Android Searchview plus ListView common use

In some apps, it's common to have a edittext below is a ListView interface, and in EditText, you can search for the current listview. Now let's start with Searchview + The ListView way to implement such a function

The main is the use of Searchview onquerytextchange content changes when listening and onquerytextsubmit click on the right of the Searchview to determine the search button monitoring

The main use of the ListView is to allow the ListView to filter lv_main.settextfilterenabled (TRUE);

and add Filter Lv_main.setfiltertext (NewText) to the ListView;//Set filter phrase

Lv_main.cleartextfilter ();//Clear the ListView filter

Self-feeling without EditText + listview in a good way, personally advocating the latter

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>
