I'm beginning with android studio and I can't see the elements (Buttons,TextView,..) I drag and drop in my Design page in activity_main.xml page. Those elements are present in my XML file and I can see them when I run my app on my device but I don't know how I can see them on "Design and Blueprint" page.

Thanks for your help.

This is my xml code :

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

        app:layout_constraintTop_toTopOf="parent" />

        app:menu="@menu/navigation" />

        tools:layout_editor_absoluteY="29dp" />

        app:layout_constraintGuide_begin="20dp" />


And my canvas is totally empty.


I'v got 2 errors :

  • Render Problem : Failed to find style 'bottomNavigationStyle' in current theme Tip: Try to refresh the layout.

  • Missing Constraints in ConstraintLayout : This view is not constrained. It only has designtime positions, so it will jump to (0,0) at runtime unless you add the constraints

You can solve this problem by fixing the styles.xml file.

Then you just have to add Base in this code:

<style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">

The final code:

<style name="AppTheme" parent="Base.Theme.AppCompat.Light.DarkActionBar">

If you have the same error as this page, you should change to in build.gradle(Module: app) and and click File -> Invalidate Caches / Restart. Now everything is OK.

Of course you need internet access to download
