Continue the program after the end of the animation android studio

I made an animation (ObjectAnimator)for a text view it work correctly but i have a question.
I wanna know is there any method that i can use immediately after animation duration finished ?
(I mean a method like onFinish when we use CountDownTimer)
I want the rest of methods and codes I have in app run when animation finished.Is there a solution for that?
ObjectAnimator deltaXAnimation = ObjectAnimator.ofFloat(winMassage,"scaleX",1f,1.5f);
deltaXAnimation.setDuration(300);
deltaXAnimation.start();
ObjectAnimator deltaYAnimation = ObjectAnimator.ofFloat(winMassage,"scaleY",1f,1.5f);
deltaYAnimation.setDuration(300);
deltaYAnimation.start();

HI there are proper callback methods in which you get Animation Start and end Listeners
ObjectAnimator deltaXAnimation =
ObjectAnimator.ofFloat(winMassage,"scaleX",1f,1.5f);
deltaXAnimation.setDuration(300);
deltaXAnimation.start();
deltaXAnimation.addListener(new Animator.AnimatorListener() {
#Override
public void onAnimationStart(Animator animator) {
}
#Override
public void onAnimationEnd(Animator animator) {
}
#Override
public void onAnimationCancel(Animator animator) {
}
#Override
public void onAnimationRepeat(Animator animator) {
}
});

Below code might be understand well, creating a listener for ObjectAnimator
ObjectAnimator deltaXAnimation =
ObjectAnimator.ofFloat(winMassage,"scaleX",1f,1.5f);
deltaXAnimation.setDuration(300);
deltaXAnimation.start();
anim.setAnimationListener(new Animation.AnimationListener() {
public void onAnimationStart(Animation a) {
//
}
public void onAnimationRepeat(Animation a) {
}
public void onAnimationEnd(Animation a) {
}
});
We can go also to your ObjectAnimator
Handler handler = new Handler();
handler.postDelayed(new Runnable() {
#Override
public void run() {
//stop animation after 5 seconds
deltaXAnimation.cancel();
}
}, 5000); //5000 equals to 5seconds
}
Hope this might help you

How to time an animation in android

I am animating a loader on start up. How can I work around it so that instead of using ontouch listener to stop the timer, I use a time of say like 3 seconds? Here is my code:
private void showdiag() {
loader = findViewById(R.id.loader);
logo= loader.findViewById(R.id.logo);
logo.setAnimation(AnimationUtils.loadAnimation(this,R.anim.rotate));
loader.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
loader.setVisibility(View.GONE);
}
});
}

You can use View.postDelayed() to run some action after a set delay:
private void showdiag() {
loader = findViewById(R.id.loader);
logo = loader.findViewById(R.id.logo);
logo.setAnimation(AnimationUtils.loadAnimation(this, R.anim.rotate));
loader.postDelayed(new Runnable() {
#Override
public void run() {
loader.setVisibility(View.GONE);
}
}, 3000);
}

logo.getAnimation().setAnimationListener(new Animation.AnimationListener() {
#Override public void onAnimationStart(Animation animation) {
}
#Override public void onAnimationEnd(Animation animation) {
loader.setVisibility(View.GONE);
}
#Override public void onAnimationRepeat(Animation animation) {
}
});

Please try following code.
logo.getAnimation().setAnimationListener(new Animation.AnimationListener() {
#Override public void onAnimationStart(Animation animation) {
}
#Override public void onAnimationEnd(Animation animation) {
loader.postDelayed(new Runnable() {
#Override
public void run() {
loader.setVisibility(View.GONE);
}
}, 3000);
}
#Override public void onAnimationRepeat(Animation animation) {
}
});

Animation doesn't get called inside postDelayed run()

I have a linearlayout that I want it to be animated after 3 seconds delay using Handler.
After 3 seconds have passed, it doesn't even execute the animation, nor did it enter the AnimationListener's methods.
Here is how I do it:
loginBox.setVisibility(View.GONE);
new Handler().postDelayed(new Runnable() {
#Override
public void run() {
Animation animTranslate = AnimationUtils.loadAnimation(getApplicationContext(),
R.anim.translate);
animTranslate.setAnimationListener(new Animation.AnimationListener() {
#Override
public void onAnimationStart(Animation animation) {
}
#Override
public void onAnimationEnd(Animation animation) {
loginBox.setVisibility(View.VISIBLE);
Animation animFade = AnimationUtils.loadAnimation(getApplicationContext(), R.anim.fade);
loginBox.startAnimation(animFade);
}
#Override
public void onAnimationRepeat(Animation animation) {
}
});
btnContinue.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Intent i = new Intent(getApplicationContext(), MainActivity.class);
startActivity(i);
finish();
}
});
}
}, 3000);
The run() method works fine when I click btnContinue.
How can I make it work?

you forgot to call
loginBox.startAnimation(animTranslate)
and probably you want loginBox.setVisibility(View.VISIBLE); before starting the TranslateAnimation

Delay while restart of animation

I'm using value animator to animate a image view. I want to add a delay in Animation listener, i.e in "onAnimationRepeat()". How to accomplish this?

