How to generate looping animation with ViewPropertyAnimator?

Solution
Well, I am going to answer myself again.
TranslateAnimation class has methods about repeating the animation, so I used it instead of ViewPropertyAnimator.
The following code seems to work:
long duration = 1000* ((long)totalWidth / newsScrollSpeed);
System.out.println("totalWidth="+totalWidth);
TranslateAnimation anim = new TranslateAnimation(0,-totalWidth,0,0);
anim.setInterpolator(linearInterpolator);
anim.setDuration(duration);
anim.setRepeatCount(TranslateAnimation.INFINITE);
anim.setRepeatMode(TranslateAnimation.RESTART);
for(i=0;i<this.getChildCount();i++)
{
View v = this.getChildAt(i);
if(v.getId() == R.id.yuruyen_yazi)
{
continue;
}
v.startAnimation(anim);
}
Problem
I want to build an animation of TextViews, which repeats itself just after completion. For each View I want to animate, I use the following piece of code ``` final float oldX = v.getX(); final float newX = v.getX() - (float)totalWidth; final AnimatorListenerAdapter listener = new AnimatorListenerAdapter() { @Override public void onAnimationEnd(Animator animation) { v.setX(oldX); animFinished = true; //This line won't compile //v.animate().setDuration(animDuration).setInterpolator(newsInterpolator) // .setListener(listener).x(newX); } }; v.animate().setDuration(animDuration).setInterpolator(newsInterpolator) .setListener(listener).x(newX); ``` I tried to place the last piece of code into the onAnimationEnd, but Java will not compile since it considers the object listener as not initialized. Moreover, I don't think that this "recursive" animation invocation is a good solution, it was the first thing which came to my mind. I am suspicious that there is a simple and sound way to implement looping property animation, but I failed to locate it, so I turned here for help. Thanks in advance
