具有多个屏幕的Android Inflate例外

Question

我正在创建一个支持多种屏幕尺寸的应用。因此我创建了3个布局文件夹，即布局，布局小和布局大。 但是当我在不同的手机上运行这个应用程序时，它会在不同的屏幕上崩溃并显示二进制膨胀异常。 此外，在android studio的预览窗口中，它没有从普通文件夹中选择布局。它显示了布局和布局小的布局。 请指出我的错误，并提前感谢。 为其中一个屏幕添加layout-large

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:background="@drawable/blue_bg"
    android:orientation="vertical"
    xmlns:android="http://schemas.android.com/apk/res/android">

    <ImageView
        android:layout_width="200dp"
        android:layout_height="150dp"
        android:src="@drawable/logo"
        android:layout_marginLeft="30dp"
        android:layout_marginTop="10dp"
        android:id="@+id/iv_logo"/>
    <LinearLayout
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:orientation="horizontal"
        >
        <TextView
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:text="be connected."
            android:textColor="#ffffff"
            android:layout_marginLeft="30dp"
            android:id="@+id/tv_connect"
            android:textSize="54sp"
            android:textStyle="bold"/>
        <TextView
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:text="be one."
            android:textSize="54sp"
            android:textStyle="bold"
            android:layout_marginLeft="5dp"
            android:textColor="#303359"/>
    </LinearLayout>
    <VideoView
        android:layout_width="match_parent"
        android:layout_height="350dp"
        android:layout_marginLeft="30dp"
        android:layout_marginTop="50dp"
        android:layout_marginRight="30dp"
        android:id="@+id/video"/>
</LinearLayout>

这是错误日志
