java.lang.RuntimeException:如何解决此崩溃?是什么原因造成的?

Question

我在我的开发人员控制台中显示了此崩溃报告，但我绝对不知道这意味着什么：

java.lang.RuntimeException:

第 91 行是以下代码：

setContentView(R.layout.activity_main);

所以我认为它必须与 XML 文件做一些事情。 这是activity_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>

我添加了带有搜索图标上次更新和约束布局的 ImageView，在我添加之前一切正常。 使用安卓版本 6 的用户无法打开该应用程序。 请帮我解决这个问题，谢谢！

除了drawable-v24之外，您还必须在项目res目录的drawable文件夹中添加ic_search_white_24dp，以支持低于 24 的设备 API 级别。
