Java 如何在RecyclerView中实现setOnScrollListener
当用户访问列表中可见的项目时，如何在底部显示进度条 我已经编写了一段代码，其中我使用web服务获取数据，现在我想填充部分记录，因为我的JSON中有大约630条记录 这是我用来从JSON获取数据并填充到RecyclerView的全部代码 下面是我的JSON的外观，但真正的JSON包含600多条记录：Java 如何在RecyclerView中实现setOnScrollListener,java,android-cardview,android-recyclerview,onscrolllistener,endlessscroll,Java,Android Cardview,Android Recyclerview,Onscrolllistener,Endlessscroll,当用户访问列表中可见的项目时，如何在底部显示进度条 我已经编写了一段代码，其中我使用web服务获取数据，现在我想填充部分记录，因为我的JSON中有大约630条记录 这是我用来从JSON获取数据并填充到RecyclerView的全部代码 下面是我的JSON的外观，但真正的JSON包含600多条记录： http://walldroidhd.com/api.php 有人能指导我在哪里修改代码吗 每当用户使用progressbar滚动到底部时，我想填充更多记录，但我仍然显示所有记录 RecycleS

注意：我个人更喜欢使用RecyclerView onScroll功能来完成我的工作。在onScroll方法中
if (!loading && (totalItemCount - visibleItemCount)
<= (firstVisibleItem + visibleThreshold)) {
// End has been reached
Log.i("...", "end called");
// Do something
new JSONAsyncTask().execute("http://walldroidhd.com/api.php");
loading = true;
}
if（！loading&&（totalItemCount-VisibleTItemCount）
实现更多负载的想法是：
获取一个集合中的所有记录。获取另一个将填充部分记录的集合，例如10条记录。现在，当你到达底部时，填充集合中的下10条记录并通知列表
因此，您的代码如下所示：
ArrayList<NatureItem> tempList; // which holds partial records
tempList = getList(limit, 10);
mAdapter = new RecyclerViewMaterialAdapter(new CardAdapter(getActivity(), tempList), 2);
mRecyclerView.setAdapter(mAdapter);
要显示加载程序/进度，最好使用这是我如何通过OnScrollListener

希望您能有所启发。祝您好运~在xml布局文件中使用recylcerview的活动类
public class WallpaperActivity extends AppCompatActivity implements OnTaskCompleted {
private static final String TAG = "WallpaperActivity";
private Toolbar toolbar;
private RecyclerView mRecyclerView;
private WallPaperDataAdapter mAdapter;
private LinearLayoutManager mLayoutManager;
// to keep track which pages loaded and next pages to load
public static int pageNumber;
private List<WallPaper> wallpaperImagesList;

