Is there a tools attribute for ImageView content in Android?

Question

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"/>

Answer 1

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" />
