如何在Floating Action Mode中在Android 9上显示菜单项图标

我有一个类似于以下的Android菜单XML：

<item
    android:id="@+id/action_share"
    android:orderInCategory="100"
    android:icon="@drawable/ic_social_share"
    app:showAsAction="always"
    android@R_473_6964@="" />

<item
    android:id="@+id/action_something_else"
    android:orderInCategory="200"
    android:icon="@drawable/ic_airplanemode_active_black_24dp"
    app:showAsAction="always"
    android@R_473_6964@="" />

我的Android代码类似于：

   private void startActionMode() {
        startActionMode(new android.view.ActionMode.CallBACk2() {
            @Override
            public Boolean onCreateActionMode(final android.view.ActionMode mode,final Menu menu) {
                MenuInflater inflater = mode.getMenuInflater();
                inflater.inflate(R.menu.main,menu);
                mode.settitle("FLOATinG!!!!!");
                return true;
            }

            @Override
            public Boolean onPrepareActionMode(final android.view.ActionMode actionMode,final Menu menu) {
                return false;
            }

            @Override
            public Boolean onActionItemClicked(final android.view.ActionMode actionMode,final MenuItem menuItem) {
                return false;
            }

            @Override
            public void onDestroyActionMode(final android.view.ActionMode actionModE) {

            }
        },android.view.ActionMode.TYPE_FLOATinG);
    }

当我将Android应用程序部署到Android 8设备时,浮动操作模式会根据需要显示图标.

但是,当我将Android应用程序部署到Android 9设备时,浮动操作模式为空,尽管有足够的空间放置图标,并且可以看到图标应位于的背景波纹效果.

如何在Android 9上使用android.view.ActionMode.TYPE_FLOATinG并查看每个菜单项的图标？

我的gradle文件类似于：

apply plugin: 'com.android.application'

android {
    compileSdkVersion 28
    buildToolsVersion "28.0.3"
    defaultConfig {
        applicationId "org.research.development"
        minSdkVersion 23
        targetSdkVersion 28
        versionCode 1
        versionName "1.0"
        testinstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'),'proguard-rules.pro'
        }
    }
}

dependencies {
    implementation fileTree(dir: 'libs',include: ['*.jar'])
    androidTestImplementation('androidx.test.espresso:espresso-core:3.1.0-alpha4',{
        exclude group: 'com.android.support',module: 'support-Annotations'
    })
    implementation 'androidx.appcompat:appcompat:1.1.0-alpha02'
    implementation 'androidx.consTraintlayout:consTraintlayout:1.1.3'
    testImplementation 'junit:junit:4.12'
}

这是我的申请方式
