how to modify an animation after loading from xml resource in android

after I load an animation from res/anim I need to only change the startOffset of it.
programmatically, it doesn't work. but from xml it's ok.
#JvmStatic
#BindingAdapter("animation", "animationDelay", requireAll = false)
fun setAnimation(view: View, animId: Int, delay: Long?) {
AnimationUtils.loadAnimation(view.context, animId).apply {
if (delay != null) startOffset = delay // doesn't work
view.startAnimation(this)
}
}
<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android"
android:interpolator="#android:anim/accelerate_decelerate_interpolator"
android:startOffset="2000"> <!-- works -->
<translate
android:duration="1500"
android:fromYDelta="100%"
android:toYDelta="0" />
<alpha
android:duration="1000"
android:fromAlpha="0"
android:startOffset="500"
android:toAlpha="1" />
</set>
so how should I achieve this? or should I create a separate animation file for each of delay values?

Animate fragment transitions with using Navigation drawer or Toolbar menu

I have a Navigation drawer and Toolbar menu where I can go to another fragment. I used this to navigate:
override fun onNavigationItemSelected(item: MenuItem): Boolean
{
drawerLayout.close()
return NavigationUI.onNavDestinationSelected(
item,
findNavController(R.id.navHostFragment)
)
}
How I can add custom animation while switching fragments?
It is Answer your own question. I have faced this problem and couldn't find any answer which would work 100% well in my case so maybe this will help somebody.

This is how the overridden method onNavigationItemSelected should looks:
override fun onNavigationItemSelected(item: MenuItem): Boolean
{
drawerLayout.close()
// this part checks if current fragment is the same as destination
return if (findNavController(R.id.navHostFragment).currentDestination?.id != item.itemId)
{
val builder = NavOptions.Builder()
.setLaunchSingleTop(true)
.setEnterAnim(R.anim.enter_left_to_right)
.setExitAnim(R.anim.exit_right_to_left)
.setPopEnterAnim(R.anim.popenter_right_to_left)
.setPopExitAnim(R.anim.popexit_left_to_right)
// this part set proper pop up destination to prevent "looping" fragments
if (item.order and Menu.CATEGORY_SECONDARY == 0)
{
var startDestination: NavDestination? =
findNavController(R.id.navHostFragment).graph
while (startDestination is NavGraph)
{
val parent = startDestination
startDestination = parent.findNode(parent.startDestination)
}
builder.setPopUpTo(
startDestination!!.id,
false
)
}
val options = builder.build()
return try
{
findNavController(R.id.navHostFragment).navigate(item.itemId, null, options)
true
}
catch (e: IllegalArgumentException) // couldn't find destination, do nothing
{
false
}
}
else
{
false
}
}
This method prevents going to current, selected fragments. So when a user is in the Fragment A and in the Navigation drawer again selects Fragment A nothing will happen, Navigation drawer will just hide.
This method also prevents "looping" fragments, there could be only one fragment on the stack which was selected from the Navigation drawer or Toolbar menu. E.g. in the navigation drawer is Fragment A and Fragment B. The user is in Fragment Home then go to Fragment A and next to Fragment B. If a user clicks back button app will go back to Fragment Home, not to the Fragment A. Also, instead of finding startDestination in a while loop, it is possible to use R.id.homeFragment. If anyone wants to allow "looping" fragments just delete this part in code.
I have tested this solution and it seems to work well but of course there can be something which doesn't work exactly as it should.
If someone wants simple animation with fade in/fade out and vertical translation:
R.anim.enter_left_to_right
<set xmlns:android="http://schemas.android.com/apk/res/android">
<translate
android:duration="#integer/fragment_anim_time"
android:fromXDelta="-100%"
android:fromYDelta="0%"
android:toXDelta="0%"
android:toYDelta="0%" />
<alpha
android:duration="#integer/fragment_anim_time"
android:fromAlpha="0.5"
android:toAlpha="1" />
</set>
R.anim.exit_right_to_left
<set xmlns:android="http://schemas.android.com/apk/res/android">
<translate
android:duration="#integer/fragment_anim_time"
android:fromXDelta="0%"
android:fromYDelta="0%"
android:toXDelta="100%"
android:toYDelta="0%" />
<alpha
android:duration="#integer/fragment_anim_time"
android:fromAlpha="1"
android:toAlpha="0.5" />
</set>
R.anim.popenter_right_to_left
<set xmlns:android="http://schemas.android.com/apk/res/android">
<translate
android:duration="#integer/fragment_anim_time"
android:fromXDelta="100%"
android:fromYDelta="0%"
android:toXDelta="0%"
android:toYDelta="0%" />
<alpha
android:duration="#integer/fragment_anim_time"
android:fromAlpha="0.5"
android:toAlpha="1" />
</set>
R.anim.popexit_left_to_right
<set xmlns:android="http://schemas.android.com/apk/res/android">
<translate
android:duration="#integer/fragment_anim_time"
android:fromXDelta="0%"
android:fromYDelta="0%"
android:toXDelta="-100%"
android:toYDelta="0%" />
<alpha

