将 AnimatorSet 添加到动态创建的 FragmentTransaction

Question

我创建了一个AnimatorSet s1。

我想使用s1 AnimatorSet 而不是R.anim.slide_in_top。

如何告诉transaction 使用s1？

private void showsystemerror(int i){
    dialog.cancel();
    Systemerror frag = new Systemerror();
    Bundle bundle = new Bundle();
    bundle.putInt("type", i);
    frag.setArguments(bundle);
    final AnimatorSet s1 = new AnimatorSet();
    final ObjectAnimator anim = ObjectAnimator.ofInt(frag, "x", 150,0);
    anim.setDuration(500);
    s1.play(anim);

    FragmentTransaction transaction = getFragmentManager().beginTransaction();
    transaction.setCustomAnimations(R.anim.slide_in_top, 0);
    transaction.add(R.id.main, frag);
    transaction.commit();
}

将此代码添加到 onCreate 到您的 Systemerror 类中。请务必将returnFrag 替换为您的返回variable。

    final AnimatorSet s1 = new AnimatorSet();
    final ObjectAnimator anim = ObjectAnimator.ofFloat(returnFrag, "x", 150,0);
    anim.setDuration(500);
    s1.play(anim);
    s1.start();
