Drawer Toggle indicator "hamburger" doesn't animate until after initial orientation change

I've googled this for quite a while and nothing seems to match my issue. When my app starts the hamburger is fixed (no animation) until I do an orientation change, then it animates in both layouts. I'm using the ActionBarDrawerToggle from the v4 support pack (deprecated, I know). Here's the (fairly standard) code:
public class BaseActivity extends Activity {
private DrawerLayout mDrawerLayout;
private ListView mDrawerList;
private ActionBarDrawerToggle mDrawerToggle;
// nav title
private CharSequence mDrawerTitle;
// used to store app title
private CharSequence mTitle;
// slide menu items
private String[] navMenuTitles;
private TypedArray navMenuIcons;
private ArrayList<NavDrawerItem> navDrawerItems;
private NavDrawerListAdapter adapter;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
requestWindowFeature(Window.FEATURE_INDETERMINATE_PROGRESS);
setContentView(R.layout.base_activity_fragment);
//mTitle = mDrawerTitle = getTitle();
// load slide menu items
navMenuTitles = getResources().getStringArray(R.array.nav_drawer_items);
// nav icons from resources
navMenuIcons = getResources()
.obtainTypedArray(R.array.nav_drawer_icons);
mDrawerLayout = (DrawerLayout) findViewById(R.id.drawer_layout);
mDrawerList = (ListView) findViewById(R.id.list_slidermenu);
navDrawerItems = new ArrayList<NavDrawerItem>();
// Adding nav items to array
navDrawerItems.add(new NavDrawerItem(navMenuTitles[0], navMenuIcons.getResourceId(0, -1)));
navDrawerItems.add(new NavDrawerItem(navMenuTitles[1], navMenuIcons.getResourceId(1, -1)));
navDrawerItems.add(new NavDrawerItem(navMenuTitles[2], navMenuIcons.getResourceId(2, -1)));
navDrawerItems.add(new NavDrawerItem(navMenuTitles[3], navMenuIcons.getResourceId(3, -1)));
navDrawerItems.add(new NavDrawerItem(navMenuTitles[4], navMenuIcons.getResourceId(4, -1)));
// Recycle the typed array
navMenuIcons.recycle();
mDrawerList.setOnItemClickListener(new SlideMenuClickListener());
// setting the nav list adapter
adapter = new NavDrawerListAdapter(getApplicationContext(),
navDrawerItems);
mDrawerList.setAdapter(adapter);
// enabling action bar app icon and behaving it as toggle button

Can anyone see where I've gone wrong and how to get the hamburger to animate all the time? Thanks!

Android navigation drawer baseactivity possible with different items?

I find a lot of tutorials on the Internet on how to implement a navigation drawer for Android Studio.
However, let's say I want to create a navigation drawer for any activity but with different items, is it possible to create some sort of baseactivity so I only need to write the NavDrawerItems and the DrawerItemClickListener ...
Can this BaseActivity be achieved or is it too far fetched? I searched alot on Google about this, but didn't find any tutorials concerning this particular question I got :( Most of the baseactivity tutorials I find are for navigation drawer with the same items.
Edit:
Code I have for now, but in my opinion it's a bit long to read:
Tutorials I used are:

}

In my opinion, it's possible. You can set it when preparing your list data, as the following sample
private static void prepareListData(final Context context) {
final Activity activity = ((Activity) context);
String activity_name = context.getClass().getSimpleName().replace("Activity", "");
sListDataHeader = new ArrayList<>();
sListDataChild = new HashMap<>();
// adding header data, except current activity
String[] mItemHeaders = activity.getResources().getStringArray(R.array.items_array_expandable_header);
// here...
for (String item : mItemHeaders) {
if (!item.toLowerCase().equals(activity_name.toLowerCase())) {
sListDataHeader.add(item);
}
}
String[] mItemMainChild = activity.getResources().getStringArray(R.array.items_array_expandable_main_child);
// Child data
List<String> listChild = Arrays.asList(mItemMainChild);
// Header, Child data
for (int i = 0; i < sListDataHeader.size() - 2; i++) {
sListDataChild.put(sListDataHeader.get(i), new ArrayList<String>());
}
sListDataChild.put(sListDataHeader.get(sListDataHeader.size() - 1), listChild);
}
Hope this help!

ListView content lost after fragment change

I was trying to implement Dynamically updating a list in a ListFragment.
But, when i change my fragment(i.e. from fragment 1 to fragment 2 and back to fragment 1) the list contents are lost.
Below is my ListFragment.
public class FragmentOne extends ListFragment {
String[] order = new String[] {};
public FragmentOne(){}
/** Items entered by the user is stored in this ArrayList variable */
ArrayList<String> list = new ArrayList<String>();
/** Declaring an ArrayAdapter to set items to ListView */
ArrayAdapter<String> adapter;
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
final View rootView = inflater.inflate(R.layout.fragment_1, container, false);
/** Reference to the button of the layout main.xml */
Button btn = (Button) rootView.findViewById(R.id.btnAdd);
/** Defining a click event listener for the button "Add" */
OnClickListener listener = new OnClickListener() {
#Override
public void onClick(View v) {
EditText edit = (EditText) rootView.findViewById(R.id.txtItem);
list.add(edit.getText().toString());
edit.setText("");
adapter.notifyDataSetChanged();
}
};
/** Setting the event listener for the add button */
btn.setOnClickListener(listener);
/** Defining the ArrayAdapter to set items to ListView */
adapter = new ArrayAdapter<String>(getActivity(), android.R.layout.simple_list_item_1, list);
/** Setting the adapter to the ListView */
setListAdapter(adapter);
return rootView;
}}

Thanks in advance

When you go back from Fragment2 to Fragment1, you're creating a new instance of Fragment1. So of course your ListView will be empty (until the user adds items via the button you're supplying).
Maybe you need to modify displayView(int position) so it doesn't create an instance everytime, by null-checking and global vars maybe?

as #lenix mentioned when you come back to fragment1 the displayView does create a new fragment because you say that to the FragmentManager I've created new one and replace it..
In this case you should check isFragment added already? no then add otherwise hide and show fragment..
FragmentTransaction transaction = fragmentManager.beginTransaction();
if(fragment1.isAdded){
transaction.show(fragment1)
}else{
transaction.add(fragment1)
}
dont forget to commit when you done.. and its just way to see you how you can do.. this snippet doesnt work..

