如何使用 JSoup 进行分页

Question

我正在使用JSoup，我能够在RecyclerView中列出网站的数据。但我想在里面放一页。我按照下面的教程进行操作，但它只显示前几页。有人知道我该怎么做吗？

教程：http://www.yudiz.com/pagination-data-scraping-in-android-using-jsoupjava-html-parser/

private class Description extends AsyncTask<Void, Void, Void> {
String desc;

@Override
protected void onPreExecute() {
super.onPreExecute();
mProgressDialog = new ProgressDialog(MainActivity.this);
mProgressDialog.setTitle("Android Basic JSoup Tutorial");
mProgressDialog.setMessage("Loading...");
mProgressDialog.setIndeterminate(false);
mProgressDialog.show();
}

@Override
protected Void doInBackground(Void... params) {
try {
// Connect to the web site
Document mBlogDocument = Jsoup.connect(url).get();
// Using Elements to get the Meta data
Elements mElementDataSize = mBlogDocument.select("div[class=author-date]");
// Locate the content attribute
int mElementSize = mElementDataSize.size();

for (int i = 0; i < mElementSize; i++) {
Elements mElementAuthorName = mBlogDocument.select("span[class=vcard author post-author test]").select("a").eq(i);
String mAuthorName = mElementAuthorName.text();

Elements mElementBlogUploadDate = mBlogDocument.select("span[class=post-date updated]").eq(i);
String mBlogUploadDate = mElementBlogUploadDate.text();

Elements mElementBlogTitle = mBlogDocument.select("h2[class=entry-title]").select("a").eq(i);
String mBlogTitle = mElementBlogTitle.text();

mAuthorNameList.add(mAuthorName);
mBlogUploadDateList.add(mBlogUploadDate);
mBlogTitleList.add(mBlogTitle);
}
} catch (IOException e) {
e.printStackTrace();
}
return null;
}

@Override
protected void onPostExecute(Void result) {
// Set description into TextView

RecyclerView mRecyclerView = (RecyclerView)findViewById(R.id.act_recyclerview);

DataAdapter mDataAdapter = new DataAdapter(MainActivity.this, mBlogTitleList, mAuthorNameList, mBlogUploadDateList);
RecyclerView.LayoutManager mLayoutManager = new LinearLayoutManager(getApplicationContext());
mRecyclerView.setLayoutManager(mLayoutManager);
mRecyclerView.setAdapter(mDataAdapter);

mProgressDialog.dismiss();
}
}

试试这个

List<String> mBlogTitleList = new ArrayList();  
List<String> mAuthorNameList = new ArrayList();
List<String> mBlogUploadDateList = new ArrayList();
RecyclerView mRecyclerView = (RecyclerView)findViewById(R.id.act_recyclerview);
DataAdapter mDataAdapter = new DataAdapter(MainActivity.this, mBlogTitleList, mAuthorNameList, mBlogUploadDateList);
RecyclerView.LayoutManager mLayoutManager = new LinearLayoutManager(getApplicationContext());
mRecyclerView.setLayoutManager(mLayoutManager);
mRecyclerView.setAdapter(mDataAdapter);
private class Description extends AsyncTask<Void, Void, Void> {
String desc;
List<String> mBlogTitleListDescription = new ArrayList();    
List<String> mAuthorNameListDescription = new ArrayList();   
List<String> mBlogUploadDateListDescription = new ArrayList();   
@Override
protected void onPreExecute() {
super.onPreExecute();
mProgressDialog = new ProgressDialog(MainActivity.this);
mProgressDialog.setTitle("Android Basic JSoup Tutorial");
mProgressDialog.setMessage("Loading...");
mProgressDialog.setIndeterminate(false);
mProgressDialog.show();
}
@Override
protected Void doInBackground(Void... params) {
try {
// Connect to the web site
Document mBlogDocument = Jsoup.connect(url).get();
// Using Elements to get the Meta data
Elements mElementDataSize = mBlogDocument.select("div[class=author-date]");
// Locate the content attribute
int mElementSize = mElementDataSize.size();
for (int i = 0; i < mElementSize; i++) {
Elements mElementAuthorName = mBlogDocument.select("span[class=vcard author post-author test]").select("a").eq(i);
String mAuthorName = mElementAuthorName.text();
Elements mElementBlogUploadDate = mBlogDocument.select("span[class=post-date updated]").eq(i);
String mBlogUploadDate = mElementBlogUploadDate.text();
Elements mElementBlogTitle = mBlogDocument.select("h2[class=entry-title]").select("a").eq(i);
String mBlogTitle = mElementBlogTitle.text();
mAuthorNameListDescription.add(mAuthorName);
mBlogUploadDateListDescription.add(mBlogUploadDate);
mBlogTitleListDescription.add(mBlogTitle);
}
} catch (IOException e) {
e.printStackTrace();
}
return null;
}
@Override
protected void onPostExecute(Void result) {
// Set description into TextView
mBlogTitleList.addAll(mBlogTitleListDescription);
mAuthorNameList.addAll(mAuthorNameListDescription);
mBlogUploadDateList.addAll(mBlogUploadDateListDescription);
mDataAdapter.notifyDataSetChanged();
mProgressDialog.dismiss();
}
}
