xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:clickable="true"

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

Answer 1

在片段的 onCreate 中，通过调用

启用选项菜单

setHasOptionsMenu(true)

在片段的 oncreate 中而不是在父级中执行此操作 activity

Answer 2

试试这个-

 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
            }
        }
    }
}
