android - 为什么 ObjectAnimator setDuration 不起作用？

Question

我正在尝试使用 ObjectAnimator 将 RelativeLayout 移动到 Fragment 内的左侧。

方法setDuration根本不会改变持续时间。

我不是在寻找setStartDelay()方法

位置正在即时更改:

RelativeLayout layoutConfig2 = (RelativeLayout) rootView1.findViewById(R.id.layoutListConfig2);
ObjectAnimator pullLeft = ObjectAnimator.ofFloat(layoutConfig2, "translationX", 0f, -600f);
pullLeft.setDuration(4000); // ?
pullLeft.start();

这是我完整的onCreateView:

@Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
                             Bundle savedInstanceState) {

        View rootView1 = inflater.inflate(R.layout.params_config, container, false);

        ListView listConfiguracoes = (ListView) rootView1.findViewById(R.id.list1_configParameters);
        ListView listMotor = (ListView) rootView1.findViewById(R.id.list_motor1);
        final RelativeLayout layoutConfig1 = (RelativeLayout) rootView1.findViewById(R.id.layoutListConfig);
        final RelativeLayout layoutConfig2 = (RelativeLayout) rootView1.findViewById(R.id.layoutListConfig2);

        menutitles = getResources().getStringArray(R.array.array1_config);
        menuIcons = getResources().obtainTypedArray(R.array.arrow_icons);

        rowItems = new ArrayList<RowItem>();
        for (int i = 0; i < menutitles.length; i++) {
            RowItem items = new RowItem(menutitles[i], menuIcons.getResourceId(
                    i, -1));
            rowItems.add(items);
        }


        adapter = new CustomAdapter(getActivity(), rowItems, 2);
        listConfiguracoes.setAdapter(adapter);
        listMotor.setAdapter(adapter);
        layoutConfig2.setVisibility(View.VISIBLE);


        listConfiguracoes.setOnItemClickListener(new AdapterView.OnItemClickListener() {
            @Override
            public void onItemClick(AdapterView<?> parent, View view, int position, long id) {

                Animation slide1, slide2;
                slide1 = AnimationUtils.loadAnimation(getActivity(), R.anim.move_left_slightly);
                slide2 = AnimationUtils.loadAnimation(getActivity(), R.anim.move_left_fast);


                switch (position) {
                    case 0:

                        layoutConfig1.startAnimation(slide1);

                        ObjectAnimator pullLeft = ObjectAnimator.ofFloat(layoutConfig2, "translationX", 0f, -600f);
                        pullLeft.setDuration(4000); // ?
                        pullLeft.start();

                        break;
                }
            }
        });


        return rootView1;

    }

如何修复它？

我知道这有点晚了，但万一有人遇到这个线程: 尝试开发者选项下的“动画师持续时间比例”。当我的被禁用时，我遇到了这个问题。
