¿Cómo se puede utilizar ViewPropertyAnimator para establecer Width a un valor específico

Utilice animación simple en lugar de ViewPropertyAnimator

 public class ResizeWidthAnimation extends Animation { private int mWidth; private int mStartWidth; private View mView; public ResizeWidthAnimation(View view, int width) { mView = view; mWidth = width; mStartWidth = view.getWidth(); } @Override protected void applyTransformation(float interpolatedTime, Transformation t) { int newWidth = mStartWidth + (int) ((mWidth - mStartWidth) * interpolatedTime); mView.getLayoutParams().width = newWidth; mView.requestLayout(); } @Override public void initialize(int width, int height, int parentWidth, int parentHeight) { super.initialize(width, height, parentWidth, parentHeight); } @Override public boolean willChangeBounds() { return true; } 

}

Pruebe esto, soporte incluso desde Android 2.3:

  ValueAnimatorCompat exitAnimator = AnimatorCompatHelper.emptyValueAnimator(); exitAnimator.setDuration(TransitCompat.ANIM_DURATION * 4); exitAnimator.addUpdateListener(new AnimatorUpdateListenerCompat() { private float oldWidth = view.getWidth(); private float endWidth = 0; private float oldHeight = view.getHeight(); private float endHeight = 0; private Interpolator interpolator2 = new BakedBezierInterpolator();//Any other will be also OK @Override public void onAnimationUpdate(ValueAnimatorCompat animation) { float fraction = interpolator2.getInterpolation(animation.getAnimatedFraction()); float width = oldWidth + (fraction * (endWidth - oldWidth)); mTarget.get().getLayoutParams().width = (int) width; float height = oldHeight + (fraction * (endHeight - oldHeight)); view.getLayoutParams().height = (int) height; view.requestLayout(); } }); exitAnimator.start();
