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'
}
}
}

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
