Android 如何通过活动中的绑定从抽屉标题布局获取视图？

这是我的activity_main.xml：

<?xml version="1.0" encoding="utf-8"?>
<layout xmlns:android="http://schemas.android.com/apk/res/android"
        xmlns:app="http://schemas.android.com/apk/res-auto"
        xmlns:tools="http://schemas.android.com/tools"
        tools:context="MainActivity"
    >
    <!-- A DrawerLayout is intended to be used as the top-level content view using match_parent for both width and height to consume the full space available. -->
    <android.support.v4.widget.DrawerLayout
        android:id="@+id/drawer_layout"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        >

        <!-- As the main content view, the view below consumes the entire
             space available using match_parent in both dimensions. -->

        <RelativeLayout
            android:layout_width="match_parent"
            android:layout_height="match_parent">

            <LinearLayout
                android:id="@+id/ll_container"
                android:layout_width="match_parent"
                android:layout_height="match_parent"
                android:orientation="vertical">

                <android.support.v7.widget.Toolbar
                    android:id="@+id/my_awesome_toolbar"
                    android:layout_width="match_parent"
                    android:layout_height="wrap_content"
                    android:background="@android:color/black"
                    android:fitsSystemWindows="true"
                    >

                    <TextView
                        android:id="@+id/toolbar_title"
                        android:layout_width="wrap_content"
                        android:layout_height="wrap_content"
                        android:layout_marginLeft="10dp"
                        android:layout_marginStart="10dp"
                        android:textColor="@android:color/white"
                        android:textSize="@dimen/abc_text_size_title_material_toolbar"
                        tools:text="@string/default_toolbar_title"/>

                </android.support.v7.widget.Toolbar>


                <FrameLayout
                    android:id="@+id/container"
                    android:layout_width="match_parent"
                    android:layout_height="match_parent">

                </FrameLayout>
            </LinearLayout>

            <android.support.design.widget.FloatingActionButton
                android:id="@+id/fab_fuf"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:layout_alignParentBottom="true"
                android:layout_alignParentEnd="true"
                android:layout_alignParentRight="true"
                android:layout_marginBottom="20dp"
                android:layout_marginEnd="20dp"
                android:layout_marginRight="20dp"
                android:src="@drawable/flamme"
                app:fabSize="normal"
                />
        </RelativeLayout>

        <android.support.design.widget.NavigationView
            android:id="@+id/navigation_view"
            android:layout_width="wrap_content"
            android:layout_height="match_parent"
            android:layout_gravity="start"
            android:background="@android:color/black"
            **app:headerLayout="@layout/drawer_header"**
            app:itemTextColor="@color/drawer_item_color_selector"
            app:menu="@menu/menu_drawer"/>

    </android.support.v4.widget.DrawerLayout>
</layout>

如您所见，我可以通过绑定获得直接位于activity_main.xml布局中的视图，但是当我试图获取的视图不在那里时，我无法在绑定对象中看到变量

drawer_header.xml：

    <?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="96dp"
                xmlns:tools="http://schemas.android.com/tools"
                android:background="@android:color/black"
                android:theme="@style/ThemeOverlay.AppCompat.Dark">


    <TextView
        android:id="@+id/tv_logged_user_email"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_centerVertical="true"
        android:layout_marginLeft="16dp"
        tools:text="@string/login_placeholder_email"
        android:textAllCaps="true"
        android:textAppearance="@style/TextAppearance.AppCompat.Body2"
        android:textSize="20sp"/>


</RelativeLayout>

我也有同样的问题

一种解决方法是膨胀标题视图并以编程方式添加它

像这样：

DrawerHeaderBinding drawerHeaderBinding = DrawerHeaderBinding.inflate(LayoutInflater.from(navigationView.getContext()));
navigationView.addHeaderView(drawerHeaderBinding.getRoot());
drawerHeaderBinding.tvLoggedUserEmail = "email";
drawerHeaderBinding.executePendingBindings();

