覆盖安卓onTextChanged不会改变行为

public class MainActivity extends AppCompatActivity {
    private EditText editText;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        editText = findViewById(R.id.editText);
        editText.addTextChangedListener(new TextWatcher() {
            @Override
            public void beforeTextChanged(CharSequence s, int start, int count, int after) {
                // 文本变化前的操作
            }

            @Override
            public void onTextChanged(CharSequence s, int start, int before, int count) {
                // 文本变化时的操作
                Log.d("TextChange", "Text changed to: " + s.toString());
            }

            @Override
            public void afterTextChanged(Editable s) {
                // 文本变化后的操作
            }
        });
    }
}
