Android 4.4.2: Using Listview with combobox inside Fragment

Android 4.4.2: Using Listview with combobox inside Fragment - android

I have a list view inside a fragment like this:
The contacts section shows the user contacts and the groups section shows user groups. both of them are using fragments. I have been able to implement the custom listview for them. Code for contactadaptor used to populate the listview in contact section is given below:
package com.project.iandwe.Adaptor;

import android.view.View;
import android.view.ViewGroup;
import android.widget.*;
import com.project.iandwe.Data.ContactData;
import com.project.iandwe.R;
import java.util.ArrayList;

public class ContactSelectAdaptor extends BaseAdapter implements CompoundButton.OnCheckedChangeListener {
ArrayList<ContactData> listViewRows;
Context context;
public SparseBooleanArray checkboxState;
public ContactSelectAdaptor(Context context){
//Resources resources = context.getResources();
this.context =context;
UserDatabaseAdapter userDatabaseAdapter = new UserDatabaseAdapter(context);

// Log.d("ContactSelectAdaptor"," " + contact_id + " " + first_name + " " + last_name+ " " + email);
if (last_name == null){

}
listViewRows.add(new ContactData(contact_id,first_name,last_name,email,icon));

AS i am new to android, i am not sure if the above code to check for user selection of checkboxes should be done in which section of the fragment? I would actually like to populate this data if the user has selected the Done menu presented on the top right corner but then i am finding it difficult to spend the sparse boolean array from fragment to activity. Is there a way this can be accomplished?
Adding code for the main activity which has the "Done" menu button:
package com.project.iandwe;
import android.content.Intent;
import android.os.Bundle;
import android.support.v4.app.FragmentActivity;
import android.support.v4.app.FragmentManager;
import android.support.v4.view.ViewPager;
import android.view.Menu;
import android.view.MenuInflater;
import android.view.MenuItem;
import android.widget.Toast;
import com.project.iandwe.Adaptor.FragmentContactAdaptor;
import com.project.iandwe.Adaptor.UserDatabaseAdapter;
/**
* Created by NathanDrake on 5/21/2014.
*/
public class AddContacts extends FragmentActivity {
ViewPager viewPager = null;
String name;
String eventId,description,date, time, location;
protected void onCreate( Bundle savedInstanceState){
super.onCreate(savedInstanceState);
setContentView(R.layout.add_contacts);
viewPager = (ViewPager) findViewById(R.id.pager_contacts);
FragmentManager fragmentManager = getSupportFragmentManager();
viewPager.setAdapter(new FragmentContactAdaptor(fragmentManager));
//viewPager.setCurrentItem(1);
Intent intent = getIntent();
eventId = intent.getExtras().getString("eventId");
name = intent.getExtras().getString("name");
description = intent.getExtras().getString("description");
date = intent.getExtras().getString("date");
time = intent.getExtras().getString("time");
location = intent.getExtras().getString("location");
}
public boolean onCreateOptionsMenu(Menu menu){
MenuInflater inflater = getMenuInflater();
inflater.inflate(R.menu.add_event_finish,menu);
return super.onCreateOptionsMenu(menu);
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()) {
case R.id.action_finish:
//UserDatabaseAdapter userDatabaseAdapter = new UserDatabaseAdapter(this);
//long id = userDatabaseAdapter.insertUserEvent(name,description,date,time,location);
//if (id>0 ) {
Toast.makeText(this,"Event successfully Created",Toast.LENGTH_LONG).show();
Intent intent = new Intent(this, HomePage.class);
intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK | Intent.FLAG_ACTIVITY_CLEAR_TASK);
startActivity(intent);
finish();
// }
return true;
default:
return super.onOptionsItemSelected(item);
}
}
}

In the menu done handler try to get your adapter in this way:
ContactsFragments fragment = (ContactsFragments) getSupportFragmentManager()
.findFragmentByTag("ContactsFragments");
ListView listView = fragment.listView;
ContactSelectAdaptor adapter = (ContactSelectAdaptor)listView.getAdaptor();
If you have the adaptor then your sparseb boolean array is visible.

Contact m = DataList.get(position);

companyName.setText(String.valueOf(m.getCompanyName()));
return convertView;
}
}
And here is my main

});
Controller.getInstance(this).addToRequestQueue(jsonreq);
}

}
this code works properly and populates my listview, however, when I click on an item in the listview I have another listview populating that displays all contact items...I just want ONE contact item to display.

I guess your ContactDetail activity is getting the list again. And why do you need to show a listview again if you only need one item upon clicking of one item in your first activity.
Anyway, if you still want to use listview in your ContactDetail then do this..
in your listview.setOnItemClickListener on MainActivity
Intent intent = new Intent(MainActivity.this, ContactDetail.this);
intent.putExtra("contact", l.get(position));
startActivity(intent);
in your ContactDetails activity, replace it with this.. remove that JsonArrayRequest
listView = (ListView) findViewById(R.id.list2);
Contact contact = getIntent().getSerializableExtra("contact");
l.add(contact);
adapter = new ListViewContactAdapter(this, l);
listView.setAdapter(adapter);
and also make sure that your Contact object implements Serializable

Set password visible/invisible in ListVIew with Custom Adapter

Do you have some suggestions for me?

Why my listview not refresh when I press back button and come back to activity?

