ContactsContract.Contacts问题，重复(ContactsContract.Contacts issue, duplicates)

ContactsContract.Contacts问题，重复(ContactsContract.Contacts issue, duplicates)

我一直在研究这个，但我无法弄清楚。 我下载的示例应用中手机中的联系人通常是重复的，如下所示：

我很确定它与ContactsContract.Contacts有关。 我已经阅读了它，但不知道如何在我的代码中实现它。 有人可以提供帮助（或者确实有其他方式可以帮助）。 我只想让每个联系人列出一次，而不是多次。

根据http://developer.android.com/reference/android/provider/ContactsContract.Contacts.html ：

ContactsContract.Contacts Constants for the contacts table, which contains a record per aggregate of raw contacts representing the same person.

我的项目中有3个java文件，MainActivity，SelectUser和SelectUserAdapter，但我相信MainActivity是与此问题有关的文件。 可能具体这条线：

phones = getContentResolver().query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null, null, null, ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME + " ASC");

如果您需要更多代码，请告诉我。

这是我的MainActivity.java：

package com.example.chris.contactlistcustomlistview; import android.app.Activity; import android.content.ContentResolver; import android.database.Cursor; import android.graphics.Bitmap; import android.net.Uri; import android.os.AsyncTask; import android.os.Bundle; import android.provider.ContactsContract; import android.provider.MediaStore; import android.util.Log; import android.view.View; import android.widget.AdapterView; import android.widget.ListView; import android.widget.SearchView; import android.widget.Toast; import java.io.IOException; import java.util.ArrayList; import java.util.List; public class MainActivity extends Activity { // ArrayList ArrayList<SelectUser> selectUsers; List<SelectUser> temp; // Contact List ListView listView; // Cursor to load contacts list Cursor phones, email; // Pop up ContentResolver resolver; SearchView search; SelectUserAdapter adapter; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); selectUsers = new ArrayList<SelectUser>(); resolver = this.getContentResolver(); listView = (ListView) findViewById(R.id.contacts_list); phones = getContentResolver().query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null, null, null, ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME + " ASC"); // retrieves contact information LoadContact loadContact = new LoadContact(); loadContact.execute(); // let's set up our search box, search = (SearchView) findViewById(R.id.searchView); //*** setOnQueryTextListener *** search.setOnQueryTextListener(new SearchView.OnQueryTextListener() { @Override public boolean onQueryTextSubmit(String query) { // TODO Auto-generated method stub return false; } @Override public boolean onQueryTextChange(String newText) { // when the text in searchView changes, call the filter function adapter.filter(newText); return false; } }); } // Load data on background class LoadContact extends AsyncTask<Void, Void, Void> { @Override protected void onPreExecute() { super.onPreExecute(); } @Override protected Void doInBackground(Void... voids) { // Get Contact list from Phone if (phones != null) { Log.e("count", "" + phones.getCount()); if (phones.getCount() == 0) { Toast.makeText(MainActivity.this, "No contacts in your contact list.", Toast.LENGTH_LONG).show(); } while (phones.moveToNext()) { Bitmap bit_thumb = null; String id = phones.getString(phones.getColumnIndex(ContactsContract.CommonDataKinds.Phone.CONTACT_ID)); String name = phones.getString(phones.getColumnIndex(ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME)); String phoneNumber = phones.getString(phones.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER)); String EmailAddr = phones.getString(phones.getColumnIndex(ContactsContract.CommonDataKinds.Email.DATA2)); String image_thumb = phones.getString(phones.getColumnIndex(ContactsContract.CommonDataKinds.Phone.PHOTO_THUMBNAIL_URI)); try { if (image_thumb != null) { bit_thumb = MediaStore.Images.Media.getBitmap(resolver, Uri.parse(image_thumb)); } else { Log.e("No Image Thumb", "--------------"); } } catch (IOException e) { e.printStackTrace(); } //what's happening here? For every user in the phonebook, show an image, the name, number, an id and maybe a checkbox? SelectUser selectUser = new SelectUser(); selectUser.setThumb(bit_thumb); selectUser.setName(name); selectUser.setPhone(phoneNumber); selectUser.setEmail(id); selectUser.setCheckedBox(false); selectUsers.add(selectUser); } } else { Log.e("Cursor close 1", "----------------"); } //phones.close(); return null; } @Override // when DoInBackground is finished, when we have our phone number, name etc... display the results in our listview. protected void onPostExecute(Void aVoid) { super.onPostExecute(aVoid); adapter = new SelectUserAdapter(selectUsers, MainActivity.this); listView.setAdapter(adapter); // Select item on listclick listView.setOnItemClickListener(new AdapterView.OnItemClickListener() { @Override public void onItemClick(AdapterView<?> adapterView, View view, int i, long l) { Log.e("search", "here---------------- listener"); SelectUser data = selectUsers.get(i); } }); listView.setFastScrollEnabled(true); } } @Override protected void onStop() { super.onStop(); phones.close(); } }

I've been doing research on this but I can't figure it out. My contacts in my phone in a sample app I downloaded are often duplicated, like so:

I'm quite sure it has something to do with ContactsContract.Contacts. I've read up on it but don't know how to implement it in my code. Could someone help (or indeed if there's another way of doing it). I just want each contact be listed once, not multiple time.

According to http://developer.android.com/reference/android/provider/ContactsContract.Contacts.html :

ContactsContract.Contacts Constants for the contacts table, which contains a record per aggregate of raw contacts representing the same person.

I have 3 java files in my project, MainActivity, SelectUser and SelectUserAdapter, but I believe MainActivity is the one pertaining to this problem. Probably specifically this line :

phones = getContentResolver().query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null, null, null, ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME + " ASC");

If you need more code just let me know.

Here's my MainActivity.java :
