に関連するRecyclerViews Android

Question

私は初心者であり、この問題を解決するためにあなたの助けが必要です。RecyclerViewのビューの複製に直面しています。ビューが5回再生されるたびに、ビューが自動的に繰り返されます。 androiddevも同様に役立つことはありません。 基本的に私は学生の意見を取り込むためにフィードバックフォームを作成しています。これが私の道に入り、解決できません。 問題の要点を得るためにスクリーンショットを添付しています。 以下のスクリーンショットの比較コードをご覧ください。

Important thing to notice here is that the multiple viewholders are needed to be checked and aligned 
with respect to the position and viewtype of the layout 
Viewtype: returns default value 0 for similar layout so we overrided it with two values 
one for the cardview and one for the Master submit section 
Pl note :::: Always create different child classes and extend it to the master class to get better result and 
better judge of the execution taking place. 
OncreateViewholder creates and inflates the view so here we need to distinctly create different objects of 
child classes to get different results

Answer 1

onBindViewHolderビューが をバインドするたびに実行されるためとして onBindViewHolder外のごbuttonviewホルダーを宣言してみてください。これは

Answer 2

を変更しようと繰り返すようにあなたの意見を引き起こしている可能性がありますclassCardAdapterクラスに

public classCardAdapter extends RecyclerView.Adapter<classCardAdapter.RecyclerViewHolder> 

を拡張し、方法変更：

@Override 
public RecyclerViewHolder onCreateViewHolder(ViewGroup parent, int viewType) { 
//all stuff 

} 

をすべてのビューを保持するRecyclerViewHolderのクラスを作成します。データ
