void |
setupEndValues() This method tells the object to use appropriate information to extract ending values for the animation. |
void |
setupStartValues() This method tells the object to use appropriate information to extract starting values for the animation. |
void |
start() Starts this animation. |
ImageView iv = (ImageView) findViewById(R.id.iv);
//透明度
AlphaAnimation alphaAnimation = new AlphaAnimation(0, 1.0f);
alphaAnimation.setDuration(3000);
iv.setAnimation(alphaAnimation);
2.RotateAnimation 旋转动画
RotateAnimation rotateAnimation = new RotateAnimation(0, 360, Animation.RELATIVE_TO_SELF, 0.5f, Animation.RELATIVE_TO_SELF, 0.5f);
rotateAnimation.setDuration(3000);
iv.setAnimation(rotateAnimation);
ImageView iv = (ImageView) findViewById(R.id.iv);
//旋转
TranslateAnimation translateAnimation = new TranslateAnimation(0, 0, 0, 500);
translateAnimation.setDuration(3000);
translateAnimation.setFillAfter(true);
iv.setAnimation(translateAnimation);
4.ScaleAnimation 拉伸动画
ImageView iv = (ImageView) findViewById(R.id.iv);
//旋转
ScaleAnimation scaleAnimation = new ScaleAnimation(0, 1.2f, 0, 1.2f);
scaleAnimation.setDuration(3000);
scaleAnimation.setFillAfter(true);
iv.setAnimation(scaleAnimation);
translationX
和translationY
:这些属性控制在何处查看位于作为从中由其布局容器设置其左边和顶部坐标的增量。rotation
,rotationX
和rotationY
:这些属性控制在2D(旋转rotation
绕轴心点属性)和3D。scaleX
和scaleY
:这些属性控制绕其轴心点视图的2D缩放。pivotX
和pivotY
:这些属性控制枢轴点的位置,在其周围旋转和缩放变换发生。默认情况下,枢转点位于所述物体的中心。x
和y
:这些都是简单实用的属性来描述其容器查看的最后位置,左侧和顶部的价值观和translationX和translationY值的总和。alpha
:表示在视图的Alpha透明度。此值是1(不透明)默认情况下,以0代表完全透明值(不可见)。 ObjectAnimator objectAnimator = ObjectAnimator.ofFloat(iv_, "translationX", 100f, 300);
objectAnimator.setDuration(3000);
objectAnimator.start();
PropertyValuesHolder pvhX = PropertyValuesHolder.ofFloat("translationX", 170f, 170f);
PropertyValuesHolder pvhY = PropertyValuesHolder.ofFloat("translationY", 0f, 400f);
PropertyValuesHolder scaleX = PropertyValuesHolder.ofFloat("scaleX", 1, 1.5f);
PropertyValuesHolder scaleY = PropertyValuesHolder.ofFloat("scaleY", 1, 1.5f);
ObjectAnimator objectAnimator = ObjectAnimator.ofPropertyValuesHolder(iv_, pvhX, pvhY, scaleX, scaleY);
objectAnimator.setDuration(3000);
objectAnimator.start();
Keyframe keyframe0 = Keyframe.ofFloat(0f, 100);
Keyframe keyframe1 = Keyframe.ofFloat(.01f, 500);
Keyframe keyframe2 = Keyframe.ofFloat(0f, 400);
Keyframe keyframe3 = Keyframe.ofFloat(1f, 1000);
PropertyValuesHolder pvhM1 = PropertyValuesHolder.ofKeyframe("translationX", keyframe0, keyframe1);
PropertyValuesHolder pvhM2 = PropertyValuesHolder.ofKeyframe("translationY", keyframe2, keyframe3);
ObjectAnimator trans = ObjectAnimator.ofPropertyValuesHolder(iv_, pvhM1, pvhM2);
trans.setDuration(3000);
trans.start();
参数意思:
每个keyframe变量第一个参数执行总时间0%~100%,0表示动画未执行,1代码动画执行完毕
keyframe0代表动画在0%时的位置
keyframe1代表动画在1%时所处的位置
keyframe2代表动画在0%时的位置
keyframe3代表动画在100%时的位置
