オンクラック時にアプリがクラッシュする

Question

numbersIntentリスナーをクリックしてNumbersActivityクラスファイルを開くと、アンドロイドアプリがクラッシュする

NumbersActivityクラスファイルに設定されたアライリスト名 "word"を使用して、whileループを使用している文字列のリストを割り当てています。

NumbersActivityクラスファイルを除いて、他のクラスはうまく見えます。私は理由を理解することができません、誰も助けることができますか？

} 

は、私の活動のメインXMLファイルです

あなたのNumbersActivityで

Answer 1

あなたは、コードの行を次のようしている。

while (index < words.size()); 

はことを削除するようにしてください ";"オペレータの終了時に、次のようにすべきである：同じまたはそのIDを持つ異なるレイアウトのビューがありますがない限り

while (index < words.size())
