Image I want the blank fragment when i click on the home, edit profile but its show everywhere signup activity because my content_main framelayout id is fragment and its call in mainactivity and its my signup page too (fragmentManager.beginTransaction().replace(R.id.fragment,editFragment).commit();) So how to solve this problem

In your MainActivity.java you are using
setContentView(R.layout.fragment_business);
But your drawer is in activity_main.xml
So your drawer is a null and you cannot add a listener to a null object.
Change the setContentView to
setContentView(R.layout.activity_main);

Fragment doesn't replace in Navigation Drawer

I'm creating a Navigation Drawer like this
MainActivity.java

setContentView(R.layout.activity_main);
Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
FloatingActionButton fab = (FloatingActionButton) findViewById(R.id.fab);
fab.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
Snackbar.make(view, "Replace with your own action", Snackbar.LENGTH_LONG)
.setAction("Action", null).show();
}
});
DrawerLayout drawer = (DrawerLayout) findViewById(R.id.drawer_layout);
ActionBarDrawerToggle toggle = new ActionBarDrawerToggle(
this, drawer, toolbar, R.string.navigation_drawer_open, R.string.navigation_drawer_close);
drawer.setDrawerListener(toggle);
toggle.syncState();
NavigationView navigationView = (NavigationView) findViewById(R.id.nav_view);
navigationView.setNavigationItemSelectedListener(this);
}
#Override
public void onBackPressed() {
DrawerLayout drawer = (DrawerLayout) findViewById(R.id.drawer_layout);
if (drawer.isDrawerOpen(GravityCompat.START)) {
drawer.closeDrawer(GravityCompat.START);
} else {
super.onBackPressed();
}
}
#Override

getMenuInflater().inflate(R.menu.main, menu);
return true;
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
// Handle action bar item clicks here. The action bar will
// automatically handle clicks on the Home/Up button, so long
// as you specify a parent activity in AndroidManifest.xml.
int id = item.getItemId();
//noinspection SimplifiableIfStatement
if (id == R.id.action_settings) {
return true;
}
return super.onOptionsItemSelected(item);
}
#SuppressWarnings("StatementWithEmptyBody")
#Override
public boolean onNavigationItemSelected(MenuItem item) {
// Handle navigation view item clicks here.
int id = item.getItemId();
FragmentManager fragmentManager = getSupportFragmentManager();
if (id == R.id.nav_home) {
// Handle the camera action
} else if (id == R.id.nav_articles) {
} else if (id == R.id.nav_videos) {
fragmentManager.beginTransaction()
.replace(R.id.content_frame, new FragmentVideo())
.addToBackStack(null)
.commit();
} else if (id == R.id.fb_posts) {
} else if (id == R.id.nav_share) {
} else if (id == R.id.nav_send) {
}
DrawerLayout drawer = (DrawerLayout) findViewById(R.id.drawer_layout);
drawer.closeDrawer(GravityCompat.START);
return true;
}
}
My FragmentVideo
import android.os.Bundle;
import android.support.v4.app.Fragment;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import com.paperwrrk.R;
public class FragmentVideo extends Fragment {
View myView;
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState){
myView = inflater.inflate(R.layout.fragment_video, container, false);
return myView;
}
}
But when I click on the item from Navigation Drawer second fragment doesn't replace or hide the first one, it is overlapping like this
Please see the screenshot

Use a container instead of using fragment tag
<FrameLayout
android:id="#+id/container"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:text="Hello World!" />
Now in activity
if(condition)
getSupportFragmentManager().beginTransaction().replace(R.id.container,new FirstFragment()).commit();
else
getSupportFragmentManager().beginTransaction().replace(R.id.container, new SecondFragment()).commit();
if this not works try to get the fragment container view ID..Here's the code:
transaction.replace(((ViewGroup)(getView().getParent())).getId(), fragment);

It works for me...
int id = item.getItemId();
android.app.Fragment fragment = null;
if (id == R.id.nav_profile) {
fragment = new ProfileActivity();
if (fragment != null) {
android.app.FragmentManager fragmentManager = getFragmentManager();
fragmentManager.beginTransaction()
.replace(R.id.content_frame, fragment).commit();
}

thank you in advance ;)

In your onItemClick method, you are breaking out of every case without anything and you implemented OnItemClickListener interface, nothing will happen if you do not specify what should happen in those cases. Please specify what you want in those cases instead of breaking out. You might add a toast to see what's going on,
like case 0: Toast.makeText(yourContext, "first item", Toast.LENGTH SHORT).show();
break;
