片段导航抽屉中的静态标题

Question

我在adt中创建了一个Android项目，其导航类型为adt中提供的导航抽屉。 我想向抽屉添加一个静态标题Edittext小部件，使其不能滚动，并且在xml列表中导航抽屉的listview顶部是不可移动的，但是该标题应该一直保持静态，任何帮助将不胜感激。 我是否需要上载xml代码，我认为这是没有用的，因为问题很简单，但是如果有人想要xml代码，请问我，我将上载它。

这是我的activity_main.xml

<!-- A DrawerLayout is intended to be used as the top-level content view using                    
match_parent for both width and height to consume the full space available. -->
<android.support.v4.widget.DrawerLayout       
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:id="@+id/drawer_layout"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context="com.example.appname.MainActivity" >

<!--
     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:name="com.example.appname.NavigationDrawerFragment"
    android:layout_width="@dimen/navigation_drawer_width"
    android:layout_height="match_parent"
    android:layout_gravity="start" />

    </android.support.v4.widget.DrawerLayout>

这是我的fragment_navigation_drawer.xml

<ListView xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#eee"
android:choiceMode="singleChoice"
android:divider="@color/line_divider"
android:focusableInTouchMode="true"
android:dividerHeight="1dp"
android:padding="5dp"
tools:context="com.example.appname.NavigationDrawerFragment" />

NavigationDrawer不必是ListView ，它可以是任何东西。 在您的情况下，请尝试以下操作：

<?xml version="1.0" encoding="utf-8"?>
<android.support.v4.widget.DrawerLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/drawer_layout"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <!-- The main content view -->
    <FrameLayout
        android:id="@+id/flFragmentContainer"
        android:layout_width="match_parent"
        android:layout_height="match_parent" />

    <!-- The navigation drawer -->
    <RelativeLayout
        android:layout_width="240dp"
        android:layout_height="match_parent"
        android:layout_gravity="start"
        android:background="#111">

        <EditText
            android:id="@+id/etHeader"
            android:inputType="text"
            android:layout_width="match_parent"
            android:layout_height="wrap_content" />

        <ListView
            android:id="@+id/lvDrawer"
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:choiceMode="singleChoice"
            android:layout_below="@id/etHeader"
            android:divider="@android:color/transparent"
            android:dividerHeight="0dp" />
    </RelativeLayout>

</android.support.v4.widget.DrawerLayout>
