Android：导航抽屉选择项目不同位置0

Question

我他创建了一个导航抽屉，但我不知道默认选择选项 3 和应用程序启动时文本设置为加粗抽屉。我尝试mDrawerList.setItemChecked(2, true); 加载抽屉，但始终选择选项 1。这是我的代码：

MainActivity.java

private void cargarDrawerLayout(Bundle b) {

    mTitle = mDrawerTitle = getTitle();

    textosMenuLateral = getResources().getStringArray(R.array.nav_drawer_items);

    iconosMenuLateral1 = getResources()
            .obtainTypedArray(R.array.iconos_menu_lateral1);

    iconosMenuLateral2 = getResources()
            .obtainTypedArray(R.array.iconos_menu_lateral2);

    mDrawerLayout = (DrawerLayout) findViewById(R.id.drawer_layout);
    mDrawerList = (ListView) findViewById(R.id.list_slidermenu);

    int[] colores = {0, 0xFFFFFFFF, 0};
    mDrawerList.setDivider(new GradientDrawable(Orientation.RIGHT_LEFT, colores));
    mDrawerList.setDividerHeight(4);

    navDrawerItems1 = new ArrayList<NavDrawerItem>();

    navDrawerItems1.add(new NavDrawerItem(textosMenuLateral[0], iconosMenuLateral1.getResourceId(0, -1)));
    navDrawerItems1.add(new NavDrawerItem(textosMenuLateral[1], iconosMenuLateral1.getResourceId(1, -1)));
    navDrawerItems1.add(new NavDrawerItem(textosMenuLateral[2], iconosMenuLateral1.getResourceId(2, -1)));
    navDrawerItems1.add(new NavDrawerItem(textosMenuLateral[3], iconosMenuLateral1.getResourceId(3, -1)));

    navDrawerItems2 = new ArrayList<NavDrawerItem>();

    navDrawerItems2.add(new NavDrawerItem(textosMenuLateral[0], iconosMenuLateral2.getResourceId(0, -1)));
    navDrawerItems2.add(new NavDrawerItem(textosMenuLateral[1], iconosMenuLateral2.getResourceId(1, -1)));
    navDrawerItems2.add(new NavDrawerItem(textosMenuLateral[2], iconosMenuLateral2.getResourceId(2, -1)));
    navDrawerItems2.add(new NavDrawerItem(textosMenuLateral[3], iconosMenuLateral2.getResourceId(3, -1)));

    iconosMenuLateral1.recycle();

    mDrawerList.setOnItemClickListener(new SlideMenuClickListener());

    adapter = new NavDrawerListAdapter(getApplicationContext(),
            navDrawerItems1,
            perfilObj.getColor());
    mDrawerList.setAdapter(adapter);

    mDrawerToggle = new ActionBarDrawerToggle(
            this, 
            mDrawerLayout,
            R.drawable.boton_drawerlayout, //nav menu toggle icon
            R.string.app_name, // nav drawer open - description for accessibility
            R.string.app_name // nav drawer close - description for accessibility
    ) {
        public void onDrawerClosed(View view) {
            getActionBar().setTitle(mTitle);
            // calling onPrepareOptionsMenu() to show action bar icons
            invalidateOptionsMenu();
        }

        public void onDrawerOpened(View drawerView) {
            getActionBar().setTitle(mDrawerTitle);
            // calling onPrepareOptionsMenu() to hide action bar icons
            invalidateOptionsMenu();
        }
    };
    mDrawerLayout.setDrawerListener(mDrawerToggle);

    if (b == null) {
        opcionesPanelLateral(0);
    }

}

private class SlideMenuClickListener implements ListView.OnItemClickListener {
    @Override
    public void onItemClick(AdapterView<?> parent, View view, int position,
            long id) {
        TextView textView = (TextView) view.findViewById(R.id.title);
        textView.setTypeface(null, Typeface.BOLD);

        ImageView imgIcon = (ImageView) view.findViewById(R.id.icon);
        imgIcon.setImageResource(navDrawerItems2.get(position).getIcon());    

        opcionesPanelLateral(position);
    }
}


@Override

    getMenuInflater().inflate(R.menu.main, menu);
    return true;

更新这个方法

if (b == null) {
    opcionesPanelLateral(0);
}

到

if (b == null) {
    opcionesPanelLateral(2);
}

您可以在此处传递任何选项以进行默认选择
