如何使用动画android进行放大和返回？

<set xmlns:android="http://schemas.android.com/apk/res/android">
    <scale
        android:fromXScale="1.0"
        android:toXScale="1.5"
        android:fromYScale="1.0"
        android:toYScale="1.5"
        android:pivotX="50%"
        android:pivotY="50%"
        android:duration="300"
        android:interpolator="@android:anim/accelerate_decelerate_interpolator" />
</set>

View viewToScale = findViewById(R.id.view_to_scale); // 替换为需要放大的视图的ID
Animation scaleAnimation = AnimationUtils.loadAnimation(this, R.anim.scale_up);
viewToScale.startAnimation(scaleAnimation);

<set xmlns:android="http://schemas.android.com/apk/res/android">
    <scale
        android:fromXScale="1.5"
        android:toXScale="1.0"
        android:fromYScale="1.5"
        android:toYScale="1.0"
        android:pivotX="50%"
        android:pivotY="50%"
        android:duration="300"
        android:interpolator="@android:anim/accelerate_decelerate_interpolator" />
</set>

View viewToScale = findViewById(R.id.view_to_scale); // 替换为需要返回的视图的ID
Animation scaleAnimation = AnimationUtils.loadAnimation(this, R.anim.scale_down);
viewToScale.startAnimation(scaleAnimation);
