Android:如何动画viewstub？

<ViewStub
    android:id="@+id/view_stub"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:inflatedId="@+id/view_stub_inflated"
    android:layout="@layout/view_stub_layout" />

<set xmlns:android="http://schemas.android.com/apk/res/android"
    android:shareInterpolator="false">
   <alpha
        android:duration="1000"
        android:fromAlpha="0.0"
        android:toAlpha="1.0"
        android:repeatCount="0" />
   <scale
        android:duration="1000"
        android:fromXScale="1.0"
        android:toXScale="1.2"
        android:fromYScale="1.0"
        android:toYScale="1.2"
        android:pivotX="50%"
        android:pivotY="50%"
        android:repeatCount="0" />
</set>

ViewStub viewStub = findViewById(R.id.view_stub);
viewStub.setOnInflateListener(new ViewStub.OnInflateListener() {
    @Override
    public void onInflate(ViewStub stub, View inflated) {
        Animation animation = AnimationUtils.loadAnimation(getApplicationContext(), R.anim.view_stub_animation);
        inflated.startAnimation(animation);
    }
});
