RuntimeException:如何解决这个崩溃?是什么引起的?

我在开发人员控制台中显示了这个崩溃报告,我完全不知道它的含义:

第91行代码如下:

setContentView(R.layout.activity_main);

所以我认为它必须处理XML文件。 以下是activity\u main.xml文件:

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:ads="http://schemas.android.com/apk/res-auto"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:fitsSystemWindows="true"
    android:orientation="vertical"
    android:id="@+id/mainview">



    <androidx.constraintlayout.widget.ConstraintLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:orientation="horizontal">

        <androidx.appcompat.widget.Toolbar
            android:id="@+id/toolbar"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:background="@color/main_color"
            android:theme="@style/ThemeOverlay.AppCompat.Dark.ActionBar"
            app:layout_constraintEnd_toEndOf="parent"
            app:layout_constraintHorizontal_bias="0.5"
            app:layout_constraintStart_toStartOf="parent"
            app:layout_constraintTop_toTopOf="parent"
            app:title="My App" />

        <ImageView
            android:id="@+id/search_ico"
            android:layout_width="40dp"
            android:layout_height="40dp"
            android:layout_marginEnd="10dp"
            android:layout_marginRight="10dp"
            android:src="@drawable/ic_search_white_24dp"
            app:layout_constraintBottom_toBottomOf="@+id/toolbar"
            app:layout_constraintEnd_toEndOf="parent"
            app:layout_constraintTop_toTopOf="parent" />

    </androidx.constraintlayout.widget.ConstraintLayout>

    <androidx.drawerlayout.widget.DrawerLayout
        xmlns:android="http://schemas.android.com/apk/res/android"
        xmlns:app="http://schemas.android.com/apk/res-auto"
        android:layout_height="match_parent"
        android:layout_width="match_parent"
        android:id="@+id/drawerLayout">



        <com.google.android.material.navigation.NavigationView
            xmlns:android="http://schemas.android.com/apk/res/android"
            xmlns:app="http://schemas.android.com/apk/res-auto"
            android:layout_width="wrap_content"
            android:layout_height="match_parent"
            android:layout_gravity="start"
            android:id="@+id/navigationView"
            app:itemTextColor="@color/black"
            app:menu="@menu/drawermenu"
            />


    </androidx.drawerlayout.widget.DrawerLayout>
</LinearLayout>

在添加之前,我添加了带有搜索图标last update和约束布局的ImageView。 Android版本6的用户无法打开应用程序。 请帮我解决这个问题,谢谢!
