AndroidRuntime:FatalException：

我真的不知道发生了什么事。在Android Studio上，一切正常，但当我尝试在手机上运行应用程序时，会出现此错误

我正在尝试在android上创建一个OCR应用程序。在Android Studio中查看的代码中没有错误。非常感谢您的帮助

XML代码

<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/topLayout"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:keepScreenOn="true">

<com.example.vb.textreader.proprietary.CameraSourcePreview
    android:id="@+id/preview"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <com.example.vb.textreader.GraphicOverlay
        android:id="@+id/graphicOverlay"
        android:layout_width="match_parent"
        android:layout_height="match_parent" />

</com.example.vb.textreader.proprietary.CameraSourcePreview>

似乎有一个自定义视图com.example.vb.textreader.CameraSourceReview用于导致问题的XML布局文件中

---

检查它的属性和实现。如果它依赖于库，请检查build.gradle中的依赖项。

似乎您正在尝试使用

com.example.vb.textreader.CameraSourceReview

，它必须是您实现的自定义视图。我想到的一件事是检查自定义视图是否恰好位于该位置。

我不确定提供的解决方案是否与您的问题相关，但是

尝试

编译'com.android.support:design:****'

而不是

com.android.support:appcompat-v7:****

当出现此错误时，您可以发布您试图膨胀的布局吗？很可能您正在使用此包中不存在的自定义视图（com.example.vb.textreader.CameraSourcePreview）。是的，您试图膨胀的布局xml，很可能是在调用setContentView（R.layout.your_layout_here）时使用的
