Query contacts in Contacts?
Cursor CR =getcontentresolver (). query (ContactsContract.Contacts.CONTENT_URI, NULL, null,null, NULL);

What if we just want to get the phone number?
Cursor phone = cr.query (Contactscontract.commondatakinds.phone.content_uri,null, ContactsContract.CommonDataKinds.Phone.CONTACT_ID + "=" +contactid, null, NULL);

Replace the above statement with the following:
Cursor phone = cr.query (Contactscontract.commondatakinds.phone.content_uri,null, ContactsContract.CommonDataKinds.Phone.CONTACT_ID + "=" +contactid + "+" + Contactscontract.commondatakinds.phone.type+ "=" + ContactsContract.CommonDataKinds.Phone.TYPE_MOBILE, null,null);
ContactsContract.CommonDataKinds.Phone.TYPE represents the type of contact phone, which corresponds to the following:
Type_mobile: Mobile phone number
Type_home: Residential Phone
Type_work: Company Phone

Finally remember to read the contact's API in the Androidmanifest.xml statement:
<uses-permissionandroid:name= "Android.permission.READ_CONTACTS"/>
