How to make setOnClickListener on a dynamic imageview

Working in Android Studio, I need to add in my app a click listener on my imageview which has a certain animation. This is the code I have in MainActivity:
myImage.startAnimation(myAnimation);
myImage.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
//DO SOMETHING
}
});
myAnimation comes from an XML in anim folder which does a translational animation:
<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android">
<translate
android:interpolator="#android:anim/accelerate_interpolator"
android:repeatCount="infinite"
android:repeatMode="reverse"
android:fromYDelta="0%p"
android:toYDelta="40%p"
android:duration="1000"/>
</set>
This works fine, although this click listener is set on the space that has the image on the layout (activity_main.xml) and does not follow the animation inserted in the image. If I click on the space which belongs to the image in the layout, the click listener starts even if the image is not there due to the animation.
Is there a way in which the click listener is attach to the imageview in motion?
Thank you

This happens because the xml Translate animation you are using, does not really animate the View's property, it just moves the pixels on the screen and so it just looks like it has changed position, that is why the OnClickListener is still active on the View's original position, because Android thinks the View never really moved.
Simple solution use ObjectAnimator or even better ViewPropertyAnimator. Both will animate the View's property and so the OnClicklistener will also change it's position with it.

How to set marquee behaviour in android to alternate programatically

This is the code I am using but the behaviour of the marquee is that is scrolls. How to make it to alternate i.e. it moves from right to left and then left to right.
public void setMarquee(TextView textView) {
textView.setEllipsize(TextUtils.TruncateAt.MARQUEE);
textView.setMarqueeRepeatLimit(-1);
textView.setHorizontallyScrolling(true);
textView.setSelected(true);
textView.requestFocus();
}

Step1
create folder called anim in res directory
step 2
create slide_left.xml
slide_left.xml
<translate
android:duration="3000"
android:fromXDelta="100%"
android:toXDelta="0" />
</set>
step 3
in main_activity.class
LinearLayout mlayout =
(LinearLayout)findViewById(R.id.mlayout); // the view u want to animate
Animation slide_left_anim;
slide_left_anim=
AnimationUtils.loadAnimation(getActivity().getApplicationContext(),
R.anim.slide_left);
slide_left_anim.setRepeatCount(Animation.INFINITE);
mlayout.startAnimation(slide_left_anim);

Best way to implement custom view with animation at the center of the screen?

My GOAL is to implement custom toast in my application as follows:
MyCustomToastClass.makeText(context,View,anyDurationInMS);
I want to set the "Toast" gravity, Layout, duration(not just Length.SHORT/LONG)
Things i've tried so far:
Class with windowManager object
problem was it must implement android system animation in:
params.windowAnimations
and when I tried to implement my custom animation as followed:
windowManager.addView(mLayout);
Animation AlphaAnimation = new ...
it didn't implement my animation.
Class with the rootView element to add the Toast's layout to it:
In this way I succeeded to implement everything only when the root view was FrameLayout type (With other layout I couldn't set the "Toast" gravity to center).
I would appreciate if someone has implemented this feature, Or to guide me if i'm missing something in one of my ways.
thanks

Sorry for misunderstand your question
if you want to create an pop up like toast and the duration is up to you maybe you can try to create a custom view that will contain the content you want to be toasted after that you can place your main layout in the frame layout then everytime the user trigger your custom toast you can add the custom view to your frame layout so it'll be positioned in front of your main layout and for fade in fade out animation you can use this
Animation fadeIn = new AlphaAnimation(0, 1);
fadeIn.setInterpolator(new DecelerateInterpolator()); //add this
fadeIn.setDuration(1000);
Animation fadeOut = new AlphaAnimation(1, 0);
fadeOut.setInterpolator(new AccelerateInterpolator()); //and this
fadeOut.setStartOffset(1000);
fadeOut.setDuration(1000);
or if you want to use XML
FadeIn
<?xml version="1.0" encoding="utf-8"?>
<alpha xmlns:android="http://schemas.android.com/apk/res/android"
android:fromAlpha="0.0"
android:toAlpha= 1.0"
android:duration="1000"
android:repeatCount="infinite"
android:repeatMode="reverse"
/>
FadeOut
<?xml version="1.0" encoding="utf-8"?>
<alpha xmlns:android="http://schemas.android.com/apk/res/android"
android:fromAlpha="1.0"
android:toAlpha="0.0"
android:duration="1000"
android:repeatCount="infinite"
android:repeatMode="reverse"
/>
and for the time you can use
final Handler handler = new Handler();
handler.postDelayed(new Runnable() {
#Override
public void run() {
// FADE OUT THE POP UP/TOAST HERE
}
}, /*SET THE TIME HERE*/);
I hope this answer is clear enough for you
and if you still have some question about my answer don't hesitate to ask in the comment :)

How to avoid blink of View when using animation?

I use translate and rotate animations to position View inside FrameLayout in onCreate event. I want animations to perform instantly so I set duration for both of them to 0. But when application starts there is a short blink of my View in top left corner of screen and then it becomes positioned according to animation parameters. How can I avoid this blink?

I spent whole day with that problem. fillAfter and fillBefore has nothing to do with that. Try this before animation start:
view.setVisibility(View.GONE); // view is our View we trying to animate
Then set animation listener for your animation:
animation.setAnimationListener(new AnimationListener(){
public void onAnimationEnd(Animation animation) {
}
public void onAnimationRepeat(Animation animation) {
}
public void onAnimationStart(Animation animation) {
v.setVisibility(View.VISIBLE);
}

use animation.setFillAfter(true) or animation.setFillBefore(true), depending on your needs. This should resolve the blink

Having a tag inside the parent tag of your animation file will cause this, try it with only one tag and you will see the difference. I am working with this right now

Odaym's answer is the solution for the issue actually. If you have something like that:
<set xmlns:android="http://schemas.android.com/apk/res/android"
android:shareInterpolator="true">
<set
android:duration="1000">
<translate
android:fromXDelta="100%"
android:toXDelta="0"
/>
</set>
</set>
Change it into this:
<set xmlns:android="http://schemas.android.com/apk/res/android"
android:shareInterpolator="true" android:duration="1000">
<translate
android:fromXDelta="100%"
android:toXDelta="0"
/>
</set>

Set the visibility after the animation execution code but not in "onAnimationEnd", also try to set the duration
view.setVisibility(View.VISIBLE); // view is our View we trying to animate

How to stop an image which moves by animation?

I'm trying to move an image from left to right on layout, but not by dragging. I want it to go automatically when something happened. So, i found an animation like this:
<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android"
android:interpolator="#android:anim/accelerate_interpolator" >
<translate
android:duration="1000"
android:fromXDelta="0"
android:toXDelta="200"
android:fillEnabled="true"
android:fillAfter="true" />
</set>
But the problem is i couldn't find how to make it stop there! It's just went back directly. Any suggestion please?
Here is my Java code:
public void onClick(View v) {
runOnRight(this, image);
}
static Animation runOnRight(Activity ctx, View target) {
Animation animation = AnimationUtils.loadAnimation(ctx,
R.anim.slide_left_to_right);
target.startAnimation(animation);
return animation;
}

set FillAfter to true in your animation set xml

When the View.onAnimationEnd() callback is fired, you can set the new View postion with View.layout(int, int, int, int). The View.layout call assign size and position to your view. Refer to the documentation for more information

use the field FillAfter="true" which will stops at the end.
just like following.
