java - 不调用onNavigationItemSelected

当有人单击导航 View 时，我想调用onNavigationItemSelected。该代码未调用onNavigationItemSelected方法:

 public boolean onNavigationItemSelected(MenuItem menuItem) {
    Log.d("Hello","called navigation");

    switch (menuItem.getItemId()) {
        case R.id.home:
            mDrawerLayout.closeDrawer(GravityCompat.START);
            break;
        default:
            mDrawerLayout.closeDrawer(GravityCompat.START);
            break;

    }

    return false;
}

activity_main.xml是:

<android.support.v4.widget.DrawerLayout 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"
android:id="@+id/drawer_layout"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context="slidenerd.vivz.navigationviewdemo.MainActivity">

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

    <android.support.v7.widget.Toolbar
        android:id="@+id/app_bar"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:background="@color/colorPrimary"
        android:minHeight="?attr/actionBarSize"
        app:theme="@style/ThemeOverlay.AppCompat.Dark.ActionBar" />



</LinearLayout>

<android.support.design.widget.NavigationView
    android:id="@+id/main_drawer"
    android:layout_width="wrap_content"
    android:layout_height="match_parent"
    android:layout_gravity="start"
    app:headerLayout="@layout/drawer_header"
    app:itemIconTint="@color/colorAccent"
    app:itemTextColor="@color/colorTextSecondary"
    app:menu="@menu/menu_drawer" />

navigation_menu是:

<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android">
    <!--All the items added without any grouping-->
    <item
        android:id="@+id/home"
        android:icon="@drawable/ic_home"
        android:title="@string/home" />

    <item
        android:id="@+id/statistics"
        android:icon="@drawable/ic_trending_up"
        android:title="@string/statistics" />

    <item
        android:id="@+id/navigation_item_3"
        android:icon="@drawable/ic_pencil"
        android:title="@string/navigation_item_3" />
 </menu>

但是，代码无法正常工作。请帮我解决问题。

最佳答案

您应该设置NavigationView.setNavigationItemSelectedListener()
