私はこのコードを約 1 日いじっていますが、何が問題なのかわかりません。私はいくつかを受け取り、応答からJSON動的に作成しようとしています。Viewsコードを投稿してから、問題を説明します。

問題は、どれもViews作成されていないことです。投稿からわかるようにlogcat、アプリケーションはJSON応答を取得し、それらを識別します。ただしonPostExecute()、Views. @dmonが提案した変更を行った後、保存している結果が範囲外になると考える必要があります。theResult.getType()それ以外の場合、メソッドを呼び出すと、値が含まれます。現在、明らかにそうではありません。
問題を知っていると思っていても、その理由がわかりません。どんな助けや洞察も大歓迎です。