</set>
res/values/integers.xml

Is there a way to slide between Activities without the black gap?

I'm trying to create an Android app, and switch between activities with a slide, when the previous activity slides out to the right, and the new activity comes in the left.
I can do somethibg like this, with:
Intent intent = new Intent(getContext(), NextActivity.class);
startActivity(intent);
overridePendingTransition(R.anim.in_ltr, R.anim.out_ltr);
Where the in_ltr.xml is:
<?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="700"
/>
</set>
And the out_ltr.xml is:
<?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="0"
android:toXDelta="100%p"
android:duration="500"
/>
</set>
It's almost perfect, but a small black gap appers between the two activity during the animation. You can see it here on YouTube.
I've tried anything I found in the Google in the last hour, but nothing seems to remove that gap. Is it possible to remove that gap?
Thanks!

Try to set Alpha with translate effect....
Try This...
slide_in.xml
<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android"
android:interpolator="#android:interpolator/accelerate_cubic">
<translate
android:fromXDelta="0%"
android:toXDelta="100%"
android:duration="400" />
<alpha
android:fromAlpha="1.0"
android:toAlpha="0.3"
android:duration="500" />
</set>

Add this two file in res/anim folder.
slide_in.xml
<?xml version="1.0" encoding="utf-8"?>
<translate
xmlns:android="http://schemas.android.com/apk/res/android"
android:duration="#android:integer/config_longAnimTime"
android:fromXDelta="100%p"
android:toXDelta="0%p">
</translate>
slide_out.xml
<?xml version="1.0" encoding="utf-8"?>
<translate
xmlns:android="http://schemas.android.com/apk/res/android"
android:duration="#android:integer/config_longAnimTime"
android:fromXDelta="0%p"
android:toXDelta="-100%p">
</translate>
And write the following code in onCreate() method of next activity that you pass through the Intent.
overridePendingTransition(r.anim.slide_in, R.anim.slide_out);
hope it will remove your space

Try this: create a RootActivity.java and extend it in your activity.
import android.app.Activity;
import android.os.Bundle;
public class RootActivity extends Activity {
int onStartCount = 0;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
onStartCount = 1;
if (savedInstanceState == null) // 1st time
{
this.overridePendingTransition(R.anim.anim_slide_in_left,
R.anim.anim_slide_out_left);
} else // already created so reverse animation
{
onStartCount = 2;
}
}
#Override
protected void onStart() {
// TODO Auto-generated method stub
super.onStart();
if (onStartCount > 1) {
this.overridePendingTransition(R.anim.anim_slide_in_right,
R.anim.anim_slide_out_right);
} else if (onStartCount == 1) {
onStartCount++;
}
}
}
add these animations to anim folder:
anim_slide_in_left.xml
<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android" >
<translate
android:duration="600"
android:fromXDelta="100%"
android:toXDelta="0%" >
</translate>
</set>
anim_slide_in_right.xml
<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android" >
<translate
android:duration="600"
android:fromXDelta="-100%"
android:toXDelta="0%" >
</translate>
</set>
anim_slide_out_right.xml
<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android" >
<translate
android:duration="600"
android:fromXDelta="0%"
android:toXDelta="100%" >
</translate>
</set>
anim_slide_out_left.xml
<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android" >
<translate
android:duration="600"
android:fromXDelta="0%"
android:toXDelta="-100%" >
</translate>
</set>

