How to set Image resource to ImageView using DataBinding [duplicate]

Question

How can we use data binding in android to put image resource in an ImageView?

  <ImageView             android:id="@+id/is_synced"             android:src="@{model.pending ? @mipmap/pending: @mipmap/synced}"             android:layout_width="wrap_content"             android:layout_height="wrap_content" /> 

I want an image if pending is true and another image if pending is false. But it's showing error.How can I achieve this functionality?

Answer 1

I tried this, and it works for me (buildToolsVersion: 24.0.1):

<ImageView     android:layout_width="50dp"     android:layout_height="50dp"     android:layout_margin="8dp"     android:scaleType="centerInside"     app:imageResource="@{item.avatarResId}"/> 

just use app:imageResource to replace android:src, android:src="@{item.avatarResId}" doesn't works else define a custom @BindAdapter("android:src") for it.

but use app:imageResource doesn't need define a @BindAdapter additionally, because the ImageView has a method called setImageResource(), when you use app:imageResource, it will call setImageResource() automatically.
