How to get ListView's textview for intent in ContextMenu?

I have a ListView. This ListView has an array and the array has 5 numbers. First of all, in the first activity the user selects 5 numbers and theses 5 number go in the ListView in the second activity. I want to start an Intent with theses 5 numbers when the user click on any number on the Context menu. The intent will start that position. But why cant I get the selected number?
public class AnaMenu extends AppCompatActivity {
public static final int MENU_Ara = Menu.FIRST+1;
int sayı = 50;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_ana_menu);
ListView liste = (ListView) findViewById(R.id.oyun);
OyunTextView oyunTextView = new OyunTextView();
liste.setAdapter(oyunTextView);
registerForContextMenu(liste);
}
class OyunTextView extends BaseAdapter {
#Override
public int getCount() {
Intent i = getIntent();
final ArrayList<String> secilmis = i.getStringArrayListExtra("listem");
return secilmis.size();
}
#Override
public Object getItem(int position) {
return null;
}
#Override
public long getItemId(int position) {
return 0;
}
#Override
public View getView(int position, View convertView, ViewGroup parent) {
convertView = getLayoutInflater().inflate(R.layout.oyuntextview , null);
TextView namesbox = (TextView)convertView.findViewById(R.id.isim);
TextView sayılar = (TextView)convertView.findViewById(R.id.sayı);
Intent i = getIntent();
final ArrayList<String> secilmis = i.getStringArrayListExtra("listem");
namesbox.setText(secilmis.get(position));
sayılar.setText(String.valueOf(sayı));
if (sayı == 50) {
sayılar.setTextColor(getResources().getColor(R.color.elli));}
return convertView;
}
}
#Override
public void onCreateContextMenu(ContextMenu menu, View v, ContextMenu.ContextMenuInfo menuInfo) {
menu.add(Menu.NONE, MENU_Ara, Menu.NONE, "Ara");
super.onCreateContextMenu(menu, v, menuInfo);
}
#Override
public boolean onContextItemSelected(MenuItem item) {
AdapterView.AdapterContextMenuInfo info = (AdapterView.AdapterContextMenuInfo) item.getMenuInfo();
Intent i = getIntent();
secilmis = i.getStringArrayListExtra("listem");
switch (item.getItemId()) {
case MENU_Ara:
Intent ara = new Intent(Intent.ACTION_DIAL);
ara.setData(Uri.parse());
startActivity(ara);
return true;
}
return super.onContextItemSelected(item);
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
MenuInflater menuInflater = getMenuInflater();
menuInflater.inflate(R.menu.mains,menu);
return super.onCreateOptionsMenu(menu);
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()) {
case R.id.action_browse :ayar();return true;
case R.id.backbut: geri();return true;
}
return super.onOptionsItemSelected(item);
}
private void ayar() {
Intent i = new Intent(AnaMenu.this, Ayarlar.class);
startActivity(i);
}
private void geri() {
Intent ii = new Intent(AnaMenu.this, MainActivity.class);
startActivity(ii);
AnaMenu.this.finish();
}
}
}

You can use arraylistname.get(position) in the onItemClickListener method to get the position of the selected item.

How to Have the item in the listview after clicked

I'm new in Android, I have a listview of items, and I have created a popup menu, when the user press a row he must have an item in a other activity.
my problem is, he sends me always the first item... no matter where I click in the listview.
#Override
protected void onPostExecute(Boolean result) {
super.onPostExecute(result);
if (pDialog.isShowing())
pDialog.dismiss();
final ListAdapter adapter = new SimpleAdapter(busqueda.this, productos,
R.layout.list_layout, new String[]{"codigo", "descrip", "precio", "fisicolug"},
new int[]{R.id.txtCodigo, R.id.txtDescrip, R.id.txtPrecio, R.id.Stock});
lista.setAdapter(adapter);
registerForContextMenu(lista);
registerForContextMenu(textView);
}
}
#Override
public void onCreateContextMenu(ContextMenu menu, View v, ContextMenu.ContextMenuInfo menuInfo) {
MenuInflater inflate = getMenuInflater();
if (v.getId() == R.id.listView) {
inflate.inflate(R.menu.menu_main, menu);
}
}
public boolean onContextItemSelected(final MenuItem item) {
switch (item.getItemId()) {
case R.id.masIn:
TextView textView = (TextView) findViewById(R.id.txtCodigo);
String text = textView.getText().toString();
Intent intent;
intent = new Intent(getApplicationContext(), Resultado.class);
intent.putExtra("CODIGO", text);
startActivity(intent);
super.onContextItemSelected(item);
}
return true;
}

