found many question on same issue.
How to set OnClickListener on the ImageView after rotation animation
How to write the onclick listener for a view after animation?
i also have same issue, any suggestion ?
You ought to write a fresh, concise question about your specific issue rather than just pointing to other questions. The two questions linked to aren't entirely clear.
I assume your issue is that after applying an animation (such as a TranslateAnimation, for example) to a View, the View no longer responds to touch events in its new position. The reason for this is because the View hasn't been moved to the new position in terms of layout parameters, but rather it has had a transformation applied.
The solution is quite simple: immediately after the animation has completed, actually move the View to the new position. You could set myAnimation.setFillAfter() = false, and set a listener to physically move the View to the target location when the animation has finished:
myAmazingAnimation.setFillAfter() = false;
myAmazingAnimation.setAnimationListener(new Animation.AnimationListener(){
#Override
public void onAnimationEnd(Animation animation) {
// Now actually move the View using LayoutParams
}
#Override
public void onAnimationRepeat(Animation animation) {
}
#Override
public void onAnimationStart(Animation animation) {
}
});
Another variation is to physically move the View at the beginning before animation is applied, and then apply an animation that makes the View start where it used to be and end at 0,0.
I've seen all sorts of code that makes me think that mine should work, but for some reason it does not. I've got an ImageView that animates vertically down another image and I want the mobile imageview to disappear once the animation is complete but it does not. The 'scanbar' imageview is the one in question. it is set as invisible in the XML and is made visible on a button press. I need it to go away when the animation is finished.
public class scan extends Activity {
EditText Quote;
private static final Random rgenerator = new Random();
ImageView scanbar;
public void scanLine() {
// Displays the scanline animation over the wireframe image
ImageView wireframe;
scanbar = (ImageView)findViewById(R.id.scanbar);
wireframe = (ImageView) findViewById(R.id.wireframe);
scanbar.setVisibility(View.VISIBLE);
// Super ultra-secret code
}
Animation.AnimationListener scanListener = new Animation.AnimationListener() {
#Override
public void onAnimationStart(Animation animation) {
// TODO Auto-generated method stub
}
#Override
public void onAnimationRepeat(Animation animation) {
// TODO Auto-generated method stub
}
#Override
public void onAnimationEnd(Animation animation) {
// TODO Auto-generated method stub
scanbar.setVisibility(View.INVISIBLE);
setResults();
}
};
The setResults(); call works properly, so I know that section of code is being executed. Anyone know what I'm doing wrong?
Will give this old question an answer just in case someone stumbles upon it like me.
Check out stickupkid's answer here: Android, setVisbility to gone not working in RelativeLayout. Call clearAnimation() on what ever view is doing the animation before calling View.INVISIBLE
I can confirm that: Calling clearAnimation() on the view that is doing the animation before calling View.INVISIBLE, or GONE does the trick.
It seems that an android animation is not truly finished when the onAnimationEnd event is fired although animation.hasEnded is set to true.
I want my view to change it's background drawable on the end of it's ScaleAnimation which it does, but you can clearly see that it is changed some miliseconds before it finishes. The problem is, that it flickers because the new background appears (=is) scaled for a short time until the animation really finishes.
Is there a way to get either the real end of the animation or just prevent the new background from beeing scaled this short period of time?
Thank you!
//EDIT: I'm using an AnimationListener to get the following call:
#Override
public void onAnimationEnd(Animation animation)
{
View view = (MyView) ((ExtendedScaleAnimation) animation).getView();
view.clearAnimation();
view.requestLayout();
view.refreshBackground(); // <-- this is where the background gets changed
}
Here is the actual bug related to this issue http://code.google.com/p/android-misc-widgets/issues/detail?id=8
This basically states that the onAnimationEnd method doesn't really work well when an AnimationListener is attached to an Animation
The workaround is to listen for the animation events in the view to which you were applying the animation to
For example if initially you were attaching the animation listener to the animation like this
mAnimation.setAnimationListener(new AnimationListener() {
#Override
public void onAnimationEnd(Animation arg0) {
//Functionality here
}
});
and then applying to the animation to a ImageView like this
mImageView.startAnimation(mAnimation);
To work around this issue, you must now create a custom ImageView
public class MyImageView extends ImageView {
and then override the onAnimationEnd method of the View class and provide all the functionality there
#Override
protected void onAnimationEnd() {
super.onAnimationEnd();
//Functionality here
}
This is the proper workaround for this issue, provide the functionality in the over-riden View -> onAnimationEnd method as opposed to the onAnimationEnd method of the AnimationListener attached to the Animation.
This works properly and there is no longer any flicker towards the end of the animation.
I was abe to resolve this by calling clearAnimation() on the view being animated inside onAnimationEnd, that took away the flicker
Its weird why would anyone have to do that, as onAnimationEnd callback should have been called only if the animation has already ended. But I guess the answer lies in the depth of Framework on how view/layout handles animation callback.
