In my code json and listview are working properly
But when I use alert dialog to display custom listview app crashes:

LayoutInflater li = LayoutInflater.from(MainActivity.this);
                            View view = li.inflate(R.layout.flist, null);

                            AlertDialog.Builder alertDialogBuilder = new AlertDialog.Builder(MainActivity.this);
                            alertDialogBuilder.setView(view);

ArrayList<Food> list = new ArrayList<Food>();
FoodList adapter = new FoodList(MainActivity.this, (ArrayList<Food>)list);
                            foodlist.setAdapter(adapter);
                            alertDialogBuilder
                                    .setCancelable(false)

                                    .setNegativeButton("Cancel", new DialogInterface.OnClickListener() {
                                        public void onClick(DialogInterface dialog, int id) {
                                            dialog.cancel();
                                        }
                                    });

                            // create alert dialog
                            AlertDialog alertDialog = alertDialogBuilder.create();
                            // show it
                            alertDialog.show();
