這裏是我的情況,如果用戶在列表視圖中是該團隊的團隊成員,當他長時間點擊團隊時,會出現一個對話框。但是,如果他不是,那麼什麼都不會發生。我設法在用戶創建團隊後顯示對話框,但是當我用同一個帳戶註銷並登錄時,即使我是teamOwner,當我長時間點擊它時,對話框也不會再出現。我將用戶的電子郵件存儲爲teamOwner。我的代碼在下面,讓我知道你是否需要更多的信息。重新登錄後,Firebase對話框將不會出現

MainActivity:

listViewTeams.setOnItemLongClickListener(new AdapterView.OnItemLongClickListener() { 
     FirebaseUser user = firebaseAuth.getCurrentUser(); 
     @Override 
     public boolean onItemLongClick(AdapterView<?> adapterView, View view, int i, long l) { 
      Team team = teams.get(i); 
      String owner = user.getEmail(); 

      if (owner == team.getTeamOwner()) { 
       showUpdateDeleteDialog(team.getTeamId(), team.getTeamName()); 
      } 
      else{ 

      } 
      return true; 
     } 
    }); 

AddActitvity:

private void addTeam() { 
    //getting the values to save 
    String name = editTextName.getText().toString().trim(); 
    String sport = spinnerSport.getSelectedItem().toString(); 
    String date = textDate.getText().toString(); 
    String time = textTime.getText().toString(); 

    FirebaseUser user = firebaseAuth.getCurrentUser(); 
    user.getEmail(); 

    //checking if the value is provided 
    if (!TextUtils.isEmpty(name)) { 

     //getting a unique id using push().getKey() method 
     //it will create a unique id and we will use it as the Primary Key for our Team 
     String id = databaseTeams.push().getKey(); 
     String owner = user.getEmail(); 
     String member = user.getEmail(); 

     //creating an Team Object 
     Team team = new Team(id, name, sport, owner, date, time); 
     Member members = new Member(member); 

     //Saving the Team 
     databaseTeams.child(name).setValue(team); 
     databaseMembers.child(name).setValue(members); 

     //setting edittext to blank again 
     editTextName.setText(""); 

     //displaying a success toast 
     Toast.makeText(this, "Team added", Toast.LENGTH_LONG).show(); 
    } else { 
     //if the value is not given displaying a toast 
     Toast.makeText(this, "Please enter a name", Toast.LENGTH_LONG).show(); 
    } 
} 

Team.java

public class Team { 
private String teamId; 
private String teamName; 
private String teamSport; 
private String teamOwner; 
private String date; 
private String time; 

public Team() { 

} 

public Team(String teamId, String teamName, String teamSport, String teamOwner, String date, String time) { 
    this.teamId = teamId; 
    this.teamName = teamName; 
    this.teamSport = teamSport; 
    this.teamOwner = teamOwner; 
    this.date = date; 
    this.time = time; 
} 

public String getTeamId() {return teamId;} 

public String getTeamName() { 
    return teamName; 
} 

public String getTeamSport() { 
    return teamSport; 
} 

public String getTeamOwner() { return teamOwner; } 

public String getDate(){ return date; } 

public String getTime() { return time; } 

}
