ListView displays data twice

I am working on a small application to save the data of the book (such as the name of the book, the type of the book, the author of the book and the year of publication) in a database, but when the data is returned from the databases using CursorLoader It's shown twice in ListView
This is a code of AddBook activity.

Get single JSON value from response Retrofit

Im trying to get a single value from JSON using Retrofit, i followed a tutorial but i got an error saying that "Class anonymous class derived from Callback must be either declared ...." .
what im specifically trying to achieve is to echo a single json property value in a empty string like String Axe = ""; and i fill it with a specific value from the json file from the server. here is what i tried.
Json format
"axe1": {"test1"}

So, i want the value of Json axe1 which is test1 to be parsed and put in into the empty string

You are using wrong import:
import com.android.volley.Response;
Replace it with
import retrofit2.Response;

Firstly, your JSON format is invalid, it should be {"axe1": "test1"}.
To store it you could do :
JSONObject json = new JSONObject(response.body().toString());
Log.i(LOG_TAG, json.getString("axe1"));

I tried to print what i send from Activity Main to Activity ManagePage by Toast, it display exactly what i want to send.
But i dont know why this error display.
Can you help me?
Sorry about my English

You call setBtnCancelNote() method in the onCreate() method of your InsertNote activity. so as soon as InsertNote starts it tries to launch the ManagePage activity.
The problem is your ManagePage activity expects the value IdUser in the bundle received from the intent. But you do not pass this value to ManagePage activity when you start it from InsertNote activity.
You probably want to add this line to your setBtncancelNote() method in InsertPage activity -
newIntent.putExtra("IdUser", //The Values here);
If you pass this value then ManageNote will not crash.

please add more info like line numbers, otherwise its difficult to debug it remotely ..
Anyway, my guess is you have to check for null pointers when you do stuff like getIntent().getExtras()
just put some breakpoints there, and step by step and you'll figure it out

How I can remove items of ListView?

The apk is a memo pad or something like that. First you can put the title and then the note and if you press the button "Save" the note is saved and it saves in database. And if you press the button "Notes", you can view a list with all notes saved in database and you can select all notes and in the top of screen, you can read how many notes are selected. Ok, it's fine but I need remove notes when the are selected and I press the button with bin icon in the top menu.
The code:
package com.example.u2tarea3;
import android.content.Context;
import android.database.sqlite.SQLiteDatabase;
import android.database.sqlite.SQLiteOpenHelper;
public class AnotacionesOpenHelperSingleton extends SQLiteOpenHelper {
private static AnotacionesOpenHelperSingleton instancia = null;

You'll need to remove the note from the database and the ListView, and then call ListViewAdapter.notifyDataSetChanged()
To delete from the datasource have a method in the class that deals with the datasource:
/**
* Delete a note given an id.
* #param id Key used to identify a note to delete.
*/
public void deleteNote(long id) {
System.out.println("Note deleted with id: " + id);
database.delete(ListOpenHelper.TABLE_MEMOS,
ListOpenHelper.ID + " = " + id,
null);
}
To refresh the ListView you could simply clear and re-add all the Views via the ListViewAdapter:
// Refresh adapter view with new data
ListAdapter.clear();
ListAdapter.addAll(dataSource.getAllNotes());
ListAdapter.notifyDataSetChanged();
Alternatively remove only a single element from the ListViewAdapter and call notifyDataSetChanged();.

Thank for your help

change your method like below.you need to call super.onCreateOptionsMenu like below
#Override
public void onCreateOptionsMenu(Menu menu, MenuInflater inflater) {
super.onCreateOptionsMenu(menu, inflater);
inflater.inflate(R.menu.menu_send_card, menu);
}
and set setHasOptionsMenu(true); in your oncreateview befor return v;