I'm tired already with my code. I'm writing chat application. My app consist of two activity. First activity has a listview of wich each row contain a last message which was send for the user while a second activity contain the whole conversation. In my app I used socket.io for android. My app works fine. Listview is refresh when a data is receive but when I press back button and then come back to the activity a listview not refresh itself already. In logs console I see that a data has received and "changed" method is called but listview is not refresh. What is wrong in belows code?

#Override

you did not have any callback after you back to this activity .
You can either override onResume() method or startActivityForResult and do something in the onAcitvityForResult method.

Android ListView SearchView

I created an ListView which is filled by SQLite Database.
In my App you can add books to a database and you can view the booklist in the BookDataListActivity
Now I would like to implement a SearchView to filter the books. I used this Video https://www.youtube.com/watch?v=c9yC8XGaSv4&list=PLfBjz1j1UV9kdwpvU1YGsjKoNxOtoKTCs&index=1
But it doesnt work.
Following my code. Hopefully you can help me.
package com.kasutwentyseven.gui4selfshelf.Books;
import android.app.Activity;
import android.database.Cursor;
import android.database.sqlite.SQLiteDatabase;

public class BookDataListActivity extends Activity {
public ListView booklistView;

bookListDataAdapter.getFilter().filter(text);
return false;
}
});
bookDBHelper = new BookDBHelper(getApplicationContext());
sqLiteDatabaseBooks = bookDBHelper.getReadableDatabase();
cursor2 = bookDBHelper.getInformations(sqLiteDatabaseBooks);
if(cursor2.moveToFirst())
{
do{
String booktitle, bookauthor,bookdate, bookrating, bookshelf;
booktitle = cursor2.getString(0);
bookauthor = cursor2.getString(1);
bookdate = cursor2.getString(2);
bookrating = cursor2.getString(3);
bookshelf = cursor2.getString(4);
BookDataProvider bookDataProvider = new BookDataProvider(booktitle, bookauthor, bookdate, bookrating, bookshelf);
bookListDataAdapter.add(bookDataProvider);
}while(cursor2.moveToNext());
}
booklistView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
Toast.makeText(getBaseContext(), parent.getItemAtPosition(position) + " is selected", Toast.LENGTH_LONG).show();

public BookListDataAdapter(Context context,int resource) {
super(context, resource);
}
static class BookLayoutHandler {
TextView BOOKTITLE, BOOKAUTHOR, BOOKDATE, BOOKRATING, BOOKSHELF;
}
#Override
public void add (Object object){
super.add(object);
booklist.add(object);
}
#Override
public int getCount() {
return booklist.size();
}
#Override

return booklist.get(position);
}
#Override

View row1= convertView;
BookLayoutHandler bookLayoutHandler;
if(row1 == null){
LayoutInflater layoutInflater = (LayoutInflater) this.getContext().getSystemService(Context.LAYOUT_INFLATER_SERVICE);
row1 = layoutInflater.inflate(R.layout.row_book_layout, parent, false);
bookLayoutHandler = new BookLayoutHandler();
bookLayoutHandler.BOOKTITLE = (TextView) row1.findViewById(R.id.text_book_title);
bookLayoutHandler.BOOKAUTHOR = (TextView) row1.findViewById(R.id.text_book_author);
bookLayoutHandler.BOOKDATE = (TextView) row1.findViewById(R.id.text_book_date);
bookLayoutHandler.BOOKRATING = (TextView) row1.findViewById(R.id.text_book_rating);
bookLayoutHandler.BOOKSHELF = (TextView) row1.findViewById(R.id.text_book_shelf);
row1.setTag(bookLayoutHandler);
}else{
bookLayoutHandler = (BookLayoutHandler) row1.getTag();
}
BookDataProvider bookDataProvider = (BookDataProvider) this.getItem(position);
bookLayoutHandler.BOOKTITLE.setText(bookDataProvider.getBooktitle());
bookLayoutHandler.BOOKAUTHOR.setText(bookDataProvider.getBookauthor());
bookLayoutHandler.BOOKDATE.setText(bookDataProvider.getBookdate());
bookLayoutHandler.BOOKRATING.setText(bookDataProvider.getBookrating());

Passing the contents of the selected row to another activity

Can anyone advise me on how to pass the values of the selected row in a custom viewList to another activity in android. What i mean is that i have a custom ListView which has 2 textView and a checkbox. When the user checks a checkbox and hits the submit button i want to store the values of the 2 textView fields and pass it along to the next activity. Passing to the activity is not the problem. The problem is i cant figure out how to store the values of the checked row.
The code is pasted below.

Any help will be greatly appreciated.. Thanks!

If you are going to use shared prefs (probably a good idea) - something along these lines might be what you are looking for:
//in caller activity (save shared prefs value) ...
String phone = phoneView.getText().toString();
private SharedPreferences prefs;
prefs = getSharedPreferences("yourPrefName", Context.MODE_PRIVATE);
SharedPreferences.Editor editor = prefs.edit();
editor.putString("phone", phone);
editor.commit();
//in called activity ...
private SharedPreferences prefs;
prefs = getSharedPreferences("yourPrefName", Context.MODE_PRIVATE);
String phone=prefs.getString("phone", null); //will be null if "phone" not found
Hope this helps ...

There's a few different options that Android provides for storing persistent data. They are documented in the following link: http://developer.android.com/guide/topics/data/data-storage.html
You may want to start with a basic SharedPreferences implementation and go from there.
