Android - 当我写东西时，EditText 给出 IndexOutOfBounds 异常

Question

我正在尝试做一个简单的 fragment ，其中包含一个评级字段和一个用于评论的 EditText。当我单击 EditText 字段并键入内容时出现问题。此时，应用程序崩溃。

                Toast.makeText(getActivity().getApplicationContext(),
                        String.valueOf(ratingBar.getRating()), Toast.LENGTH_LONG).show();

        });

    }

    @Override
    public void onDetach() {
        super.onDetach();
    }
}

有人遇到过类似的问题吗？或者有人知道会发生什么吗？

请在您的编辑 TextView 中添加以下代码

android:inputType="text" 

或

android:inputType="textMultiLine"
