How can I implement my custom toolbar in my Fragment

I read so much article and watched so many videos but I still don't know, how to set up an action bar in an Fragment. I have a activity X with an custom toolbar and one navigation view on the top left(the toolbar is separated in an xml file), I import it in the xml for the activity X.
Here is my toolbar in one single xml:
<?xml version="1.0" encoding="utf-8"?>

toggle.syncState();
}
#Override
public boolean onNavigationItemSelected(#NonNull MenuItem item) {

}
#Override
public void onBackPressed() {
if (drawer.isDrawerOpen(GravityCompat.START)) {
drawer.closeDrawer(GravityCompat.START);
} else {
super.onBackPressed();
}
}
}
EDIT, new activity X ( look at my comment "Toolbar_chooser or toolbar"):
public class ChoosingActivity extends AppCompatActivity implements NavigationView.OnNavigationItemSelectedListener {
private DrawerLayout drawer;

Toolbar toolbar = findViewById(R.id.toolbar_chooser); // Toolbar_chooser or toolbar?
setSupportActionBar(toolbar);
drawer = findViewById(R.id.drawerChooser);
NavigationView navigationView = findViewById(R.id.nav_view);
navigationView.setNavigationItemSelectedListener(this);
ActionBarDrawerToggle toggle = new ActionBarDrawerToggle(this, drawer, toolbar,
R.string.navigation_drawer_open, R.string.navigation_drawer_close);
drawer.addDrawerListener(toggle);
toggle.syncState();
}
#Override
public boolean onNavigationItemSelected(#NonNull MenuItem item) {
// Item will be Selected
switch (item.getItemId()) {
case R.id.nav_meetings:

}
#Override
public void onBackPressed() {
if (drawer.isDrawerOpen(GravityCompat.START)) {
drawer.closeDrawer(GravityCompat.START);
} else {
super.onBackPressed();
}
}
}
And here my Fragment where I want to add the toolbar with the navigation view:
import android.os.Bundle;
import android.support.annotation.NonNull;
import android.support.annotation.Nullable;
import android.support.design.widget.NavigationView;
import android.support.v4.app.Fragment;
import android.support.v4.view.GravityCompat;
import android.support.v4.widget.DrawerLayout;
import android.support.v7.app.ActionBar;
import android.support.v7.app.ActionBarDrawerToggle;
import android.support.v7.app.AppCompatActivity;
import android.support.v7.widget.Toolbar;
import android.view.LayoutInflater;
import android.view.Menu;
import android.view.MenuInflater;
import android.view.MenuItem;
import android.view.View;
import android.view.ViewGroup;
public class Ausstehende_Treffen_Fragment extends Fragment {
#Nullable
#Override
public View onCreateView(#NonNull LayoutInflater inflater, #Nullable ViewGroup container, #Nullable Bundle savedInstanceState) {
return inflater.inflate(R.layout.fragment_ausstehende_treffen,container,false);
}
#Override
public void onViewCreated(#NonNull View view, #Nullable Bundle savedInstanceState) {
Toolbar toolbar = (Toolbar) view.findViewById(R.id.toolbar);
((AppCompatActivity)getActivity()).getSupportActionBar(toolbar); // HOW???
}
}
EDIT, new Fragment:
public class Ausstehende_Treffen_Fragment extends Fragment {
// Toolbar toolbar = (Toolbar) getActivity().findViewById(R.id.toolbarreal);
#Nullable
#Override
public View onCreateView(#NonNull LayoutInflater inflater, #Nullable ViewGroup container, #Nullable Bundle savedInstanceState) {
return inflater.inflate(R.layout.fragment_ausstehende_treffen,container,false);
}
#Override
public void onViewCreated(#NonNull View view, #Nullable Bundle savedInstanceState) {
Toolbar toolbar = ((ChoosingActivity)getActivity()).findViewById(R.id.toolbar_ausstehende_treffen);
}
}
Here is also my xml for the fragment, where I want to have the toolbar:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#android:color/holo_orange_light">
<include
android:id="#+id/toolbar_ausstehende_treffen"
layout= "#layout/toolbar"/>
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Ausstehende Treffen Fragment"
android:textSize="25sp"
android:layout_centerInParent="true"/>
</RelativeLayout>
Im not able anymore to open my navigation bar in my choosing activity and I don't know why..
I include the toolbars manually in the xml files, its necessary right? + some code in the fragment itself. Man I hope you understand my code and my problems. Pls help me I just want to keep my custom toolbar in any fragment and activity.
Pls help me, its so frustrating, waste so many hours for just a toolbar, which already exists..

