Android gets phone contact number and returns results _android

Before doing a little exercise need to get the phone number of contact person, by looking at the relevant information, I try to write a small example, can be successfully obtained.
First, you need to get permissions in Androidmanifest.xml

<uses-permission android:name= "Android.permission.READ_CONTACTS"/>

XML layout file

<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" >

  <textview 
    android:layout_width= "Wrap_content"
    android: layout_height= "Wrap_content"
    android:text= "phone number is:"/> <edittext android:id= " 
    @+id/editnumber"
    android:layout_width= "match_parent"
    android:layout_height= "wrap_content"
    android:editable= " False "/>
  <button 
    android:id=" @+id/buttonquary "
    android:layout_width=
    " Wrap_content " android:layout_height= "Wrap_content"
    android:text= "query Contacts"/>

</LinearLayout>

            Strnumber = Strnumber.replace ("", "");
