Firebase从列表视图中检索特定数据并将其显示在文本视图

Question

我想在列表视图中将用户点击的项目的详细信息显示在文本视图中。但是出于某种原因，无论我单击哪个项目，文本视图将始终只显示数据库中的一个数据。我甚至不确定这是否是正确的方法。请帮我解决这个问题。如果没有足够的信息，请告诉我。

MainActivity：

private void showDetailsDialog(final String teamName){
    AlertDialog.Builder dialogBuilder = new AlertDialog.Builder(this);
    LayoutInflater inflater = getLayoutInflater();
    final View dialogView = inflater.inflate(R.layout.details_dialog, null);
    dialogBuilder.setView(dialogView);

    final TextView textViewDetails = (TextView) dialogView.findViewById(R.id.textViewDetails);

    dialogBuilder.setTitle(teamName);
    final AlertDialog b = dialogBuilder.create();
    b.show();

    databaseTeams.addValueEventListener(new ValueEventListener() {

        @Override
        public void onDataChange(DataSnapshot snapshot) {

            for (DataSnapshot postSnapshot : snapshot.getChildren()) {


                //Getting the data from snapshot
                Team team = postSnapshot.getValue(Team.class);

                //Adding it to a string
                String string =  "Team Name: "+team.getTeamName()+"\nSport: "+team.getTeamSport()+"\nTeam Leader: "+team.getTeamOwner()+
                        "\nDate: "+team.getDate()+"\nTime: "+team.getTime()+"\n\n";

                //Displaying it on textview
                textViewDetails.setText(string);
            }
        }

        @Override
        public void onCancelled(DatabaseError databaseError) {

        }

    });

}

数据库：

它将始终显示＆＃34; ping＆＃34;细节无论我点击哪一个。
