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

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 options to edit or delete the entry. how can i do this.

Till now, I have tried using a onItemLongClick listener and a toast in it showing the id of the view long clicked.

@Override
public boolean onItemLongClick(AdapterView<?> parent, View view,
		int position, long id) {

	String res = Long.toString(id);
	 Toast toast = Toast.makeText(this, res, Toast.LENGTH_SHORT);
	 toast.show();

	return true;
}

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.

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;
    }

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);
}

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

registerForContextMenu(list);
unregisterForContextMenu(list);

Make sure you pick the first.