super.onCreate(savedInstanceState);
setContentView(R.layout.wallpaper_main);
toolbar = (Toolbar) findViewById(R.id.toolbar);
mRecyclerView = (RecyclerView) findViewById(R.id.my_recycler_view);
pageNumber = 1;
wallpaperImagesList = new ArrayList<WallPaper>();
handler = new Handler();
if (toolbar != null) {
setSupportActionBar(toolbar);
getSupportActionBar().setTitle("WallPapers");
}
// use this setting to improve performance if you know that changes
// in content do not change the layout size of the RecyclerView
mRecyclerView.setHasFixedSize(true);
mLayoutManager = new LinearLayoutManager(this);
// use a linear layout manager
mRecyclerView.setLayoutManager(mLayoutManager);
// create an Object for Adapter
mAdapter = new WallPaperDataAdapter(wallpaperImagesList, mRecyclerView);
// set the adapter object to the Recyclerview
mRecyclerView.setAdapter(mAdapter);
getWebServiceData();
mAdapter.setOnLoadMoreListener(new OnLoadMoreListener() {
@Override
public void onLoadMore() {
//add null , so the adapter will check view_type and show progress bar at bottom
wallpaperImagesList.add(null);
mAdapter.notifyItemInserted(wallpaperImagesList.size() - 1);
++pageNumber;
getWebServiceData();
}
});
}
public void getWebServiceData() {
BackGroundTask backGroundTask = new BackGroundTask(this, this, pageNumber);
backGroundTask.execute();
}
@Override
public void onTaskCompleted(String response) {
parsejosnData(response);
}
public void parsejosnData(String response) {
try {
JSONObject jsonObject = new JSONObject(response);
// String json = jsonObject.toString();
JSONArray jsonArray = jsonObject.getJSONArray("wallpapers");
if (jsonArray != null) {
// looping through All albums
if (pageNumber > 1) {
wallpaperImagesList.remove(wallpaperImagesList.size() - 1);
mAdapter.notifyItemRemoved(wallpaperImagesList.size());
}
for (int i = 0; i < jsonArray.length(); i++) {
JSONObject c = jsonArray.getJSONObject(i);
// Storing each json item values in variable
String id = c.getString("id");
String orig_url = c.getString("orig_url");
String thumb_url = c.getString("thumb_url");
String downloads = c.getString("downloads");
String fav = c.getString("fav");
// Creating object for each product
WallPaper singleWall = new WallPaper(id, orig_url, thumb_url, downloads, fav);
// adding HashList to ArrayList
wallpaperImagesList.add(singleWall);
handler.post(new Runnable() {
@Override
public void run() {
mAdapter.notifyItemInserted(wallpaperImagesList.size());
}
});
}
mAdapter.setLoaded();
} else {
Log.d("Wallpapers: ", "null");
}
} catch (JSONException e) {
e.printStackTrace();
}
}
}
用于了解从asynctask加载的web服务数据的接口
public interface OnTaskCompleted{
void onTaskCompleted(String response);
}
请让我知道这是否有效或对您有任何问题。
最好使用Volley或okHttp库进行联网
对于图像加载，我使用了库。另一个示例。在底部设置进度条，并根据滚动/加载和记录更改其可见性。注意：需要调用notifyDataSetChanged（）；方法向适配器添加/刷新数据
recyclerView.setOnScrollListener(new RecyclerView.OnScrollListener() {
@Override
public void onScrolled(RecyclerView recyclerView, int dx, int dy) {
super.onScrolled(recyclerView, dx, dy);
int total = linearLayoutManager.getItemCount();
int firstVisibleItemCount = linearLayoutManager.findFirstVisibleItemPosition();
int lastVisibleItemCount = linearLayoutManager.findLastVisibleItemPosition();
//to avoid multiple calls to loadMore() method
//maintain a boolean value (isLoading). if loadMore() task started set to true and completes set to false
if (!isLoading) {
if (total > 0)
if ((total - 1) == lastVisibleItemCount){
loadMore();//your HTTP stuff goes in this method
loadingProgress.setVisibility(View.VISIBLE);
}else
loadingProgress.setVisibility(View.GONE);
}
}
@Override
public void onScrollStateChanged(RecyclerView recyclerView, int newState) {
super.onScrollStateChanged(recyclerView, newState);
}
});
要在Kotlin中为RecyclerView实现OnScrollListener，可以使用
recyclerViewChat.addOnScrollListener(object : RecyclerView.OnScrollListener() {
override fun onScrollStateChanged(recyclerView: RecyclerView, newState: Int) {
super.onScrollStateChanged(recyclerView, newState)
if (newState == RecyclerView.SCROLL_STATE_IDLE) {
Log.d("scroll", "idle")
} else if (newState == RecyclerView.SCROLL_STATE_SETTLING) {
Log.d("scroll", "settling")
} else if (newState == RecyclerView.SCROLL_STATE_DRAGGING) {
Log.d("scroll", "dragging")
}
}
override fun onScrolled(recyclerView: RecyclerView, dx: Int, dy: Int) {
super.onScrolled(recyclerView, dx, dy)
Log.d("scroll", "scrolling")
}
})
现在被接受的答案是@SilentKnight建议的，因为Android SDK不推荐使用setOnscroll
你应该使用
recyclerview.addOnScrollListener(new RecyclerView.OnScrollListener() {
int ydy = 0;
@Override
public void onScrollStateChanged(@NonNull RecyclerView recyclerView, int newState) {
super.onScrollStateChanged(recyclerView, newState);
}
@Override
public void onScrolled(@NonNull RecyclerView recyclerView, int dx, int dy) {
super.onScrolled(recyclerView, dx, dy);
int offset = dy - ydy;
ydy = dy;
boolean shouldRefresh = (linearLayoutManager.findFirstCompletelyVisibleItemPosition() == 0)
&& (recyclerView.getScrollState() == RecyclerView.SCROLL_STATE_DRAGGING) && offset > 30;
if (shouldRefresh) {
//swipeRefreshLayout.setRefreshing(true);
//Refresh to load data here.
return;
}
boolean shouldPullUpRefresh = linearLayoutManager.findLastCompletelyVisibleItemPosition() == linearLayoutManager.getChildCount() - 1
&& recyclerView.getScrollState() == RecyclerView.SCROLL_STATE_DRAGGING && offset < -30;
if (shouldPullUpRefresh) {
//swipeRefreshLayout.setRefreshing(true);
//refresh to load data here.
return;
}
swipeRefreshLayout.setRefreshing(false);
}
});

和@AtulOHolic我已经实现了recyclerview的onScrollListener（）但不知道如何基于Scroll获取数据这是一个双向过程。首先，您的web服务应提供页面数据。因此，假设您的应用程序加载时调用了第1页。现在，根据上面的github链接实现，您可以看到文本加载更多。这是您需要再次调用web服务的地方，但请询问下一页第2页在哪里这种情况如此类推。获取一个集合中的所有记录。获取另一个集合，该集合将填充部分记录，比如说10条记录。现在，当你到达底部时，填充集合中的下10条记录并通知列表。但是当我滚动RecycelView addonscrolllistener时，这只是为了在之后从web服务加载下一条记录r滚动时到达终点。不要在底部显示进度条。您需要稍微更改适配器类和asynctask以获得此功能。我正面临这样的问题。当在recycler视图中实现搜索并假设只有1项时，将发生额外的api调用。我尝试过面对小问题，p
