使用maskedEditText库时出现以下错误：
我下载了库，然后单击“文件”->“新建”->“其他”->“现有代码中的Android项目”->“添加文件夹”，选中“将项目复制到工作区”
然后我将库文件夹添加到我的项目中：
当我运行时，我有ClassNotFoundException
我的XML

最佳答案

尝试将命名空间更改为“maskededitext.maskededitext”。我们可以在“references/maskededitext”中看到名称空间。
例子：

        <MaskedEditText.MaskedEditText
                android:layout_width="match_parent"
                android:layout_height="wrap_content"
                mask:mask="+# (###) ##-##"
                android:id="@+id/email" />
