Activity transition animations don't work

I'm currently working on a dark theme transition by restarting the activity, but I stumbled upon a problem: the transitions don't work and I have no idea why.
The code below is the theme resources I currently use:
<style name="Theme.TestApp" parent="Theme.MaterialComponents.DayNight.NoActionBar">
<!-- Primary brand color. -->
<item name="colorPrimary">#color/grey_light</item>
<item name="colorPrimaryVariant">#color/primary_light</item>
<item name="colorOnPrimary">#color/on_primary_light</item>
<!-- Secondary brand color. -->
<item name="colorSecondary">#color/teal_200</item>
<item name="colorSecondaryVariant">#color/teal_700</item>
<item name="colorOnSecondary">#color/white</item>
<!-- Customize your theme here. -->
<item name="android:statusBarColor">#color/bar</item>
<item name="background">#color/grey_light</item>
<item name="android:textColor">#color/list_text</item>
<item name="android:windowSplashScreenBackground" tools:targetApi="s">#color/primary_light</item>
<item name="android:windowAnimationStyle">#style/WindowAnimation</item>
</style>
<style name="WindowAnimation">
<item name="android:windowEnterAnimation">#android:anim/fade_in</item>
<item name="android:windowExitAnimation">#android:anim/fade_out</item>
</style>
And this is the code I use to restart the activity:
myswitch.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
#Override
public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
if (isChecked) {
AppCompatDelegate.setDefaultNightMode(AppCompatDelegate.MODE_NIGHT_YES);
restart();
}else {
AppCompatDelegate.setDefaultNightMode(AppCompatDelegate.MODE_NIGHT_NO);
restart();
}
}
});
}
public void restart () {
Intent i = new Intent(getApplicationContext(), Settings.class);
startActivity(i);
finish();
}
}

Apparently, creating my own animations solved my problem.
fade_in.xml:
<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android"
android:fillAfter="true">
<alpha
android:interpolator="#android:anim/accelerate_interpolator"
android:fromAlpha="0.0"
android:toAlpha="1.0"
android:duration="500" />
</set>
fade_out.xml:
<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android"
android:fillAfter="true">
<alpha
android:interpolator="#android:anim/accelerate_interpolator"
android:fromAlpha="1.0"
android:toAlpha="0.0"
android:duration="500" />
</set>

Repeat animation when button is press

I have an attack animation that I want to repeat animation whenever the button for attack is clicking all I can come up is one show of animation only,when the button is press again the animation won't repeat again
here is my animation code
imgAttack = (ImageView) findViewById(R.id.imgAttack);
imgAttack.setBackgroundResource(R.drawable.attack_anim);
attackanimation=(AnimationDrawable)imgAttack.getBackground();
btnAtk.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
press=+1;
MaxHealth-=100;
swordAtk.start();
attackanimation.start();
health.setProgress(MaxHealth);
if(MaxHealth==0) {
health.setProgress(0);
Gold=Gold+1;
txtGold.setText("Gold:"+Gold);
SharedPreferences prefs = RpgActivity.this.getSharedPreferences(getString( R.string.PREF_FILE),MODE_PRIVATE);
SharedPreferences.Editor editor = prefs.edit();
editor.putInt(getString(R.string.SDR),Gold);
editor.apply();
}
}
});
here is my xml for attack_anim.xml
<?xml version="1.0" encoding="utf-8"?>
<animation-list xmlns:android="http://schemas.android.com/apk/res/android"
>
<item android:drawable="#drawable/attak0001" android:duration="100" />
<item android:drawable="#drawable/attak0002" android:duration="100" />
<item android:drawable="#drawable/attak0003" android:duration="100" />
<item android:drawable="#drawable/attak0004" android:duration="100" />
<item android:drawable="#drawable/attak0005" android:duration="100" />
<item android:drawable="#drawable/attak0006" android:duration="100" />
<item android:drawable="#drawable/attak0007" android:duration="100" />
</animation-list>

You can do something like this before attackAnimation.start()
attackAnimation.stop();
attackAnimation.selectDrawable(0);
and after that write attackAnimation.start().

