Is it possible to show a preview layout for ViewPager
in AndroidStudio like in ListView
/RecyclerView
/etc.?
i think it’s not…some of the layouts have no preview while coding or designing …like TabLayout
Answer:
In Andriod studio some views are shown in run time but not in compile time. Think about Frame Layout as a container for fragment transaction. We may place any kind of views on that container in run time. So, it’s not possible to show a view while coding. The viewpager is playing same kind of role here. So, we can’t show a view there before running and actually placing a fragment/other view there.
I hope you are clear now. 🙂
Answer:
This is possible, when putting the ViewPager
into it’s own XML layout resource.
Alike this one can show the desired Fragment
instead of the ViewPager
:
<fragment
android:id="@+id/fragment_viewpager"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout="@layout/fragment_viewpager"
tools:layout="@layout/fragment_preview" />
This also provides the XML preview for the navigation
graph design view.
tools:
layout only works with fragment
, but not with include
.
Answer:
You can achieve design time preview for the ViewPager like so:
- Add an
<include>
with your view as a layout just after the ViewPager - Set its tools:visibility=”visible” and android:visibility=”gone” so that it will be visible at design time but not at runtime.
To show an example:
<androidx.viewpager.widget.ViewPager
android:layout_width="match_parent"
android:layout_height="wrap_content"
app:layout_constraintTop_toBottomOf="@id/tabl1">
</androidx.viewpager.widget.ViewPager>
<include
layout="@layout/fragment_example1"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:visibility="gone"
tools:visibility="visible"
app:layout_constraintTop_toBottomOf="@id/tabl1" />
I hope this helps you
Answer:
For either ListView
and RecyclerView
you can enable preview by adding:
tools:listitem="@layout/view_onboarding_slide"
I cannot find equivalent solution for ViewPager
.