Try to add below item into your AppTheme
<item name="android:windowIsTranslucent">true</item>

Sorry guys, I was very, very stupid.
I changed the duration to the same amount of time, and the gap disappeared.

Fragment transaction animation: slide in and slide out

I've check some tutorials for animate transaction between fragments. I've used this method for animation and it works:
fragmentTransaction.setCustomAnimations(android.R.anim.slide_in_left,
android.R.anim.slide_out_right);
But I want to invert this animation: old fragment slide out to the left, and new fragment slide in to the right, but no value of R.anim file seems to be useful for my scope.
How can I do it?

UPDATE For Android v19+ see this link via #Sandra
You can create your own animations. Place animation XML files in res > anim
enter_from_left.xml
<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android"
android:shareInterpolator="false">
<translate
android:fromXDelta="-100%p" android:toXDelta="0%"
android:fromYDelta="0%" android:toYDelta="0%"
android:duration="#android:integer/config_mediumAnimTime"/>
</set>
enter_from_right.xml
<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android"
android:shareInterpolator="false">
<translate
android:fromXDelta="100%p" android:toXDelta="0%"
android:fromYDelta="0%" android:toYDelta="0%"
android:duration="#android:integer/config_mediumAnimTime" />
</set>
exit_to_left.xml
<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android"
android:shareInterpolator="false">
<translate
android:fromXDelta="0%" android:toXDelta="-100%p"
android:fromYDelta="0%" android:toYDelta="0%"
android:duration="#android:integer/config_mediumAnimTime"/>
</set>
exit_to_right.xml
<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android"
android:shareInterpolator="false">
<translate
android:fromXDelta="0%" android:toXDelta="100%p"
android:fromYDelta="0%" android:toYDelta="0%"
android:duration="#android:integer/config_mediumAnimTime" />
</set>
you can change the duration to short animation time
android:duration="#android:integer/config_shortAnimTime"
or long animation time
android:duration="#android:integer/config_longAnimTime"
USAGE
(note that the order in which you call methods on the transaction matters. Add the animation before you call .replace, .commit):
FragmentTransaction transaction = supportFragmentManager.beginTransaction();
transaction.setCustomAnimations(R.anim.enter_from_right, R.anim.exit_to_left, R.anim.enter_from_left, R.anim.exit_to_right);
transaction.replace(R.id.content_frame, fragment);
transaction.addToBackStack(null);
transaction.commit();

