下面这段代码放在方法中直接调用就OK。Activity

 <span style="font-size:18px;">//ContactsContract.CALLER_IS_SYNCADAPTER-->表示将所有与联系人有关联的数据库都删除了ContentResolver cResolver1=this.getContentResolver();Uri uri4=ContactsContract.RawContacts.CONTENT_URI.buildUpon().appendQueryParameter(ContactsContract.CALLER_IS_SYNCADAPTER, "true").build(); cResolver1.delete(uri4, null, null); </span>

方法二：

<span style="white-space:pre"></span>//删除通讯录public void deleteContacts(){ Uri uri = Uri.parse("content://com.android.contacts/raw_contacts");          ContentResolver cr = MainActivity.this.getContentResolver();Cursor contactsCur = cr.query(ContactsContract.Contacts.CONTENT_URI, null, null, null, null);while(contactsCur.moveToNext()){  //获取ID  String rawId = contactsCur.getString(contactsCur.getColumnIndex(ContactsContract.Contacts._ID));  //删除  String where = ContactsContract.Data._ID  + " =?";  String[] whereparams = new String[]{rawId};  getContentResolver().delete(RawContacts.CONTENT_URI.buildUpon().appendQueryParameter(ContactsContract.CALLER_IS_SYNCADAPTER,"true").build(), where, whereparams);}}
