    android:layout_width="match_parent"
    android:layout_height="@dimen/nav_header_height"
    android:background="@drawable/side_nav_bar"
    android:gravity="bottom"
    android:orientation="vertical"
    android:paddingBottom="@dimen/activity_vertical_margin"
    android:paddingLeft="@dimen/activity_horizontal_margin"
    android:paddingRight="@dimen/activity_horizontal_margin"
    android:paddingTop="@dimen/activity_vertical_margin">

    <ImageView
        android:id="@+id/profpic"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:paddingTop="@dimen/nav_header_vertical_spacing"
        android:src="@android:drawable/sym_def_app_icon" />

</LinearLayout>

- und dies ist die java-Datei, wo muss ich das Holen prof_pic aus
.java-Klasse-Datei

public class Testing2 extends AppCompatActivity
        implements NavigationView.OnNavigationItemSelectedListener {


    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_testing2);

        Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
        setSupportActionBar(toolbar);

        ////////Code is used to fetch the user name////////////
        Bundle b = getIntent().getExtras();


        NavigationView navigationView = (NavigationView) findViewById(R.id.nav_view);
        navigationView.setNavigationItemSelectedListener(this);
        TextView facebookName = (TextView) navigationView.getHeaderView(0).findViewById(R.id.manner);
        TextView Email = (TextView) navigationView.getHeaderView(0).findViewById(R.id.email);
        ImageView profilePictureView = (ImageView) navigationView.getHeaderView(0).findViewById(R.id.profpic);

        ////////Code is used to display the user name after fetching it from other activity////////////
        facebookName.setText(b.getCharSequence("name"));
        Email.setText(b.getCharSequence("email"));
        profilePictureView.setProfileId();

        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();

  } 

Dies ist die .java-Datei, wo ich früher zu Holen, den Benutzernamen,die E-mail-Id und prof pic
