Android expandablelistview GroupView如果展开其他GroupView，则不会显示选择onClick

Question

我有4个组的ExpandableListView。如果位置0处的组被展开，那么当我单击位置1处的组时，该组的选择（红色）不会显示。如果我在第3位扩展组，然后在第2位扩展，一切都没问题，选择就会显示出来。我有4个听众，听取组选，扩展，折叠和子按下。在选定，展开和折叠的侦听器上调用displayView（）方法。然后根据位置方法应该选择组并显示新的片段或者不显示。我知道方法得到正确的位置，应该选择。怎么了？

我的列表听众：

mDrawerList.setOnGroupClickListener(new ExpandableListView.OnGroupClickListener() {
    @Override
    public boolean onGroupClick(ExpandableListView parent, View v,
                                int groupPosition, long id) {
        displayView(groupPosition);
        return false;
    }
});

mDrawerList.setOnGroupExpandListener(new ExpandableListView.OnGroupExpandListener() {
    @Override
    public void onGroupExpand(int groupPosition) {
        displayView(groupPosition);    
    }
});

mDrawerList.setOnGroupCollapseListener(new ExpandableListView.OnGroupCollapseListener() {
    @Override
    public void onGroupCollapse(int groupPosition) {
        displayView(groupPosition);    
    }
});

mDrawerList.setOnChildClickListener(new ExpandableListView.OnChildClickListener() {
    @Override
    public boolean onChildClick(ExpandableListView parent, View v,
                                int groupPosition, int childPosition, long id) {
        return false;
    }
});

我的displayView方法：

private void displayView(int position) {
    // update the main content by replacing fragments
    android.support.v4.app.Fragment fragment = null;
    switch (position) {
        case 1:
            fragment = new Eat();
            break;
        case 3:
            fragment = new About();
            break;
        default:
            break;
    }
    mDrawerList.setItemChecked(position, true);
    mDrawerList.setSelection(position);
    //here method have a right position of a group
    if (fragment != null) {
        android.support.v4.app.FragmentManager fragmentManager = getSupportFragmentManager();
        fragmentManager.beginTransaction()
                .replace(R.id.frame_container, fragment).commit();
        // update selected item and title, then close the drawer
        setTitle(navMenuTitles[position]);
        mDrawerLayout.closeDrawer(mDrawerList);
    }
}
