide_down</item>
</style>
res/anim/slide_up.xml
<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android"
android:shareInterpolator="#android:interpolator/accelerate_quad">
<translate
android:duration="#android:integer/config_shortAnimTime"
android:fromYDelta="100%"
android:toYDelta="0%"/>
</set>
res/anim/slide_down.xml
<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android"
android:shareInterpolator="#android:interpolator/accelerate_quad">
<translate
android:duration="#android:integer/config_shortAnimTime"
android:fromYDelta="0%"
android:toYDelta="100%"/>
</set>
Java code:
public class MyDialog extends DialogFragment {
#Override
public int getTheme() {
return R.style.AppTheme_NoActionBar_FullScreenDialog;
}
}
private void showDialog() {
FragmentTransaction fragmentTransaction = getSupportFragmentManager().beginTransaction();
Fragment previous = getSupportFragmentManager().findFragmentByTag(MyDialog.class.getName());
if (previous != null) {
fragmentTransaction.remove(previous);
}
fragmentTransaction.addToBackStack(null);
MyDialog dialog = new MyDialog();
dialog.show(fragmentTransaction, MyDialog.class.getName());
}

In DialogFragment, custom animation is called onCreateDialog. 'DialogAnimation' is custom animation style in previous answer.
public Dialog onCreateDialog(Bundle savedInstanceState)
{
final Dialog dialog = super.onCreateDialog(savedInstanceState);
dialog.getWindow().getAttributes().windowAnimations = R.style.DialogAnimation;
return dialog;
}

Use decor view inside onStart in your dialog fragment
#Override
public void onStart() {
super.onStart();
final View decorView = getDialog()
.getWindow()
.getDecorView();
decorView.animate().translationY(-100)
.setStartDelay(300)
.setDuration(300)
.start();
}

If you want to work over APIs you have to do inside your DialogFragemnt->onStart and not inside onCreateDialog
#Override
public void onStart()
{
if (getDialog() == null)
{
return;
}
getDialog().getWindow().setWindowAnimations(
R.style.DlgAnimation);
super.onStart();
}

Note: This is just a complement to other answers.
No matter which the solutions you pick you might have the same problem as me.
I need to UNINSTALL the game from my development device before installing the new version for the animation changes to take effect.
I am not sure why but I guess it has to do with the optimized deployment on Android studio not recognizing the changes.

Have you looked at Android Developers Training on Zooming a View? Might be a good starting point.
You probably want to create a custom class extending DialogFragment to get this working.
Also, take a look at Jake Whartons NineOldAndroids for Honeycomb Animation API compatibility all the way back to API Level 1.

Add this code on values anim
<scale
android:duration="#android:integer/config_longAnimTime"
android:fromXScale="0.2"
android:fromYScale="0.2"
android:toXScale="1.0"
android:toYScale="1.0"
android:pivotX="50%"
android:pivotY="50%"/>
<alpha
android:fromAlpha="0.1"
android:toAlpha="1.0"
android:duration="#android:integer/config_longAnimTime"
android:interpolator="#android:anim/accelerate_decelerate_interpolator"/>
call on styles.xml
<style name="DialogScale">
<item name="android:windowEnterAnimation">#anim/scale_in</item>
<item name="android:windowExitAnimation">#anim/scale_out</item>
</style>
On java code: set Onclick
public void onClick(View v) {
fab_onclick(R.style.DialogScale, "Scale" ,(Activity) context,getWindow().getDecorView().getRootView());
// Dialogs.fab_onclick(R.style.DialogScale, "Scale");
}
setup on method:
alertDialog.getWindow().getAttributes().windowAnimations = type;