There is three way to transaction animation in fragment.
Transitions
So need to use one of the built-in Transitions, use the setTranstion()
method:
getSupportFragmentManager()
.beginTransaction()
.setTransition( FragmentTransaction.TRANSIT_FRAGMENT_OPEN )
.show( m_topFragment )
.commit()
Custom Animations
You can also customize the animation by using the setCustomAnimations() method:
getSupportFragmentManager()
.beginTransaction()
.setCustomAnimations( R.anim.slide_up, 0, 0, R.anim.slide_down)
.show( m_topFragment )
.commit()
slide_up.xml
<?xml version="1.0" encoding="utf-8"?>
<objectAnimator
xmlns:android="http://schemas.android.com/apk/res/android"
android:interpolator="#android:anim/accelerate_decelerate_interpolator"
android:propertyName="translationY"
android:valueType="floatType"
android:valueFrom="1280"
android:valueTo="0"
android:duration="#android:integer/config_mediumAnimTime"/>
slide_down.xml
<?xml version="1.0" encoding="utf-8"?>
<objectAnimator
xmlns:android="http://schemas.android.com/apk/res/android"
android:interpolator="#android:anim/accelerate_decelerate_interpolator"
android:propertyName="translationY"
android:valueType="floatType"
android:valueFrom="0"
android:valueTo="1280"
android:duration="#android:integer/config_mediumAnimTime"/>
Multiple Animations
Finally, It's also possible to kick-off multiple fragment animations
in a single transaction. This allows for a pretty cool effect where
one fragment is sliding up and the other slides down at the same time:
getSupportFragmentManager()
.beginTransaction()
.setCustomAnimations( R.anim.abc_slide_in_top, R.anim.abc_slide_out_top ) // Top Fragment Animation
.show( m_topFragment )
.setCustomAnimations( R.anim.abc_slide_in_bottom, R.anim.abc_slide_out_bottom ) // Bottom Fragment Animation
.show( m_bottomFragment )
.commit()
To more detail you can visit URL
Note:- You can check animation according to your requirement because above may be have issue.

slide_in_down.xml
<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android">
<translate
android:duration="#android:integer/config_longAnimTime"
android:fromYDelta="0%p"
android:toYDelta="100%p" />
</set>
slide_in_up.xml
<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android">
<translate
android:duration="#android:integer/config_longAnimTime"
android:fromYDelta="100%p"
android:toYDelta="0%p" />
</set>
slide_out_down.xml
<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android">
<translate
android:duration="#android:integer/config_longAnimTime"
android:fromYDelta="-100%"
android:toYDelta="0"
/>
</set>
slide_out_up.xml
<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android">
<translate
android:duration="#android:integer/config_longAnimTime"
android:fromYDelta="0%p"
android:toYDelta="-100%p"
/>
</set>
direction = down
activity.getSupportFragmentManager()
.beginTransaction()
.setCustomAnimations(R.anim.slide_out_down, R.anim.slide_in_down)
.replace(R.id.container, new CardFrontFragment())
.commit();
direction = up
activity.getSupportFragmentManager()
.beginTransaction()
.setCustomAnimations(R.anim.slide_in_up, R.anim.slide_out_up)
.replace(R.id.container, new CardFrontFragment())
.commit();

I have same issue, i used simple solution
1)create sliding_out_right.xml in anim folder
<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android">
<translate android:fromXDelta="0" android:toXDelta="-50%p"
android:duration="#android:integer/config_mediumAnimTime"/>
<alpha android:fromAlpha="1.0" android:toAlpha="0.0"
android:duration="#android:integer/config_mediumAnimTime" />
</set>
2) create sliding_in_left.xml in anim folder
<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android">
<translate android:fromXDelta="50%p" android:toXDelta="0"
android:duration="#android:integer/config_mediumAnimTime"/>
<alpha android:fromAlpha="0.0" android:toAlpha="1.0"
android:duration="#android:integer/config_mediumAnimTime" />
</set>
3) simply using fragment transaction setCustomeAnimations() with two custom xml and two default xml for animation as follows :-
fragmentTransaction.setCustomAnimations(R.anim.sliding_in_left, R.anim.sliding_out_right, android.R.anim.slide_in_left, android.R.anim.slide_out_right );

