ボタンを1つだけ投稿しました。そして、これが繰り返されます。このセットアップは完全に正常に機能します。テスト済み、Bean で初期化済み、動作しています。しかし、ここに問題があります。ImageView を TextView の上に移動すると、ImageView id をフェッチするビューの開始行でエラーがスローされます。しかし、元に戻すと、うまく機能します。何か案は?
エラー:
内部の 2 つのメソッドは、単なる文字列の初期化です。
res = getResources();
img = (ImageView)findViewById(R.id.ivRockPic);
tvAnswer = (TextView) findViewById(R.id.tvAnswer);

initAnswerList();
