Here I have created Toast with alertDialog code function, according to below code both function runs in same time and display same time when we clicked listview item. In the below code I have explain how to make toast with AlertDialog function in android.

lvList.setOnItemClickListener(new AdapterView.OnItemClickListener() {
            @Override
            public void onItemClick(AdapterView<?> parent, View view, final int position, long id) {
                ListData mLog = listAdapter.getItem(position);

                Toast.makeText(MainActivity.this, "Title:" + mLog.getTitle() + " Description:" + mLog.getDescription(), Toast.LENGTH_LONG).show();
                Toast.makeText(MainActivity.this, "Title: " + mLog.getTitle() + "  Description: " + mLog.getDescription(), Toast.LENGTH_LONG).show();
                AlertDialog alertDialog = new AlertDialog.Builder(MainActivity.this).create();
                alertDialog.setTitle("Remove this Item ?");
                alertDialog.setMessage("Are you sure you want to remove this ListItem? ");
                alertDialog.setButton("OK", new DialogInterface.OnClickListener() {
                    public void onClick(DialogInterface dialog, int which) {
                        Toast.makeText(getApplicationContext(), "You clicked on OK", Toast.LENGTH_SHORT).show();
                    }
                });
                alertDialog.setButton2("Remove", new DialogInterface.OnClickListener() {
                    public void onClick(DialogInterface dialog, int which) {
                        myList.remove(position);
                        listAdapter.notifyDataSetChanged();
                        listAdapter.notifyDataSetChanged();

                        Toast.makeText(getApplicationContext(), "Removed from list", Toast.LENGTH_SHORT).show();
                    }
                });

                alertDialog.show();
            }
        });
