沒有列表的Android導航抽屜

Question

我試圖建立一個不使用列表和列表適配器的導航抽屜。

我想在導航抽屜裏只有一個靜態佈局。

我正在使用Android Studio生成導航抽屜項目的代碼存根。而且我可以編輯「fragment_navigation_drawer.xml」 - 但是當我添加任何東西給它，除了一個ListView我得到下面的異常在MainActivity

例外：

    super.onCreate(savedInstanceState); 

    setContentView(R.layout.activity_main); // Exception on this line 
mNavigationDrawerFragment = (NavigationDrawerFragment) getSupportFragmentManager().findFragmentById(R.id.navigation_drawer);

// Set up the drawer. 
mNavigationDrawerFragment.setUp(R.id.navigation_drawer, (DrawerLayout) findViewById(R.id.drawer_layout));

主要活動XML：

    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"

如何更換與抽屜式導航只是一個靜態佈局ListView的？

謝謝。

Answer 1

我用相對佈局替換了列表視圖。以下xml允許我有一個從左側滑入的頂部和底部菜單。我也有底部菜單下的版本文本（在你想知道那裏的文本視圖的情況下）。我不確定，但我認爲您可以將List視圖替換爲從視圖組派生的任何視圖。

<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"

      <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_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:text="Version:"

        android:textColor="@color/GreyMid" 
        android:layout_alignParentBottom="true"/> 
    </RelativeLayout> 
</FrameLayout> 

希望這有助於。

這裏是創建菜單的代碼。
