Question

我的Header布局中有一个图像和一个文本，它通过android.support.design.widget.NavigationView包含在内。图片将是用户的个人资料图片，文字将是我从会话管理员班级获得的名称。

如何以编程方式访问和编辑文本和图像，因为它只包含在NavigationView的定义中。

以下是代码：

 <android.support.design.widget.NavigationView
        xmlns:android="http://schemas.android.com/apk/res/android"
        xmlns:app="http://schemas.android.com/apk/res-auto"
        android:layout_width="wrap_content"
        android:layout_height="match_parent"
        android:layout_gravity="start"
        android:id="@+id/shitstuff"
        app:itemTextColor="@color/grey"
        app:menu="@menu/drawermenu"
        app:headerLayout="@layout/headerlayout"
        app:itemIconTint="@color/colorPrimary"
        android:layout_marginTop="0dp"

        />

在活动课上：

 mDrawerLayout = (DrawerLayout) findViewById(R.id.drawerLayout);
    mNavigationView = (NavigationView) findViewById(R.id.shitstuff) ;

    /**
     * Lets inflate the very first fragment
     * Here , we are inflating the TabFragment as the first Fragment
     */

    mFragmentManager = getSupportFragmentManager();
    mFragmentTransaction = mFragmentManager.beginTransaction();
    mFragmentTransaction.replace(R.id.containerView,new helpfragment()).commit();
    /**
     * Setup click events on the Navigation View Items.
     */

    mNavigationView.setNavigationItemSelectedListener(new NavigationView.OnNavigationItemSelectedListener() {
        @Override
        public boolean onNavigationItemSelected(MenuItem menuItem) {
            mDrawerLayout.closeDrawers();


            if (menuItem.getItemId() == R.id.nav_item_home) {
                Intent i = new Intent(help.this, home.class);
                startActivity(i);
            }



            if (menuItem.getItemId() == R.id.nav_item_tenant) {
                Intent i = new Intent(help.this, rentertabview.class);
                startActivity(i);
            }
            if (menuItem.getItemId() == R.id.nav_item_profile) {
                Intent i = new Intent(help.this, profile.class);
                startActivity(i);
            }


            if (menuItem.getItemId() == R.id.nav_item_owner) {
                Intent i = new Intent(help.this, ownertabview.class);
                startActivity(i);
            }

            if (menuItem.getItemId() == R.id.nav_item_services) {
                Intent i = new Intent(help.this, services.class);
                startActivity(i);
            }

            return false;
        }

    });

    /**
     * Setup Drawer Toggle of the Toolbar
     */

    android.support.v7.widget.Toolbar toolbar = (android.support.v7.widget.Toolbar) findViewById(R.id.toolbar);
    ActionBarDrawerToggle mDrawerToggle = new ActionBarDrawerToggle(this,mDrawerLayout, toolbar,R.string.app_name,
            R.string.app_name);

    mDrawerLayout.setDrawerListener(mDrawerToggle);

    mDrawerToggle.syncState();

请详细说明。真的会感谢你。