This is another solution which I use:
public class CustomAnimator {
private static final String TAG = "com.example.CustomAnimator";
private static Stack<AnimationEntry> animation_stack = new Stack<>();
public static final int DIRECTION_LEFT = 1;
public static final int DIRECTION_RIGHT = -1;
public static final int DIRECTION_UP = 2;
public static final int DIRECTION_DOWN = -2;
static class AnimationEntry {
View in;
View out;
int direction;
long duration;
}
public static boolean hasHistory() {
return !animation_stack.empty();
}
public static void reversePrevious() {
if (!animation_stack.empty()) {
AnimationEntry entry = animation_stack.pop();
slide(entry.out, entry.in, -entry.direction, entry.duration, false);
}
}
public static void clearHistory() {
animation_stack.clear();
}
public static void slide(final View in, View out, final int direction, long duration) {
slide(in, out, direction, duration, true);
}
private static void slide(final View in, final View out, final int direction, final long duration, final boolean save) {
ViewGroup in_parent = (ViewGroup) in.getParent();
ViewGroup out_parent = (ViewGroup) out.getParent();
if (!in_parent.equals(out_parent)) {
return;
}
int parent_width = in_parent.getWidth();
int parent_height = in_parent.getHeight();
ObjectAnimator slide_out;
ObjectAnimator slide_in;
switch (direction) {
case DIRECTION_LEFT:
default:
slide_in = ObjectAnimator.ofFloat(in, "translationX", parent_width, 0);
slide_out = ObjectAnimator.ofFloat(out, "translationX", 0, -out.getWidth());
break;
case DIRECTION_RIGHT:
slide_in = ObjectAnimator.ofFloat(in, "translationX", -out.getWidth(), 0);
slide_out = ObjectAnimator.ofFloat(out, "translationX", 0, parent_width);
break;
case DIRECTION_UP:
slide_in = ObjectAnimator.ofFloat(in, "translationY", parent_height, 0);
slide_out = ObjectAnimator.ofFloat(out, "translationY", 0, -out.getHeight());
break;
case DIRECTION_DOWN:
slide_in = ObjectAnimator.ofFloat(in, "translationY", -out.getHeight(), 0);
slide_out = ObjectAnimator.ofFloat(out, "translationY", 0, parent_height);
break;
}
AnimatorSet animations = new AnimatorSet();
animations.setDuration(duration);
animations.playTogether(slide_in, slide_out);
animations.addListener(new Animator.AnimatorListener() {
#Override
public void onAnimationCancel(Animator arg0) {
}
#Override
public void onAnimationEnd(Animator arg0) {
out.setVisibility(View.INVISIBLE);
if (save) {
AnimationEntry ae = new AnimationEntry();
ae.in = in;
ae.out = out;
ae.direction = direction;
ae.duration = duration;
animation_stack.push(ae);
}
}
#Override
public void onAnimationRepeat(Animator arg0) {
}
#Override
public void onAnimationStart(Animator arg0) {
in.setVisibility(View.VISIBLE);
}
});
animations.start();
}
}
The usage of class. Let's say you have two fragments (list and details fragments)as shown below
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/ui_container"
android:layout_width="match_parent"
android:layout_height="match_parent" >
<FrameLayout
android:id="#+id/list_container"
android:layout_width="match_parent"
android:layout_height="match_parent" />
<FrameLayout
android:id="#+id/details_container"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:visibility="gone" />
</FrameLayout>
Usage
View details_container = findViewById(R.id.details_container);
View list_container = findViewById(R.id.list_container);
// You can select the direction left/right/up/down and the duration
CustomAnimator.slide(list_container, details_container,CustomAnimator.DIRECTION_LEFT, 400);
You can use the function CustomAnimator.reversePrevious();to get the previous view when the user pressed back.

Have the same problem with white screen during transition from one fragment to another. Have navigation and animations set in action in navigation.xml.
Background in all fragments the same but white blank screen. So i set navOptions in fragment during executing transition
//Transition options
val options = navOptions {
anim {
enter = R.anim.slide_in_right
exit = R.anim.slide_out_left
popEnter = R.anim.slide_in_left
popExit = R.anim.slide_out_right
}
}
.......................
this.findNavController().navigate(SampleFragmentDirections.actionSampleFragmentToChartFragment(it),
options)
It worked for me. No white screen between transistion. Magic )

