Example 11 with PathInterpolator

use of android.view.animation.PathInterpolator in project android_frameworks_base by DirtyUnicorns.

the class FlingAnimationUtils method getDismissingProperties.

private AnimatorProperties getDismissingProperties(float currValue, float endValue, float velocity, float maxDistance) {
    float maxLengthSeconds = (float) (mMaxLengthSeconds * Math.pow(Math.abs(endValue - currValue) / maxDistance, 0.5f));
    float diff = Math.abs(endValue - currValue);
    float velAbs = Math.abs(velocity);
    float y2 = calculateLinearOutFasterInY2(velAbs);
    float startGradient = y2 / LINEAR_OUT_FASTER_IN_X2;
    Interpolator mLinearOutFasterIn = new PathInterpolator(0, 0, LINEAR_OUT_FASTER_IN_X2, y2);
    float durationSeconds = startGradient * diff / velAbs;
    if (durationSeconds <= maxLengthSeconds) {
        mAnimatorProperties.interpolator = mLinearOutFasterIn;
    } else if (velAbs >= mMinVelocityPxPerSecond) {
        // Cross fade between linear-out-faster-in and linear interpolator with current
        // velocity.
        durationSeconds = maxLengthSeconds;
        VelocityInterpolator velocityInterpolator = new VelocityInterpolator(durationSeconds, velAbs, diff);
        InterpolatorInterpolator superInterpolator = new InterpolatorInterpolator(velocityInterpolator, mLinearOutFasterIn, mLinearOutSlowIn);
        mAnimatorProperties.interpolator = superInterpolator;
    } else {
        // Just use a normal interpolator which doesn't take the velocity into account.
        durationSeconds = maxLengthSeconds;
        mAnimatorProperties.interpolator = Interpolators.FAST_OUT_LINEAR_IN;
    }
    mAnimatorProperties.duration = (long) (durationSeconds * 1000);

Example 12 with PathInterpolator

use of android.view.animation.PathInterpolator in project Android-Material-Examples by saulmm.

the class GUIUtils method configureWindowEnterExitExplodeTransition.

    Fade ex = new Fade();
    ex.setInterpolator(new PathInterpolator(0.4f, 0, 1, 1));
    ex.setDuration(5000);