Why animated drawable doesn't appear

I want to create animated drawable from 14 png images.
I added the 14 images to all drawable- folders, and created a animated-list like below, but nothing appear, what is the problem ?
circle.xml:
<animation-list xmlns:android="http://schemas.android.com/apk/res/android">
<item android:drawable="#drawable/f1" android:duration="50" />
<item android:drawable="#drawable/f2" android:duration="50" />
<item android:drawable="#drawable/f3" android:duration="50" />
<item android:drawable="#drawable/f4" android:duration="50" />
<item android:drawable="#drawable/f5" android:duration="50" />
<item android:drawable="#drawable/f6" android:duration="50" />
<item android:drawable="#drawable/f7" android:duration="50" />
<item android:drawable="#drawable/f8" android:duration="50" />
<item android:drawable="#drawable/f9" android:duration="50" />
<item android:drawable="#drawable/f10" android:duration="50" />
<item android:drawable="#drawable/f11" android:duration="50" />
<item android:drawable="#drawable/f12" android:duration="50" />
<item android:drawable="#drawable/f13" android:duration="50" />
<item android:drawable="#drawable/f14" android:duration="50" />
</animation-list>
layout xml:
<?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" >
<Button
android:id="#+id/btnStart"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Start" />
<ImageView
android:id="#+id/imgCircle"
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
</LinearLayout>
java code:
package pit.opensource.animation;
import android.app.Activity;
import android.graphics.drawable.AnimationDrawable;
import android.os.Bundle;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.ImageView;
public class CircleAnimationActivity extends Activity {
/** Called when the activity is first created. */
Button btnStart;
ImageView imgCircle;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
btnStart = (Button)findViewById(R.id.btnStart);
imgCircle = (ImageView) findViewById(R.id.imgCircle);
imgCircle.setBackgroundResource(R.drawable.circle);
AnimationDrawable ani = (AnimationDrawable) imgCircle.getBackground();
ani.start();
btnStart.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View arg0) {
// ani.start();
}
});
}
}

The background should be animation, you should put circle.xml to res/anim, and change
imgCircle.setBackgroundResource(R.drawable.circle);
to
imgCircle.setBackgroundResource(R.anim.circle);
Try following code to start the animation
imgCircle.post(new Runnable() {
#Override
public void run() {
AnimationDrawable ani = (AnimationDrawable) imgCircle.getBackground();
ani.start();
}
});
or implement move the animation start to onWindowFocusChanged
public void onWindowFocusChanged(boolean flag) {
super.onWindowFocusChanged(flag);
AnimationDrawable anim = (AnimationDrawable) imgCircle.getBackground();
anim.start();
}

There could be third reasons.
First reason is OutOfMemoryError. You need to compress your images.
Solution
Second reason is android:oneshot parameter in your circle.xml. This animation runs for just 14 frames. By setting the android:oneshot attribute of the list to true, it will cycle just once then stop and hold on the last frame. If it is set false then the animation will loop.
Change
<animation-list xmlns:android="http://schemas.android.com/apk/res/android">
with
<animation-list xmlns:android="http://schemas.android.com/apk/res/android" android:oneshot="true">
Third Reason is start() method called on the AnimationDrawable cannot be called during the onCreate() method of your Activity, because the AnimationDrawable is not yet fully attached to the window.
Change your MainActivity.java with this code:
package pit.opensource.animation;
import android.app.Activity;
import android.graphics.drawable.AnimationDrawable;
import android.os.Bundle;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.ImageView;
public class CircleAnimationActivity extends Activity {
Button btnStart;
ImageView imgCircle;
AnimationDrawable ani;
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
imgCircle = (ImageView) findViewById(R.id.imgCircle);
imgCircle.setBackgroundResource(R.drawable.circle);
ani = (AnimationDrawable) imgCircle.getBackground();
addListenerOnButton();
}
public void addListenerOnButton() {
btnStart = (Button)findViewById(R.id.btnStart);
btnStart.setOnClickListener(new OnClickListener() {
public void onClick(View arg0) {
ani.start();
}
});
}
}