For me the only way I was able to get rid of the white background on the animation is if I changed to a DialogFragment instead of a Fragment and added the following code:
Created the following styles:
<style name="WindowSlideInAndOutAnimation">
<item name="android:windowEnterAnimation">#anim/slide_in_bottom</item>
<item name="android:windowExitAnimation">#anim/slide_out_top</item>
</style>
<style name="AppFullScreenDialogTransparentTitleBar" parent="Theme.MaterialComponents.Light.Dialog">
<item name="android:windowBackground">#android:color/transparent</item>
<item name="android:windowNoTitle">true</item>
<item name="android:windowIsFloating">false</item>
<item name="colorPrimaryDark">#android:color/transparent</item>
</style>
Then reference these styles in the dialog fragment as such:
override fun getTheme() = R.style.AppFullScreenDialogTransparentTitleBar
override fun onViewCreated(view: View, savedInstanceState: Bundle?) {
super.onViewCreated(view, savedInstanceState)
dialog?.window?.setWindowAnimations(R.style.WindowSlideInAndOutAnimation)
//rest of code on view created here
}
Then I just navigate to the fragment as normal via the navigation component (also note to change the type in the navigation xml file for the fragment to be dialog)

Transition android fragment slide up

I have a fragment that is to replace another fragment. I want to specify the animation. But the animation is ignored.
transaction.replace(R.id.my_fragment, newFrag);
transaction.addToBackStack(null);
transaction.setCustomAnimations(R.anim.slide_in_up, R.anim.slide_out_up);
slide_in_up
<?xml version="1.0" encoding="utf-8"?>
<translate xmlns:android="http://schemas.android.com/apk/res/android"
android:duration="#android:integer/config_longAnimTime"
android:fromYDelta="0%p"
android:toYDelta="100%p" />
slide_out_up
<?xml version="1.0" encoding="utf-8"?>
<translate xmlns:android="http://schemas.android.com/apk/res/android"
android:duration="#android:integer/config_longAnimTime"
android:fromYDelta="100%p"
android:toYDelta="0%p" />
All I am really trying to achieve is for the new fragment to slide in from the bottom. My animations are ignored. What is the code missing?

transaction.setCustomAnimations(R.anim.slide_in_up, R.anim.slide_out_up);
transaction.addToBackStack(null);
transaction.replace(R.id.my_fragment, newFrag);
slide_in_up
<?xml version="1.0" encoding="utf-8"?>
<translate xmlns:android="http://schemas.android.com/apk/res/android"
android:duration="#android:integer/config_longAnimTime"
android:fromYDelta="100%p"
android:toYDelta="0%p" />
slide_out_up
<?xml version="1.0" encoding="utf-8"?>
<translate xmlns:android="http://schemas.android.com/apk/res/android"
android:duration="#android:integer/config_longAnimTime"
android:fromYDelta="0%p"
android:toYDelta="-100%p" />

It's been some time since this question was asked but here is an answer for other people coming here:
e1da is right insofar as that setCustomAnimation() call has to be called before replace(). Otherwise the animation will not show.
The second problem is that you probably are using native fragments that cannot be animated with the view animations.
Use the following files:
slide_in_up.xml
<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android"
android:fillAfter="true" >
<objectAnimator
android:duration="500"
android:propertyName="y"
android:valueFrom="1280"
android:valueTo="0"
android:valueType="floatType" />
</set>
slide_out_up.xml
<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android"
android:fillAfter="true" >
<objectAnimator
android:duration="500"
android:propertyName="y"
android:valueFrom="0"
android:valueTo="-1280"
android:valueType="floatType" />
</set>
A little explanation:
You have to differentiate between view animation for support fragments on one hand and property animation for native fragments on the other hand.
View animation:
Is the pre-android 3.0 way to animate views. Sample code for this is the slide_in.xml and slide_up.xml by user3093402
<?xml version="1.0" encoding="utf-8"?>
<translate xmlns:android="http://schemas.android.com/apk/res/android"
android:duration="#android:integer/config_longAnimTime"

It is worth mentioning you cannot animate fragments with view animation. The exception to this are fragments from the support library (android.support.v4.app.Fragment).
Property animation
This is the way to animate objects after android 3.0. It is also declared as .xml files but makes use of the "valueAnimator" tag (objectAnimator extends valueAnimator). Examples are in the answer to the question.
This is the way how native fragments (android.app.Fragment) can be animated.

