I could not find a tools attribute to set an example image in a layout for Android. My assumption is that there is no such thing at the moment, at least no direct support.
But I was wondering whether I just did not search well enough or whether there is a workaround for this.
How do you define image placeholders at design time in Android with tools?
Example of a tools attribute for a TextView (i.e. the tools:text attribute for text):
<TextView
android:id="@+id/tv_vote_average"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textSize="16sp"
android:textStyle="bold"
tools:text="8.4/10"/>

ImageView Tutorial With Example In Android In Android, ImageView class is used to display an image file in application. Image file is easy to use but hard to master in Android, because of the various screen sizes in Android devices.
1. id: id is an attribute used to uniquely identify a image view in android. Below is the example code in which we set the id of a image view. <ImageView android:id="@+id/simpleImageView" android:layout_width="fill_parent" android:layout_height="wrap_content" />
Tools attributes reference. Android Studio supports a variety of XML attributes in the tools namespace that enable design-time features (such as which layout to show in a fragment) or compile-time behaviors (such as which shrinking mode to apply to your XML resources).
ImageView class or android.widget.ImageView inherits the android.view.View class which is the subclass of Kotlin. AnyClass.Application of ImageView is also in applying tints to an image in order to reuse a drawable resource and create overlays on background images. Moreover, ImageView is also used to control the size and movement of an image.
It's just straightforward like for the TextView. Just use tools:src to set the image.
<ImageView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
tools:src="@drawable/placeholder" />
