java - 将 CharSequence 转换为可编辑

Question

我正在从 getText() 中返回带有 CharSequence 的 EditText 视图的加密值。

但发生 IllegalArgumentException: Invalid offset: -1。有效范围为 [0, 49] 异常

如果我将 InputType 设置为 XML 中的数字，它就可以工作。喜欢-

<com.shubham.nbsdk.SecureEditText
    android:id="@+id/xpay_encrypt_edittext"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:hint="Enter Text to Encrypt"
    android:inputType="number"/>

但是有问题android:inputType="text"

@Nullable
    @Override
    public Editable getText() {
    CharSequence encryptedText = 
    secureSDKImpl_inner.EncryptText(PlainText.toString());
       return new Editable.Factory().newEditable(encryptedText); 
    }

我想我做错了什么

return new Editable.Factory().newEditable(encryptedText);

将 CharSequence 转换为 Editable 的任何其他选项
