Question

所以基本上我有一个删除手机联系人的功能：

String[] args = new String[]{number};

    try {

        ArrayList ops = new ArrayList();
        // if id is raw contact id
        ops.add(ContentProviderOperation.newDelete(ContactsContract.RawContacts.CONTENT_URI).withSelection(ContactsContract.RawContacts._ID + "=?", args).build());
        // if id is contact id
       // ops.add(ContentProviderOperation.newDelete(ContactsContract.RawContacts.CONTENT_URI).withSelection(ContactsContract.RawContacts.CONTACT_ID + "=?", args).build());
        getContentResolver().applyBatch(ContactsContract.AUTHORITY, ops);
        Toast.makeText(this, "Contact Deleted", Toast.LENGTH_SHORT).show();


    } catch (Exception e) {

        Log.e("$$$$", "ERRORDELETE#133");
    }

我尝试了两种选择，如果原始联系人或联系人ID，两者都没有工作/

当我运行APP并且该功能激活了“已删除的联系人”＃39;显示并在日志中：

05-24 15:40:16.444 6540-6540/com.assistme.meirovichomer.assistme E/ViewRootImpl: sendUserActionEvent() mView == null
05-24 15:40:16.464 6540-6679/com.assistme.meirovichomer.assistme V/RenderScript: Application requested CPU execution

我不确定我是否只是不理解日志或者我错过了什么，但是当我在电话上输入联系人列表时，联系人仍然没有，因此没有被删除。很想得到一些帮助，非常感谢您提前！

试试这个。

删除课程。

public static void deleteContact(ContentResolver contactHelper, String 
number) {
ArrayList<ContentProviderOperation> ops = new 
ArrayList<ContentProviderOperation>();
String[] args = new String[] { String.valueOf(getContactID(contactHelper, 
number))};
ops.add(ContentProviderOperatio.newDelete(RawContacts.CONTENT_URI).withSelecti
  on(RawContacts.CONTACT_ID + "=?", args).build());
 try {
  contactHelper.applyBatch(ContactsContract.AUTHORITY, ops);
  } catch (RemoteException e) {
  e.printStackTrace();
 } catch (OperationApplicationException e) {
e.printStackTrace();
}
}

和getid class

private static long getContactID(ContentResolver contactHelper,String 
number) {
Uri contactUri = Uri.withAppendedPath(PhoneLookup.CONTENT_FILTER_URI, 
Uri.encode(number));
String[] projection = { PhoneLookup._ID };
Cursor cursor = null;
try {
cursor = contactHelper.query(contactUri, projection, null, null,null);
if (cursor.moveToFirst()) {
int personID = cursor.getColumnIndex(PhoneLookup._ID);
return cursor.getLong(personID);
}
return -1;
} catch (Exception e) {
e.printStackTrace();
} finally {
if (cursor != null) {
cursor.close();
cursor = null;
}
}
return -1;
}