Try adding toolbar in you activity :
mTopToolbar = (Toolbar) findViewById(R.id.my_toolbar);
setSupportActionBar(mTopToolbar);
Get the Activity that owns the fragment (Fragment.getActivity()) and set its ActionBar property.
Then juse use the same setDisplayHomeAsUpEnabled method you mentioned to begin with on the ActionBar after setting your toolbar as the ActionBar to get the back / up button.
sample to access it from fragment :
((AppCompatActivity)getActivity()).getSupportActionBar().setSubtitle();
Hope it helps.

As simple as this.
Toolbar toolbar = ((ChoosingActivity)getActivity()).findViewById(R.id.toolbar);
Now do whatever you want to do man ;).

It's probably because your Toolbar is covered by everything else in DrawerLayout. Try swapping LinearLayout and DrawerLayout, so that the vertical LinearLayout is your root layout, something like this:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="match_parent"
xmlns:tools="http://schemas.android.com/tools"
android:orientation="vertical">
<android.support.v7.widget.Toolbar
android:id="#+id/toolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
android:background="#color/colorPrimary"
android:elevation="4dp"
android:theme="#style/ThemeOverlay.AppCompat.Dark.ActionBar"
app:popupTheme="#style/ThemeOverlay.AppCompat.Light" />
<android.support.v4.widget.DrawerLayout
android:id="#+id/drawerChooser"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#drawable/new_gradients"
android:fitsSystemWindows="true"
tools:context=".ChoosingActivity">
<FrameLayout
android:id="#+id/fragment_container_toolbar"
android:layout_width="match_parent"
android:layout_height="match_parent" />
</android.support.v4.widget.DrawerLayout>
<android.support.design.widget.NavigationView
android:id="#+id/nav_view"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:layout_gravity="start"
app:headerLayout="#layout/header"
app:menu="#menu/drawer_menu">
</android.support.design.widget.NavigationView>
</LinearLayout>
Something approximately like that, the key is that your Toolbar has to be outside your DrawerLayout.

How to force the buttons in bottom navigation to be at the bottom in android studio

I am trying to use bottom navigation but the buttons or icons appears in the middle not in the bottom, I have use drawer navigation in the same activity i.e. I declare a drawer layout in the xml resource layout.
?xml version="1.0" encoding="utf-8"?>
<android.support.v4.widget.DrawerLayout xmlns:android="http://schemas.android.com/apk/res/android"

