I'm fairly new to Android programming, but have been doing pretty well until now. I've read a lot of answers to this question but can't seem to make mine work. Basically what I have is a MainActivity with a Navigation Drawer. I have two fragments correctly initialized with corresponding fragment layout xmls. Currently I can get my first fragment to show up when the app starts and when I click on each item in the drawer, the titles change; however, the fragment stays the same. Any suggestions? What I believe to be relevant code is below (not shown is the code for the NavigationDrawerFragment.java with the necessary code automatically built by Eclipse). Thanks in advance!
public class MainActivity extends Activity
implements NavigationDrawerFragment.NavigationDrawerCallbacks {
/**

mTitle = getTitle();
// Set up the drawer.
mNavigationDrawerFragment.setUp(
R.id.navigation_drawer,
(DrawerLayout) findViewById(R.id.drawer_layout));

I was working with the Navigation Drawer based on what Eclipse generated as well (yours looks like it was made with it as well), and I've pruned it a bit so that it's not perfectly silly. I also did some black magic at some points, because I was getting silly errors that I've fixed over times (such as being unable to update the action bar title on Back press, or that if you rotate the screen then the element at index 0 is recreated by the activity):
NavigationDrawerActivity:

An example fragment that is created by this navigation drawer:

private Button btn2;
public MyFragment()
{
super();
titleId = R.string.drawer_myfragment_title;

{
View rootView = inflater.inflate(R.layout.fragment_myfragment, container, false);
return rootView;
}
#Override
public void onViewCreated(View view, Bundle savedInstanceState)
{
super.onViewCreated(view, savedInstanceState);
btn0 = (Button) view.findViewById(R.id.btn0);
btn1 = (Button) view.findViewById(R.id.btn1);
btn2 = (Button) view.findViewById(R.id.btn2);
btn0.setOnClickListener(this);
btn1.setOnClickListener(this);
btn2.setOnClickListener(this);
}
#Override
public void onClick(View v)
{
if (btn0 == v)
{
}
else if (btn1 == v)
{
}
else if (btn2 == v)
{
}
}
}
I hope that works as you intended. I had to do magic with the BackStackListener and stuff to work properly.
I know this is quite old, but I would like to share some articles Ive written about the Application Drawer and Fragment navigation. They are up to date with the latest samples (as for 2017 at least). Feel free to take a look at:

This is kind of hard to explain so I took screenshots of my problem.
So this is my MainActivity.java
I open the navigation drawer and click on Milestones which will bring me to Milestones.java
Here I am at Milestones.java fragment...
working fine for now...
Just how I want it to look.
But when we leave Milestones and go anywhere else and come back it will be messed up. So I will go to Kick Counter.
Here I am in my KickCounter.java fragment
Open navigation drawer and going back to Milestones...
So right now I have fragment Months0Through6 open with Milestones fragment. Some times Months0Through6 and Month12Plus fragments does not show up right away after coming back some times it does. What is always messed up at this point is the Months6Through12 fragment will never display again unless you restart the app. Also swapping between the three fragments is laggy after coming back but never on first view.
Here it is. Where did it go?

I got my code from this youtube video which is almost exactly identical but his MainActivity (which I made into my Milestones fragment) is an activity whereas I used a fragment so I was thinking that might have something to do with my problem.

In Fragments you need to use getChildFragmentManager(), You are using same Fragment manager in the fragments as in Activity. Hope this will help
I am creating an app with a slider and it was working fine and then I added another view and implemented an OnClickListener() for the newly added Views after that I am getting the following error when I open my app

Can someone see where I am going wrong? Thanks in advance..
DrawerItemHolder class should be public, or at least it should not be private.
I have a question about the navigation drawer fragment. As you know this navigation drawer has multiple sections. Let's say 3 sections (Home, Profile, Log out). My intent is when the user click on Log out, the navigation drawer will refresh itself to (Home, Log in).
I was trying to play with code but I couldn't figured it out..
The files that I have are:
MainActivity.java
public class MainActivity extends ActionBarActivity
implements NavigationDrawerFragment.NavigationDrawerCallbacks {
/**
* Fragment managing the behaviors, interactions and presentation of the navigation drawer.
*/
private NavigationDrawerFragment mNavigationDrawerFragment;

setContentView(R.layout.activity_main);
mNavigationDrawerFragment = (NavigationDrawerFragment)
getSupportFragmentManager().findFragmentById(R.id.navigation_drawer);
mTitle = getTitle();
// Set up the drawer.
mNavigationDrawerFragment.setUp(
R.id.navigation_drawer,
(DrawerLayout) findViewById(R.id.drawer_layout));
}
#Override
public void onNavigationDrawerItemSelected(int position) {
android.support.v4.app.Fragment objFragment = null;
if(!GlobalVars.is_logged_in)
{
//if the user is NOT logged in
switch (position){
case 0:
objFragment = new Home();
break;
case 1:
objFragment = new LoginActivity();
break;
}
}
else
{
//if the user is logged in
switch (position){
case 0:
objFragment = new Home();
break;
case 1:
objFragment = new Profile();
break;
case 2:
objFragment = new Logout();
GlobalVars.is_logged_in = false;
mNavigationDrawerFragment.onCreateView(this.getLayoutInflater(), null, null);
break;
}
}
// update the main content by replacing fragments
FragmentManager fragmentManager = getSupportFragmentManager();
fragmentManager.beginTransaction().replace(R.id.container, objFragment).commit();
}

case 2:

