android - 想要在带有 onClick 监听器和 onLongClickListener 的警报对话框中有一个 ListView

Question

要创建带有 ListView 的警报对话框，我使用了以下代码:

                ArrayList<String> namesAL = dbHandler.getArrayListOFnames();
                final ListAdapter m_Adapter = new ArrayAdapter<String>(fragment_console.this,android.R.layout.simple_expandable_list_item_1, namesAL);


                builderSingle.setAdapter(
                        m_Adapter,
                        new DialogInterface.OnClickListener() {
                            @Override
                            public void onClick(DialogInterface dialog, int which) {                                     
                                destloc = getLocLatLng(which);
                                destlat = destloc.latitude;
                                destlng = destloc.longitude;
                                gotoLocation(destlat, destlng, 14);
                                if (marker != null) {
                                    marker.remove();
                                }
                                if (circle != null){
                                    circle.remove();
                                    circle = null;
                                }

                                MarkerOptions options = new MarkerOptions()
                                        .title("Your destination")
                                        .position(destloc)
                                        .position(destloc)
                                        .icon(BitmapDescriptorFactory.fromResource(R.drawable.dest_marker));

                                marker = map.addMarker(options);
                                onDestinationChanged();
                                dialog.cancel();                                   }
                        });
                builderSingle.show();

但这限制了我只能使用OnClickListener，没有长按监听器的选项。我也需要一个长按监听器，以便用户可以从我提供的列表中删除一个条目(实际上仅由用户创建)。如何做到这一点？

                            String strOS = arrayAdapter.getItem(which);
                            Toast.makeText(getApplicationContext(),
                                    "On click selected " + strOS, Toast.LENGTH_SHORT)

            final AlertDialog alertDialog = alertBuilder.create();
            alertDialog.setOnShowListener(new OnShowListener() {

                            String strOS = arrayAdapter.getItem(position);
                            Toast.makeText(getApplicationContext(),
