我正在开发一个Android应用程序,我正在尝试在androidstudio中实现设计布局 Image in Android Studio Preview

但当我在真正的设备上运行它时,它的布局就像 Design In Real Device

在Android工作室中,我使用nexus4来设计布局,我的手机分辨率是720x1280。这是我的xml代码

<android.support.constraint.ConstraintLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context="com.example.usmanali.childsafety.MainActivity">

<LinearLayout
    android:layout_width="match_parent"
    android:layout_height="275sp"
    tools:ignore="MissingConstraints"
    tools:layout_editor_absoluteX="0dp"
    tools:layout_editor_absoluteY="3dp">

    <ImageView
        android:id="@+id/imgschool"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:background="@drawable/im"
        android:contentDescription="@string/todo" />
</LinearLayout>
<LinearLayout
    android:layout_width="match_parent"

    tools:layout_editor_absoluteX="0dp"
    tools:layout_editor_absoluteY="278dp">
    <ImageView
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:src="@drawable/download" />
</LinearLayout>

<RelativeLayout

    tools:ignore="MissingConstraints">

    <Button
