Android: How to use tools with include layout

Question

How do I use tools:

xmlns:tools="http://schemas.android.com/tools"

With <include>?

I have a layout A that I use tools to populate all the text fields with test data. And I have layout B that use include to copy layout A in to it. How ever when I do that I do not see the test data of A.

How can I see the test data of A included in B?

*Both layouts have xmlns:tools="http://schemas.android.com/tools, I even pushed it to layout tag.

Check this link, Android tools attributes. It should give you an idea as to how to use the tools attributes. Specifically look at the tools:showIn attribute. It basically allows you to render layout_A in layout_B, in which layout_B has <include layout="@layout/layout_A"/> somewhere in the xml.

Here's an example:

layout_A

<?xml version="1.0" encoding="utf-8"?>

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:showIn="@layout/layout_B"
    >

<!-- Your layout code goes here -->

</RelativeLayout>

layout_B

<?xml version="1.0" encoding="utf-8"?>

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    >

<include layout="@layout/layout_A"/>

<!-- Your layout code goes here -->

</RelativeLayout>

Yes. I pulled this code from a project I'm working on. I just changed the names of the layouts. Can you post your code? – Superiority

add layout_width and layout_height to the include tag , otherwise you will find it difficult to arrange it in an RelativeLayout
