突出显示listview项目oncreate

Question

我正在尝试在create上突出显示主/详细信息流中的listview项。因此，当活动加载时，我想说第二个项目已经突出显示。我怎么能这样做，代码明智？

到目前为止，我已经尝试过这个：

@Override
public void onItemSelected(int id, String value) 
{
    if (mTwoPane) 
    {
        // In two-pane mode, show the detail view in this activity by
        // adding or replacing the detail fragment using a
        // fragment transaction.
        Bundle arguments = new Bundle();
        arguments.putInt("num", id);
        ((ItemListFragment) getSupportFragmentManager().findFragmentById(R.id.item_list))
       .setActivatedPosition(2); //Setting it here
        arguments.putString("value", value);
        CountingFragment fragment = new CountingFragment();
        fragment.setArguments(arguments);
        getSupportFragmentManager().beginTransaction().replace(R.id.item_detail_container, fragment).commit();
    } 
    else 
    {
        // In single-pane mode, simply start the detail activity
        // for the selected item ID.
        Intent detailIntent = new Intent(this, CountingFragment.class);
        detailIntent.putExtra("num", id);
        detailIntent.putExtra("value", value);
        startActivity(detailIntent);
    }
}

并且不起作用：（
