я удалил данные с веб-сайта и показал элементы в программе просмотра утилит, и теперь всякий раз, когда новый элемент добавляется в панель утилизации, он должен отображаться как уведомление одновременно, даже если приложение не работает в Android Studio с использованием языка Java
до сих пор я понятия не имел, но это код моего приложения
MainActivity
public class MainActivity extends AppCompatActivity {
private DrawerLayout mydrawer;
private ActionBarDrawerToggle mytoggle;
private ProgressDialog mProgressDialog;
private String url = "MY URL";
ArrayList<String> postTitle = new ArrayList<>();
ArrayList<String> next = new ArrayList<>();
RecyclerView recyclerView;
BottomNavigationView bnv;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
getSupportActionBar().setTitle("NOTIFICATIONS");
getSupportActionBar().setDisplayHomeAsUpEnabled(true);
getSupportActionBar().setDisplayShowHomeEnabled(true);
new Description().execute();
botmview();
draw();
}
private class Description extends AsyncTask<Void, Void, Void> {
@Override
protected void onPreExecute() {
super.onPreExecute();
mProgressDialog = new ProgressDialog(MainActivity.this);
mProgressDialog.setMessage("Loading...");
mProgressDialog.setIndeterminate(false);
mProgressDialog.show();
}
@Override
protected Void doInBackground(Void... params) {
try {
// Connect to the web site
Document document = Jsoup.connect(url).get();
// Using Elements to get the Meta data
Elements links = document.select("table");
Elements docu = links.select("tr");
Elements d = docu.select("a[target]");
// Locate the content attribute
for (Element link : d) {
Elements items = d.select("span");//getting text and urls
// Log.d(String.valueOf(next), "doInBackground: ");//showing urls in logcat
next.add(link.absUrl("href")); //getting and setting urls inside next ArrayList of strings
// postTitle.add(link.text());//setting text to recyclerView items
}
Elements doc = links.select("span");
// Locate the content attribute
for (Element link : doc) {
Elements items = doc.select("span");//getting text and urls

return null;
}
@Override

@Override

return new postViewHolder(itemView);
}
@Override

postViewHolder.tvTitle.setText(postTitle.get(i));
postViewHolder.itemView.setOnClickListener(new View.OnClickListener() {
@Override

if (next.get(i).endsWith(".pdf")) {

я не знаю, что мне делать, потому что я новичок в Android и Java
