我试图在不使用列表和列表适配器的情况下构建导航抽屉。
我想在导航栏中只有一个静态布局。
我使用Android Studio为Navigation Drawer项目生成了代码存根。我能够编辑＆＃34; fragment_navigation_drawer.xml＆＃34; - 但是当我在listView之外添加任何东西时，我在MainActivity中得到以下异常
例外：

主要活动代码：
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main); // Exception on this line
mNavigationDrawerFragment = (NavigationDrawerFragment) getSupportFragmentManager().findFragmentById(R.id.navigation_drawer);
mTitle = getTitle();
// Set up the drawer.
mNavigationDrawerFragment.setUp(R.id.navigation_drawer, (DrawerLayout) findViewById(R.id.drawer_layout));
}
主要活动XML：
<!-- As the main content view, the view below consumes the entire
space available using match_parent in both dimensions. -->
<FrameLayout android:id="@+id/container" android:layout_width="match_parent"
android:layout_height="match_parent" />
<!-- android:layout_gravity="start" tells DrawerLayout to treat
this as a sliding drawer on the left side for left-to-right
languages and on the right side for right-to-left languages.
If you're not building against API 17 or higher, use
android:layout_gravity="left" instead. -->
<!-- The drawer is given a fixed width in dp and extends the full height of
the container. -->
<fragment android:id="@+id/navigation_drawer"
android:layout_width="@dimen/navigation_drawer_width" android:layout_height="match_parent"
android:layout_gravity="start"
tools:layout="@layout/fragment_navigation_drawer" />
如何在导航抽屉中仅使用静态布局替换listView？
感谢。
答案 0 :(得分：1)
我用相对布局替换了列表视图。以下xml允许我有一个从左侧滑入的顶部和底部菜单。我还在底部菜单下面有版本文本（如果你想知道那里的文本视图）。我不确定，但我认为您可以使用从View Group派生的任何视图替换List视图。
<ImageView
android:id="@+id/playerBGFill"
android:layout_height="match_parent"
android:layout_width="match_parent"
android:scaleType="centerCrop"
android:layout_marginLeft="@dimen/main_neg_10sp"
android:layout_marginRight="@dimen/main_neg_10sp"
android:layout_marginTop="@dimen/main_neg_10sp"
android:src="@drawable/bg_texture2"
android:alpha="0.6"/>
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="match_parent">
<include layout="@layout/login_screen"/>
<include layout="@layout/system_list_popup"/>
<LinearLayout
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:id="@+id/mainView">
<include layout="@layout/nightlife_titlebar"/>
<com.hdms.manager.Fragments.NightlifeViewPager
android:id="@+id/contentViewPager"
android:layout_width="match_parent"
android:layout_height="match_parent" />
<LinearLayout android:id="@+id/pagination"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="horizontal">
</LinearLayout>
</LinearLayout>
</RelativeLayout>
</FrameLayout>
<!-- navigation drawer -->
<FrameLayout android:id="@+id/left_drawer"
android:layout_width="@dimen/main_280sp"
android:layout_height="match_parent"
android:layout_gravity="start"
android:choiceMode="singleChoice"
android:divider="@color/Red"
android:dividerHeight="0dp"
android:background="@drawable/menudrawer_bg">
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="match_parent">
<ListView android:id="@+id/left_drawer_menu"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_alignParentTop="true"
android:layout_above="@+id/left_drawer_bottom"/>
<ListView android:id="@+id/left_drawer_bottom"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_above="@+id/versionText"/>
<TextView android:id="@+id/versionText"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:gravity="center"
android:textSize="@dimen/main_12sp"
android:text="Version:"
android:textAlignment="center"
android:textColor="@color/GreyMid"
android:layout_alignParentBottom="true"/>
</RelativeLayout>
</FrameLayout>
希望这有帮助。
以下是创建菜单的代码。
