How do I get the ID item in the database?

I am new to android development and must take the value of the id in the clicked item database.
Already searched several posts but not found the answer .
Below is my code Listview :
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.seleciona_jogador_act);
final BancoController bc = new BancoController(this);
final ArrayList<JogadorEntidade> jogadorEntidade = bc.arrayJogador(this);
listView = (ListView) findViewById(R.id.lvSelecionar);
final SelecionaAdapter adapter = new SelecionaAdapter(this, R.layout.adapter_seleciona, jogadorEntidade);
FloatingActionButton fab = (FloatingActionButton) findViewById(R.id.fab);
fab.setBackgroundTintList(ColorStateList.valueOf(background));
fab.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
alertInserirJogador(SelecionaJogadorAct.this);
}
});
listView.setAdapter(adapter);
listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
//I NEED THIS CODE
Context context = getApplicationContext();
CharSequence text = "ID: " + ", Posicao: " + position;
int duration = Toast.LENGTH_SHORT;
Toast.makeText(context, text, duration).show();
//bc.deletaRegistro(id_player);
Intent intent = getIntent();
SelecionaJogadorAct.this.finish();
startActivity(intent);
}
});
}
My Adapter:
public class SelecionaAdapter extends ArrayAdapter<JogadorEntidade> {
Context context;
int layoutID;
ArrayList<JogadorEntidade> alJogador;
public SelecionaAdapter(Context context, int layoutID, ArrayList<JogadorEntidade> alJogador){
super(context, layoutID, alJogador);
this.context = context;
this.alJogador = alJogador;
this.layoutID = layoutID;
}
#Override
public View getView(int position, View convertView, ViewGroup parent){
View row = convertView;
PlayerHolder holder = null;
if (row == null){
LayoutInflater inflater = ((Activity)context).getLayoutInflater();
row = inflater.inflate(layoutID, parent, false);
holder = new PlayerHolder();
holder.txtNome = (TextView)row.findViewById(R.id.txtNomeSelecionar);
holder.txtVitorias = (TextView)row.findViewById(R.id.txtVitóriasSelecionar);
holder.txtDerrotas = (TextView)row.findViewById(R.id.txtDerrotasSelecionar);
row.setTag(holder);
}else {
holder = (PlayerHolder)row.getTag();
}
JogadorEntidade jogadorEntidade = alJogador.get(position);
holder.txtNome.setText(jogadorEntidade.getNome());
holder.txtVitorias.setText("V: " + jogadorEntidade.vitórias);
holder.txtDerrotas.setText("D: " + jogadorEntidade.derrotas);
return row;
}
static class PlayerHolder{
TextView txtNome;
TextView txtVitorias;
TextView txtDerrotas;
}
JogadorEntidade:
public class JogadorEntidade {
public String nome;
public Integer id_jogador;
public String vitórias;
public String derrotas;
public Integer getId_jogador() {
return id_jogador;
}
public void setId_player(int id_player) {
this.id_jogador = id_player;
}
public String getNome() {
return nome;
}
public void setNome(String nome) {
this.nome = nome;
}
public String getVitórias() {
return vitórias;
}
public void setVitórias(String vitórias) {
this.vitórias = vitórias;
}
public String getDerrotas() {
return derrotas;
}
public void setDerrotas(String derrotas) {
this.derrotas = derrotas;
}
public JogadorEntidade(String nome, String vitórias, String derrotas){
super();
this.nome = nome;
this.vitórias = vitórias;
this.derrotas = derrotas;
}
public JogadorEntidade(){}
public void insereJogador(JogadorEntidade jogadorEntidade) {
db = banco.getWritableDatabase();
ContentValues values = new ContentValues();
values.put(banco.NOME_JOGADOR, jogadorEntidade.getNome());
values.put(banco.VITORIAS, jogadorEntidade.getVitórias());
values.put(banco.DERROTAS, jogadorEntidade.getDerrotas());
db.insert(CriaBanco.TABELA_JOGADOR, null, values);
db.close();
}
public Cursor carregaJogador() {
Cursor cursor;
String[] campos = {banco.NOME_JOGADOR, banco.VITORIAS, banco.DERROTAS};
db = banco.getReadableDatabase();
cursor = db.query(banco.TABELA_JOGADOR, campos, null, null, null, null, null, null);
if (cursor != null) {
cursor.moveToFirst();
}
db.close();
return cursor;
}
public void deletaRegistro(int id){
String where = CriaBanco.ID_JOGADOR + "=" + id;
db = banco.getReadableDatabase();
db.delete(CriaBanco.TABELA_JOGADOR, where, null);
db.close();
}
public ArrayList<JogadorEntidade> arrayJogador(Context context) {
ArrayList<JogadorEntidade> al = new ArrayList<JogadorEntidade>();
BancoController bancoController = new BancoController(context);
Cursor cursor;
cursor = bancoController.carregaJogador();
if (cursor != null) {
if (cursor.moveToFirst()) {
String nome = cursor.getString(cursor.getColumnIndex(banco.NOME_JOGADOR));
String vitorias = cursor.getString(cursor.getColumnIndex(banco.VITORIAS));
String derrotas = cursor.getString(cursor.getColumnIndex(banco.DERROTAS));
JogadorEntidade jogadorEntidade = new JogadorEntidade(nome, vitorias, derrotas);
al.add(jogadorEntidade);
while (cursor.moveToNext()) {
nome = cursor.getString(cursor.getColumnIndex(banco.NOME_JOGADOR));
vitorias = cursor.getString(cursor.getColumnIndex(banco.VITORIAS));
derrotas = cursor.getString(cursor.getColumnIndex(banco.DERROTAS));
jogadorEntidade = new JogadorEntidade(nome, vitorias, derrotas);
al.add(jogadorEntidade);
}
}
}
return al;
}

