Question

我有这段代码：

FirebaseDatabase database;
EditText taryfaView;
EditText cenaZaMinView;
EditText mnoznikView;
EditText kwotaStartowaView;

DatabaseReference dataRef;
DatabaseReference dataUse;
User user;
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    database = FirebaseDatabase.getInstance();
    dataRef = database.getReference();
    setContentView(R.layout.activity_ustawienia);
    taryfaView = (EditText) findViewById(R.id.editText3);
    cenaZaMinView = (EditText) findViewById(R.id.editText5);
    mnoznikView = (EditText) findViewById(R.id.editText2);
    kwotaStartowaView = (EditText) findViewById(R.id.editText6);

    final Button buttonHaslo = (Button) findViewById(R.id.button2);
    final Button buttonTaryfa = (Button) findViewById(R.id.button11);
    final Button buttonKwota = (Button) findViewById(R.id.button5);
    final Button buttonMnoznik = (Button) findViewById(R.id.button3);
    final Button buttonCena = (Button) findViewById(R.id.button4);

    buttonHaslo.setOnClickListener(new View.OnClickListener() {
        public void onClick(View v) {
            EditText hasloView = (EditText) findViewById(R.id.editText);
            String haslo = hasloView.getText().toString();
            if(!(haslo.equals(null) || haslo.equals(""))){
                dataUse = dataRef.child("UsersLogin").child(Logowanie.id).child("Password");
                dataUse.setValue(haslo);
            }
        }
    });
}

我的调试日志中没有错误，出了什么问题？在EditText中输入文本并单击按钮后，它会更改数据库中的值，确定，然后它返回到上一个活动.. 日志（点击按钮后的每一行）：

请帮忙，我不知道为什么会这样菜单活动代码：

public class Menu extends AppCompatActivity {

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_menu);
}
public void Menu(View view){
    Intent intent = new Intent(this, Ustawienia.class);
    startActivity(intent);
}

public void Historia(View view){
    Intent intent = new Intent(this, Historia.class);
    startActivity(intent);
}

public void zajety(View view){
    Intent intent = new Intent(this, Jazda.class);
    startActivity(intent);
}

} 有时在日志中也有：

08-22 14:33:03.668 10515-10949/com.example.xmisi3g.taxiapp I/FirebaseCrash: Sending crashes

但并非总是如此，并且firebase控制台中没有任何崩溃编辑：附加信息，当onClickListener为空时它不会返回上一个活动，所以onClickListener代码存在问题，但我不知道是什么，请帮忙

按钮返回上一个活动
