and display text of item you click in listview .
Let start with layout file :
activity_main.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=".MainActivity" >

<EditText

android:layout_alignParentLeft="true"
android:layout_alignParentTop="true"
android:hint="Search here"
android:layout_marginLeft="28dp"
android:ems="10" />
<ListView
android:id="@+id/listView1"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:layout_below="@+id/editText1" >
</ListView>
</RelativeLayout>
single_item.xml (for each line in listview)
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"

sub_activity.xml

</RelativeLayout>
Now we have two activity and one arrayadapter custome :
