TextView 未初始化，即使它已初始化

Question

我在这件事上失去了理智。我收到错误消息“变量‘joiningDate’可能尚未初始化”。这是代码：

private TextView joiningDate;

@Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_user_registration);
        joiningDate = findViewById(R.id.joiningDate);
    }

private void saveData() {
        String name = editTextName.getText().toString();
        String email = editTextEmail.getText().toString();
        String phone = editTextPhone.getText().toString();
        String userId = editTextUserId.getText().toString();
        String password = editTextPassword.getText().toString();
        String joiningDate = joiningDate.getText().toString();

        // Now send this data to your server
        sendDataToServer(name, email, phone, userId, password, joiningDate);
    }

请帮我解决它。

Answer 1

您使用与文本视图相同的字符串名称。使用不同的名称而不是 joinDate

String joinDate = joiningDate.getText().toString();
