我想在Firebase中更改数据时更改“文本视图”中的文本。但是，我想要的结果只是TextView中的更改，但最终还是再次调用了onCreate方法。那么，为了防止在数据更改时调用该方法，应该采取哪些步骤？

我试图在新线程和处理程序中运行它，但结果仍然相同。

@Override
protected void onCreate(Bundle savedInstanceState) {
      super.onCreate(savedInstanceState);
      setContentView(R.layout.activity_chat);
      Log.e("onCreate","oncreate");

      DatabaseReference statusRDB = FirebaseDatabase.getInstance().getReference().child("User").child(friendID).child("CurrentStatus");
        statusRDB.addListenerForSingleValueEvent(new ValueEventListener() {
            @Override
            public void onDataChange(@NonNull Datasnapshot datasnapshot) {
                String status = datasnapshot.child("Status").getvalue().toString();
                String lastactive = datasnapshot.child("Lastactive").getvalue().toString();
                mStatusText.setText(showactive.showactiveTime(status,lastactive));

            }

            @Override
            public void onCancelled(@NonNull DatabaseError databaseError) {

            }
        });

}

这是更改子级后的日志。如我们所见，活动被暂停，然后将再次创建。

预期结果是仅将更改“文本视图”中的文本，而不是调用整个onCreate并启动新活动。
