expandable.expand(); not able to call
The library build includes app icons, which makes compilation fail for the project which is included into, because of a manifest merger error, as shown below:
C:\Users\Guillermo\...\app\src\main\AndroidManifest.xml:42:9-41 Error:
Attribute application@icon value=(@mipmap/...) from AndroidManifest.xml:42:9-41
is also present at [com.robertlevonyan.view:MaterialExpansionPanel:2.0.8] AndroidManifest.xml:13:9-43 value=(@mipmap/ic_launcher).
Suggestion: add 'tools:replace="android:icon"' to <application> element at AndroidManifest.xml:39:5-244:19 to override.
C:\Users\Guillermo\...\app\src\main\AndroidManifest.xml:45:9-46 Error:
Attribute application@roundIcon value=(@mipmap/...) from AndroidManifest.xml:45:9-46
is also present at [com.robertlevonyan.view:MaterialExpansionPanel:2.0.8] AndroidManifest.xml:15:9-54 value=(@mipmap/ic_launcher_round).
Suggestion: add 'tools:replace="android:roundIcon"' to <application> element at AndroidManifest.xml:39:5-244:19 to override.
Icons shouldn't be included if the project is an Android libary.
Workaround: If you're using this library, and you're affected with this issue, you have to add the following line to your AndroidManifest.xml in your <application /> node: tools:replace="android:icon,android:roundIcon"
First, thank you for the solution. I am enjoying using it, but it looks like there is a bug related to dynamic resizing.
When the content view has child components that resizes automatically, like multiline TextInputEditText or RecyclerView, the panel expanded is not automatically resized, hiding its child components. I can't call the expand method programatically because it's a private method.
Can you help me?
Thank you!
Hi, I've been having trouble trying to add a recyclerview inside the expandable content layout.
If I have normal views it works fine, however when I add a recyclerview, it doesn't recalculate the size of the expandable view and it ends up cutting off other views inside.
Here is my code for the expandable layout, the part that doesn't work is the recyclerTeam1 and recyclerTeam2:

how can one hide Expandable Icon ?
Or Expandable View without Expandable Icon ?
where you define your ExapandingListener? I can`t find that code.
Hello,
Great library. But I want to panel to be expanded by default but I am unable to expand it. Tried using the method the expand() but it is now private.
Hi
the panel is really great ! sadly i face some issue as the inner ChipGroup doesn't grow as it does without this ExpansionPanel...
when adding a number of Chips inside the ChipGroup , i can't see more than the 1st line of chips ...
i know i didn't use the include, but that seemed to work as below...
anything i miss ?
thanks a lot !
my xml:
<com.robertlevonyan.views.expandable.Expandable
android:id="@+id/expandable"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:padding="10dp"
app:exp_backgroundColor="@color/colorPrimary"
app:exp_headerBackgroundColor="@android:color/white"
app:layout_constrainedHeight="false">
<TextView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="labels" />
<com.google.android.material.chip.ChipGroup
android:id="@+id/chipslayout"
android:layout_width="match_parent"
android:layout_height="wrap_content">
</com.google.android.material.chip.ChipGroup>
</com.robertlevonyan.views.expandable.Expandable>
Hi, thanks for this solution. It works for the most part. I followed what's on the README but this one is not working for me. Did I miss something?
Cheers