By using listview setOnItemClickListener() you can handle the click event of listview
lista.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
}
});

multiple listview in one activity with contextmenu for each of listview

I have multiple ListView in one activity with ContextMenu for each one of ListView.
Actually it should work fine with all the 7 ListViews,but it work for only Seventh List
this is my code.
ArrayAdapter<Course> adapter;
for(int i=0;i<7;i++){
courses = db.findFiltered(String.format("day == %d ", i), "startTime ASC");
ListView lv1 = (ListView) findViewById (arrayList[i]);
registerForContextMenu(lv1);
lv1.setOnItemClickListener(new OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> arg0, View arg1, int arg2,
long arg3) {
// TODO Auto-generated method stub
}
});
adapter = new CourseListAdapter(this, courses);
lv1.setAdapter(adapter);
}
#Override
public void onCreateContextMenu(android.view.ContextMenu menu, View v, ContextMenuInfo menuInfo)
{
super.onCreateContextMenu(menu, v, menuInfo);
MenuInflater inflater = getMenuInflater();
inflater.inflate(R.menu.contextmenu, menu);
}
#Override
public boolean onContextItemSelected(MenuItem item) {
AdapterContextMenuInfo info = (AdapterContextMenuInfo) item.getMenuInfo();
switch (item.getItemId()) {
case R.id.editItem:
//do something
return true;
case R.id.showItem:
//do something
return true;
case R.id.deleteItem:
db.removeCourse(adapter.getItem(info.position);
adapter.remove(adapter.getItem(info.position));
return true;
default:
return super.onContextItemSelected(item);
}
}
please help

Adapter instance is set to last iteration ListView object. This is quick code change. Try this:
private ArrayAdapter<Course> selectedListViewAdapter;
...
for(int i=0;i<7;i++){
courses = db.findFiltered(String.format("day == %d ", i), "startTime ASC");
ListView lv1 = (ListView) findViewById (arrayList[i]);
registerForContextMenu(lv1);
lv1.setOnItemClickListener(new OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> arg0, View arg1, int arg2,
long arg3) {
// TODO Auto-generated method stub
}
});
ArrayAdapter<Course> adapter = new CourseListAdapter(this, courses);
lv1.setAdapter(adapter);
}
#Override
public void onCreateContextMenu(android.view.ContextMenu menu, View v, ContextMenuInfo menuInfo)
{
super.onCreateContextMenu(menu, v, menuInfo);
MenuInflater inflater = getMenuInflater();
inflater.inflate(R.menu.contextmenu, menu);
try {
ListView selectedListView = (ListView)v;
selectedListViewAdapter = (ArrayAdapter<Course>)selectedListView.getAdapter();
} catch(ClassCastException e) {
}
}
#Override
public boolean onContextItemSelected(MenuItem item) {
AdapterContextMenuInfo info = (AdapterContextMenuInfo) item.getMenuInfo();
switch (item.getItemId()) {
case R.id.editItem:
//do something
return true;
case R.id.showItem:
//do something
return true;
case R.id.deleteItem:
if(null != selectedListViewAdapter) {
db.removeCourse(selectedListViewAdapter.getItem(info.position);
selectedListViewAdapter.remove(selectedListViewAdapter.getItem(info.position));
}
return true;
default:
return super.onContextItemSelected(item);
}
}

Why the contextmenu isn't working?

