Android EditText + ListView Implementation Search for content in ListView

I used to think that something was in the edittext. You can then detect the contents of the ListView very tall. I've never tried it. Now I've met you in the project. The results found quite simple, the effect is good, mainly to use the EditText TextChange monitoring and filtering of the ListView. Directly below:

Xml:

<linearlayout 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:orientation= "vertical"    tools:context= "com.example.testedittextlistview.MainActivity" >    <include layout= "@layout/myedittext"/>    <listview        android:id= "@+id/lv_main"        android:layout_ Width= "Match_parent"        android:layout_height= "match_parent"        android:background= "#000" >    </ Listview></linearlayout>
