フラグメントビューでviewpagerでrecyclerviewを使用しています。フラグメントビューでrecyclerviewが動作していないAndroidビューページ

画面の下にナビを作りたいです。 enter image description here

各ボタンをクリックすると、各フラグメントがframeLayoutに表示されます。

問題は、私はアーティストフラグメント二回目に入力したときに起こります。（私が意図したとおりに最初の時間でそれを見つけるのに表示されます。）をあなたはこの画像で見ることができるようenter image description hereが注目している

はに表示します断片。適切に動作しない画面をスワイプします。それは左または右にスティック移動する必要がありますが、私は指を動かすのを止めるポイントで停止します。

ここは私のソースです。

あなたのアプリケーションのナビゲーション構造のために正確に言うのは難しいですが、あなたの問題に対する解決策は、ArtistBoardFragmentの中のchildFragmentManagerを使用することだと思います。すなわち、代わりに

pageAdapter = new FragmentPagerAdapter(getActivity().getSupportFragmentManager()) ...

の使用

pageAdapter = new FragmentPagerAdapter(getChildFragmentManager()) ...

うわーおかげで非常に多くの〜!! – ssamkyu

getChildFragmentManager（）を使用する必要がある理由を教えてください。お願いします？？違いは何ですか？ – ssamkyu

ChildFragmentManagerは、あなたの場合のように、thmの中に断片があるフラグメント用です。元のコードでは、子フラグメントを埋め込む代わりに親フラグメントを置き換えていました。 – cwbowron
