EditTextはRecyclerViewアダプタでは機能しません。ランダムデータがデバイスに表示されます

Question

現在、ユーザーからの入力としてムービー名を取得するアプリケーションを作成しています。その入力後、ムービーのリスト項目を表示する新しい画面が表示され、そのムービーのリストは「http://www.omdbapi.com/」 IMDB。リストの項目（ムービー名）をクリックすると、そのムービーの詳細が別の画面に表示されます。入力が終わる前にすべてがうまくいきました。私はムービー名をハードコードしていますが、今はユーザーが入力して欲しいと思っています。テキストの編集ユーザーからの入力を取得できません。

Answer 1

あなたは活動としてMovieFragmentを扱っている

 Intent intent = new Intent(this, MovieFragment.class); 
     intent.putExtra(Intent.EXTRA_TEXT, input); 
     startActivity(intent); 

しかし、MovieFragmentはフラグメントです。あなたの活動にMovieFragmentを追加/交換する必要があります。

また、setContentView(R.layout.activity_main);する必要が
