I wanted to choose the approach using a navigationDrawer in multiple activities using an AbstractActivity which hosts the NavDrawerl layout and initialization and my inherited activities just set there layout as a content of the drawerLayout. Everything works fine, the Drawer is reachable anywhere. A click on one List item should then start a new activity.
I chose to try this because i don't want one single activity which than hosts 10k lines of code implementing all my inter process communication and background service stuff. Everything works fine. except that the Drawer indeed is closed on my new started activity. this isn't nice because normally if you select something from the list it slides back pretty nice. I wanted to find a compromise and just animate the closing in the new activity which wouldn't make much of a difference. but i can not get it to work because all my calls

does anybody have a clue how we could get this to work looking "cool". I think it would be a nice solution for complex apps. I don't like the One Activity 1943209483280 Fragment Action Listener approach.

I'm using NavigationDrawer as the main activity, but when I go to another fragment I want to modify the menu, putting an arrow to back to the home and hide the search icon of the navbar, so I'm having two problems here, I can hide the search icon when I change the fragment, but when I'm back to the navigationMain it should be visible again, which is not happening, and if I am in another fragment the navigation bar must be removed and an arrow back must appear so I can get back to home, this is what I've tried so far:
public class NavigationMain extends ActionBarActivity{
private DrawerLayout mDrawerLayout;
private ListView mDrawerList;
private android.support.v7.app.ActionBarDrawerToggle mDrawerToggle;
private CharSequence mDrawerTitle;
private CharSequence mTitle;
private String[] mPlanetTitles;

mDrawerList.setOnItemClickListener(new DrawerItemClickListener());
mDrawerToggle = new android.support.v7.app.ActionBarDrawerToggle(
this, /* host Activity */
mDrawerLayout, /* DrawerLayout object */
toolbar, /* 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 */

} else {
Toast.makeText(this, R.string.app_not_available, Toast.LENGTH_LONG).show();
}
return true;

}
}
/* The click listner for ListView in the navigation drawer */
private class DrawerItemClickListener implements ListView.OnItemClickListener {
#Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {

private void selectItem(int position) {
FragmentManager fragmentManager = getSupportFragmentManager();
Fragment fragment = new InstituicoesFragment();
switch (position) {

fragmentManager.beginTransaction().replace(R.id.content_frame, fragment).commit();
break;
}
// Load your conten here
Toast.makeText(NavigationMain.this, "Position" + position, Toast.LENGTH_LONG).show();
// update selected item and title, then close the drawer
mDrawerList.setItemChecked(position, true);
mDrawerLayout.closeDrawer(mDrawerList);

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

#Override

super.onBackPressed();
}
}
In my Fragment I add the following:
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setHasOptionsMenu(true);
}
#Override
public void onCreateOptionsMenu(Menu menu, MenuInflater inflater) {
inflater.inflate(R.menu.main, menu);
menu.removeItem(R.id.action_websearch);
super.onCreateOptionsMenu(menu, inflater);
}
i used this method :
i inflate the menu for the actionbar with all the items already in.
then in the Activity onCreateOptionsMenu() i check wich fragment is displayed and i set the visibility of the items accordingly.
then in the onSectionAttached method i call invalidateOptionsMenu(); that will reload the onCreateOptionsMenu so i can have different menu items on each fragment selected
for checking i use boolean flags and if the flag is true it means that the fragment is n view, like:
viewing the first fragment:
ft.replace(R.id.container, firstFragment);
firstfragmentIsOn=true;
secondFragmentIsOn=false;
viewing the second fragment:
ft.replace(R.id.container, secondFragment);
firstfragmentIsOn=false;
secondFragmentIsOn=true;
and in the onCreateOptionsMenu:
MenuItem item1=menu.findItem(R.id.item1);
MenuItem item2=menu.findItem)(R.id.item2);
if(firstfragmentIsOn)
{
item1.setVisible(true);
item2.setVisible(false);
}
if(secondFragmentIsOn)
{
item1.setVisible(false);
item2.setVisible(true);
}
At the moment I have a Base Activity class which implements an action bar across all my activities, I now want to add to this base class so that it implements a navigation drawer. But having a base activity which implements a navigation drawer gives me a lot of conflicting view errors.
My main goal is to have a viewpager activity extend this base activity which implements a navigation drawer, How can I do this? or is there a work around?
Thanks
This is how I am doing this. I don't exactly remember where I took it but it is also changed. In my case I defined it as abstract and extended my MainActivity from this. The reason was to keep the logic related to DrawerActivity in one class so it is not mixed with my business logic.

