我是Android工作室的新手,但是当我将ImageView拖到我的屏幕上时,我从drawable中选择了我的图片,但后来我收到了一个Render错误说:

The following classes could not be substantiated:
    - android.support.v7.widget.AppCombatImageView

知道问题是什么吗? ImageView在XML中看起来很好:

<ImageView
    android:id="@+id/shopCentre"
    android:layout_width="120dp"
    android:layout_height="64dp"
    app:srcCompat="@drawable/shopping-centre"
    app:layout_constraintTop_toTopOf="parent"
    android:layout_marginTop="30dp"
    android:layout_marginRight="8dp"
    app:layout_constraintRight_toRightOf="parent"
    android:layout_marginLeft="8dp"
    app:layout_constraintLeft_toLeftOf="parent"
    app:layout_constraintHorizontal_bias="0.498" />

build.gradle(项目:应用)

buildscript {
    repositories {
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:2.3.0'

        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }
}

allprojects {
    repositories {
        jcenter()
    }
}

task clean(type: Delete) {
    delete rootProject.buildDir
}
