You need to remove group checkable behaviour attribute and put only put checkable = true in your item, it will works. Best of luck!!

Navigation Drawer items not showing anything [duplicate]

Android studio 3.5 refactor issue
(9 answers)
Closed 3 years ago.
I have updated the Android Studio to version 3.5 from August 9 2019. I have tried to get familiar with new idea for navigation drawer using Navigation Component. I created the new project and chose the Navigation Drawer Activity at start. After that, I have tried to run the app to see if everything works fine but the drawer menu doesn't work. The drawer gets open but when I click on any available items it just close the drawer not opening proper fragment. I have also tried to set different fragment as a Start Destination and it works fine, the correct fragment gets open at start correctly however the drawer menu still doesn't work.
What am I missing? How can I make it work?
Code comes straight from the fresh new Navigation Drawer Activity:

Persistent Bottom Sheet with rounded corners in Android crashes when used in a card view

I have created a persistent bottom sheet in android with the intent of displaying a ListView containing additional information about locations. I want the sheet to have rounded corners. I got a ton of results for modal dialog but none for persistent. Is it possible or should I use the modal version?
As suggested in an answer here, I tried wrapping it in a card view but the app crashes when I try to open the fragment.

With the new Material Component library you can customize the shape of your component using the shapeAppearanceOverlay attribute.
You can use something like:
<!-- BottomSheet -->
<style name="CustomBottomSheet" parent="Widget.MaterialComponents.BottomSheet">
<item name="shapeAppearanceOverlay">#style/CustomShapeAppearanceOverlay.MaterialComponents.BottomSheet</item>
....
</style>
<style name="CustomShapeAppearanceOverlay.MaterialComponents.BottomSheet" parent="">
<item name="cornerSizeTopRight">16dp</item>
<item name="cornerSizeTopLeft">16dp</item>
<item name="cornerSizeBottomRight">0dp</item>
<item name="cornerSizeBottomLeft">0dp</item>
</style>
Then you can apply this style to your single component or your theme app.
<!-- Base application theme. -->
<style name="AppTheme" parent="Theme.MaterialComponents.Light">
...
<item name="bottomSheetStyle">#style/CustomBottomSheet</item>
</style>
If you are using a non-modal bottom sheet just apply the style. For example:
<LinearLayout
android:id="#+id/standardBottomSheet"
app:layout_behavior="com.google.android.material.bottomsheet.BottomSheetBehavior"
style="?attr/bottomSheetStyle"
...>

U can add shape for you bottom sheet background background
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle">
<solid android:color="#color/you_color"/>
<corners
android:bottomRightRadius="2dp"
android:bottomLeftRadius="2dp"
android:topLeftRadius="2dp"
android:topRightRadius="2dp"/>
</shape>

You could also use the app:shapeAppearance attribute:
Create a ShapeAppearance in styles.xml:
<resources>
...
<style name="BottomSheetShapeAppearance">
<item name="cornerFamily">rounded</item>
<item name="cornerSizeTopLeft">16dp</item>
<item name="cornerSizeTopRight">16dp</item>
</style>
</resources>
Set the app:shapeAppearance attribute on the BottomSheet component:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
style="#style/Widget.MaterialComponents.BottomSheet"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
app:layout_behavior="com.google.android.material.bottomsheet.BottomSheetBehavior"
app:shapeAppearance="#style/BottomSheetShapeAppearance">
...
</LinearLayout>
Here's how it looks:

For the menu, my XML is here. I'm using the v7 compatibility library.
<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools" tools:context=".MainActivity">
<item android:id="#+id/action_settings"
android:title="#string/action_settings"
android:orderInCategory="100" app:showAsAction="never"
/>
<item
android:id="#+id/menu_item_share"
android:title="Share"
app:actionProviderClass="support.v7.android.widget.ShareActionProvider"
app:showAsAction="never"/>
</menu>

Try replacing your menu with
<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools" tools:context=".MainActivity">
<item android:id="#+id/action_settings"
android:title="#string/action_settings"
android:orderInCategory="100" app:showAsAction="never"
/>
<item
android:id="#+id/menu_item_share"
android:title="Share"
app:actionProviderClass="support.v7.android.widget.ShareActionProvider"
android:icon="#android:drawable/ic_menu_share"
app:showAsAction="ifRoom"/>
</menu>
Changes - Add icon to share and change showAsAction to ifRoom
Cheers,
Sha
