public class GetAllDatas extends Activity {

ListView lvItem;

    itemAdapter = new ArrayAdapter<String>(this, android.R.layout.simple_list_item_1,contactlist);

    btnAdd.setOnClickListener(new View.OnClickListener() { 
        public void onClick(View v) {
            readContacts();

} 

private void readContacts()

    while (cursor.moveToNext())

        if(Integer.parseInt(cursor.getString(cursor.getColumnIndex(ContactsContract.Contacts.HAS_PHONE_NUMBER))) > 0)
        {
            Cursor pCur = cr.query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI,null,ContactsContract.CommonDataKinds.Phone.CONTACT_ID +" = ?",new String[]{id}, null);
            while (pCur.moveToNext())

            pCur.close();  
        }   

int phoneNumberCount = phoneNumber.size();

// Add arraylist data to contactlist..

if(phoneNumberCount > emailCount) {

    for (int i=0; i<phoneNumberCount; i++)
      {
        if(emailCount>i)
          {
           contactlist.add(displayName +  " , " +  Ptype + " , " + phoneNumber.get(i) + " , " + Etype + " , " + emailAddress.get(i) + "\n");    
           }
        else
        {
          contactlist.add(displayName + " , " +  Ptype + " , " + phoneNumber.get(i) + " , " + " , " + "\n");
        } 
       }
    }
    else  
       {
        for (int i=0; i<emailCount; i++) 
         {
        if(phoneNumberCount>i)
          {
            contactlist.add(displayName + " , " + Ptype + " , " + phoneNumber.get(i) + " , " +  Etype + " , " + emailAddress.get(i) + "\n"); 
          }
        else
        { 
          contactlist.add(displayName + " , " + " , " + " , " + Etype + " , " + emailAddress.get(i) +  "\n");
        }
      }
    }      
    }
    Collections.sort(contactlist);
    itemAdapter.notifyDataSetChanged();
    cursor.close(); 
} 
 }

问题是，我在ListView的错误订单中获得了电话类型和电子邮件类型。这意味着我将2个号码 [Home，Mobile] 和2个电子邮件 [Home，Work] 保存到特定联系人。当我运行代码时，此联系人的ListView显示变为数字 [移动，工作] 和电子邮件 [移动，工作] 。我无法更正代码。如何正确显示ListView.Anybody知道如何调试它？

Answer 1

问题出现在你的循环中......每个项目只有一个变量，并且每次都重新设置它。

当您创建要添加到列表视图的字符串时，您只能获得通过每个循环的最后一次迭代的值。

您应该将大量字符串创建移动到这些循环中。

在循环外部启动字符串，设置联系人姓名，然后通过电话＃循环在每次迭代中添加电话号码（和类型），然后在每次迭代时将电子邮件（和类型）添加到字符串通过电子邮件循环。

修改

我认为这就是你想要的：

private void readContacts() { ContentResolver cr = getContentResolver(); Cursor cursor = cr.query(ContactsContract.Contacts.CONTENT_URI, null, null, null, null); while (cursor.moveToNext()) { displayName = ""; displayName = cursor .getString(cursor .getColumnIndex(ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME)); String id = cursor.getString(cursor .getColumnIndex(ContactsContract.Contacts._ID)); String holder = ""; holder = holder + displayName; /* Phone Number and Type */ if (Integer .parseInt(cursor.getString(cursor .getColumnIndex(ContactsContract.Contacts.HAS_PHONE_NUMBER))) > 0) { Cursor pCur = cr.query( ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null, ContactsContract.CommonDataKinds.Phone.CONTACT_ID + " = ?", new String[] { id }, null); while (pCur.moveToNext()) { contactPhoneType = pCur .getInt(pCur .getColumnIndex(ContactsContract.CommonDataKinds.Phone.TYPE)); switch (contactPhoneType) { case ContactsContract.CommonDataKinds.Phone.TYPE_HOME: holder = holder + ", Home"; break; case ContactsContract.CommonDataKinds.Phone.TYPE_WORK: holder = holder + ", Work"; break; case ContactsContract.CommonDataKinds.Phone.TYPE_MOBILE: holder = holder + ", Mobile"; break; case ContactsContract.CommonDataKinds.Phone.TYPE_OTHER: holder = holder + ", Other"; break; } holder = holder + ", " + (pCur.getString(pCur .getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER))); } pCur.close(); } /* Email */ Cursor emails = cr.query(Email.CONTENT_URI, null, Email.CONTACT_ID + " = " + id, null, null); while (emails.moveToNext()) { int contactPhoneType = emails .getInt(emails .getColumnIndex(ContactsContract.CommonDataKinds.Email.TYPE)); switch (contactPhoneType) { case ContactsContract.CommonDataKinds.Email.TYPE_HOME: holder = holder + ", Home"; break; case ContactsContract.CommonDataKinds.Email.TYPE_WORK: holder = holder + ", Work"; break; case ContactsContract.CommonDataKinds.Email.TYPE_MOBILE: holder = holder + ", Mobile"; break; case ContactsContract.CommonDataKinds.Email.TYPE_OTHER: holder = holder + ", Other"; break; } holder = holder + ", " + (emails .getString(emails .getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER))); } emails.close(); contactlist.add(holder); } Collections.sort(contactlist); itemAdapter.notifyDataSetChanged(); cursor.close(); }

联系方式来了不正确的订单
