Android CircularFloatingActionMenu:システムレベルのボタンとしてデスクトップポップアップメニューとして使用(3)
Android CircularFloatingActionMenuのもう一つの異常な点は、Android CircularFloatingActionMenuがサービスサービスサービスに書き込まれ、上層部のActivityを通じてこのサービスを開始し、Androidシステムレベルの浮上ボタンとしてシステムのデスクトップに浮上して使用できることです.これは一般的なセキュリティソフトウェアでよく見られます.例えば、一部のセキュリティソフトウェアはデスクトップに常駐し、ユーザーにリアルタイムでトラフィック監視などのデータ検出やスイッチボタンを提供しています.現在、Android CircularFloatingActionMenuを使用してこの機能を実現しています.Javaコードですが、ここではバックグラウンドサービスを書くだけで、他のコンポーネントによって呼び出されます.

コード実行効果(サービスとして起動)は、Activityが終了しましたが、サービス起動後の2つのボタンは、動図のようにデバイスデスクトップに常駐しています.
コードに含まれるより多くのカスタムプロパティは、プロジェクトのコードパッケージで具体的に表示できます.
