Answer 1

You can implement it like this;

this.getListView().setLongClickable(true);
this.getListView().setOnItemLongClickListener(new OnItemLongClickListener() {
    public boolean onItemLongClick(AdapterView<?> parent, View v, int position, long id) {
        AlertDialog.Builder dialogBuilder = new AlertDialog.Builder(ctx);
    dialogBuilder.setTitle("Title");
    dialogBuilder.setMessage("Message?");
    dialogBuilder.setPositiveButton("Edit", new DialogInterface.OnClickListener() {
        @Override
        public void onClick(DialogInterface dialog, int which) {
               //Edit
        }
    });
    dialogBuilder.setNegativeButton("Delete", new DialogInterface.OnClickListener() {
        @Override
        public void onClick(DialogInterface dialog, int which) {
               //Delete
        }
    });
    dialogBuilder.create().show();
        return true;
    }
});

And you can use position as index to access list element.
