android - 如何为 RecyclerView 项目入口设置动画(滑入)？

Question

基本上我想要类似 this (at the 30 second mark) 的东西

我希望我的项目在 Activity 开始后按顺序滑入。

我试过谷歌搜索。我找不到任何我能理解的东西。我仍然在为 Android 开发应用程序这个疯狂的世界中找到自己的方式。

谢谢。

像这样在recyclerView上添加动画

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);
