Question

我的应用程序在单击按钮时崩溃，日志显示Firebase异常-“发现名称冲突的吸气剂：isChangingConfigurations”

这是课程。

public class tt extends AsyncTask<Void,Void,Void>
{ Member member = new Member();
    DatabaseReference  reff = FirebaseDatabase.getInstance().getReference().child("Member");
    doit ok = new doit();
    @Override
    protected Void doInBackground(Void... voids) {
        member.go();

        ok.setAd_id(member.ad_id);
        ok.setPrice(member.price);
        ok.setUsername(member.username);
        Thread thread = new Thread(new Runnable() {
            @Override
            public void run() {        reff.push().setValue(ok);



            }
        });
        thread.run();
        return null;
    }

这是日志...。

通过使用哈希图解决。...

public class tt extends AsyncTask<Void,Void,Void>
{ Member member = new Member();
    DatabaseReference  reff = FirebaseDatabase.getInstance().getReference().child("Member");
    doit ok = new doit();
    @Override
    protected Void doInBackground(Void... voids) {
        member.go();

        ok.setAd_id(member.ad_id);
        ok.setPrice(member.price);
        ok.setUsername(member.username);
        Thread thread = new Thread(new Runnable() {
            @Override
            public void run() {
                HashMap<String,String>
                        Student = new HashMap<>();
                Student.put("Ad_id",ok.Ad_id);
                Student.put("Price",ok.Price);
                Student.put("Username",ok.Username);
                reff.push().setValue(Student);



            }
        });
        thread.run();
        return null;
    }


}
