有没有办法在我的自定义列表视图上创建一个使用BaseAdapter而不是ArrayAdapter创建的搜索过滤器，因为我只遇到过在自定义列表视图中使用ArrayAdapters的方法。 Follwing是我遇到的Making a filter using Array Adapter
答案 0 :(得分：2)
如果你正在使用List集合，那么扩展ArrayAdapter - 它是BaseAdapter的子类。
覆盖getView方法（在您的情况下，只需稍加修改即可复制旧的getView代码）。
覆盖集合中的对象的toString并设置：
listView.setTextFilterEnabled(true);

以下是使用基本适配器创建的列表视图的示例。 我搜索了很多，但没有得到任何令人满意的解决方案。因此我想把它放在一起以便以后它可以帮助别人。
以下是 history_container.xml
的代码<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent" android:layout_height="fill_parent"
android:orientation="vertical">
<EditText android:layout_width="fill_parent" android:layout_height="wrap_content"
android:id="@+id/filter_text" />
<FrameLayout android:layout_width="fill_parent"
android:layout_height="fill_parent" android:id="@+id/historyContainerLayout" />
</LinearLayout>
以下是 history_list_view.xml
的代码<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_height="wrap_content" android:gravity="left|center"
android:layout_width="wrap_content" android:paddingBottom="5px"
android:paddingTop="5px" android:paddingLeft="5px">
<TextView android:text="@+id/historytext" android:id="@+id/historytext"
android:layout_width="wrap_content" android:layout_height="wrap_content"
android:layout_marginLeft="10px" android:textColor="#0099CC"/>
</LinearLayout>
以下是 history_schedule.xml
的代码<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical" android:layout_width="fill_parent"
android:layout_height="fill_parent">
<ScrollView android:id="@+id/scrollItemInfo"
android:layout_width="fill_parent" android:layout_height="1000dip">
<LinearLayout android:orientation="vertical"
android:layout_width="fill_parent" android:layout_height="fill_parent">
<ListView android:id="@+id/historylist" android:layout_height="1000dip"
android:layout_width="fill_parent"/>
</LinearLayout>
</ScrollView>
</LinearLayout>
抱歉，我无法以正确的格式放置代码。由于没有标签，这些内容已经发生了变化，这很不错。但为了方便用户，这也是一个很好的选择。 也许我的错是我无法以正确的格式发布。似乎我们无法发布xml文件内容。所以，想想布局的设计方式。
