[移动开发]项目功能1：短视频上下滑动

1.重写布局管理类

public class MyLinearManager extends LinearLayoutManager {
  PagerSnapHelper mPagerSnapHelper;
  public MyLinearManager(Context context) {
    super(context);
  }

  public MyLinearManager(Context context, int orientation, boolean reverseLayout) {
    super(context, orientation, reverseLayout);
  }

  public MyLinearManager(Context context, AttributeSet attrs, int defStyleAttr, int defStyleRes) {
    super(context, attrs, defStyleAttr, defStyleRes);
  }

  @Override
  public void onAttachedToWindow(RecyclerView view) {
    super.onAttachedToWindow(view);
    mPagerSnapHelper = new PagerSnapHelper();
    mPagerSnapHelper.attachToRecyclerView(view);
  }
}

2.展示视频的RecycleView

<?xml version="1.0" encoding="utf-8"?>
<androidx.constraintlayout.widget.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context=".mvp.view.fragment.EightFragment">

    <androidx.recyclerview.widget.RecyclerView
        android:id="@+id/rv_eight"
        android:layout_width="match_parent"
        android:layout_height="match_parent"/>

</androidx.constraintlayout.widget.ConstraintLayout>

3.java

//获取控件
//RecycleView
private RecyclerView rvEight;
//视频适配器
private MyVideoAdapter mMyVideoAdapter;
//布局管理类
private MyLinearManager mMyLinearManager;
//视频集合 这里是我自己解的串
private ArrayList<VideoBean.DataBean> mList = new ArrayList<>();

//适配

mMyLinearManager = new MyLinearManager(getActivity());
rvEight.setLayoutManager(mMyLinearManager);
rvEight.setAdapter(mMyVideoAdapter);

绑定视频item

??

整个项目由MVP完成?
