示例1: initIconAnimation
import android.support.animation.SpringAnimation; //导入依赖的package包/类
/**
* 初始化开始动画
*/
private void initIconAnimation() {
int screenH = DensityUtil.getScreenH(this);
SpringForce springForce = new SpringForce()
.setDampingRatio(SpringForce.DAMPING_RATIO_LOW_BOUNCY)
.setStiffness(SpringForce.STIFFNESS_VERY_LOW)
.setFinalPosition(0);
SpringAnimation springAnimation = new SpringAnimation(mCivIcon, DynamicAnimation.TRANSLATION_Y)
.setSpring(springForce)
.setStartValue(screenH);
springAnimation.addEndListener(new DynamicAnimation.OnAnimationEndListener() {
@Override
public void onAnimationEnd(DynamicAnimation animation, boolean canceled, float value, float velocity) {
initTextAnimation();
}
});
springAnimation.start();
}
示例2: animateSettle
import android.support.animation.SpringAnimation; //导入依赖的package包/类
void animateSettle(int targetOffset, float initialVelocity) {
if (settling) return;
if (sheetOffsetHelper.getTopAndBottomOffset() == targetOffset) {
if (targetOffset >= dismissOffset) {
dispatchDismissCallback();
}
return;

settling = true;
final boolean dismissing = targetOffset == dismissOffset;
// if we're dismissing, we don't want the view to decelerate as it reaches the bottom
// so set a target position that actually overshoots a little
final float finalPosition = dismissing ? dismissOffset * 1.1f : targetOffset;
SpringAnimation anim = new SpringAnimation(
sheetOffsetHelper, ViewOffsetHelper.OFFSET_Y, finalPosition)
.setStartValue(sheetOffsetHelper.getTopAndBottomOffset())
