运行 Android Studio 2.1.2、Windows 7。

我用 NestedScrollView 替换了 ScrollView，现在我得到了

android.view.InflateException: Binary XML file line #2: Error inflating class NestedScrollView

java.lang.ClassNotFoundException：在路径上找不到类“android.view.NestedScrollView”：/data/app/com.assemblyguide.remote-48.apk

...当我对该 XML 文件调用 SetContentView() 时。当我只有一个 ScrollView 时，我没有得到它。

我试过清理，使缓存失效并重建。XML 看起来像这样。. .

完整的类名是android.support.v4.widget.NestedScrollView. 替换<NestedScrollView>元素，<android.support.v4.widget.NestedScrollView>它应该可以正常工作。确保您的 build.gradle 文件中也有 v4 支持库。

如果使用 androidx，请替换<NestedScrollView>或完整的类<android.support.v4.widget.NestedScrollView>名
<androidx.core.widget.NestedScrollView>

将其更改为

    <androidx.core.widget.NestedScrollView
        android:layout_width="match_parent"
        android:layout_height="wrap_content">

您需要在依赖项中添加此行：

compile 'com.android.support:support-v4:23.4.0'

正如国际象棋多克所说，它android.support.v4.widget.NestedScrollView不是NestedScrollView

当我使用 androidx.core.widget.NestedScrollView 时，我删除了这一行，它会正常工作。当我添加这个时，应用程序会崩溃（我的布局在 NestedScrollView 中也有 recyclerview）

android:nestedScrollingEnabled="false"

NestedScrollView是在22.1.0 版本
中添加的， 您应该按以下方式使用 NestedScrollView：

<?xml version="1.0" encoding="utf-8"?>
<android.support.v4.widget.NestedScrollView xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

</android.support.v4.widget.NestedScrollView>

build.gradle(模块)

dependencies {
    implementation 'com.android.support:appcompat-v7:<greater than or equal to 22.1.0>'
    //...
}

一个愚蠢的错误可能是

android:nestedScrollingEnabled="false"

在 NestedScrollView 本身上设置。
