recyclerviewで2つの異なるカードビューを使用しているときのエラー

Question

世界の7つの驚異と7つの自然の驚異のリストが必要です。私は単一のrecyclerviewを使用して両方のリストの見出しを追加しようとしています。

header one 
wonder1 
wonder1 
.. 
wonder7 
header two 
n_wonder1 
.. 
n_wonder7 

私は、ヘッダーに異なるcardviewを使用したいが、私はnull pointer exceptionエラーを取得しています。誰が私が作ったミスを教えてもらえますか？ アダプタコードをアップロードしています。ここに。ありがとうございました。アダプタクラスholder.txh.setText(ContValues[position]);で

Answer 1

、ContValues[position]はnullを返しています。それにはデータがありません。それはヌルポインタ例外です。その中に入れてくださいtryとcatch
