【问题描述】：

当我在手机中查看我的联系人时，我也会看到那些拥有 whatsapp 帐户的人的 whatsapp 号码。我想要做的是过滤我的联系人列表并显示与 whatsapp 同步的号码。我已成功检索所有与它关联但不显示whatsappaccount的联系人ID，号码和帐户。仅显示关联的google帐户。有没有办法从本地电话簿本身获取whatsapp联系人？我使用了以下代码：

ContentResolver cr1 = getContentResolver();
Cursor cur = cr1.query(ContactsContract.Contacts.CONTENT_URI, null, null, null, null);
    if (cur.getCount() > 0) 
    
        while (cur.moveToNext()) 
        
            String id = cur.getString(cur.getColumnIndex(ContactsContract.Contacts._ID));
            String name = cur.getString(cur.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME));
            if (Integer.parseInt(cur.getString(cur.getColumnIndex(ContactsContract.Contacts.HAS_PHONE_NUMBER))) > 0) 
            
                Cursor pCur = cr1.query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null, ContactsContract.CommonDataKinds.Phone.CONTACT_ID + " = ?", new String[]  id , null);
                while (pCur.moveToNext()) 
                
                    //phoneContactList.add(name);
                    Log.i("Contact List", name);
                    Log.i("Contact List", id);
                    
                    getContactAccount(id,cr1);
                
                pCur.close();
            
        
    


public void getContactAccount(String id,ContentResolver contentResolver)
        Cursor cursor = null;
        try 
             cursor = contentResolver.query(ContactsContract.RawContacts.CONTENT_URI,
                     new String[]ContactsContract.RawContacts.ACCOUNT_NAME, ContactsContract.RawContacts.ACCOUNT_TYPE,
                     ContactsContract.RawContacts.CONTACT_ID +"=?",
                     new String[]String.valueOf(id),
                     null);
             
            if (cursor != null && cursor.getCount() >0)
                cursor.moveToFirst();
                System.out.println("Account name is"+cursor.getString(cursor.getColumnIndex(ContactsContract.RawContacts.ACCOUNT_NAME)));
                System.out.println("Account type is"+cursor.getString(cursor.getColumnIndex(ContactsContract.RawContacts.ACCOUNT_TYPE)));
                cursor.close();
            
         catch (Exception e) 
            System.out.println(""+this.getClass().getName()+","+ e.getMessage());
         finally
          cursor.close();

试试这个***.com/questions/35448250/…它只读联系人谁在whatsapp帐户...

【参考方案1】：

使用以下代码从电话簿中获取具有相关 WhatsApp 号码的 WhatsApp 联系人：

private void displayWhatsAppContacts() 

    final String[] projection = 
            ContactsContract.Data.CONTACT_ID,
            ContactsContract.Data.DISPLAY_NAME,
            ContactsContract.Data.MIMETYPE,
            "account_type",
            ContactsContract.Data.DATA3,
    ;

    final String selection = ContactsContract.Data.MIMETYPE + " =? and account_type=?";
    final String[] selectionArgs = 
            "vnd.android.cursor.item/vnd.com.whatsapp.profile",
            "com.whatsapp"
    ;

    ContentResolver cr = getContentResolver();
    Cursor c = cr.query(
            ContactsContract.Data.CONTENT_URI,
            projection,
            selection,
            selectionArgs,
            null);

    while (c.moveToNext()) 
        String id = c.getString(c.getColumnIndex(ContactsContract.Data.CONTACT_ID));
        String number = c.getString(c.getColumnIndex(ContactsContract.Data.DATA3));
        String name = c.getString(c.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME));

        Log.v("WhatsApp", "name " +name + " - number - "+number);

    
    Log.v("WhatsApp", "Total WhatsApp Contacts: " + c.getCount());
    c.close();

如何获取联系人图片？

我必须检查一下，尝试通过调试检查光标中的数据。

【参考方案2】：

The MIME type for whatsapp is:  "vnd.android.cursor.item/vnd.com.whatsapp.profile"

使用以下代码：

public class MainActivity extends ActionBarActivity

    if (savedInstanceState == null)

                .add(R.id.container, new PlaceholderFragment()).commit();
    


@Override
public boolean onCreateOptionsMenu(Menu menu) 

    // Inflate the menu; this adds items to the action bar if it is present.
    getMenuInflater().inflate(R.menu.main, menu);
    return true;


@Override
public boolean onOptionsItemSelected(MenuItem item) 
    // Handle action bar item clicks here. The action bar will
    // automatically handle clicks on the Home/Up button, so long
    // as you specify a parent activity in AndroidManifest.xml.
    int id = item.getItemId();
    if (id == R.id.action_settings) 
        return true;
    
    return super.onOptionsItemSelected(item);
