本文实例为大家分享了Android仿抖音列表效果的具体代码，供大家参考，具体内容如下

当下抖音非常火热，是不是也很心动做一个类似的app吗？

那我们就用RecyclerView实现这个功能吧，关于内存的回收利用就交给RecyclerView就好了。

首先我们先说3个和视频播放暂停相关的接口

public interface OnViewPagerListener {

/**

* 初始化

*/

void onInitComplete(View view);

/**

* 释放

*/

void onPageRelease(boolean isNext,int position,View view);

/**

* 选中

*/

void onPageSelected(int position,boolean isBottom,View view);

}

然后自定义LinearLayoutManager

public class PagerLayoutManager extends LinearLayoutManager {

private PagerSnapHelper mPagerSnapHelper;

private OnViewPagerListener mOnViewPagerListener;

private RecyclerView mRecyclerView;

private int mDrift;//位移，用来判断移动方向

public PagerLayoutManager(Context context,int orientation) {

super(context,orientation,false);

init();

}

public PagerLayoutManager(Context context,int orientation,boolean reverseLayout) {

super(context,reverseLayout);

init();

}

private void init() {

mPagerSnapHelper = new PagerSnapHelper();

}

@Override

public void onAttachedToWindow(RecyclerView view) {

super.onAttachedToWindow(view);

mPagerSnapHelper.attachToRecyclerView(view);

this.mRecyclerView = view;

mRecyclerView.addOnChildAttachStateChangeListener(mChildAttachStateChangeListener);

}

@Override

public void onLayoutChildren(RecyclerView.Recycler recycler,RecyclerView.State state) {

super.onLayoutChildren(recycler,state);

}

/**

* 滑动状态的改变

* 缓慢拖拽-> SCROLL_STATE_DRAGGING

* 快速滚动-> SCROLL_STATE_SETTLING

* 空闲状态-> SCROLL_STATE_IDLE

*

* @param state

*/

@Override

public void onScrollStateChanged(int state) {

switch (state) {

case RecyclerView.SCROLL_STATE_IDLE:

View viewIdle = mPagerSnapHelper.findSnapView(this);

if (viewIdle != null) {

int positionIdle = getPosition(viewIdle);

if (mOnViewPagerListener != null && getChildCount() == 1) {

mOnViewPagerListener.onPageSelected(positionIdle,positionIdle == getItemCount() - 1,viewIdle);

}

}

break;

case RecyclerView.SCROLL_STATE_DRAGGING:

View viewDrag = mPagerSnapHelper.findSnapView(this);

if (viewDrag != null) {

int positionDrag = getPosition(viewDrag);

}

break;

case RecyclerView.SCROLL_STATE_SETTLING:

View viewSettling = mPagerSnapHelper.findSnapView(this);

if (viewSettling != null) {

int positionSettling = getPosition(viewSettling);

}

break;

}

}

/**

* 监听竖直方向的相对偏移量

*

* @param dy

* @param recycler

* @param state

* @return

*/

@Override

public int scrollVerticallyBy(int dy,RecyclerView.Recycler recycler,RecyclerView.State state) {

this.mDrift = dy;

return super.scrollVerticallyBy(dy,recycler,state);

}

/**

* 监听水平方向的相对偏移量

*

* @param dx

* @param recycler

* @param state

* @return

*/

@Override

public int scrollHorizontallyBy(int dx,RecyclerView.State state) {

this.mDrift = dx;

return super.scrollHorizontallyBy(dx,state);

}

/**

* 设置监听

*

* @param listener

*/

public void setOnViewPagerListener(OnViewPagerListener listener) {

this.mOnViewPagerListener = listener;

}

private RecyclerView.OnChildAttachStateChangeListener mChildAttachStateChangeListener = new RecyclerView.OnChildAttachStateChangeListener() {

/**

* itemView依赖Window

*/

@Override

public void onChildViewAttachedToWindow(View view) {

if (mOnViewPagerListener != null && getChildCount() == 1) {

mOnViewPagerListener.onInitComplete(view);

}

}

/**

*itemView脱离Window

*/

@Override

public void onChildViewDetachedFromWindow(View view) {

if (mDrift >= 0) {

if (mOnViewPagerListener != null)

mOnViewPagerListener.onPageRelease(true,getPosition(view),view);

} else {

if (mOnViewPagerListener != null)

mOnViewPagerListener.onPageRelease(false,view);

}

}

};

}

然后大功告成直接使用

recyclerView = findViewById(R.id.recycler_view);

PagerLayoutManager mLayoutManager = new PagerLayoutManager(this,OrientationHelper.VERTICAL);

mDatas.addAll(DataUtils.getDatas());

mAdapter = new VideoAdapter(this,mDatas);

recyclerView.setLayoutManager(mLayoutManager);

recyclerView.setAdapter(mAdapter);

mLayoutManager.setOnViewPagerListener(new OnViewPagerListener() {

@Override

public void onInitComplete(View view) {

playVideo(0,view);

}

@Override

public void onPageSelected(int position,View view) {

playVideo(position,view);

}

@Override

public void onPageRelease(boolean isNext,View view) {

int index = 0;

if (isNext) {

index = 0;

} else {

index = 1;

}

releaseVideo(view);

}

});

/**

* 播放视频

*/

private void playVideo(int position,View view) {

if (view != null) {

mVideoView = view.findViewById(R.id.video_view);

mVideoView.start();

}

}

/**

* 停止播放

*/

private void releaseVideo(View view) {

if (view != null) {

IjkVideoView videoView = view.findViewById(R.id.video_view);

videoView.stopPlayback();

}

}
