我有这个动画:
<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android"
android:interpolator="@android:anim/decelerate_interpolator">
<scale android:fromXScale="1.0" android:toXScale="2.0"
android:fromYScale="1.0" android:toYScale="2.0"
android:pivotX="50%p" android:pivotY="50%p"
android:duration="2000" />
</set>
但我必须在我的代码中使其动态:
AnimationSet animSet = new AnimationSet(false);
animSet.setInterpolator(AnimationUtils.loadInterpolator(AddPhoto.this,
android.R.anim.decelerate_interpolator));
ScaleAnimation zoom = new ScaleAnimation(1.0f, 1.0f, 2.0f, 2.0f);
zoom.setDuration(2000);
animSet.addAnimation(zoom);
但是不一样,我做错了什么?谢谢。
最佳答案
您忘记设置 PivotX 和 PivotY。使用以下 ScaleAnimator 构造函数
public ScaleAnimation (float fromX, float toX, float fromY, float toY,
float pivotX, float pivotY)
Parameters
fromX Horizontal scaling factor to apply at the start of the animation
toX Horizontal scaling factor to apply at the end of the animation
fromY Vertical scaling factor to apply at the start of the animation
toY Vertical scaling factor to apply at the end of the animation
pivotX The X coordinate of the point about which the object is being scaled,
specified as an absolute number where 0 is the left edge. (This point
remains fixed while the object changes size.)
pivotY The Y coordinate of the point about which the object is being scaled,
specified as an absolute number where 0 is the top edge. (This point
remains fixed while the object changes size.)
