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:

super.onConfigurationChanged(newConfig);
// Pass any configuration change to the drawer toggls
mDrawerToggle.onConfigurationChanged(newConfig);
}
}

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!

You have to create handler in Activity
just initialize the Handler in onCreate method of activity
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
progressBarHandler = new Handler();
// rest of your code
and remove the initialization in Fragment class as it is already initialized in Activity . Just Use progressBarHandler in Fragment Class and it will work fine.

Fragment called twice [duplicate]

This question already has an answer here:
Fragments starting twice
(1 answer)
Closed 8 years ago.
I'm trying to start a fragment from an activity, but everytime I start the app, the fragment is started twice. This is only happening when I run the app on a tablet device.
Does anyone know what can this issue be, and how can I solve it?
Here is my code:
public class TestSearch extends FragmentActivity {

I'm guessing that onCreate() is called twice, and the function showMainFragment(); is called twice.

When you're starting your Activity you're calling:
setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE);
When calling this method, your Activity is possibly restarted, if the tablet is in portrait mode when the app starts up. This is stated in the documentation.
When you're Activity is restarted, onCreate is called once again and your Fragment is created once again.
On a side-note: It's not good practice to force your app into a specific orientation.

How can I call one of my activity using navigation drawer ?

I have my navigation drawer activity as my MainActivity class and I already have Homepage.class activity previously made. Since Navigation Drawer uses Fragments, I am unable to call Homepage class through Drawer. Plz help me.
Here is my code for the Drawer-

XML for the drawer:
<android.support.v4.widget.DrawerLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/drawer_layout"
android:layout_width="match_parent"
android:layout_height="match_parent" >
<!-- Framelayout to display Fragments -->
<FrameLayout
android:id="#+id/frame_container"
android:layout_width="match_parent"
android:layout_height="match_parent">
</FrameLayout>
<!-- Listview to display slider menu -->
<ListView
android:id="#+id/list_slidermenu"
android:layout_width="240dp"
android:layout_height="match_parent"
android:layout_gravity="start"
android:background="#color/list_background"
android:choiceMode="singleChoice"
android:divider="#color/list_divider"
android:dividerHeight="1dp"
android:listSelector="#drawable/list_selector" />
</android.support.v4.widget.DrawerLayout>
And Finally XML for the activity which I want to be called -
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent">
<ListView
android:id="#+id/list"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:divider="#null" />
</LinearLayout>

The API for starting an Activity does not change when using a navigation drawer. You still only need to call startActivity() to launch a different Activity.
In this case, your code will look something like this:
private void displayView(int position) {
// update the main content by replacing fragments
Fragment fragment = null;
switch (position) {
case 0: // Or whatever nav item position should start the Activity
startActivity(new Intent(this, HomePage.class));
return;
// The rest of your cases
}
Note that when after calling startActivity() for the homepage item, we return instead of break so that your displayView() doesn't try to replace the displayed Fragment.

Android ActionBarCompat - Navigation Drawer with multiple fragments

Im new to the ActionBarCompat library.I want to develop an app which contains multiple fragments. Here is what i want to do
1.How to open a fragment when user select that from Navigation Drawer.
2.How to set a startup fragment which displays startup layout (example- In Google plus app,first its displays news feeds.when we select profile item from the side menu,then its hide the side menu/Navigation drawer and displays the profile layout)
Currently i have side menu and one fragment.
Here is the tutorial that i used to follow- wptrafficanalyzer

If you are going to use a slide out menu I recommend you use this slidemenu library I use it in my applications and it allows you to place whatever you want in the slide out menu, the menu is just a frame layout and you can put whatever you want in it (Listview, GridView, or even just a picture)

I am assuming by side menu you meant Navigation Drawer. You can find an answer in the below link.
Navigation Drawer with backword compatibility android
Do read
http://developer.android.com/design/patterns/navigation-drawer.html
Fragment is hosted by a Activity. So you need a container in the activity layout.
<android.support.v4.widget.DrawerLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/drawer_layout"
android:layout_width="match_parent"
android:layout_height="match_parent">
<FrameLayout // container to which you add or replace fragments
android:id="#+id/content_frame"
android:layout_width="match_parent"
android:layout_height="match_parent"/>
<ListView
android:layout_width="240dp"
android:layout_height="match_parent"
android:layout_gravity="start"
android:background="#111"
android:choiceMode="singleChoice"
android:divider="#android:color/transparent"
android:dividerHeight="0dp"/>
</android.support.v4.widget.DrawerLayout>
Initially you don't click any item. So initially add fragment1 to the container.
FragmentTransaction fragTran = getSupportFragmentManager()
.beginTransaction();
Fragment fragment1= new Fragment1();
fragTran.add(R.id.content_frame, fragment1);
fragTran.commit();
On click of listitem based on the position
FragmentTransaction fragTran = getSupportFragmentManager()
.beginTransaction();
Fragment fragment3= new Fragment3();
fragTran.replace(R.id.content_frame, fragment3);
fragTran.commit();

Hi check this code
public class MainActivity extends ActionBarActivity implements

finish();
}
ArrayAdapter<String> al = new ArrayAdapter<String>(

slider_list.setAdapter(al);

// options_drawer.setDrawerListener(toggler);
if (savedInstanceState == null) {

fragmentTransition(f);
}
}
#Override

// Otherwise, setup the chat session

}
#Override

}
And XML file is
