android searchView加ListView共同使用

在一些app内,很常见上面一个edittext 下面是个listview的界面,在edittext中输入东西,就可以达到搜索当前listview的目的.现在我们首先使用searchview + listview的方式来实现这样的功能

主要就是使用了searchview的onQueryTextChange内容改变的时候监听 以及onQueryTextSubmit点击了searchview右侧的确定搜索按钮监听

listview主要用到的是,允许listview进行过滤lv_main.setTextFilterEnabled(true);

以及为listview添加过滤  lv_main.setFilterText(newText);// 设置过滤词组

lv_main.clearTextFilter();// 清除listview的过滤

自我感觉没有edittext + listview的方式好,个人推崇后者

xml:

<RelativeLayout 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"
    tools:context="com.example.testsearchview.MainActivity" >

    <SearchView
        android:id="@+id/searchView1"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_alignParentLeft="true"
        android:layout_alignParentTop="true" >
    </SearchView>

    <ListView
        android:id="@+id/lv_main"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_alignLeft="@+id/searchView1"
        android:layout_below="@+id/searchView1"
        android:background="#000"
        android:layout_marginTop="14dp" >
    </ListView>

</RelativeLayout>