Android AnimationDrawable starts, and when done hangs on first frame

I'm trying to get the AnimationDrawable on my Android app to repeat.
I configured the android:oneshot on false. (tried both with java and with XML)
Still, whenever the animation is played, once it's done, it goes back to the first frame, and stops
This is my XML file
<?xml version="1.0" encoding="utf-8"?>
<animation-list xmlns:android="http://schemas.android.com/apk/res/android" android:id="#+id/network_scanning" android:oneshot="false">
<item android:drawable="#drawable/network_wireless_0" android:duration="300" />
<item android:drawable="#drawable/network_wireless_1" android:duration="300" />
<item android:drawable="#drawable/network_wireless_2" android:duration="300" />
<item android:drawable="#drawable/network_wireless_3" android:duration="300" />
<item android:drawable="#drawable/network_wireless_4" android:duration="300" />
</animation-list>
and this is the code to start the animation:
#Override
public void onWindowFocusChanged(boolean hasFocus)
{
super.onWindowFocusChanged(hasFocus);
LinearLayout network = (LinearLayout) findViewById(R.id.wifi_anim);
AnimationDrawable anim = (AnimationDrawable) network.getBackground();
if (hasFocus)
{
anim.setOneShot(false);
anim.setCallback(network);
anim.setVisible(true, true);
anim.start();
}
}

hi you can get solution from here
http://docs.mono-android.net/Android.Graphics.Drawables.AnimationDrawable

Can I change the Android startActivity() transition animation?

I am starting an activity and would rather have a alpha fade-in for startActivity(), and a fade-out for the finish(). How can I go about this in the Android SDK?

Starting from API level 5 you can call overridePendingTransition immediately to specify an explicit transition animation:
startActivity();
overridePendingTransition(R.anim.hold, R.anim.fade_in);
or
finish();
overridePendingTransition(R.anim.hold, R.anim.fade_out);

See themes on android: http://developer.android.com/guide/topics/ui/themes.html.
Under themes.xml there should be android:windowAnimationStyle where you can see the declaration of the style in styles.xml.
Example implementation:
<style name="AppTheme" parent="...">
...
<item name="android:windowAnimationStyle">#style/WindowAnimationStyle</item>
</style>
<style name="WindowAnimationStyle">
<item name="android:windowEnterAnimation">#android:anim/fade_in</item>
<item name="android:windowExitAnimation">#android:anim/fade_out</item>
</style>

In the same statement in which you execute finish(), execute your animation there too. Then, in the new activity, run another animation. See this code:
fadein.xml
<set xmlns:android="http://schemas.android.com/apk/res/android"
android:fillAfter="true">
<alpha android:fromAlpha="1.0"
android:toAlpha="0.0"
android:duration="500"/> //Time in milliseconds
</set>
In your finish-class
private void finishTask() {
if("blabbla".equals("blablabla"){
finish();
runFadeInAnimation();
}
}
private void runFadeInAnimation() {
Animation a = AnimationUtils.loadAnimation(this, R.anim.fadein);
a.reset();
LinearLayout ll = (LinearLayout) findViewById(R.id.yourviewhere);
ll.clearAnimation();
ll.startAnimation(a);
}
fadeout.xml
<set xmlns:android="http://schemas.android.com/apk/res/android"
android:fillAfter="true">
<alpha android:fromAlpha="0.0"
android:toAlpha="1.0"
android:duration="500"/>
</set>
In your new Activity-class you create a similiar method like the runFadeAnimation I wrote and then you run it in onCreate and don't forget to change the resources id to fadeout.

