Question

所以，我有这个结构的NavigationView：

<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:itemIconTint="@color/drawer_item"
    app:itemTextColor="@color/drawer_item"
    app:itemBackground="@drawable/drawer_item"

    app:headerLayout="@layout/nav_header"
    app:menu="@menu/nav_menu" />

它位于main_activity.xml上，问题是当我尝试在headerLayout“@ layout / nav_header”中的布局中创建具有此结构的TextView时：

<LinearLayout
    android:orientation="vertical"
    android:background="@drawable/mat_bg1"
    android:layout_height="@dimen/header_height"
    android:clickable="true"
    android:layout_width="match_parent"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:android="http://schemas.android.com/apk/res/android">

    <LinearLayout
        android:orientation="vertical"
        android:background="@color/background_floating_material_light"
        android:layout_height="wrap_content"
        android:layout_width="match_parent"
        xmlns:app="http://schemas.android.com/apk/res-auto"
        xmlns:android="http://schemas.android.com/apk/res/android"
        android:paddingTop="@dimen/header_top_location_padding"
        android:clickable="true"
        android:id="@+id/nav_location"
        android:paddingLeft="@dimen/header_left_padding"
        android:paddingBottom="@dimen/header_left_padding"
        android:paddingRight="@dimen/header_left_padding"
        >

        <TextView
            android:id="@+id/locationSettings"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:clickable="true"
            android:text="VALENCIA"
            android:layout_gravity="center_horizontal"
            android:foregroundGravity="center_horizontal"
            android:gravity="center_horizontal"
            android:textColor="@color/accentColor"/>



    </LinearLayout> 
    [...]

问题是，当单击该布局中的TextView“locationSettings”时，我无法设置任何Clickable操作。

    protected void onCreate(Bundle savedInstanceState) {

    super.onCreate(savedInstanceState);
    setContentView(com.nite.R.layout.activity_main);

    setToolbar();

    drawerLayout = (DrawerLayout) findViewById(com.nite.R.id.drawer_layout);

    final NavigationView menu = (NavigationView) findViewById(com.nite.R.id.nav_view);

    if (menu != null) {
        setupDrawerContent(menu);
    }

    final View headerView = getLayoutInflater().inflate(R.layout.nav_header, menu, false);

    final TextView tv = (TextView) headerView.findViewById(R.id.locationSettings);

    tv.setOnClickListener(new View.OnClickListener() {

        @Override
        public void onClick(View v) {
            // TODO Auto-generated method stub
            //DO you work here
            Toast.makeText(getApplicationContext(), "Hey There",Toast.LENGTH_LONG);
            tv.setText("AAA");
        }

    });

        Fragment fragment = new HomeF();
        FragmentManager fragmentManager = getSupportFragmentManager();
        fragmentManager
                .beginTransaction()
                .replace(com.nite.R.id.main_content, fragment)
                .commit();

        //drawerLayout.closeDrawers();
        setTitle(HomeF.ARG_SECTION_TITLE);


}

知道为什么吗？顺便说一下，我可以通过Toast从TextView中检索getText，所以我正确引用了TextView，但无法设置可点击的事件......

感谢。

删除app:headerLayout="@layout/nav_header" 并以编程方式添加标题视图：

View headerView = getLayoutInflater().inflate(R.layout.nav_header_main, navigationView, false);
navigationView.addHeaderView(headerView);

在NavigationView headerLayout Android中使用onClick时出错
