私は約10個のフラグメントを持つアプリを持っています。私はコミュニケータを使って情報を渡しました。今、私はアプリを実行すると、主なアクティビティは、Communicatorインターフェイスを実装して以来、すべてのコミュニケータが実装されています。今、oncreateの主な活動で、コミュニケータの中のメソッドで他の機能を使用したいと思っています.6つのメソッドがすべて作成されているか、インスタンスが作成されています。私は断片に戻るボタンを使用しているときに気づいた、私は戻るボタンを6回押して出なければならなかった。修正がありますか、助けてください。アンドロイド - コミュニケータの状態が他の場合は使用できません
Communicatorインターフェイス：
public interface Communicator {
public void requestQuestionsId1(String data);
public void requestQuestionsId2(String data);
public void requestQuestionsId3(String data);
public void requestQuestionsId4(String data);
public void requestQuestionsId5(String data);
public void requestQuestionsId6(String data);
public void show(int data);
}

SO wouldnので、私は、5行方不明requestQuestionsId2,3,4,5（文字列データ）を脱ぎました私はそれを入れさせません。基本的にrequestQuestionId1と同じコードにあります
本当に10個の別々のフラグメントクラスが必要ですか？各質問の論理はほとんど同じではないのですか？ –
私はUIのようなウィザードを実行できるように、10個の別々のフラグメントを使用しています。質問のロジックは次のとおりです。質問から尋ねられた質問を選択し、その答えを "私のMainActivityで使用している "ID"のようなものです。 – masterplox
