android - 导航 View 未调用 onNavigationItemSelected 方法

Question

我在 DrawerLayout 中使用 NavigationView，我不确定我是否忘记了什么，但只是在我单击它时隐藏了 Navigation。

这是我的代码:

主要 Activity .java:

  private void instantiateDrawerLayout() {
        Toolbar mToolbar = (Toolbar) generalContent.findViewById(R.id.toolbar);
        mToolbar.setBackgroundColor(getResources().getColor(R.color.colorMainActivity));
        setSupportActionBar(mToolbar);
        NavigationView navigationView = (NavigationView) findViewById(R.id.navigation_view);
        navigationView.setItemIconTintList(ColorStateList.valueOf(getResources().getColor(R.color.colorMainActivity)));
        navigationView.setNavigationItemSelectedListener(this);
        Log.d("instantiateDrawerLayout", "called");
        ActionBarDrawerToggle drawerToggle = new ActionBarDrawerToggle(this, mDrawer, mToolbar, R.string.drawer_open, R.string.drawer_close);
        mDrawer.setDrawerListener(drawerToggle);
        drawerToggle.syncState();
        ...
    }

  @Override
  public boolean onNavigationItemSelected(MenuItem menuItem) {
    Log.d("onNavigationItem", "called");
    final int itemId = menuItem.getItemId();
    Intent intent;
    switch (itemId) {
        case R.id.navigation_item_1:
            hideDrawer();
            break;
        case R.id.navigation_item_2:
            intent = new Intent(this, FirstActivity.class);
            startActivity(intent);
            this.finish();
            break;
        case R.id.navigation_item_3:
            intent = new Intent(this, SecondActivity.class);
            startActivity(intent);
            this.finish();
            break;
        case R.id.navigation_item_4:
            intent = new Intent(this, ThirdActivity.class);
            startActivity(intent);
            this.finish();
            break;
    }
    return false;
}

activity_general.xml

<android.support.v4.widget.DrawerLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:id="@+id/drawer_layout"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="@color/colorBackground">

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

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

菜单抽屉.xml

<menu xmlns:android="http://schemas.android.com/apk/res/android" >
    <!--All the items added without any grouping-->

    <item
        android:id="@+id/navigation_item_1"
        android:icon="@drawable/ic_number_1"
        android:title="@string/navigation_item_1" />
    <item
        android:id="@+id/navigation_item_2"
        android:icon="@drawable/ic_number_2"
        android:title="@string/navigation_item_2" />

    <item
        android:id="@+id/navigation_item_3"
        android:icon="@drawable/ic_number_3"
        android:title="@string/navigation_item_3" />
    <item
        android:id="@+id/navigation_item_4"
        android:icon="@drawable/ic_number_4"
        android:title="@string/navigation_item_4" />

</menu>

我解决了，是为了Layout中的orden。

如您所见，我将 NavigationView 放在第一位，这导致当我点击 NavigationView 时认为我点击了 LinearLayout，或者我认为这就是发生的事情。

只需更改顺序即可。
