如何從聯繫人編號中讀取聯繫人姓名？

Question

我想在列表視圖中顯示聯繫人編號以及聯繫人姓名。 我做...：

public String DisplayName(String number) { 
    Uri uri = Uri.withAppendedPath(
      ContactsContract.PhoneLookup.CONTENT_FILTER_URI, 
      Uri.encode(number)); 
    String name = "?"; 

    ContentResolver contentResolver = getContentResolver(); 
    Cursor contactLookup = contentResolver.query(uri, new String[] { 
      BaseColumns._ID, ContactsContract.PhoneLookup.DISPLAY_NAME }, 
      null, null, null); 

    try { 
     if (contactLookup != null && contactLookup.getCount() > 0) { 
      contactLookup.moveToNext(); 
      name = contactLookup.getString(contactLookup 
        .getColumnIndex(ContactsContract.Data.DISPLAY_NAME)); 
      // String contactId = 
      // contactLookup.getString(contactLookup.getColumnIndex(BaseColumns._ID)); 
     } 
    } finally { 
     if (contactLookup != null) { 
      contactLookup.close(); 
     } 
    } 

    return name; 
} 

，但我的應用程序不斷強制關閉，我不知道爲什麼？我已包括許可也... 「」

任何猜測？爲什麼

Answer 1

使用此2種方法：

/* 
* Returns contact's id 
*/ 
private String getContactId(String phoneNumber, Context context) { 
    ContentResolver mResolver = context.getContentResolver(); 

    Uri uri = Uri.withAppendedPath(PhoneLookup.CONTENT_FILTER_URI, 
      Uri.encode(phoneNumber)); 

    Cursor cursor = mResolver.query(uri, new String[] { 
      PhoneLookup.DISPLAY_NAME, PhoneLookup._ID }, null, null, null); 

    String contactId = ""; 

    if (cursor.moveToFirst()) { 
     do { 
      contactId = cursor.getString(cursor 
        .getColumnIndex(PhoneLookup._ID)); 
     } while (cursor.moveToNext()); 
    } 

    cursor.close(); 
    cursor = null; 
    return contactId; 
} 

/* 
* Returns contact's name 
*/ 
private String getContactName(String contactId, Context context) { 

    String[] projection = new String[] { Contacts.DISPLAY_NAME }; 
    Cursor cursor = mResolver.query(Contacts.CONTENT_URI, projection, 
      Contacts._ID + "=?", new String[] { contactId }, null); 
    String name = ""; 
    if (cursor.moveToFirst()) { 
     name = cursor.getString(0); 
    } 

    cursor.close(); 
    cursor = null; 
    return name; 
}

使用下面的代碼：

public void readContacts(){ 
    ContentResolver cr = parent.getContentResolver(); 
    Cursor cur = cr.query(ContactsContract.Contacts.CONTENT_URI, 
      null, null, null, null); 

    if (cur.getCount() > 0) { 
     while (cur.moveToNext()) { 
      Contact tempcontact=new Contact(); 
      contactsList.add(tempcontact); 
      String id=cur.getString(cur.getColumnIndex(ContactsContract.Contacts._ID)); 
      String name=cur.getString(cur.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME)); 
      tempcontact.setId(cur.getString(cur.getColumnIndex(ContactsContract.Contacts._ID))); 
      tempcontact.setName(name); 
      if (Integer.parseInt(cur.getString(cur.getColumnIndex(ContactsContract.Contacts.HAS_PHONE_NUMBER))) > 0) { 
       Log.e("DATA","name : " + name + ", ID : " + id); 

       // get the phone number 
       Cursor pCur = cr.query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI,null, 
             ContactsContract.CommonDataKinds.Phone.CONTACT_ID +" = ?", 
             new String[]{id}, null); 
       while (pCur.moveToNext()) { 
        if(pCur.getString(
          pCur.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER))!=null) 
        { 
        tempcontact.getPhonenumber().add(pCur.getString(
          pCur.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER))); 
        } 
        // System.out.println("phone" + phone); 
        // Log.e("phone",phone); 
       } 
       pCur.close(); 


       // get email and type 

       Cursor emailCur = cr.query(
         ContactsContract.CommonDataKinds.Email.CONTENT_URI, 
         null, 
         ContactsContract.CommonDataKinds.Email.CONTACT_ID + " = ?", 
         new String[]{id}, null); 
       while (emailCur.moveToNext()) { 
        // This would allow you get several email addresses

        tempcontact.getEmail().add(emailCur.getString(
           emailCur.getColumnIndex(ContactsContract.CommonDataKinds.Email.DATA))); 
        String emailType = emailCur.getString(
           emailCur.getColumnIndex(ContactsContract.CommonDataKinds.Email.TYPE)); 

        Log.e("Data","Email " + email + " Email Type : " + emailType); 
       } 
       emailCur.close(); 


       String addrWhere = ContactsContract.Data.CONTACT_ID + " = ? AND " + ContactsContract.Data.MIMETYPE + " = ?"; 
       String[] addrWhereParams = new String[]{id,

        tempcontact.setCountry((addrCur.getString(
           addrCur.getColumnIndex(ContactsContract.CommonDataKinds.StructuredPostal.COUNTRY)))); 
        tempcontact.setType(addrCur.getString(
           addrCur.getColumnIndex(ContactsContract.CommonDataKinds.StructuredPostal.TYPE)));

Cursor phones= getContentResolver().query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null,null,null, null); 
while (phones.moveToNext()) 
{ 

    String phoneNumber = phones.getString(phones.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER)); 

} 
phones.close();
