我在我的 xml文件中有一个错误，我不明白它是在图像croper croper theartofdev库的裁切图像活动的xml文件中。

错误是在<com.theartofdev.edmodo.cropper.CropImageView行，错误显示找不到元素的声明'com.theartofdev.edmodo.cropper.cropimageview'

<?xml version="1.0" encoding="utf-8"?>
<com.theartofdev.edmodo.cropper.CropImageView

   xmlns:app="http://schemas.android.com/apk/res-auto"

我可以查看您的androidManifest.xml文件吗？如果您没有在应用程序标签中添加以下行，则它将不起作用。

<activity android:name="com.theartofdev.edmodo.cropper.CropImageActivity"
            android:theme="@style/Base.Theme.AppCompat" />