}

}

As you can notice the static variable is_logged_in which is a way to tell me if the user clicked on Log out or not.
I also updated the file NavigationDrawerFragment.java that Android studio created for me at the beginning step when it asked me to choose the type of activity and obviously I did not choose a blank one, I chose the Slide menu one that created this Navigation Drawer Fragment
So the code in NavigationDrawerFragment.java is
public class NavigationDrawerFragment extends Fragment {
/**

private static final String STATE_SELECTED_POSITION = "selected_navigation_drawer_position";
/**

* expands it. This shared preference tracks this.
*/
private static final String PREF_USER_LEARNED_DRAWER = "navigation_drawer_learned";
/**
* A pointer to the current callbacks instance (the Activity).
*/
private NavigationDrawerCallbacks mCallbacks;
/**

Any help will be great from you guys...
What I would try is taking the code you use to set the adapter, and putting it into its own method like this:
private void setupListView(){
if(!GlobalVars.is_logged_in)
{
//the user is NOT logged in
mDrawerListView.setAdapter(new ArrayAdapter<String>(
getActionBar().getThemedContext(),
android.R.layout.simple_list_item_activated_1,
android.R.id.text1,
new String[]{
//section1: home section2: profile section3:login
getString(R.string.title_section1),
getString(R.string.title_section3),
}));
}
else
{
//the user is logged in
mDrawerListView.setAdapter(new ArrayAdapter<String>(
getActionBar().getThemedContext(),
android.R.layout.simple_list_item_activated_1,
android.R.id.text1,
new String[]{
//section1: home section2: profile section3:login
getString(R.string.title_section1),
getString(R.string.title_section2),
"Log out",
}));
}
}
Then, inside onCreateView(), replace all that code with the line setupListView(), and then also in the onClickListener for the listview you can check if they clicked logout/logon, and after you change the global variable you can call setupListView() again.
Alright, Thank you so much guys but I solved this issue by calling the part that is responsible for drawing the side menu bar in the MainAvtivity.java like the following
case 2:
objFragment = new Logout();
GlobalVars.is_logged_in = false;
mNavigationDrawerFragment.setupListView();
//mNavigationDrawerFragment.onCreateView(this.getLayoutInflater(), null, null);
break;
so each time the user click on the Log out it will execute the drawing function
Special thanks to #McAdam331
You can just call your item from navigationView object.
navigationView.getMenu().findItem(R.id.navigation_item_2).setTitle("Hello");
I am beginner in android and trying to link one tile of sliding drawer to map activity extended as fragment.
I tried it by creating a new Intent and starting it,but it is starting it as new activity and not in the drawer.
Any help is appreciated.

And here is where i set the new layout at the onCreateView:
public class Events extends Activity

}
#Override
public void onNavigationDrawerItemSelected(int position) {
// update the main content by replacing fragments
FragmentManager fragmentManager = getFragmentManager();
fragmentManager.beginTransaction()
.replace(R.id.container, PlaceholderFragment.newInstance(position + 1))
.commit();
}
public void onSectionAttached(int number) {
switch (number) {
case 1:
mTitle = getString(R.string.title_section1);
break;
case 2:
mTitle = getString(R.string.title_section2);
break;
}
}
public void restoreActionBar() {
ActionBar actionBar = getActionBar();
actionBar.setNavigationMode(ActionBar.NAVIGATION_MODE_STANDARD);
actionBar.setDisplayShowTitleEnabled(true);
actionBar.setTitle(mTitle);
}
#Override

if (!mNavigationDrawerFragment.isDrawerOpen()) {
// Only show items in the action bar relevant to this screen
// if the drawer is not showing. Otherwise, let the drawer

restoreActionBar();
return true;
}
return super.onCreateOptionsMenu(menu);
}

return super.onOptionsItemSelected(item);
}

return null;
}

}
Found the answer, had to change onNavigationDrawerItemSelected from:
#Override
public void onNavigationDrawerItemSelected(int position) {
// update the main content by replacing fragments
FragmentManager fragmentManager = getFragmentManager();
fragmentManager.beginTransaction()
.replace(R.id.container, PlaceholderFragment.newInstance(position + 1))
.commit();
}
TO:
#Override
public void onNavigationDrawerItemSelected(int position) {
// update the main content by replacing fragments
switch(position)
{
case 0:
// FragmentCalendar
// use fragment transaction and add the fragment to the container
FragmentManager fragmentManager = getFragmentManager();
android.app.FragmentTransaction fragmentTransaction = fragmentManager.beginTransaction();
FragmentCalendar fragment = new FragmentCalendar();
fragmentTransaction.replace(R.id.container, fragment);
fragmentTransaction.commit();
break;
case 1:
// FragmentAddEvent
FragmentManager frag = getFragmentManager();
android.app.FragmentTransaction trans = frag.beginTransaction();
FragmentAddEvent fragment2 = new FragmentAddEvent();
trans.replace(R.id.container, fragment2);
trans.commit();
break;
}
}
Had the use the static class fragment in the java file from every layout
