带有长单击侦听器的DialogInterface？

Question

I would like to have a dialog that listens for short and long clicks (when the user holds their finger on an item and react to it by playing a preview of an audio file, without closing the the DialogInterface (sort of providing some convenience to the user).

After checking the API on the DialogInterface class , I see that it only offers an OnClickListener. Is it possible the make the DialogInterface object listen for both ?

Here's the code:

public class SetMetronomeDialogFragment extends DialogFragment {
@Override
public Dialog onCreateDialog(Bundle savedInstanceState) {
    AlertDialog.Builder builder = new AlertDialog.Builder(getActivity());
    builder.setTitle("Pick a tempo");
    builder.setItems(R.array.tempoArray, new DialogInterface.OnClickListener() {

        // this code works fine since it's from the Android Developer site :)
        public void onClick(DialogInterface dialog, int which) {
               // The 'which' argument contains the index position
               // of the selected item
            Toast.makeText(getActivity(), "" + which, Toast.LENGTH_SHORT).show();               
        }

       // this is my 'dream method', doesn't work of course...
       public void onLongClick(DialogInterface dialog, int which) {

           Toast.makeText(getActivity(), "" + which, Toast.LENGTH_SHORT).show();
       }
    });
    return builder.create();
}

}

你可以使用的setView您AlertDialog.Builder ，然后你想要的侦听器添加到您的自定义视图。
