如何为RecyclerView的物品入口设置动画(滑入)? [英] How do I animate (slide in) a RecyclerView's item's entrance?

问题描述

基本上我想要类似这(在30秒标记处)的

活动开始后，我希望我的物品按顺序滑入.

I want my items to slide in sequentially once the activity starts.

我尝试了谷歌搜索.我什么也看不懂.在开发适用于Android的应用程序的疯狂世界中，我仍处在前进的道路.

I tried Googling. I found nothing that I can understand. I'm still getting my way around this crazy world of developing apps for Android.

谢谢.

推荐答案

像这样在recyclerView上添加动画

Add animation on recyclerView like this

recyclerView = (RecyclerView) findViewById(R.id.rv);
        recyclerView.setHasFixedSize(true);
        llm = new LinearLayoutManager(getApplicationContext());
        recyclerView.setLayoutManager(llm);

        AnimationSet set = new AnimationSet(true);

        Animation animation = new AlphaAnimation(0.0f, 1.0f);
        animation.setDuration(500);
        set.addAnimation(animation);

        animation = new TranslateAnimation(
                Animation.RELATIVE_TO_SELF, 0.0f, Animation.RELATIVE_TO_SELF, 0.0f,
                Animation.RELATIVE_TO_SELF, -1.0f, Animation.RELATIVE_TO_SELF, 0.0f
        );
        animation.setDuration(100);
        set.addAnimation(animation);

        controller = new LayoutAnimationController(set, 0.5f);

        adapter = new RecycleViewAdapter(poetNameSetGets, this);
        recyclerView.setLayoutAnimation(controller);
