How do I add NavigationDrawer from an activity template to other activities?

I've been playing around with the Drawer Menu activity template from Android Studio since I haven't used a drawer menu before. Here's the layout file.
<android.support.v4.widget.DrawerLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools" android:id="#+id/drawer_layout"
android:layout_width="match_parent" android:layout_height="match_parent"
android:fitsSystemWindows="true" tools:openDrawer="start">
<!-- Includes a Toolbar and FloatingActionButton. Generated by Android Studio-->
<include layout="#layout/app_bar_drawer_menu" android:layout_width="match_parent"
android:layout_height="match_parent" />
<android.support.design.widget.NavigationView android:id="#+id/nav_view"
android:layout_width="wrap_content" android:layout_height="match_parent"
android:layout_gravity="start" android:fitsSystemWindows="true"
app:headerLayout="#layout/nav_header_drawer_menu"
app:menu="#menu/activity_side_menu_drawer" />
</android.support.v4.widget.DrawerLayout>
Android Studio also generated an Activity class as part of the template. My app has a main activity as well that uses a LinearLayout. I want to use Fragments to add the drawer menu to the main activity (and other activities), but I'm unsure how to do this. Do I need to create a new subclass of fragment and adapt DrawerMenuActivity's callback methods for the fragment class? Then do I add a fragment tag to activity_main.xml?

This will likely be something you need to wrap your head around...
Ideally, you want to swap fragments in a container located in the the xml for the MainActivity by using fragment transaction and calling replace with the fragment to be placed in the container. This will allow you to re-use the container and offer the drawer to the entire app.
Otherwise, you would need to include the drawer in every activity which creates a lot of extra code or not offer the drawer which depending on the activity you may be able to get away with that.
So, the drawer works with fragments being swapped in via the transaction and not so well for additional activities. Its something you need to design around.
Please, create a new project with a generated drawer for an Activity and proceed from there. Also read the android developer tutorial for fragments part on communication to see how the drawer fragment and activity communicate.
There's actually quite a bit involved for the drawer but you should be able to get a good grasp in a day or two.

How can I use Fragments to open items on a Drawerlayout, when i used the Activity Drawer Navigation Template that provides android studio?

Template that provide Android Studio
This is how I try to do. What is the R.id.x?. I tried using layout id in xml ActivityMain but not the fragment is displayed or overlaid with out activity information.
After selecting one of the items, the fragment will be displayed above the activity. The activity has several elements belonging to material design as the FAB or the Toolbar, Could this create problems with what I do?

In activity_main.xml try replacing:
<include
layout="#layout/app_bar_main"
android:layout_width="match_parent"
android:layout_height="match_parent"/>
With this:
<FrameLayout android:id="#+id/fragment_container"
android:layout_width="match_parent"
android:layout_height="match_parent" />
And then use R.id.fragment_container as your R.id.x.
This will however replace the view with the FAB and coordinator layout. But you will probably want to add them to the fragments where you want them.
If not you could try replacing the xml found below in app_bar_main.xml, or wrap it in the FrameLayout.
<include layout="#layout/content_main"/>
Update:
Replacing in activity_main.xml will cause some issues as that removes the toolbar.
If you replace the include in app_bar_main.xml your fragments will most likely get overlapped by the toolbar at the top. To prevent this you could try adding app:layout_behavior="#string/appbar_scrolling_view_behavior" in the FrameLayout snippet above.

R.id.x is the id of the View that your fragment going to be replaced. So in your layout R.layout.xyz you have created a layout
<FrameLayout android:id="#+id/fragment_container"
android:layout_width="match_parent"
android:layout_height="match_parent" />
and add/replace the fragment to that id. (R.id.fragment_container) such that your new fragment will be placed in that layout.
transaction.add(R.id.fragment_container, firstFragment)

At the end solved the problem using some of the recommendations made in the answers they provided me.
Change content_main.xml content. Using a FrameLayout with its correspodiente id.
Add fragment on onNavigationItemSelected(MenuItem item)
Result
When I press a menu item ...
...the fragment is displayed

Action Bar Tabs using ViewPager with Navigation Drawer

Requirement:- Action Bar Tabs using ViewPager with Navigation Drawer .
I can create a Navigation Drawer example
Action Bar Tabs using ViewPager separately.
But when I try to use both at once I am having issue.
I can create Navigation Drawer using fragments and Action Bar Tabs using Fragment. But the initial Activity of the both examples is Fragment Activity.
How to implement the action bar tabs on a fragment which is part of the navigation drawer?

The problem of using the tabs of the actionbar is when the drawer appears, it will appears under the tabs, since the tabs are part of the actionBar.
I have tried using tabHost instead and it works much better.
You get the source code here:
https://github.com/jiahaoliuliu/DrawerWithTabsAndViewPager
Here is a little explanation about it:
The first level there is a Drawer, from the v4 support library
Inside the drawer, the first element is the tabHost, which I have set the width and the height of the content to 0.
Under the tabhost, there is the viewpager.
Once everything has been created, what I have done is create a listener for the tabhost and another one for the viewPager, so when the user click on any tab the view pager will set the current item, and viceversa.
Enjoy Coding!

