好的，根据您的需求，我可以给出一个大致的实现代码。请注意，这里只是一个大致的代码实现，具体细节需要根据实际情况进行调整。 动态信息的数据模型类： ```java public class Moment { private String avatar; private String nickname; private long publishTime; private String content; private List<String> imageList; private String videoUrl; // getter and setter } ``` RecyclerView的布局样式和item的布局样式： ```xml <!-- RecyclerView布局样式 --> <androidx.recyclerview.widget.RecyclerView android:id="@+id/recycler_view" android:layout_width="match_parent" android:layout_height="match_parent"/> <!-- item布局样式 --> <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="match_parent" android:layout_height="wrap_content"> <ImageView android:id="@+id/avatar" android:layout_width="50dp" android:layout_height="50dp" android:src="@drawable/avatar"/> <TextView android:id="@+id/nickname" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_alignTop="@id/avatar" android:layout_toEndOf="@id/avatar" android:text="nickname"/> <TextView android:id="@+id/publish_time" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_below="@id/nickname" android:text="publishTime"/> <TextView android:id="@+id/content" android:layout_width="match_parent" android:layout_height="wrap_content" android:layout_below="@id/avatar" android:layout_marginTop="10dp" android:text="content"/> <ImageView android:id="@+id/image" android:layout_width="match_parent" android:layout_height="200dp" android:layout_below="@id/content" android:layout_marginTop="10dp" android:scaleType="centerCrop" android:src="@drawable/image"/> <ImageView android:id="@+id/video_cover" android:layout_width="match_parent" android:layout_height="200dp" android:layout_below="@id/content" android:layout_marginTop="10dp" android:scaleType="centerCrop" android:src="@drawable/video_cover"/> <ImageView android:id="@+id/video_play" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_centerInParent="true" android:src="@drawable/video_play"/> </RelativeLayout> ``` RecyclerView Adapter的实现： ```java public class MomentAdapter extends RecyclerView.Adapter<MomentAdapter.MomentViewHolder> { private List<Moment> momentList; public MomentAdapter(List<Moment> momentList) { this.momentList = momentList; } @NonNull @Override public MomentViewHolder onCreateViewHolder(@NonNull ViewGroup parent, int viewType) { View view = LayoutInflater.from(parent.getContext()) .inflate(R.layout.item_moment, parent, false); return new MomentViewHolder(view); } @Override public void onBindViewHolder(@NonNull MomentViewHolder holder, int position) { Moment moment = momentList.get(position); holder.avatar.setImageURI(Uri.parse(moment.getAvatar())); holder.nickname.setText(moment.getNickname()); holder.publishTime.setText(moment.getPublishTime()); holder.content.setText(moment.getContent()); if (moment.getImageList() != null && moment.getImageList().size() > 0) { holder.image.setVisibility(View.VISIBLE); holder.videoCover.setVisibility(View.GONE); holder.videoPlay.setVisibility(View.GONE); Glide.with(holder.itemView.getContext()) .load(moment.getImageList().get(0)) .into(holder.image); } else if (!TextUtils.isEmpty(moment.getVideoUrl())) { holder.image.setVisibility(View.GONE); holder.videoCover.setVisibility(View.VISIBLE); holder.videoPlay.setVisibility(View.VISIBLE); Glide.with(holder.itemView.getContext()) .load(moment.getVideoCover()) .into(holder.videoCover); } else { holder.image.setVisibility(View.GONE); holder.videoCover.setVisibility(View.GONE); holder.videoPlay.setVisibility(View.GONE); } } @Override public int getItemCount() { return momentList.size(); } static class MomentViewHolder extends RecyclerView.ViewHolder { ImageView avatar; TextView nickname; TextView publishTime; TextView content; ImageView image; ImageView videoCover; ImageView videoPlay; MomentViewHolder(@NonNull View itemView) { super(itemView); avatar = itemView.findViewById(R.id.avatar); nickname = itemView.findViewById(R.id.nickname); publishTime = itemView.findViewById(R.id.publish_time); content = itemView.findViewById(R.id.content); image = itemView.findViewById(R.id.image); videoCover = itemView.findViewById(R.id.video_cover); videoPlay = itemView.findViewById(R.id.video_play); } } } ``` 加载数据和显示图片和视频的实现： ```java public class MomentActivity extends AppCompatActivity { private RecyclerView recyclerView; private SwipeRefreshLayout swipeRefreshLayout; private MomentAdapter adapter; private List<Moment> momentList; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_moment); recyclerView = findViewById(R.id.recycler_view); swipeRefreshLayout = findViewById(R.id.swipe_refresh_layout); momentList = new ArrayList<>(); adapter = new MomentAdapter(momentList); recyclerView.setAdapter(adapter); swipeRefreshLayout.setOnRefreshListener(new SwipeRefreshLayout.OnRefreshListener() { @Override public void onRefresh() { // 下拉刷新操作 loadData(); } }); recyclerView.addOnScrollListener(new RecyclerView.OnScrollListener() { @Override public void onScrollStateChanged(@NonNull RecyclerView recyclerView, int newState) { super.onScrollStateChanged(recyclerView, newState); if (!recyclerView.canScrollVertically(1) && newState == RecyclerView.SCROLL_STATE_IDLE) { // 上拉加载更多操作 loadMoreData(); } } }); loadData(); } private void loadData() { // 使用Retrofit和OkHttp等网络请求框架从后台服务器获取数据 // 获取到数据之后，将数据添加到momentList中 // 然后调用adapter.notifyDataSetChanged()更新RecyclerView } private void loadMoreData() { // 使用Retrofit和OkHttp等网络请求框架从后台服务器获取更多数据 // 获取到数据之后，将数据添加到momentList中 // 然后调用adapter.notifyItemRangeInserted()更新RecyclerView } private void displayImage(String url, ImageView imageView) { Glide.with(this) .load(url) .into(imageView); } private void playVideo(String url, ImageView coverView, ImageView playView) { // 使用ExoPlayer等视频播放框架来播放视频 } } ``` 以上是一个大致的代码实现，具体细节需要根据实际情况进行调整。