---

因此，删除app:headerLayout并按编程方式执行。不过，我认为谷歌应该在设计库或数据绑定库中解决核心问题。

你可以这样做。首先初始化导航视图

    NavigationView navigationView = (NavigationView) findViewById(R.id.navigation_view);

然后初始化navigationView内部的所有视图

    CircleImageView circleView = (CircleImageView) navigationView.findViewById(R.id.circleView);
    TextView name = (TextView) navigationView.findViewById(R.id.name);
    TextView email = (TextView) navigationView.findViewById(R.id.email);
    LinearLayout header = (LinearLayout) navigationView.findViewById(R.id.header);

然后，您可以根据需要使用这些视图。 例如：

更新的解决方案（2015年11月13日） 解决方案：将设计支持库更新为

23.1.1

：

设计支持库的更改

23.1.1

：

• 将

  getHeaderView

  方法添加到

  NavigationView

  类中
• 修复了运行Android 4.0（API级别15）及更低版本的设备上的

  FloatingActionButton

  对象的透明背景问题。（第183315期）

原液 我不知道为什么没有提供标题视图的方法 以编程方式附加

相反，这里有两种解决方案：

NavigationView-NavigationView=（NavigationView）findViewById（R.id.navigation）；
视图标题视图=导航视图。充气标题视图（右布局。标题\ U布局）
ImageView iv=（ImageView）headerview.findViewById（R.id.your\u image\u视图）

或：

NavigationView-NavigationView=（NavigationView）findViewById（R.id.navigation）；
View headerView=布局Flater.from（this）.充气（R.layout.header\u布局，navigationView，false）；
navigationView.addHeaderView（headerView）；
ImageView iv=（ImageView）headerView.findViewById（R.id.yourImageView）

• 编辑gradle文件以更新com.android.support库至23.1.1或更高版本

• 使用

  navigationView.getHeaderView（i）

  ，其中

  i

  是

  headerview

  的索引。如果您刚刚在布局上定义了此视图，则为

  0

我已经从Android sdk管理器更新了构建工具，那么

23.1.0

对我来说也很好

我使用的是

buildToolsVersion“23.0.2”

在此之前它是

23.0.1

无需使用：

(View) navigationView.findViewById(R.id.idOfViewFromHeaderView);

在您的活动中，您可以直接使用：

(View) findViewById(R.id.idOfViewFromHeaderView);

它对我有用

MainActivity.java:

    NavigationView navigationView = (NavigationView) findViewById(R.id.nav_view);

    NavHeaderMainBinding binding = DataBindingUtil.inflate(getLayoutInflater(), R.layout.nav_header_main, navigationView, false);

    navigationView.addHeaderView(binding.getRoot());

我有一个稍微干净一点的解决方案，我不必用负责膨胀和向NavigationView添加标题视图的代码“污染”片段/活动。我为NavigationView实现了扩展类。我是这样做的：

View headerView = binding.navigationView.getHeaderView(0);
DrawerHeaderBinding headerBinding = DrawerHeaderBinding.bind(headerView);

我的活动布局：

<data>
    <variable
        name="dashboard"
        type="ramps.view.model.DashboardScreenViewModel"/>
</data>

<android.support.v4.widget.DrawerLayout
    android:id="@+id/drawer_layout"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:fitsSystemWindows="true"
    tools:openDrawer="start">

    <include
        layout="@layout/activity_dashboard"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        bind:dashboard="@{dashboard}"
        />

    <android.support.design.widget.NavigationView
        android:id="@+id/nav_view"
        android:background="@color/white"
        android:layout_width="wrap_content"
        android:layout_height="match_parent"
        android:layout_gravity="start"
        android:fitsSystemWindows="true"
        app:navigationItemSelectedListener="@{dashboard.onMenuItemSelected}"
        app:model="@{dashboard.score}"
        app:menu="@menu/activity_main_drawer"/>

</android.support.v4.widget.DrawerLayout>

ActivityMainBinding activityMainBinding = DataBindingUtil.setContentView(this,
                R.layout.activity_main);
activityMainBinding.setNavigationItemSelectedListener(this);/* with this line navigation menu item selection events are handled in onNavigationItemSelected() specified in navigation_view_header.xml*/

