Fling animation is an animation that continues an initial momentum (most often from gesture velocity) and gradually slows down. The fling animation will come to a stop when the velocity of the animation is below the threshold derived from setMinimumVisibleChange(float)
, or when the value of the animation has gone beyond the min or max value defined via DynamicAnimation#setMinValue(float)
or DynamicAnimation#setMaxValue(float)
. It is recommended to restrict the fling animation with min and/or max value, such that the animation can end when it goes beyond screen bounds, thus preserving CPU cycles and resources.
For example, you can create a fling animation that animates the translationX of a view:
FlingAnimation flingAnim = new FlingAnimation(view, DynamicAnimation.TRANSLATION_X) // Sets the start velocity to -2000 (pixel/s) .setStartVelocity(-2000) // Optional but recommended to set a reasonable min and max range for the animation. // In this particular case, we set the min and max to -200 and 2000 respectively. .setMinValue(-200).setMaxValue(2000); flingAnim.start();
