I am using AsyncTask for showing the Arraylist items in Listview. But AsyncTask shows all Arraylist items in a single Listview item. can anybody suggest what's wrong here?
The code:
package com.example.ganesh.async;
import android.os.AsyncTask;
import android.os.Bundle;
import android.support.design.widget.FloatingActionButton;
import android.support.design.widget.Snackbar;
import android.support.v7.app.AppCompatActivity;
import android.support.v7.widget.Toolbar;
import android.view.View;
import android.view.Menu;
import android.view.MenuItem;
import android.widget.ArrayAdapter;
import android.widget.ListView;
import android.widget.ProgressBar;
import android.widget.Toast;
import java.util.ArrayList;
public class MainActivity extends AppCompatActivity {
ProgressBar pb;
ListView l;
String s[] = {"MUMBAI, PUNE, DELHI, BANGLORE, KOLKATA, MUMBAI, PUNE, DELHI, BANGLORE, KOLKATA"};
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
l = (ListView) findViewById(R.id.listview);
pb = (ProgressBar) findViewById(R.id.progressbar);
l.setAdapter(new ArrayAdapter<String>(MainActivity.this, android.R.layout.simple_list_item_1, new ArrayList<String>()));
new myTask().execute();
}
class myTask extends AsyncTask{
ArrayAdapter<String> aa;
int counter = 0;
#Override
protected void onPreExecute() {
aa = (ArrayAdapter<String>) l.getAdapter();
}
#Override
protected Void doInBackground(Object[] params) {
for(int k=0; k<s.length; k++)
{
String po = s[k];
publishProgress(po);
}
return null;
}
protected void onProgressUpdate(Object[] values) {
aa.add(values[0].toString());
counter++;
pb.setProgress(((counter/s.length)*10));
Toast.makeText(MainActivity.this," Added "+values[0],Toast.LENGTH_SHORT).show();
}
#Override
protected void onPostExecute(Object o) {
}
}
}
Output:
Because, the size of your string array is one.
Change this to....
String s[] = {"MUMBAI, PUNE, DELHI, BANGLORE, KOLKATA, MUMBAI, PUNE, DELHI, BANGLORE, KOLKATA"};
this
String s[] = {"MUMBAI", "PUNE", "DELHI", "BANGLORE", "KOLKATA", "MUMBAI", "PUNE", "DELHI", "BANGLORE", "KOLKATA"};

Problem:After the ActionEvent is triggered (selecting an account), the comboBox is null. When I run the program, I can see that the ComboBox is populated. I think I'm doing something wrong with the FXML loader. I read through the following document: https://openjfx.io/javadoc/12/javafx.fxml/javafx/fxml/doc-files/introduction_to_fxml.html#controllers
While thrilling (actually learned a lot), the document did not give me an answer to my problem. Please advise.... Referring me to another source for further education would be appreciated. If you need more information to answer the question, let me know.

After some research, it seems like each FXML document needs it's own controller. Been doing this for about 2 weeks. Excuse the lack of education on my part.
when i filter recyclerview it shows Not found .My Searchview not working.when i run the code its result in Not Found i think there is problem in onQueryTextChange
myfilter function also did not work
#Override
public boolean onQueryTextSubmit(String query) {
Toast.makeText(SecondActivity1.this, "Name is : " + query, Toast.LENGTH_SHORT).show();
return false;
}
#Override
public boolean onQueryTextChange(String newText) {
final List<DatabaseModel> filteredModelList = filter(dbList, newText);
if (filteredModelList.size() > 0) {
// Toast.makeText(SecondActivity1.this, "Found", Toast.LENGTH_SHORT).show();
recyclerAdapter.setFilter(filteredModelList);
return true;
} else {
Toast.makeText(SecondActivity1.this, "Not Found", Toast.LENGTH_SHORT).show();
return false;
}
private List filter(List models, String query) {
query = query.toLowerCase();
recyclerAdapter.notifyDataSetChanged();
final List<DatabaseModel> filteredModelList = new ArrayList<>();
// mRecyclerView.setLayoutManager(new LinearLayoutManager(SecondActivity1.this));
// mRecyclerView.setAdapter(RecyclerAdapter);
for (DatabaseModel model : models) {
final String text = model.getName().toLowerCase();
if (text.contains(query)) {
filteredModelList.add(model);
}
}
return filteredModelList;
//
}
here is filter method which recieve parameter(dblist,newtext) filter method recieves these method when i use toast its show that it takes newText But didnot filter this.i checked many sites but this is same in many sites points.when i enter name toast shows name which i enter but it did not filter

this is my recyclerAdapterCode.i also used Recycleradapter.setFilter(filterModeList) method but it did not work for me.i think in my set filter method error which i did not solve yet.
. But when I clear the search widget I don't get the full list instead I get the empty RecyclerView.
I have the following code which works great when I have standard row selection (always single, never multi).
//This is needed to set the X & Y coordinates of the stage for edit.
myTable.setRowFactory(tableView -> {
TableRow<MyDTO> row = new TableRow<MyDTO>();
row.selectedProperty().addListener((obs, wasSelected, isNowSelected) -> {
if (isNowSelected) {
lastSelectedRow.set(row);
}
});
return row ;
});
I am using the row to get the bounds in parent so that when a user selects to edit that row, I can pop a modal window up under the row for them to edit this.
However, my table is also editable for the common fields where there is no look up needed, etc. In that case I want to edit in the table. All this is working, however to make it more user friendly, I want to have cell selection turned on, but when I do that, the row.selectedProptery() listener doesn't fire.
How can I accomplish that, without trying to listen to the selectedProperty() of each cell?
Thanks
I don't think there's a way to do this without registering a listener with the selection property of each cell, via a cell factory on each table column.
However, this isn't too difficult, and can be done both generically (i.e. with the same code no matter the type of the table column) and also respecting any other cell factory behavior you need. Here is a SSCCE:

I am having problem in populating data from a table in one screen to a Text Field in the other screen. I have two classes FirstClass containing a textbox and a button. On pressing a button a second window is opened containing a Table of values. As the user double clicks a row the value of the second column of the row should be inserted into the textbox of the FirstClass. Code of both the classes is attached. Thanking you in anticipation.

The quick and easy way (but it introduces coupling between the 2 classes) would be to pass userNameFld to your showDialog method and make it a member of TableClass. You can then change its value from the TableClass class.
A better way would be to bind the value of userNameFld to value.
