カスタムアダプタを使用して拡張可能なリストビューを使用して、いくつかのコードを継承しました。別のコンポーネントを使用してトリガーできるように、expandイベントが登録されている場所を特定しようとしています。Expandablelistviewにグループのリスナーが表示されません。ログのprintステートメントを使用して確認できることから、グループがクリックされたときにgetGroupView（）が呼び出されます。ただし、メソッドがどこで呼び出されるか、またはどのように呼び出されるかはわかりません。

これがカスタムアダプタクラスです。

        private String[][] teams;
        private String[] league;
        private final Context context;

        public MyExpandableListAdapter(String[] groups, String[][] children, Context context) {
            this.context = context;
            this.teams = children;
            this.league = groups;
        }

        public Object getChild(int groupPosition, int childPosition) {
            return teams[groupPosition][childPosition];
        }

        public long getChildId(int groupPosition, int childPosition) {
            return childPosition;
        }

         public int getChildrenCount(int groupPosition) {
         return teams[groupPosition].length;
         }

         public TextView getGenericView() {
             AbsListView.LayoutParams lp = new AbsListView.LayoutParams(
             ViewGroup.LayoutParams.FILL_PARENT, 64);

             TextView textView = new TextView(context);
             textView.setLayoutParams(lp);
             textView.setGravity(Gravity.CENTER_VERTICAL | Gravity.LEFT);

             textView.setPadding(56, 0, 0, 0);
             return textView;

次のように、グループのクリックをシミュレートしようとしましたか?

groupView.performClick();

?

編集：

public View getGroupView(int groupPosition, boolean isExpanded,View view, ViewGroup parent) {
    System.out.println("I AM HERE!!!!");

    ...

    if (groupPosition == thePositionIWantToAutomaticallyExpend) {
        view.post(new Runnable() {
             @Override
             public void run() {
                view.performClick(); // This will simulate a user clicking on the view
             }
        });
    }
}