I have a listview with a custon adapter. I have to put a context menu for it, but it's not working. And I put the onItemLongClick to the list and it's not working too. I don't know how to trigger the contextmenu. If I have to click on an item or long click on it. I do register a long click to get the id from the item.
EDIT I think i figure out whats the problem. I have a button on my item listview. I remove this button from the layout and the context menu worked fine. But I need this button. Why the button was causing problem in the context menu?
This is the class:
public class HistoricoDespesasActivity extends Activity {
Helper h;
AlphaAnimation buttonClick;
DespesasDAO dDAO;
ListView lv;
DespesaHistoricoAdapter adapter;
int idDespesasSelecionada;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_historico_despesas);
lv = (ListView)findViewById(R.id.lvHistoricoDespesas);
TextView tvMarcaModelo = (TextView)findViewById(R.id.tvMarcaModeloCabecalho);
TextView tvApelido = (TextView)findViewById(R.id.tvApelidoCabecalho);
tvApelido.setVisibility(View.INVISIBLE);
tvMarcaModelo.setVisibility(View.INVISIBLE);
buttonClick = new AlphaAnimation(1, 0.5f);
h = new Helper(this);
h.mostraVeiculoAtivo();
adapter = new DespesaHistoricoAdapter(this);
dDAO = new DespesasDAO(this);
dDAO.open();
Cursor cursor = dDAO.consultarTodasDespesasByIdVeiculo(h.getId());
int id;
String data;
String tipoDespesa = null;
double valor;
int tipo = 0;
if(cursor != null && cursor.moveToFirst()){
do {
id = cursor.getInt(cursor.getColumnIndex(DespesasDAO.COLUNA_ID));
data = cursor.getString(cursor.getColumnIndex(DespesasDAO.COLUNA_DESPESA_DATA));
tipo = cursor.getInt(cursor.getColumnIndex(DespesasDAO.COLUNA_ITEM_ID));
valor = cursor.getDouble(cursor.getColumnIndex(DespesasDAO.COLUNA_DESPESA_VALOR));
if(tipo == 1){
tipoDespesa = "Pedágio";
} else if(tipo == 2){
tipoDespesa = "Estacionamento";
} else if(tipo == 3){
tipoDespesa = "Lavagem";
} else if(tipo == 4){
tipoDespesa = "Diversos";
}
adapter.addDespesa(id, tipoDespesa, data, valor);
} while (cursor.moveToNext());
cursor.close();
dDAO.close();
lv.setAdapter(adapter);
}
lv.setLongClickable(true);
lv.setOnItemLongClickListener(new OnItemLongClickListener() {
#Override
public boolean onItemLongClick(AdapterView<?> parent, View view,
int position, long id) {
idDespesasSelecionada = (Integer) parent.getItemAtPosition(position);
return true;
}
});
registerForContextMenu(lv);
}
#Override
public void onCreateContextMenu(ContextMenu menu, View v,
ContextMenuInfo menuInfo) {
super.onCreateContextMenu(menu, v, menuInfo);
menu.setHeaderTitle("Despesas");
menu.add(0, v.getId(), 0, "Deletar");
}
#Override
public boolean onContextItemSelected(MenuItem item) {
if(item.getTitle().equals("Deletar")){
dDAO.open();
dDAO.removerDespesasById(idDespesasSelecionada);
dDAO.close();
}
onCreate(new Bundle());
return super.onContextItemSelected(item);
}
#Override
protected void onResume() {
onCreate(new Bundle());
super.onResume();
}
}

Remove your setOnItemLongClickListener of listView and replace onContextItemSelected with this
#Override
public boolean onContextItemSelected(MenuItem item)
{
AdapterContextMenuInfo info = (AdapterContextMenuInfo) item.getMenuInfo();
if(item.getTitle().equals("Deletar"))
{
dDAO.open();
dDAO.removerDespesasById(info.position);
dDAO.close();
}
return true;
}

change onCreateContextMenu like this :
#Override
public void onCreateContextMenu(ContextMenu menu, View v,ContextMenuInfo menuInfo) {
super.onCreateContextMenu(menu, v, menuInfo);
MenuInflater inflater =getMenuInflater();
inflater.inflate(R.menu.more_tab_menu, menu);
}
see this topic :
Android, How to create Context Menu...
EDIT :
use button. image Button and list view is clickable. if you use Button and set android:focusable="false" android:focusableInTouchMode="false" work fine.