Maybe try something like this:
public class Test {
private int repeatNumber == 0;
public void startAnimation() {
Animation animation = AnimationUtils.loadAnimation(this, R.anim.fade_in);
animation.setAnimationListener(new AnimationListener() {
#Override
public void onAnimationStart(Animation animation) {Log.i("start", "start");}
#Override
public void onAnimationEnd(Animation animation) {Log.i("end", "end");}
#Override
public void onAnimationRepeat(Animation animation) {
Test.this.repeatNumber++;
Handler handler = new Handler();
handler.postDelayed(new Runnable() {
#Override
public void run() {
Test.this.startAnimation();
}, 30000 );
}
textView.startAnimation(animation);
}
}

DialogFragment animation of layout and "Attempting to destroy the window while drawing!" error

I have a DialogFragment which has some animations of some of the layouts inside its view.
When I dismiss the dialog, I want to perform an animation and when the animation has ended, perform the dismiss operation.
Step1:
Call the fragment from my activity:
myDialog.show(getSupportFragmentManager(), "");
Step 2:
After the user had completed the job with the dialog, he presses a button. That button calls an animation and after that I want the dialog to disappear:
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
View layout = inflater.inflate(R.layout.my_layout, null);
layMain = (LinearLayout) layout.findViewById(R.id.layMain);
TextView btnCancel = (TextView) layout.findViewById(R.id.btnCancel);
btnCancel.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View arg0) {
final Animation anim = AnimationUtils.loadAnimation(getActivity(), R.anim.translate_to_bottom);
anim.setAnimationListener(new AnimationListener() {
#Override
public void onAnimationStart(Animation animation) {
}
#Override
public void onAnimationRepeat(Animation animation) {
}
#Override
public void onAnimationEnd(Animation animation) {
dismiss();
}
});
layMain.startAnimation(anim);
}
});
.....
When the animations ends, the dialog gets dismissed but I get this error on logcat
E/ViewRootImpl(25507): Attempting to destroy the window while drawing!
E/ViewRootImpl(25507): window=android.view.ViewRootImpl#427348e0,
title=com.mypackage/com.mypackage.MyActivity
How can I prevent this ?
Later edit: if I am using it without any animation, everything works fine and no error is shown on logcat. So I suppose it has to do something with the animation.
The animation I am using:
<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android"
android:shareInterpolator="false" >
<translate
android:duration="#android:integer/config_mediumAnimTime"
android:fromYDelta="0%p"
android:interpolator="#android:anim/accelerate_interpolator"
android:toYDelta="80%p" />
</set>

The only solution that works so far, without throwing an error is this:
#Override
public void onAnimationEnd(Animation animation) {
Handler handler = new Handler();
handler.postDelayed(new Runnable() {
#Override
public void run() {
dismiss();
}
}, 10);
}
I am open to any other sugestions

You have pass fragment context as a getSupportFragmentManager().
So you have to change it:
myDialog.show(getFragmentManager(), "");

I do not see any such issues:
public class MyDIalog extends DialogFragment {
#Override
public Dialog onCreateDialog(Bundle savedInstanceState) {
final Button b = new Button(getActivity());
final Dialog d = super.onCreateDialog(savedInstanceState);
d.setContentView(b);
b.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
b.animate().rotationYBy(180).setDuration(500).setListener(new Animator.AnimatorListener() {
#Override
public void onAnimationStart(Animator animator) {
}
#Override
public void onAnimationEnd(Animator animator) {
dismiss();
}
#Override
public void onAnimationCancel(Animator animator) {
}
#Override
public void onAnimationRepeat(Animator animator) {
}
});
}
});
return d;
}
}
works fine with:
new MyDIalog().show(getFragmentManager(),"dialog");
Any ways, you can schedule the dismiss() call a bit later by using:
#Override
public void onAnimationEnd(Animator animator) {
getActivity().runOnUiThread(new Runnable() {
#Override
public void run() {
dismiss();
}
});
}

You can use like this.
#Override
public void onAnimationEnd(Animation animation) {
Handler handler = new Handler();
handler.post(new Runnable() {
#Override
public void run() {
dismiss();
}
});
}
here, the advantage is, you don't define your own time, this way it may help to keep everything else simple, as a user can surprise you even within a short duration if dialog kept without dismissing after the animation ends.

I am not sure if it's too late to answer your question but the only way to get rid of this error is to post the dialogue removal code in a view's post method in your onAnimationEnd().
for example:
view.post(new Runnable() {
#Override
public void run() {
windowManager.removeView(layout);
}
});
