複数のコンテキストレベルのタブと関連するフラグメントをユーザーに表示するように、ActionBar で Android タブを処理するにはどうすればよいですか (つまり、より高いレベルでの選択に基づいて、ActionBar タブをあるレベルから別のレベルに変更したい -階層メニューのようなものです)。(理想的には、ソリューションは任意の数の「レベル」をサポートしますが、少なくとも 3 つの「レベル」があればよいでしょう)
注: 回答を適切な順序で並べ替えるには、「最も古い」順に並べ替えます。これにより、パーツが HomeActivity を最後にして適切な場所に配置されます。
これは、FragmentStatePagerAdapter、ViewPager、および ActionBar を使用して、関連付けられたフラグメントを持つ最大 3 つの仮想レベルのタブを表示および管理する ABTabsAdapter クラスと呼ばれるタブ クラスの例です。 . このソリューションは、StackOverflow および Android サポート資料に投稿された他のソリューションからまとめられています。重要なのは、FragmentStatePagerAdapter を使用することです (Android lit に記載されている FragmentPagerAdapter ではなく、デフォルトの Android プロジェクト テンプレートに示されているものです)。また、addTab 関数を介して挿入時にタブが選択されないようにする bIsSet ブール変数の使用にも注意してください。最後に、getItemPosition 関数はフラグメント/ビュー/タブの実際の位置も返すことができることに注意してください。