android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context=".MainActivity">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent">
<TextView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:text="Hello"/>
</LinearLayout>
<android.support.design.widget.BottomNavigationView
android:id="#+id/navigation"
android:layout_width="168dp"
android:layout_height="168dp"
android:background="?android:attr/windowBackground"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintLeft_toLeftOf="parent"
app:layout_constraintRight_toRightOf="parent"
app:menu="#menu/navigation" />
<android.support.design.widget.NavigationView
android:layout_width="match_parent"
android:layout_height="match_parent"
app:menu="#menu/drawer"
android:layout_gravity="start">
</android.support.design.widget.NavigationView>
The code of this activity:
package com.example.welcome.madrasti;
import android.content.ClipData;
import android.content.Intent;
import android.os.Bundle;
import android.support.annotation.NonNull;
import android.support.design.widget.BottomNavigationView;
import android.support.v4.widget.DrawerLayout;
import android.support.v7.app.ActionBarDrawerToggle;
import android.support.v7.app.AppCompatActivity;
import android.view.MenuItem;
import android.widget.TextView;
public class MainActivity extends AppCompatActivity {
private TextView mTextMessage;
Intent intent1;
private DrawerLayout d;
private ActionBarDrawerToggle a;
private BottomNavigationView.OnNavigationItemSelectedListener mOnNavigationItemSelectedListener
= new BottomNavigationView.OnNavigationItemSelectedListener() {
#Override
public boolean onNavigationItemSelected(#NonNull MenuItem item) {
switch (item.getItemId()) {
case R.id.navigation_dashboard:
return true;
case R.id.navigation_home:
return true;
}
return false;
}
};
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
d = (DrawerLayout) findViewById(R.id.container);
a= new ActionBarDrawerToggle(MainActivity.this,d,R.string.open,R.string.close);
d.addDrawerListener(a);
a.syncState();
getSupportActionBar().setDisplayHomeAsUpEnabled(true);
intent1= new Intent(getApplicationContext(),MapsActivity.class);
BottomNavigationView navigation = (BottomNavigationView) findViewById(R.id.navigation);
navigation.setOnNavigationItemSelectedListener(mOnNavigationItemSelectedListener);
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
if(a.onOptionsItemSelected(item)){
return true;
}
return super.onOptionsItemSelected(item);
}
}
Is there any idea ?. I have got the bottom navigation as follows : here

Changing padding at the Bottom to small a value like:
android:paddingBottom="2dp"
Also your BottomNavigationView appears to be a square of 168dp size. Is this intentionally? Change the height it or view its layout bounds. It may be very big by itself like a square.

There may be few reasons of NullPointException, try to:
You are probably using a Theme that doesn't support ActionBar.
Trying using this theme:
android:theme="#android:style/Theme.Holo.Light".
try to catch:
if (getSupportActionBar() != null)
{
getSupportActionBar().setDisplayHomeAsUpEnabled(true);
getSupportActionBar().setHomeButtonEnabled(true);
}
Or, try to change the id of app_bar in aap.java

findViewById method returning null.
Add id attribute to your toolbar
android:id="#+id/aap_bar
You are also using wrong namespace aap
Use app
xmlns:app="http://schemas.android.com/apk/res-auto"

Adding Tablayout and Toolbar to the Top of the screen

I want to create DetailActivity for My app . I want To achieve layout some thing like This .

initToolbar();
initTablayout();
}
//============================ Init Toolbar ===================================//

Android drag margin for navigation drawer is off screen

I have recently created an app called Hoops and I have been developing it for quite some time now. However, the main problem that I seem to be getting, is that the navigation drawer's swipe margin is off screen and other users find it incredibly hard to use the navigation drawer's swipe feature. The menu button works just fine though. I have looked at other tutorials online and all of them seem to be showing the same answer as the one in the forum I have linked: Set drag margin for Android Navigation Drawer
However, I have tried this solution, and it does not seem to be working for me. If anyone has any ideas why it is not working please can you help me out. Here is the coding for the Main activity with the navigation drawer below:
package com.jehan.sportstutorials;
import android.content.Intent;

If anyone wants a live example of the navigation drawers swipe feature not working you can test out my app in the app store. Here is the link: https://play.google.com/store/apps/details?id=com.jehan.sportstutorials
Summary: Does anyone know how to increase the navigation drawers drag margin, however not following the conventional methods stated in the link in my first paragraph? Help would be appreciated.

Check your R.layout.activity_main layout. Android Studio IDE, for some reason, sets 15dp margin to the topmost container of automatically-created Activity layouts. This could interfere with the Drawer.
Just check if the topmost Relative/Frame/Whichever Layout has any android:layout_marginX attributes set and remove them.