For now take it as a hack-free solution, that just works.
animation.setAnimationListener(new AnimationListener() {
public void onAnimationEnd(Animation anim) {
innerView.clearAnimation(); // to get rid of flicker at end of animation
RelativeLayout.LayoutParams lp = new RelativeLayout.LayoutParams
(innerBlockContainer.getWidth(), innerBlockContainer.getHeight());
/* Update lp margin, left/top to update layout after end of Translation */
ViewGroup parent_ofInnerView = (ViewGroup)innerView.getParent();
vp.updateViewLayout(innerBlockContainer, lp);
}
public void onAnimationRepeat(Animation arg0) {}
public void onAnimationStart(Animation arg0) {
}
});
innerView.startAnimation(animation);
I had same issue and solved it using
view.clearAnimation();
before
view.startAnimation(anim);
I had a similar problem and I used Soham's solution with custom view class.
It worked fine, but at the end, I've found a simpler solution that worked for me.
After calling the view.StartAnimation(animation), and before the next step in my program, I've added a short delay that will be long enough to let the animation finish, but short enough to be unnoticeable by the user:
new Handler().postDelayed(new Runnable() {
#Override
public void run() {
nextStepInMyProgram();
}
}, 200);// delay in milliseconds (200)
For some reason the onAnimationStart works properly, and the onAnimationEnd doesnt. So heres how I originally did it and what I changed:
Attempt 1 (flicker):
a) Move image from 0px to 80px
b) In onAnimationEnd, set the image's location to 80px
Attempt 2 (no flicker):
a) In onAnimationStart, set the image's location to 80px
b) Move the image from -80px to 0px
Hope that made sense. Basically I flipped the way I did it
Try to use getAnimation() from your object:
public void onShowListBtnClick(View view)
{
rightPanel.startAnimation(AnimationUtils.loadAnimation(MainActivity.this, R.anim.slide_left));
rightPanel.getAnimation().setAnimationListener(new Animation.AnimationListener() {
#Override
public void onAnimationStart(Animation animation) {
// TODO Auto-generated method stub
}
#Override
public void onAnimationRepeat(Animation animation) {
// TODO Auto-generated method stub
}
#Override
public void onAnimationEnd(Animation animation) {
// write your code here
}
});
}
An easy fix is to add one line to AnimationListener.onAnimationEnd():
#Override
public void onAnimationEnd(Animation a) {
a.setAnimationListener(null);
…
}
annimation can be also stopped on screen rotation. in this case onAnimationEnd() is not being called. my workaround:
animation.setDuration(animationDuration);
animation.setAnimationListener(new AnimationListenerAdapter() {...});
view.startAnimation(animation);
handler.postDelayed(new Runnable() {
#Override
public void run() {
if(!animation.hasEnded()) {
// here you can handle this case
}
}
}, animationDuration + 100);
I had this issue because my Animation was not started in the main thread.
This resulted in a duration of 0.
However , the Animation did play correctly - it just called onAnimationEnd() immediately after execution.
If you are using repeat count as infinite, then onAnimationEnd would not get called. Check the documentation link
You can also use setUpdateListener, then check the current fraction of the animation progress and act accordingly.
Here's a Kotlin example for a fade-out animation which eventually makes the view gone from the layout:
view.animate()
.alpha(0f)
.setDuration(duration)
.setUpdateListener { animation ->
if (animation.animatedFraction > 0.99f) {
view.visibility = View.GONE
}
}
.start()
This worked for me:
#Override
public void onAnimationUpdate(ValueAnimator animation) {
if (Float.compare(animation.getAnimatedFraction(),1.0f)) {
// animation ended;
//do stuff post animation
}
}
I have 2 ImageViews that I translate from the top of the screen to the bottom. these views are infalted from xml and the animation is added from java code. The animation works perfectly, but the onClickListener I added in java code doesn't seem to work. I used fillAfter attribute of the animation to make the iamges stay at their arrival after the translation, but THESE images aren't clickable anymore... However, their position before translation remains clickable...
I can't see the logic of this. Could anyone give me some piece of advice about that?
This is because Animations affects only the drawing of widget. However, The real Location is not affected -It is still in the previous one-.
To overcome this problem, you need to update the layout parameters of the ImageView manually by installing an animation listener as follows:
Animation.setAnimationListener(new AnimationListener() {
public void onAnimationStart(Animation arg0) {
}
public void onAnimationRepeat(Animation arg0) {
//TODO Auto-generated method stub
}
public void onAnimationEnd(Animation arg0) {
android.widget.LinearLayout.LayoutParams params = new LayoutParams(
android.widget.LinearLayout.LayoutParams.FILL_PARENT,
android.widget.LinearLayout.LayoutParams.WRAP_CONTENT);
params.topMargin = addLocationButton.getTop()-100;
ImageView.setLayoutParams(params);
}
});
I have a simple LinearLayout with two Buttons side by side. They are supposed to slide into and out of view from the right side of the screen when needed. I have the animation working and the rest of the work is done, but I have one last problem to solve.
How can I set the LinearLayout's visibility to View.GONE after the slide out animation is complete? I need it to disappear once it's of screen.
Grab a reference of your Animation object doing the animation. Call Animation#setAnimationListener and in the listener's onAnimationEnd method set the visibility to View.GONE.

anim.setAnimationListener(new Animation.AnimationListener(){
#Override
public void onAnimationStart(Animation arg0) {
}
#Override
public void onAnimationRepeat(Animation arg0) {
}
#Override
public void onAnimationEnd(Animation arg0) {
}
});
LinearLayout al = (LinearLayout) findViewById(R.id.layoutid);
al.setVisibility(view.INVISIBLE);
Add the above code in your
onAnimationEnd(){
}