NavigationViewHeaderBinding navigationViewHeaderBinding = DataBindingUtil.inflate(getLayoutInflater(), R.layout.navigation_view_header,activityMainBinding.navigationView,false);
        activityMainBinding.navigationView.addHeaderView(navigationViewHeaderBinding.getRoot());

View headerContainer = navigationView.getHeaderView(0); // This returns the container layout from your navigation drawer header layout file (e.g., the parent RelativeLayout/LinearLayout in your my_nav_drawer_header.xml file)
TextView textView2 = (TextView)headerContainer.findViewById(R.id.textView2);
textView2.setText("Sorted!");

只要把这个类放在你项目的任何地方。以及标题的布局：

<layout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:bind="http://schemas.android.com/apk/res-auto"
>

<data>

    <import type="android.view.View"/>

    <variable
        name="score"
        type="ramps.view.model.ScoreViewModel"/>
</data>

<LinearLayout
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:background="@color/graphite"
    android:gravity="bottom"
    android:orientation="vertical"
    android:paddingBottom="@dimen/activity_vertical_margin_large"
    android:paddingLeft="@dimen/activity_horizontal_margin"
    android:paddingRight="@dimen/activity_horizontal_margin"
    android:paddingTop="@dimen/activity_vertical_margin_large"
    android:theme="@style/ThemeOverlay.AppCompat.Dark">

    <include
        android:id="@+id/player_details_header_score"
        layout="@layout/view_avatar_score_header"
        bind:score="@{score}"/>

</LinearLayout>

如果设置

应用程序：headerLayout=“@layout/drawer\u header

，则无需再次对视图进行充气。只需使用

.bind

而不是

。充气即可

您可以获取已膨胀的标题视图，并按如下方式进行绑定：

View headerView = binding.navigationView.getHeaderView(0);
DrawerHeaderBinding headerBinding = DrawerHeaderBinding.bind(headerView);

用数据绑定库试试这个，它适合我

navigation\u view\u header.xml:

    NavigationView navigationView = (NavigationView) findViewById(R.id.nav_view);

    NavHeaderMainBinding binding = DataBindingUtil.inflate(getLayoutInflater(), R.layout.nav_header_main, navigationView, false);

    navigationView.addHeaderView(binding.getRoot());

</android.support.v4.widget.DrawerLayout>

并确保您的活动实现了导航视图。OnNavigationItemSelectedListener在这里是一个非常简单的解决方案。假设您将导航视图添加为

<android.support.design.widget.NavigationView
    android:id="@+id/navigationView"
    android:layout_width="wrap_content"
    android:layout_height="match_parent"
    android:layout_gravity="start"
    android:fitsSystemWindows="true"
    app:headerLayout="@layout/my_nav_drawer_header"
    app:menu="@menu/menu_nav_drawer"/>

无需膨胀或干扰现有代码等。
只需放置navigationView.getHeaderView（0），然后使用任何视图

        TextView profile,info;
        NavigationView navigationView = (NavigationView) findViewById(R.id.nav_view);
        profile = navigationView.getHeaderView(0).findViewById(R.id.profile);
        info = navigationView.getHeaderView(0).findViewById(R.id.info);
        profile.setOnClickListener(this);
        info.setOnClickListener(this);

要保持layout_height中指定的RelativeLayout的高度，请将RelativeLayout放入框架布局：
您注意到design-23.1.0中的更改了吗？我的代码现在无法工作。这不使用绑定。我知道怎么做。但是谢谢。只需更新gradle文件以获得23.1.1和getHeaderView（int index）方法将在那里。救生衣！！+1..但你必须删除app:headerLayout=“@layout/header\u left”“从xml中，否则它将膨胀两个标题…您需要描述您所做的，而不仅仅是发布代码。。。为了使他人的利益最大化，这个回答应该被接受。非常好的帖子。这让人困惑，你能展示ScoreViewModel类吗？这可能是最简单的解决方案。farI的最佳解决方案发现它非常有用。工作很有魅力。