First you need to request the id when making the query (if the id is the one created in the database the column mame is _id or you can use tablename._id or whatever you need):
String[] campos = {"_id", banco.NOME_JOGADOR, banco.VITORIAS, banco.DERROTAS};
Then you need to add the id to the object when you read the cursor:
public ArrayList<JogadorEntidade> arrayJogador(Context context) {
ArrayList<JogadorEntidade> al = new ArrayList<JogadorEntidade>();
BancoController bancoController = new BancoController(context);
Cursor cursor;
cursor = bancoController.carregaJogador();
if (cursor != null) {
if (cursor.moveToFirst()) {
String nome = cursor.getString(cursor.getColumnIndex(banco.NOME_JOGADOR));
String vitorias = cursor.getString(cursor.getColumnIndex(banco.VITORIAS));
String derrotas = cursor.getString(cursor.getColumnIndex(banco.DERROTAS));
long id = cursor.getLong(cursor.getColumnIndex("_id",0));
JogadorEntidade jogadorEntidade = new JogadorEntidade(id, nome, vitorias, derrotas);
al.add(jogadorEntidade);
while (cursor.moveToNext()) {
nome = cursor.getString(cursor.getColumnIndex(banco.NOME_JOGADOR));
vitorias = cursor.getString(cursor.getColumnIndex(banco.VITORIAS));
derrotas = cursor.getString(cursor.getColumnIndex(banco.DERROTAS));
long id = cursor.getLong(cursor.getColumnIndex("_id",0));
jogadorEntidade = new JogadorEntidade(id, nome, vitorias, derrotas);
al.add(jogadorEntidade);
}
}
}
return al;
}
Anyway this is not the way to go in android. You should read all the list and then show it. You should use the viewholder pattern and only load the player when you are going to show it. Also instead of using a list you should move to recyclerviews. Listviews can be consider deprecated at this point. See the tutorial: http://developer.android.com/training/material/lists-cards.html

Can we list notifications we receive for incoming message inside ListView?

I'm developing an app in which the app has to show the receiving messages starts with #. Now i have to show notification for them and i also want to update the notifications in a ListView inside an Activity. Currently i get the messages from inbox using ContentResolver. Because of that once processed messages still shows up in activity. I don't want to show that. I want notifications i receive for the messages starts with # listed in ListView inside an activity.
My Code is
My Activity
public class ActivationActivity extends ActionBarActivity implements OnItemClickListener {
private static ActivationActivity inst;
ArrayList<String> smsMessagesList = new ArrayList<String>();

smsListView.setAdapter(arrayAdapter);
refreshSmsInbox();
smsListView.setOnItemClickListener(this);
}
public void refreshSmsInbox(){
ContentResolver contentResolver=getContentResolver();
final Cursor smsInboxCursor=contentResolver.query(Uri.parse("content://sms/inbox"),null,null,null,null);
int indexBody=smsInboxCursor.getColumnIndex("body");
int indexAddress=smsInboxCursor.getColumnIndex("address");
if (indexBody<0||!smsInboxCursor.moveToFirst()) return;
arrayAdapter.clear();
do {

How to prevent duplicate phone contacts to be added in database?

How to refresh SMS Listview automatically ?

I am creating SMS app. I am sending and receiving SMS with my application and then can show them in ListView. But listview doesn't get updated as soon as I send or receive SMS. I have to press back button , after that if I again go to ListView Activity then new SMS are shown.
How can I make listview refresh automatically as soon as sms arrives or is send ?

you should register a broadcast receiver to get notified upon receiving an SMS and in the onReceive of this receiver you can get new data from cursor and refresh the list view.
To know more about receiver try:
http://androidexample.com/Incomming_SMS_Broadcast_Receiver_-_Android_Example/index.php?view=article_discription&aid=62&aaid=87

You have to use notifydatasetchanged. check out following link.

I am having a doubt that,I have to insert all my calendar events in database and get the current week events by using a query or it can be done without inserting calendar events into database.As a beginner any idea will be usefull for me.

I have already answered for that SO i think it might work just pass two dates.
Code:
Calendar calendar = Calendar.getInstance();
if (Build.VERSION.SDK_INT >= 8) {
l_eventUri = Uri.parse("content://com.android.calendar/events");
} else {
l_eventUri = Uri.parse("content://calendar/events");
}
String dtstart = "dtstart";
String dtend = "dtend";
String[] l_projection = new String[] { "title", "dtstart", "dtend" };
SimpleDateFormat formatter = new SimpleDateFormat("MM/dd/yy");
//StartDate is today 10/28/2013
Date dateCC = formatter.parse("10/28/2013");
calendar.setTime(dateCC);
long after = calendar.getTimeInMillis();
SimpleDateFormat formatterr = new SimpleDateFormat("MM/dd/yy hh:mm:ss");
Calendar endOfDay = Calendar.getInstance();
Date dateCCC = formatterr.parse("11/04/2013 23:59:59");
endOfDay.setTime(dateCCC);
Cursor eventCursorr = cr.query(l_eventUri, new String[] { "title",
"dtstart", "dtend" }, "(" + dtstart + ">" + after + " and "
+ dtend + "<" + endOfDay.getTimeInMillis() + ")", null,
"dtstart ASC");
