Showing a AlertDialog in a onItemLongClick is giving a error about the parent what I have to do?

Question

I am trying to show a dialog when the user do onItemLongClick of a Listview for confirm if the user wants do that but give me this error in the line of the adb.show():

The specified child already has a parent. You must call removeView() on the child's parent first

with the folowing code:

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

            AlertDialog.Builder adb = new AlertDialog.Builder(getBaseContext());
            adb.setView(view);
            adb.setTitle("Title of alert dialog");
            adb.setIcon(android.R.drawable.ic_dialog_alert);
            adb.setPositiveButton("OK", new DialogInterface.OnClickListener() {
                public void onClick(DialogInterface dialog, int which) {

                    Toast.makeText(Menu.this, "OK", Toast.LENGTH_LONG).show();
                } });

            adb.setNegativeButton("Cancel", new DialogInterface.OnClickListener() {
                public void onClick(DialogInterface dialog, int which) {
                    Toast.makeText(Menu.this, "cancel", Toast.LENGTH_LONG).show();
                    //finish();
                } });
            adb.show();

            return true;
        }
    });

A very easy mistake, this is missing AlertDialog alertDialog = adb.create(); and there is no need for the setView. You can still create a separate method and instantiate it for every long item click.

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

        createDialog(view);
        return true;
    }
});

Then create a separate method for your dialog:

public void createDialog(View view){

   AlertDialog.Builder adb = new AlertDialog.Builder(this);
    //adb.setView(Main.this);
    adb.setTitle("Title of alert dialog");
    adb.setIcon(android.R.drawable.ic_dialog_alert);
    adb.setPositiveButton("OK", new DialogInterface.OnClickListener() {
        public void onClick(DialogInterface dialog, int which) {

            Toast.makeText(getApplicationContext(), "OK", Toast.LENGTH_LONG).show();
        } });

    adb.setNegativeButton("Cancel", new DialogInterface.OnClickListener() {
        public void onClick(DialogInterface dialog, int which) {
            Toast.makeText(getApplicationContext(), "cancel", Toast.LENGTH_LONG).show();
            //finish();
        } });

    AlertDialog alertDialog = adb.create();
    alertDialog.show();

}
