我正在按照本教程实现导航抽屉。 http://www.androidhive.info/2013/11/android-sliding-menu-using-navigation-drawer/
我可以在ActionBar中设置标题，但没有启动活动。
我已经提到： - setOnItemClickListener() in navigation drawer not working? ，Navigation Drawer setOnItemClickListener not working和许多其他链接。
这是我的xml导航抽屉所在的位置，它也是我的activity_main。

/**
* When using the ActionBarDrawerToggle, you must call it during

*/
@Override
protected void onPostCreate(Bundle savedInstanceState) {
super.onPostCreate(savedInstanceState);
// Sync the toggle state after onRestoreInstanceState has occurred.
mDrawerToggle.syncState();
}
@Override
public void onConfigurationChanged(android.content.res.Configuration newConfig) {
super.onConfigurationChanged(newConfig);
// Pass any configuration change to the drawer toggls
mDrawerToggle.onConfigurationChanged(newConfig);
}
并且抽屉被设置为后退箭头，但我已经编码它显示汉堡包图标如何解决这个问题？
答案 0 :(得分：0)
尝试将此添加到onCreate： mDrawerToggle.syncState（）;
