creating a menu after a long click event on a list view
First you need to register your context menu on list view.
lv = (ListView) findViewById(R.id.list_view);
registerForContextMenu(lv);
Then, just override activity methods.
/**
* MENU
*/
@Override
public void onCreateContextMenu(ContextMenu menu, View v, ContextMenuInfo menuInfo) {
super.onCreateContextMenu(menu, v, menuInfo);
if (v.getId()==R.id.list_view) {
MenuInflater inflater = getMenuInflater();
inflater.inflate(R.menu.menu_list, menu);
}
}
@Override
public boolean onContextItemSelected(MenuItem item) {
AdapterContextMenuInfo info = (AdapterContextMenuInfo) item.getMenuInfo();
switch(item.getItemId()) {
case R.id.add:
// add stuff here
return true;
case R.id.edit:
// edit stuff here
return true;
case R.id.delete:
// remove stuff here
return true;
default:
return super.onContextItemSelected(item);
}
}
Here is an example of menu_list.xml file (you have to put the file in the res/menu folder).
<?xml version="1.0" encoding="utf-8"?>
<menu
xmlns:android="http://schemas.android.com/apk/res/android">
<item android:id="@+id/add"
android:icon="@android:drawable/ic_menu_add"
android:title="@string/menu_add" />
<item android:id="@+id/edit"
android:icon="@android:drawable/ic_menu_edit"
android:title="@string/menu_edit" />
<item android:id="@+id/delete"
android:icon="@android:drawable/my_icon_delete"
android:title="@string/menu_delete" />
</menu>
Hope it will help.
Instead of using onItemLongClick
you can use
public void onCreateContextMenu(final ContextMenu menu,
final View v, final ContextMenuInfo menuInfo) {
...
}
where you setup the options for edit and delete or whatever you need to.
The actions for the item selected from the context menu can be processed in
public boolean onContextItemSelected(final MenuItem item)
For more information on context menu see here.

Edit The second link is broken as it was quite old. But I guess you can refer one of the other highly voted answer to see all the steps involved,
Another approach:
//Deleted individual cart items
//on list view cell long press
cartItemList.setOnItemLongClickListener (new OnItemLongClickListener() {
@SuppressWarnings("rawtypes")
public boolean onItemLongClick(AdapterView parent, View view, final int position, long id) {
final CharSequence[] items = { "Delete" };
AlertDialog.Builder builder = new AlertDialog.Builder(context);
builder.setTitle("Action:");
builder.setItems(items, new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int item) {
cart = cartList.get(position);
db.removeProductFromCart(context, cart);
new AlertDialog.Builder(context)
.setTitle(getString(R.string.success))
.setMessage(getString(R.string.item_removed))
.setPositiveButton("Done", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int which) {
Intent intent = new Intent(CartDetailsActivity.this, HomeScreen.class);
startActivity(intent);
}
})
.show();
}
});
AlertDialog alert = builder.create();
alert.show();
//do your stuff here
return false;
}
});
You can call Activity.openOptionsMenu()
in your click item method

**
after register your context menu on list view
** override onCreateContextMenu Method like this
@Override
public void onCreateContextMenu(ContextMenu menu,View v, ContextMenu.ContextMenuInfo menuInfo){
if (v.getId() == R.id.listView){
AdapterView.AdapterContextMenuInfo info =(AdapterView.AdapterContextMenuInfo)menuInfo;
MenuItem mnu1=menu.add(0,0,0,"Delete");
MenuItem mnu2=menu.add(0,1,1,"Share");
}
}
then coding for each item that can be selected
@Override
public boolean onContextItemSelected(MenuItem menuItem){
AdapterView.AdapterContextMenuInfo info=(AdapterView.AdapterContextMenuInfo)menuItem.getMenuInfo();
switch (menuItem.getItemId()) {
case 0:
Toast.makeText(this, "Delete Selected", Toast.LENGTH_LONG).show();
break;
case 1:
Toast.makeText(this, "Share Selected", Toast.LENGTH_LONG).show();
break;
default:
break;
}
return true;
}