using android animation-list

I'm having a little trouble getting an animated loading spinner to work for a splash page. Nothing shows up when I try to run the following code. Any suggestions? It seems that quite a few people have issues with this on google but I do not understand why mine is failing to work. Thanks!
animationloader.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/loadingspinner1" android:duration="200" />
<item android:drawable="#drawable/loadingspinner2" android:duration="200" />
<item android:drawable="#drawable/loadingspinner3" android:duration="200" />
<item android:drawable="#drawable/loadingspinner4" android:duration="200" />
<item android:drawable="#drawable/loadingspinner5" android:duration="200" />
<item android:drawable="#drawable/loadingspinner6" android:duration="200" />
<item android:drawable="#drawable/loadingspinner7" android:duration="200" />
<item android:drawable="#drawable/loadingspinner8" android:duration="200" />
<item android:drawable="#drawable/loadingspinner9" android:duration="200" />

<item android:drawable="#drawable/loadingspinner11" android:duration="200" />
<item android:drawable="#drawable/loadingspinner12" android:duration="200" />
</animation-list>
SplashScreen.java
package com.secure.inmatecanteen;
import android.app.Activity;
import android.graphics.drawable.AnimationDrawable;
import android.os.Bundle;
import android.widget.ImageView;
public class SplashScreen extends Activity {
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.splashscreen);
//Beginning the loading animation as we attempt to verify registration with SIP
ImageView ivLoader = (ImageView) findViewById(R.id.IVloadinganimation);
ivLoader.setBackgroundResource(R.anim.animationloader);
AnimationDrawable frameAnimation = (AnimationDrawable) ivLoader.getBackground();
frameAnimation.start();
}
}
splashscreen.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="horizontal"
android:background="#android:color/white" >
<ImageView
android:id="#+id/iclogo"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:src="#drawable/iclogo"
android:adjustViewBounds="true"
/>
<ImageView

android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:adjustViewBounds="true"
/>
</LinearLayout>

Solved my own problem, You cannot start animations in the oncreate. It has to be in an onclick listener or inside a runnable.

I think the most elegant and versatile option is to extend from the ImageView class:
public class Loader extends ImageView {
public Loader(Context context, AttributeSet attrs, int defStyle) {
super(context, attrs, defStyle);
init();
}
public Loader(Context context, AttributeSet attrs) {
super(context, attrs);
init();
}
public Loader(Context context) {
super(context);
init();
}
private void init() {
setBackgroundResource(R.drawable.loader);
final AnimationDrawable frameAnimation = (AnimationDrawable) getBackground();
post(new Runnable(){
public void run(){
frameAnimation.start();
}
});
}
}
The loader.xml located in the drawable folder:
<?xml version="1.0" encoding="utf-8"?>
<animation-list xmlns:android="http://schemas.android.com/apk/res/android" >
<item android:drawable="#drawable/loader_1" android:duration="50" />
<item android:drawable="#drawable/loader_2" android:duration="50" />
<item android:drawable="#drawable/loader_3" android:duration="50" />
<item android:drawable="#drawable/loader_4" android:duration="50" />
.....
</animation-list>
Now include in your views something as simple as this:
<com.yourpackage.Loader
android:layout_width="wrap_content"
android:layout_height="wrap_content" />

You can play/start animation from onWindowFocusChanged(boolean hasFocus) method.

Don't set image resource in xml code.
My XML is:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:gravity="center"
android:keepScreenOn="true"
android:id="#+id/splashLayout"
android:background="#color/colorPrimary"
android:layout_height="match_parent">
<ImageView
android:layout_width="230dp"
android:layout_height="230dp"
android:id="#+id/iv_splash"
android:layout_marginTop="-80dp"
android:layout_centerVertical="true"
android:layout_centerHorizontal="true" />
</RelativeLayout>
In Activity i do
public class SplashActivity extends Activity {
ImageView iv_splash;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_splash);
iv_splash=(ImageView)findViewById(R.id.iv_splash);
iv_splash.setBackgroundResource(R.drawable.splash);
final AnimationDrawable progressAnimation =(AnimationDrawable)iv_splash.getBackground();
progressAnimation.start();
}
}
Drawable file
<?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/logo" android:duration="400"/>
<item android:drawable="#drawable/logo1" android:duration="400"/>
</animation-list>
It's Working Good :)

Within this handler the animation is not fully attached to the window, so the animations can’t be started; instead, this is usually done as a result to user action (such as a button press) or within the onWindowFocusChangedhandler.