Each time you load your fragment, your ArrayList will start off empty. You could save the current list items to shared preferences and have the list fetched each time the fragment is loaded, or implement a set/get callback in your activity.

Android widget, launch a Fragment?

I currentley have an adroid widget, that when clicked on launches an activity. I have changed my whole app to fragments in order to use the android navigation drawer, and I am not sure how to launch my fragment when my widget is clicked.
My widget code which launches an activity is:
public class SearchWidget extends AppWidgetProvider {
public void onUpdate(Context context, AppWidgetManager appWidgetManager, int[] appWidgetIds) {
final int N = appWidgetIds.length;
// Perform this loop procedure for each App Widget that belongs to this provider
for (int i=0; i<N; i++) {
int appWidgetId = appWidgetIds[i];
// Create an Intent to launch ExampleActivity
Intent intent = new Intent(context, Search.class);
PendingIntent pendingIntent = PendingIntent.getActivity(context, 0, intent, 0);
// Get the layout for the App Widget and attach an on-click listener
// to the button
RemoteViews views = new RemoteViews(context.getPackageName(), R.layout.widget_search);
views.setOnClickPendingIntent(R.id.searchclick, pendingIntent);
// Tell the AppWidgetManager to perform an update on the current app widget
appWidgetManager.updateAppWidget(appWidgetId, views);
}
}
}
How can I launch a fragment, but also launch it in my view which hold my drawer also?
I have a MainDrawer activity:

The main drawer uses this xml which has a fragment for the navigation drawer and one for the actual fragments that get loaded. The MainDrawer activity above initiates with the statistics fragment. I want my widget to launch with the below xml but not initiate the statistics fragment. I want it to load another fragments.
XML:

So it looks like you already have a good framework in place that'll make this easy. First, define a value for an extra to pass in with your launch intent:
public class MainDrawer2 extends Activity {
public static final String EXTRA_DEFAULT_FRAGMENT = "my.package.name.EXTRA_DEFAULT_FRAGMENT";
public static final int FRAGMENT_STATISTICS = 0;
public static final int FRAGMENT_DISCOVER = 1;
//... etc.
Then, in your onCreate(), where you current call displayView(0), do something like:
if (savedInstanceState == null) {
Intent i = getIntent();
// Default to the stats fragment if a default wasn't supplied
int defaultView = i.getIntExtra(EXTRA_DEFAULT_FRAGMENT, FRAGMENT_STATISTICS);
displayView(defaultView);
}
This way, you can create your PendingIntent with your Activity launch Intent, but when you do so, simply include the default fragment extra:
Intent i = new Intent(context, MainDrawer2.class);
i.putExtra(MainDrawer2.EXTRA_DEFAULT_FRAGMENT, MainDrawer2.FRAGMENT_DISCOVER);
PendingIntent pi = PendingIntent.getActivity(context, 0, i, 0);

Here's an example of doing what you want.

Android Navigation Drawer BaseActivity sample

Can someone suggest me a tutorial how to create a BaseActivity for the Android Navigation Drawer ?
Or can anyone post a sample BaseActivity for the Navigation Drawer including the layout ?

Download sample Code from Google n i have edited that code as basic navigation drawer with fragment no imageview
public class MainActivity extends Activity {
private DrawerLayout mDrawerLayout;
private ListView mDrawerList;
private ActionBarDrawerToggle mDrawerToggle;
private CharSequence mDrawerTitle;
private CharSequence mTitle;
private String[] mPlanetTitles;

protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.navigation_drawer);
Fragment fragment = new PlanetFragment();
FragmentManager fragmentManager = getFragmentManager();
fragmentManager.beginTransaction().replace(R.id.content_frame, fragment).commit();
// mTitle = mDrawerTitle = getTitle();
// mPlanetTitles = getResources().getStringArray(R.array.planets_array);
// mDrawerLayout = (DrawerLayout) findViewById(R.id.drawer_layout);
//mDrawerList = (ListView) findViewById(R.id.right_drawer);
// set a custom shadow that overlays the main content when the drawer opens
// mDrawerLayout.setDrawerShadow(R.drawable.drawer_shadow, GravityCompat.START);
/* // set up the drawer's list view with items and click listener
// mDrawerList.setAdapter(new ArrayAdapter<String>(this,
R.layout.drawer_list_item, mPlanetTitles));
mDrawerList.setOnItemClickListener(new DrawerItemClickListener());
// enable ActionBar app icon to behave as action to toggle nav drawer
// getActionBar().setDisplayHomeAsUpEnabled(true);
// getActionBar().setHomeButtonEnabled(true);
// ActionBarDrawerToggle ties together the the proper interactions
// between the sliding drawer and the action bar app icon
mDrawerToggle = new ActionBarDrawerToggle(
this, host Activity
mDrawerLayout, DrawerLayout object
R.drawable.ic_drawer, nav drawer image to replace 'Up' caret
R.string.drawer_open, "open drawer" description for accessibility
R.string.drawer_close "close drawer" description for accessibility

You can achieve this with the help of fragments. Go through following which have sample code and video tutorial.
