如何在方向改变时修复TextWatcher？

public class MainActivity extends AppCompatActivity {
    private EditText editText;
    private String savedText;

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

        editText = findViewById(R.id.editText);

        if (savedInstanceState != null) {
            savedText = savedInstanceState.getString("text");
            editText.setText(savedText);
        }

        editText.addTextChangedListener(new TextWatcher() {
            @Override
            public void beforeTextChanged(CharSequence s, int start, int count, int after) {
                savedText = editText.getText().toString();
            }

            @Override
            public void onTextChanged(CharSequence s, int start, int before, int count) {
                if (!editText.getText().toString().equals(savedText)) {
                    // 文本内容发生了改变，进行修复操作
                    // 例如重新加载数据或重新设置监听器
                }
            }

            @Override
            public void afterTextChanged(Editable s) {
            }
        });
    }

    @Override
    protected void onSaveInstanceState(Bundle outState) {
        super.onSaveInstanceState(outState);
        outState.putString("text", editText.getText().toString());
    }

    @Override
    protected void onRestoreInstanceState(Bundle savedInstanceState) {
        super.onRestoreInstanceState(savedInstanceState);
        savedText = savedInstanceState.getString("text");
        editText.setText(savedText);
    }
}
