如何在膨胀视图工具栏中显示工具栏图标 android java

Question

I have an inflated view in my activity file and the layout file happens to have a Toolbar widget that I desire to fill up with icons. I have tried to use the code toolbar.Inflate(int resource); but it is not showing up, the toolbar text is also not showing up with toolbar.Title=name; The code for the layout is this one...

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout 
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical"
    android:background="@drawable/chat_background"
    android:baselineAligned="false"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <com.google.android.material.appbar.AppBarLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:theme="@style/AppTheme.AppBarOverlay">

        <androidx.appcompat.widget.Toolbar
            android:id="@+id/toolbar3"
            android:layout_width="match_parent"
            android:layout_height="?attr/actionBarSize"
            android:background="?attr/colorPrimary"
            app:popupTheme="@style/AppTheme.PopupOverlay" />

     </com.google.android.material.appbar.AppBarLayout>
    <EditText
        android:layout_margin="5dp"
        android:layout_alignParentBottom="true"
        android:padding="9dp"
        android:drawableRight="@drawable/tinted_camera"
        android:background="@drawable/rounded"
        android:drawableLeft="@drawable/emoji"
        android:hint="Type a Message"
        android:inputType="textMultiLine"
        android:id="@+id/message_box"
        android:gravity="bottom"
        android:layout_width="match_parent"
        android:layout_height="?attr/actionBarSize"/>

</RelativeLayout>

I tried to inflate the View first, got the ID of my toolbar and tried to inflate the icons to the right of the toolbar as follows but its not working.

            try
            {
                //Inflate our view with the Chat layout
                View chat_view = LayoutInflater.Inflate(Resource.Layout.chat_view, null);
                //define the toolbar
                AndroidX.AppCompat.Widget.Toolbar toolbar = chat_view.FindViewById<AndroidX.AppCompat.Widget.Toolbar>(Resource.Id.toolbar3);
                SetSupportActionBar(toolbar);
                //get the nanme of the current contact
                string name = (string)contact_list.GetItemAtPosition(e.Position);
                toolbar.Title= name;
                //inflate this toolbar
                toolbar.InflateMenu(Resource.Menu.video_menu_item);
                toolbar.InflateMenu(Resource.Menu.call_menu_item);
                toolbar.InflateMenu(Resource.Menu.bars_menu_item);
                toolbar.SetNavigationIcon(Resource.Drawable.back_arrow);
                //build a new alert dialog
                Android.App.AlertDialog.Builder builder = new Android.App.AlertDialog.Builder(this, Android.Resource.Style.ThemeMaterialLightNoActionBarFullscreen);
                builder.SetView(Resource.Layout.chat_view);
                builder.Show();
            }catch (Exception ex)
            {
                Toast.MakeText(this,ex.Message,ToastLength.Short).Show();
            }

How do I succeSsfully make this Toolbar in an inflated view to show up the icons and the text?

Try this:

<androidx.appcompat.widget.Toolbar
        android:id="@+id/toolbar3"
        android:layout_width="match_parent"
        android:layout_height="?attr/actionBarSize"
        android:background="?attr/colorPrimary"
        app:menu="@menu/your_menu"
        app:navigationIcon="@drawable/your_icon" />

<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:id="@+id/new_game"
          android:icon="@drawable/ic_new_game"
          android:title="@string/new_game"
          android:showAsAction="ifRoom"/>
    <item android:id="@+id/help"
          android:icon="@drawable/ic_help"
          android:title="@string/help" />
</menu>

I think you need to check your menu.xml file.