Use overridePendingTransition
startActivity();
overridePendingTransition(R.anim.fadein, R.anim.fadeout);
fadein.xml
<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android">
<alpha xmlns:android="http://schemas.android.com/apk/res/android"
android:interpolator="#android:anim/accelerate_interpolator"
android:fromAlpha="0.0" android:toAlpha="1.0" android:duration="500" />
</set>
fadeout.xml
<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android">
<alpha xmlns:android="http://schemas.android.com/apk/res/android"
android:interpolator="#android:anim/anticipate_interpolator"
android:fromAlpha="1.0" android:toAlpha="0.0" android:duration="500" />
</set>

For fadeIn and fadeOut, only add this after super.onCreate(savedInstanceState) in your new Activity class. You don't need to create something else (No XML, no anim folder, no extra function).
overridePendingTransition(R.anim.abc_fade_in,R.anim.abc_fade_out);

If you always want to the same transition animation for the activity
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
overridePendingTransition(android.R.anim.fade_in, android.R.anim.fade_out);
#Override
protected void onPause() {
super.onPause();
if (isFinishing()) {
overridePendingTransition(android.R.anim.fade_in, android.R.anim.fade_out);
}
}

You can simply create a context and do something like below:-
private Context context = this;
And your animation:-
((Activity) context).overridePendingTransition(R.anim.abc_slide_in_bottom,R.anim.abc_slide_out_bottom);
You can use any animation you want.

I wanted to use the styles.xml solution, but it did not work for me with activities.
Turns out that instead of using android:windowEnterAnimation and android:windowExitAnimation, I need to use the activity animations like this:
<style name="ActivityAnimation.Vertical" parent="">
<item name="android:activityOpenEnterAnimation">#anim/enter_from_bottom</item>
<item name="android:activityOpenExitAnimation">#anim/exit_to_bottom</item>
<item name="android:activityCloseEnterAnimation">#anim/enter_from_bottom</item>
<item name="android:activityCloseExitAnimation">#anim/exit_to_bottom</item>
<item name="android:windowEnterAnimation">#anim/enter_from_bottom</item>
<item name="android:windowExitAnimation">#anim/exit_to_bottom</item>
</style>
Which I then reference in my theme:
<style name="AppTheme">
...
<item name="android:windowAnimationStyle">#style/ActivityAnimation.Vertical</item>
...
</style>
Also, for some reason this only worked from Android 8 and above.
I added the following code to my BaseActivity, to fix it for the API levels below:
override fun finish() {
super.finish()
setAnimationsFix()
}
/**
* The activityCloseExitAnimation and activityCloseEnterAnimation properties do not work correctly when applied from the theme.
* So in this fix, we retrieve them from the theme, and apply them.
* #suppress Incorrect warning: https://stackoverflow.com/a/36263900/1395437
*/
#SuppressLint("ResourceType")
private fun setAnimationsFix() {
// Retrieve the animations set in the theme applied to this activity in the manifest..
var activityStyle = theme.obtainStyledAttributes(intArrayOf(android.R.attr.windowAnimationStyle))
val windowAnimationStyleResId = activityStyle.getResourceId(0, 0)
activityStyle.recycle()
// Now retrieve the resource ids of the actual animations used in the animation style pointed to by
// the window animation resource id.
activityStyle = theme.obtainStyledAttributes(windowAnimationStyleResId, intArrayOf(android.R.attr.activityCloseEnterAnimation, android.R.attr.activityCloseExitAnimation))
val activityCloseEnterAnimation = activityStyle.getResourceId(0, 0)
val activityCloseExitAnimation = activityStyle.getResourceId(1, 0)
activityStyle.recycle()
overridePendingTransition(activityCloseEnterAnimation, activityCloseExitAnimation);
}

// CREATE anim
// CREATE animation,animation2 xml // animation like fade out
Intent myIntent1 = new Intent(getApplicationContext(), Attend.class);
Bundle bndlanimation1 = ActivityOptions.makeCustomAnimation(getApplicationContext(),
R.anim.animation, R.anim.animation2).toBundle();
startActivity(myIntent1, bndlanimation1);

Most of the answers are pretty correct, but some of them are deprecated such as when using R.anim.hold and some of them are just elaboratig the process.
So, you can use:
startActivity(intent);
overridePendingTransition(android.R.anim.fade_in, android.R.anim.fade_out);