I was having the same issue and i just fixed it tonight.
I had a view pager/swipe tab setup that i wanted to add a navigation drawer to.
I built my navigation drawer to extend to my view pager according to this tutorial.
when i tried to extend it to my viewpager class i had to remove the "fragmentactivity" extend for "navigator". this gave me the same issue your having now. it took me 3 hours of research to realize that if i extend class A in class B, then as long as class A is "Extending" the same "supporting Class" that Class B needs, then you wont have that null pointer issue.
here the code: navigation_draw.xml

Here is what you will get:
1 is the fragment and 2 is the viewPager
Working from this android example, I've attempted to create an app that uses the support version (android.support.v4 and android.support.v7).
The example creates a menu drawer that looks like this
and my code gets this
Notice the icon is different and the way it moves is different, well in my version it doesn't move.
Example code
public class MainActivity extends Activity {
private DrawerLayout mDrawerLayout;
private ListView mDrawerList;
private ActionBarDrawerToggle mDrawerToggle;
private CharSequence mDrawerTitle;
private CharSequence mTitle;
private String[] mPlanetTitles;
#Override
protected void onCreate(Bundle savedInstanceState) {

mTitle = mDrawerTitle = getTitle();
mPlanetTitles = getResources().getStringArray(R.array.planets_array);

// 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

Does anyone know why its not using my toggle icon or moving? Or is it that you can't do it like that using the support libraries?
I'm still investigating what I missed and will update this answer accordingly. Though as #kaedill mentions it is possible using the support libraries.
Here is a full copy of the Google example, edited by myself to use the support libraries.

I have tested this and it works as it should on a Gingerbread device.
I am going to go through the changes in my app and figure out what I did wrong.
Update
After a painful dissection of my original code, I ported my code into the working example and a diff showed my error.
#Override
protected void onPostCreate(Bundle savedInstanceState) {
super.onPostCreate(savedInstanceState);
// Sync the toggle state after onRestoreInstanceState has occurred.
mDrawerToggle.syncState();
}
My original code had not overridden the onPostCreate method. An annoying little bug to find! Hope it helps someone else out in the future.
You can do it with the support libraries. The only difference I can see from my working version with the ActionbarActivity is a call to super like this:
public void onDrawerClosed(View drawerView)
{
super.onDrawerClosed(drawerView);
getSupportActionBar().setTitle(mTitle);
supportInvalidateOptionsMenu(); // creates call to onPrepareOptionsMenu()
Log("onDrawerOpened()");
}
public void onDrawerOpened(View drawerView) {
super.onDrawerOpened(drawerView);
getSupportActionBar().setTitle(mDrawerTitle);
supportInvalidateOptionsMenu(); // creates call to onPrepareOptionsMenu()
Log("onDrawerOpened()");
}
Did you copy the ic_drawer drawable from the example to your project? I think yes because the code should no compile without that drawable, but when I've implemented DrawerLayout in my app, I had to copy that drawable inside my resources.
I am new in Android world. I have followed this tutorial to create a swipe menu but the items of this menu just show an image. I want to link every single one to a new activity, is this possible?

yes you can do that in onOptionsItemSelected event.
onOptionsItemSelected has a paremeter of type MenuItem . you can see the paremeter here onOptionsItemSelected(MenuItem item).
Just pick item.getTitle and do what you want according to the selected item
Replace OtherActivity.class and anotherActivity.class with your actual activity class names and you are done.
#Override
public boolean onOptionsItemSelected(MenuItem item)
{
if (item.getTitle()=="View 1")
{
Intent newActivity = new Intent(this,OtherActivity.class );
startActivity(newActivity);
}
else
{
Intent newActivity = new Intent(this,anotherActivity.class);
startActivity(newActivity);
}
return MenuChoice(item);
}
I have one problem, how to implement a merchandising display before starting my navigation drawer. this is my code. Thanks for help guys.
This is my code merchan, but is wrong, I want to call this screen before the application itself, which is basically a navigation drawer.
public class Merchan extends Activity {
#Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
setContentView(R.layout.merchan);
Thread logoTimer = new Thread() {
public void run() {
try {
sleep(3000);
Intent menuIntent = new Intent("com.codehevea.menu.Main");
startActivity(menuIntent);
} catch (InterruptedException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} finally {
finish();
}
}
};
logoTimer.start();
}
#Override
protected void onPause() {
// TODO Auto-generated method stub
super.onPause();
}
}
And this is my principal class. It should boot screen after merchandising.

You're using the wrong Intent constructor. Change it to something like:
Intent menuIntent = new Intent(this, com.codehevea.menu.Main.class);
Note, if the current and target class are in the same package, you don't need the package name, so:
Intent menuIntent = new Intent(this, Main.class);
