私は、DialogAlertのRecyclerViewに何らかの問題があります。そのだけでいくつかのEditTextを示しているためDialogAlert内のRecyclerViewの作成方法
私の最初のDialogAlertその作業罰金：私は以下のようなカスタムダイアログの警告を持っています。しかし、画像情報（drawTableはeditTextに残っています）をクリックするとエラーが発生します。その常に強制停止。私はthisとthisを読むが、それは動作しない。これは私のログです：
E/InputEventReceiver: Exception dispatching input event.
E/MessageQueue-JNI: Exception in MessageQueue callback: handleReceiveCallback
E/MessageQueue-JNI: java.lang.NullPointerException: Attempt to invoke virtual method 'void android.support.v7.widget.RecyclerView.setAdapter(android.support.v7.widget.RecyclerView$Adapter)' on a null object reference

私は公共のクラスでRecyclerViewを宣言しようとするが、私はまだ同じエラーを取得します。すべての答えが私を助けます。おかげ
なぜあなたは相対レイアウトをしませんか？ – Sanf0rd
2回目のアラートダイアログでは？ 2番目のalertdialogでは、私はLinearLayoutManagerでRecyclerViewが必要なので、いくつかのJSONデータを取得したいのですが、このエラー –
