私はアンドロイドスタジオを新しくしています。私は仕事で数日間座っていましたが、断片的に私のボタンを管理しなかったので、期待どおりに働きました。フラグメントコードonClick（）をメインアクティビティとして認識させるにはどうすればよいですか？
マイ構造：私のフラグメントのために
、私はボタンのための私のメソッドが定義されているJavaクラスを持っています。 （onClickの（））
私は私のボタンをクリックすると、私はアプリのクラッシュ、...フラグメント
のフラグメント/ Javaのクラスを/が/知っている含まれている主な活性を持っています。 私は、フラグメントを主なアクティビティにバインドして何かをしなければならないと思います。私はすでにそれを言ったと思った：
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
View rootView = inflater.inflate(R.layout.fragment_sub_page01, container, false);
return rootView;
}
主な活動の中で。
しかし、私は何か重要なことを忘れているようです。誰かが私を助けることができるなら、私はそれを感謝します。
