Java 删除AppBar SearchView提示图标

我正在尝试删除我的应用程序栏搜索视图提示中的图标

因此，我想移除searchView中的放大镜

我是android的初学者

这是我的主要活动布局

<?xml version="1.0" encoding="utf-8"?>
<androidx.drawerlayout.widget.DrawerLayout 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"
    android:id="@+id/drawer_layout"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:fitsSystemWindows="true"
    tools:openDrawer="start">

    <include
        layout="@layout/app_bar_main"
        android:layout_width="match_parent"
        android:layout_height="match_parent" />

    ...

</androidx.drawerlayout.widget.DrawerLayout>

我找不到要编辑什么才能删除此图标

谢谢你的回答

编辑：如果您更方便的话，这里是github

找到了！ 在onCreateOptions菜单方法的my activity.java中，我添加了以下内容：

int magId = getResources().getIdentifier("android:id/search_mag_icon", null, null);
ImageView magImage = searchView.findViewById(magId);
magImage.setLayoutParams(new LinearLayout.LayoutParams(0, 0));

<?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">
    <item
        android:id="@+id/search"
        android:title="Recherche"
        android:icon="@drawable/ic_search"
        app:showAsAction="ifRoom"
        app:actionViewClass="android.widget.SearchView"/>
</menu>

<?xml version="1.0" encoding="utf-8"?>

<searchable xmlns:android="http://schemas.android.com/apk/res/android"
    android:label="@string/app_name"
    android:hint="@string/search_hint"
    android:voiceSearchMode="showVoiceSearchButton|launchRecognizer"
    />
