使用导航组件折叠工具栏

Question

I'm creating an application that uses the Jetpack navigation Components with multiple fragments and single activity.

The activity contains the FragmentContainerView in addition to the AppBar which includes only a Toolbar that is supposed to be shared between all fragments.

Now what I'm trying to do is to use a Collapsing Toolbar in one of these fragments with an Image to view some details, and make a shared element transition to it.

Is it possible to implement that?

Answer 1

In the themes, set the theme as NoActionBar

<!-- Base application theme. -->
<style name="AppTheme" parent="Theme.AppCompat.Light.NoActionBar"> <!-- changed .DarkActionBar to .NoActionBar -->
   <!-- Customize your theme here. -->
   <item name="colorPrimary">@color/colorPrimary</item>
   <item name="colorPrimaryDark">@color/colorPrimaryDark</item>
   <item name="colorAccent">@color/colorAccent</item>
</style>

Then add a toolbar in each fragment.

You can have a Toolbar or a CollapsingToolbar depending on your need.
