如何在自定义Android键盘上禁用拼写检查？

public class CustomKeyboard extends InputMethodService {
    // ...

    @Override
    public View onCreateInputView() {
        // 创建自定义键盘布局
        View keyboardView = getLayoutInflater().inflate(R.layout.custom_keyboard, null);

        // 获取EditText或TextView的InputConnection对象
        EditText editText = keyboardView.findViewById(R.id.editText);
        InputConnection inputConnection = editText.onCreateInputConnection(new EditorInfo());

        // 创建自定义的InputConnectionWrapper
        InputConnectionWrapper inputConnectionWrapper = new InputConnectionWrapper(inputConnection, false) {
            @Override
            public boolean shouldCheckSpelling() {
                // 禁用拼写检查
                return false;
            }
        };

        // 将自定义的InputConnectionWrapper设置给InputConnection
        editText.setInputConnection(inputConnectionWrapper);

        return keyboardView;
    }

    // ...
}
