我有应该首先加载的主要活动，如果要启动新的活动/片段，则应选择抽屉项目，但由于某种原因，在主要活动创建之前调用抽屉项目方法甚至发生创建的抽屉项目被选中...基本上不确定为什么它一直让我直接进入profileactivity。
以下是主要活动代码：
public class MainActivity extends FragmentActivity
implements NavigationDrawerFragment.NavigationDrawerCallbacks {
//Starter fragment
private StarterFragment starterFragment;
// Alert Dialog Manager
AlertDialogManager alert = new AlertDialogManager();
/**
* Fragment managing the behaviors, interactions and presentation of the navigation drawer.
*/
private NavigationDrawerFragment mNavigationDrawerFragment;
/**
* Used to store the last screen title. For use in {@link #restoreActionBar()}.
*/

//Session
private SessionManager sessionM;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);

setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);
mNavigationDrawerFragment = (NavigationDrawerFragment)
getFragmentManager().findFragmentById(R.id.navigation_drawer);
mTitle = getTitle();
// Set up the drawer.
mNavigationDrawerFragment.setUp(
R.id.navigation_drawer,
(DrawerLayout) findViewById(R.id.drawer_layout));
//set default page to open home page
onNavigationDrawerItemSelected(1);
}
private void onSessionStateChange(Session session, SessionState state, Exception exception) {
//user is authenticated
if (state.isOpened()) {
Log.i("Main", "Logged in...");
//user is not authenticated
} else if (state.isClosed()) {
sessionM.logoutUser();
Log.i("Main", "Logged out...");
}
}

个人资料活动：

mPager.setOnPageChangeListener(new ViewPager.SimpleOnPageChangeListener() {
@Override
public void onPageSelected(int position) {
// When changing pages, reset the action bar actions since they are dependent
// on which page is currently active. An alternative approach is to have each
// fragment expose actions itself (rather than the activity exposing actions),
// but for simplicity, the activity provides the actions in this sample.
invalidateOptionsMenu();
}
});
firstName.setText(firstSess);
age.setText(ageSess);
status.setText(statusSess);
}
@Override

如果需要其他任何内容，请告诉我，此行Log.d（Constants.DEBUG，“IN MAIN ACTIVITY（LOADED）”）;在此行之后调用Log.d（Constants.DEBUG，“Go to to PROFILE ACTIVITY”）; ...当我将homeFragment作为第一个加载时，Profile Activity立即加载...同样，后退按钮（主页按钮）只是重新加载配置文件活动而不是返回主活动< / p>