<item android:drawable="#drawable/ic_covert_f11" android:duration="90"/>
</animation-list>
My MainActivty.java
Always remember to use Runnable to start the animation
public class MainActivity extends AppCompatActivity {
AnimationDrawable progressAnimation;
ImageView imageView;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
imageView = (ImageView)findViewById(R.id.animation_imageview);
progressAnimation = (AnimationDrawable)imageView.getDrawable();
progressAnimation.setCallback(imageView);
progressAnimation.setVisible(true, true);
imageView.post(new Starter());
}
class Starter implements Runnable {
public void run() {
progressAnimation.start();
}
}
}
Works Perfectly Good Luck :)

Elegant solution - create your own Animated View which will follow life-cycle rules.
public class AnimatedImageView extends android.support.v7.widget.AppCompatImageView {
public AnimatedImageView(Context context, AttributeSet attrs) {
super(context, attrs);
setImageDrawable(ContextCompat.getDrawable(
context, R.drawable.animated_icon));
}
#Override
protected void onAttachedToWindow() {
// It's important to note that the 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.
super.onAttachedToWindow();
AnimationDrawable tapAnimation = (AnimationDrawable) getDrawable();
tapAnimation.start();
}
}
here is animated_icon.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/tap_icon_1" android:duration="500" />
<item android:drawable="#drawable/tap_icon_2" android:duration="500" />
</animation-list>

My animation is not starting?

I am trying a simple frame by frame animation. My animation works on button tap, but I want it should start when the activity starts or load . I have tried onWindowFocusChanged() method also to start animation as per told in docs. I think i am making silly mistake. Anyone has idea.
public class FirstActivity extends Activity implements OnClickListener {
/** Called when the activity is first created. */
Button btnalarm;
AnimationDrawable AniFrame;
ImageView images;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
images=(ImageView)findViewById(R.id.myImageView);
images.setBackgroundResource(R.drawable.demo_animation);
AniFrame = (AnimationDrawable)images.getBackground();
}
#Override
public void onWindowFocusChanged(boolean hasFocus) {
super.onWindowFocusChanged(hasFocus);
Log.v("in focus", "in focus");
AniFrame.start();
}
demo_animation.xml file---->
<animation-list
xmlns:android="http://schemas.android.com/apk/res/android"
android:oneshot="false">
<item android:drawable="#drawable/a" android:duration="50" />
<item android:drawable="#drawable/b" android:duration="50" />
<item android:drawable="#drawable/c" android:duration="50" />
<item android:drawable="#drawable/d" android:duration="50" />
<item android:drawable="#drawable/e" android:duration="50" />
<item android:drawable="#drawable/f" android:duration="50" />
<item android:drawable="#drawable/h" android:duration="50" />
<item android:drawable="#drawable/i" android:duration="50" />
<item android:drawable="#drawable/j" android:duration="50" />
<item android:drawable="#drawable/k" android:duration="50" />
</animation-list>

Add
AniFram.start() to the end of your onCreate().
Also inflate your R.layout.main.
Example:
LinearLayout layout = (LinearLayout)findViewById(R.id.main);
layout.startAnimation(AniFrame);
Also check your logcat for problems.
EDIT:
Check out this from the Docs Should help alot.
Animating a drawable

Just use anther thread.It will work fine.
public void onCreate(Bundle savedInstanceState) {
//your code
//At last of onCreate add these lines
images.post(new MyAnimation());
}
class MyAnimation implements Runnable{
#Override
public void run(){
AniFrame.start();
}
}
now it will work,just check it.

Try to use setCallback just before you start the animation as following:
AniFrame.setCallback(images);

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();
}
}
