creating a menu after a long click event on a list view

Question

I have a list view connected to a database, showing a all the entries. I want a menu to show up if the user long clicks a item in the listview(database entry), showing optio

Answer 1

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.

Answer 2

A quick note for those still struggling, there're two methods

registerForContextMenu(list);
unregisterForContextMenu(list);

Make sure you pick the first.

Answer 3

Use registerForContextMenu(); to link context menu to any View successor.

To access to selected ListItem data, simple use the AdapterView.AdapterContextMenuInfo. E.g.:

@Override
public boolean onContextItemSelected(MenuItem item) {
    AdapterView.AdapterContextMenuInfo menuinfo = (AdapterView.AdapterContextMenuInfo)item.getMenuInfo();
    long selectid = menuinfo.id; //_id from database in this case
    int selectpos = menuinfo.position; //position in the adapter
    switch (item.getItemId()) {
    case 1:
        doSomething(selectid);
    break;
    case 2:
        doSomethingElse(selectpos);
    }
    return super.onContextItemSelected(item);
}

Answer 4

**

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;
    }

Answer 5

You can call Activity.openOptionsMenu() in your click item method

Answer 6

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;
          }
        });
