如何在单击另一个RecycerView中的项时显示RecycerView视图

Question

Answer 1

是的...使用Expandablelistview解决了我的问题。以下是Expandablelistview的链接https://www.androidhive.info/2013/07/android-expandable-list-view-tutorial/

本教程将显示所有项目的展开，所以替换主活动中的代码来展开一个项目。

        expListView.setOnGroupExpandListener(new OnGroupExpandListener() {

        // TODO Colapse Here Using this... in android
        int previousGroup = -1;
        boolean flag = false;

        @Override
        public void onGroupExpand(int groupPosition) {

        //  Log.e("keshav", "onGroupClick is -> " + groupPosition);

            Toast.makeText(getApplicationContext(),
                    listDataHeader.get(groupPosition) + " Expanded",
                    Toast.LENGTH_SHORT).show();

            if (groupPosition != previousGroup && flag) {
                expListView.collapseGroup(previousGroup);
            }
            previousGroup = groupPosition;

            flag = true;

        }
    });
