지도가 레이아웃에 포함되어 있으면 의도 활동이 시작되지 않습니다.

Question

내 클래스가 확장됩니다 FragmentActivity ...지도가 레이아웃에 포함되지 않으면 의도 활동이 시작됩니다. 그러나 불행히도 activity_main_map이 activity_main_nav에 포함 된 경우 의도 활동이 시작되지 않습니다. 누군가 나를 도울 수 있습니까?

public class MainMapActivity extends FragmentActivity 

@Override 
protected void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.activity_main_nav); 

    setUpToolbarDrawer(); 
    setUpNavView(); 
} 

@SuppressWarnings("StatementWithEmptyBody") 
@Override 
public boolean onNavigationItemSelected(MenuItem item) { 
    int id = item.getItemId(); 

    if (id == R.id.add_bus) { 
     Intent intent = new Intent(MainMapActivity.this, AddBusActivity.class); 
     startActivity(intent); 
    } else if (id == R.id.add_driver) { 
     Intent intent = new Intent(MainMapActivity.this, AddDriverActivity.class); 
     startActivity(intent); 
    } 

    DrawerLayout drawer = (DrawerLayout) findViewById(R.id.drawer_layout); 
    drawer.closeDrawer(GravityCompat.START); 
    return true; 
} 

public void setUpToolbarDrawer() { 
    Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar); 
    DrawerLayout drawerLayout = (DrawerLayout) findViewById(R.id.drawer_layout); 
    ActionBarDrawerToggle toggle = new ActionBarDrawerToggle(this, drawerLayout, toolbar, R.string.navigation_drawer_open, R.string.navigation_drawer_close); 
    drawerLayout.setDrawerListener(toggle); 
    toggle.syncState(); 
} 

public void setUpNavView() { 
    NavigationView navigationView = (NavigationView) findViewById(R.id.nav_view); 
    navigationView.setNavigationItemSelectedListener(this); 
} 

activity_main_nav

<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_main" 
    app:menu="@menu/activity_main_drawer" /> 

<include 
    layout="@layout/activity_main_map" 
    android:layout_width="match_parent" 
    android:layout_height="wrap_content" /> 

activity_main_map

<fragment 
    android:id="@+id/map" 
    android:name="com.google.android.gms.maps.SupportMapFragment" 
    android:layout_width="match_parent" 
    android:layout_height="match_parent" />

난 그냥 그냥 이런 LinearLayout 내부 appBar 및 포함 된지도를 넣어.

<?xml version="1.0" encoding="utf-8"?> 

<LinearLayout 
    android:orientation="vertical" 
    android:layout_width="match_parent" 
    android:layout_height="match_parent"> 

    <include xmlns:android="http://schemas.android.com/apk/res/android" 
     layout="@layout/app_bar_main" 
     android:layout_width="match_parent" 
     android:layout_height="wrap_content" /> 

    <include 
     layout="@layout/activity_main_map" 
     android:layout_width="match_parent" 
     android:layout_height="wrap_content" /> 
</LinearLayout> 

<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_main" 
    app:menu="@menu/activity_main_drawer" />
