[英]android - FragmentActivity and Navigation Drawer
Problem : When I click an item on the drawer it doesn't show the FragmentActivity that is supposed to be shown. 问题:当我单击抽屉上的某个项目时,它没有显示应该显示的FragmentActivity。 App is ok it doesn't have errors when I compile it and It doesn't crash when I click an item in the drawer
应用程序正常,编译时没有错误,单击抽屉中的项目也不会崩溃
MainActivty 主活动
private void displayView(int position) {
// update the main content by replacing fragments
FragmentActivity fragment = null;
switch (position) {
case 0:
fragment = new HomeFragment();
break;
case 1:
fragment = new LocateFragment();
break;
case 2:
fragment = new SecureFragment();
break;
case 3:
fragment = new NotificationFragment();
break;
default:
break;
}
if (fragment != null) {
LayoutInflater inflater = getLayoutInflater();
LinearLayout container = (LinearLayout)findViewById(R.id.frame_container);
inflater.inflate(R.layout.activity_main,container);
//FragmentManager fragmentManager = getFragmentManager();
//fragmentManager.beginTransaction()
//.replace(R.id.frame_container, fragment).commit();
// update selected item and title, then close the drawer
mDrawerList.setItemChecked(position, true);
mDrawerList.setSelection(position);
setTitle(navMenuTitles[position]);
mDrawerLayout.closeDrawer(mDrawerList);
} else {
// error in creating fragment
Log.e("MainActivity", "Error in creating fragment");
}

I guess you are after something like this. 我想你是在追求这样的事情。 You will with this put the fragment in the container view.
您将以此将片段放入容器视图中。 Hope it helps
希望能帮助到你
