Tag Android Views

Why should you tag Android views?

The Whatfix Mobile SDK uniquely identifies the screen of native apps with the properties of a UI element like resource-id, tag, content-description, etc. on the screen. Adding any of these properties helps in identifying the element and hence the app screen more accurately.

How to add a resource-id to any view?

A resource-id is a unique identifier for any view. It can be added via XML.

<Button
        android:id="@+id/btn_ok"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="Ok">
</Button>

How to add a tag to a view?

Tags are extra information associated with a view. A tag can be added in two ways:

• Using Java
• Using XML

Using Java

button.setTag("tag_btn_ok");

Using XML

<Button
        android:tag="tag_btn_ok"
        android:id="@+id/btn_ok"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="Ok">
</Button>

How to add content-description to a view?

The content-description describes the purpose of a particular view.

The content-description attribute can be added in two ways:

• Using Java
• Using XML

Using Java

imageView.setContentDescription("Arrow Icon");

Using XML

<ImageView
        android:contentDescription="Arrow Icon"
        android:tag="tag_img_arrow_icon"
        android:id="@+id/img_arrow_icon"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:src="@drawable/arrow_icon">
</ImageView>
