Android 如何将SearchView添加到导航抽屉中?

Android 如何将SearchView添加到导航抽屉中?,android,android-layout,Android,Android Layout,我开发了一个具有可扩展列表视图的导航抽屉,如下所示 <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"&g

我开发了一个具有可扩展列表视图的导航抽屉,如下所示

<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 -->
    <fragment 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:id="@+id/map" tools:context=".HomeActivity"
        android:name="com.google.android.gms.maps.SupportMapFragment" />

    <!-- The navigation drawer-->
    <ExpandableListView android:id="@+id/left_drawer"
        android:layout_width="240dp"
        android:layout_height="match_parent"
        android:layout_gravity="start"
        android:choiceMode="singleChoice"
        android:divider="@android:color/transparent"
        android:dividerHeight="0dp"
        android:background="#111"
        android:listSelector = "@drawable/selector_list_item">
    </ExpandableListView>
</android.support.v4.widget.DrawerLayout>
我犯了个错误

java.lang.UnsupportedOperationException: addView(View, LayoutParams) is not supported in AdapterView

谢谢,ExpandableListView不能添加任何子项–这些子项由适配器管理。如果希望将
SearchView
作为列表的一部分,可以将其作为标题添加到适配器中。但是将抽屉实现为一个片段,该片段将同时包含
SearchView
ExpandableListView
,这将是一个更好的解决方案。

您可以为导航抽屉设置一个片段,并将自定义视图设置为该片段

 <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 -->
     <fragment 
       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:id="@+id/map"        
       tools:context=".HomeActivity"
       android:name="com.google.android.gms.maps.SupportMapFragment" />

<!-- The navigation drawer-->

    <fragment
       android:id="@+id/menufragment"
       android:name="com.example.fragments.MenuDrawer"
       android:layout_width="match_parent"
       android:layout_gravity="start"
       android:layout_height="match_parent" />
  </android.support.v4.widget.DrawerLayout>

我认为在
活动中使用
操作栏
工具栏
添加
搜索视图
将是一个很好的解决方案。您可以这样尝试:

首先,将
SearchView
添加到
菜单中:

<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android"
      xmlns:yourapp="http://schemas.android.com/apk/res-auto" >
    <item android:id="@+id/action_search"
          android:title="@string/action_search"
          android:icon="@drawable/ic_action_search"
          yourapp:showAsAction="ifRoom|collapseActionView"
          yourapp:actionViewClass="android.support.v7.widget.SearchView" />
</menu>
如果你想知道更多细节,请查看

<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android"
      xmlns:yourapp="http://schemas.android.com/apk/res-auto" >
    <item android:id="@+id/action_search"
          android:title="@string/action_search"
          android:icon="@drawable/ic_action_search"
          yourapp:showAsAction="ifRoom|collapseActionView"
          yourapp:actionViewClass="android.support.v7.widget.SearchView" />
</menu>
@Override
public boolean onCreateOptionsMenu(Menu menu) {
    getMenuInflater().inflate(R.menu.main_activity_actions, menu);
    MenuItem searchItem = menu.findItem(R.id.action_search);
    SearchView searchView = (SearchView) MenuItemCompat.getActionView(searchItem);
    // Configure the search info and add any event listeners
    ...
    return super.onCreateOptionsMenu(menu);
}
