I have already created a custom layout for badge counter and on inflating menu my cart icon is not working my codes are below.

cart Item Layout

<FrameLayout
style="?attr/actionButtonStyle"
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:clickable="true"
android:background="?attr/selectableItemBackground"
android:clipToPadding="false"
android:focusable="true">

<ImageView
    android:id="@ id/badge_icon_button"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_gravity="center"
    android:src="@drawable/ic_cart"/>

<TextView
    android:id="@ id/cart_badge_text_view"
    android:layout_width="20dp"
    android:layout_height="20dp"
    android:layout_gravity="right|end|top"
    android:layout_marginEnd="-5dp"
    android:layout_marginRight="-5dp"
    android:layout_marginTop="3dp"
    android:background="@drawable/badge_cart_bg"
    android:gravity="center"
    android:padding="3dp"
    android:textColor="@android:color/white"
    android:text="0"
    android:textSize="10sp"/>

toolbar menu

<item android:id="@ id/cart"
    android:title=""
    app:showAsAction="always"
    app:actionLayout="@layout/custom_cart_item_layout"
    android:icon="@drawable/ic_cart"/>

Code in fragment code

CodePudding user response：

In the onCreate of your fragment, enable options menu by calling

setHasOptionsMenu(true)

Do this in the fragment's oncreate not in the parent activity

CodePudding user response：

Try this once-

 override fun onViewCreated(view: View, savedInstanceState: Bundle?) {
        ...
        myToolbar.inflateMenu(R.menu.sample_menu)
        myToolbar.setOnMenuItemClickListener {
            when (it.itemId) {
                R.id.action_settings -> {
                    // Navigate to settings screen
                    true
                }
                R.id.action_done -> {
                    // Save profile changes
                    true
                }
                else -> false
            }
        }
    }
}
