用于Android中左侧导航抽屉的onitemclicklistner

Question

您好，我在下面创建了左侧导航抽屉。当我们单击父节点时，它将转到父页面。

在父菜单下有一些子菜单，这些子菜单被称为chid节点。

现在我的问题是，如果我单击父级或子级总是转到一个子节点。

有谁能帮助我在哪里做错了

mDrawerList.setOnChildClickListener(new OnChildClickListener() {

            public boolean onChildClick(ExpandableListView parent, View v, int groupPosition, int childPosition, long id) {

                Log.d("CHECK", "child click");

                int index = parent.getFlatListPosition(ExpandableListView.getPackedPositionForChild(groupPosition, childPosition));
                parent.setItemChecked(index, true);
                selectItem(childPosition);
                return true;
            }
        });

private void selectItem(int position) {
        selectedPosition = position;
        mDrawerLayout.closeDrawer(navDrawerView);

        // update the main content by replacing fragments
        Fragment fragment = new PlanetFragment();
        Bundle args = new Bundle();
        args.putInt(PlanetFragment.ARG_PLANET_NUMBER, selectedPosition);
        fragment.setArguments(args);

        FragmentManager fragmentManager = getFragmentManager();
        fragmentManager.beginTransaction().replace(R.id.content_frame, fragment).commit();

        // update selected item and title, then close the drawer
        mDrawerList.setItemChecked(selectedPosition, true);
        setTitle(mPlanetTitles[selectedPosition]);

    }