Use the following layout for your main activity.
<?xml version="1.0" encoding="utf-8"?>
<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" >
<android.support.v4.view.ViewPager
android:id="#+id/viewpager_container"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:background="#ffe6e1d4"
android:focusable="true"
android:focusableInTouchMode="true" />
<ListView
android:id="#+id/left_drawer"
android:layout_width="240dp"
android:layout_height="match_parent"
android:layout_gravity="left"
android:listSelector="#drawable/drawer_list_selector"
android:background="#color/drawer_bg" />
</android.support.v4.widget.DrawerLayout>
Write your FragmentPagerAdapter as show in APPTabsAdapter.
This is how I had built it in one of my projects.
You can try and ask for help, if needed.
OR
You can take help from this GitHub Repo.
Thanks.

As you have noticed, ActionBar tabs don't play very nicely with Navigation Drawer and this design mode has been deprecated in API 21 anyway.
I used the classes in SlidingTabs example from Android developers to achieve this effect without having to include a 3rd party library dependency, and am very happy with the result. There is a video tutorial as well.

Android Fragment for tablets and phone

I want to do something like that. An picture is easier than words:
And when the user clicks on a button on the Fragment B, the fragment B changed but not the A.
I've made two different layout (A portrait and a land one). The first one has a layout like
<?xml version="1.0" encoding="utf-8"?>
<fragment
xmlns:android="http://schemas.android.com/apk/res/android"
android:name="com.my.app.ContactsFragment"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:id="#+id/contacts_fragment" />
I've a button in my fragment layout with a simple activity call:
Intent intent = new Intent(getActivity(), NextActivity.class);
startActivity(intent);
And the land one is like that:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="horizontal"
android:layout_width="match_parent"
android:layout_height="match_parent">
<fragment
xmlns:android="http://schemas.android.com/apk/res/android"
android:name="com.my.app.ContactsFragment"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:id="#+id/contacts_fragment" />
<fragment
xmlns:android="http://schemas.android.com/apk/res/android"
android:name="com.my.app.HomeFragment"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:id="#+id/fragment_container" />
</LinearLayout>
I change the inner fragment using the following code:
FragmentTransaction ft = getActivity().getFragmentManager().beginTransaction();
NextFragment nextFrag = new NextFragment();
ft.replace(R.id.fragment_container, nextFrag);
ft.addToBackStack(null);
ft.commit();
This part works well.
I have two questions now:
How to put these two ways to change the content in the main activity? I mean, in the main activity, a fragment should call the second way, but in a normal activity, I need to call the first.
If I click on an item in the fragment A, and then I click on the button in fragment B that changes the fragment to NextFragment. If I click on another item and i do the same. I can go back to the first user. Is there a way to dump the stack when clicking on a new item ?
Thanks for your help.
Ps: I'm using the native fragment lib not the support v4.

I'm struggling to understand the specifics of your 2 questions, as they are vague and do not give enough detail.
However, since you want your Fragments to be changed out at runtime, you should not put <fragment/> in your layout files. Your current architecture makes it impossible to change out the Fragments in your layouts, which is not what you want.
Note: When you add a fragment to an activity layout by defining the fragment in the layout XML file, you cannot remove the fragment at runtime. If you plan to swap your fragments in and out during user interaction, you must add the fragment to the activity when the activity first starts.
You should be using FrameLayout containers for your Fragments in your layout files, and have a single Activity add Fragments to those FrameLayout containers depending on if they are there. This will allow the app to create 1 Fragment in portrait and 2 Fragments in landscape (given you have have a layout for each orientation). This will also allow you to be able to swap out Fragments as your please, and add them to the back stack.
And example of this Google recommended approach can be found here.

You can find a good solution from here.

Android Fragment Not Replacing Properly

I am trying to build an app for 3.0 using fragments. On the left side of the application there is a static fragment, and on the right side there is a dynamic one. Each of my fragments in the dynamic portion have a title. Whenever I go to replace the initial fragment, The title of the first is still shown above the title of the first. Successive replacements replace the lower portion but the initial title is still shown (sorry I cannot post images yet).
Best I can do for image:
Initial Header
New Header
Content(displays fine)
main.xml:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="horizontal" >
<fragment
android:id="#+id/static_fragment"
android:name="ruleout.android.History_Fragment"
android:layout_width="500dp"
android:layout_height="match_parent" />
<fragment
android:id="#+id/dynamic_fragment"
android:name="ruleout.android.New_Screen_Fragment"
android:layout_width="fill_parent"
android:layout_height="match_parent" />
</LinearLayout>
Partial MainActivity used to change fragments
private void open(Fragment toShow)
{
FragmentTransaction fragmentTransaction = FragMag.beginTransaction();
fragmentTransaction.replace(R.id.dynamic_fragment, toShow);
fragmentTransaction.addToBackStack(null);
fragmentTransaction.commit();
}
Please let me know if you need any additional information and thanks in advance for your help.

If you want to dynamically change fragments, you can't declare them in your layout. The Fragment documentation has an example of doing just what I think you are describing, where a layout has a static fragment declared in it along with a FrameLayout for holding a Fragment that will be dynamically added and replaced.