Hope this helps,

EDIT: As pointed out by Raphael Royer-Rivard the fixed screen size is bad practice. It would be better to use a constant from the OS like in
getWindowManager().getDefaultDisplay().getMetrics(metrics).xdpi
(see DisplayMetrics). But I haven't done any Android development for some time so I don't know which one.

code for slide_in_up :
<?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%p"
android:toYDelta="0%p" />
</set>
code for slide_in_down:
<?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:toYDelta="100%p" />
</set>
code for slide_out_up:
<?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:fromXDelta="0"
android:toYDelta="100%" />
</set>
code for slide_out_down:
<?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:fromXDelta="0"
android:toYDelta="-100%" />
</set>
and after that in your activity or fragment set animation like below:
Fragment fragment = new Fragment();
FragmentTransaction transaction = getSupportFragmentManager().beginTransaction();
transaction.setCustomAnimations(R.anim.slide_in_up, R.anim.slide_in_down, R.anim.slide_out_down, R.anim.slide_out_up);
transaction.replace(container, fragment).commit();

Currently with android.transition this is as simple as fragment.enterTransition = Slide() or fragment.enterTransition = Fade()
Note: Min version L.

R.anim will not work there but R.animator wil do.
for example
transaction.setCustomAnimations(android.R.animator.fade_in, android.R.animator.fade_out);

This answer is written in Kotlin. For sake of the example, I'm just hiding or showing it based on it's current isHidden attribute. I'm using androidx.transition.Slide
Link: https://developer.android.com/reference/androidx/transition/Slide
val frag = supportFragmentManager.findFragmentById(R.id.frag_id_from_xml_layout)
frag?.let {
val ft = supportFragmentManager.beginTransaction()
frag.enterTransition = Slide()
frag.exitTransition = Slide()
if (frag.isHidden) ft.show(frag) else ft.hide(frag)
ft.commit()
}

here is complete working example
Pressing the button toggles between 2 fragments A and B (by slide animation right to left). The fragments are just stupid text (AAAAAA and BBBBB) with different backgrounds.
MainActivity.java
package com.example.slidetrans;

import android.widget.Button;
public class MainActivity extends Activity {
boolean showingA = true;
Button button;
A a;
B b;
private void incarnate(FragmentManager fm){
int layoutId = R.id.frame;
boolean fragmentWasNull = false;
Fragment f = fm.findFragmentById(layoutId);
if (f == null){
if (showingA){
f = a = new A();
} else {
f = b = new B();
}
fragmentWasNull = true;
}
if (fragmentWasNull){
FragmentTransaction ft = fm.beginTransaction();
ft.add(layoutId, showingA ? a : b, "main").commit();
}
}
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
FragmentManager fm = getFragmentManager();
incarnate(fm);
button = (Button)findViewById(R.id.button);
OnClickListener listener = new OnClickListener() {
#Override
public void onClick(View v) {
FragmentManager fm = getFragmentManager();
FragmentTransaction transaction = fm.beginTransaction();
transaction.setCustomAnimations(R.anim.in, R.anim.out);
transaction.replace(R.id.frame, showingA ? new B() : new A()).commit();
showingA = !showingA;
button.setText(showingA ? "slide in B" : "slide in A");
}
};
button.setOnClickListener(listener);
}
}

else return getX();
}

float newWidth = (width > 0) ? (xFraction * width) : -9999;
setX(newWidth);
