Neil Davies の CoverFlow Widget v2 をフラグメント アクティビティとして使用しようとしています。私はこのようなものを期待していますここに画像の説明を入力

代わりに私はこれを手に入れましたここに画像の説明を入力

私の実装では明らかに何かが間違っていますが、エラーやクラッシュが見られないため、どこを見ればよいかわかりません。以下の Anywho は Java および xml コードです

たくさんのコード:-)

TestFragment2.javaには、1つの大きなエラー(CoverFlowが表示されない理由を説明できます)ともう1つの小さなエラーがあるようです。

onCreateViewメソッドでは、ビュー階層にTestFragment2を追加するのを忘れています。mycoverFlowこれをメソッドに追加して、onCreateViewこれで(部分的に)修正されるかどうかを確認します。

((ViewGroup)myView).addView(mycoverFlow, LayoutParams.MATCH_PARENT, LayoutParams.MATCH_PARENT);

(多分MATCH_PARENTはWRAP_CONTENTでなければなりません)。

小さなエラーは、このメソッドでは2回onCreateView呼び出すことです。mycoverFlow.setAdapter(...)最後のものだけが効果を発揮します。最初のものを削除します。
