Question

我项目中的手机类型和电子邮件类型存在一些问题。我使用2.1平台，在添加电话类型和电子邮件类型之前我的项目没有问题，在我尝试使用这些手机类型和电子邮件类型后要运行该项目，它会打开一个消息框并显示应用程序已停止并强制关闭。我的xml文件有一个Button和ListView。我正在使用此代码。

码

 public class GetAllDatas extends Activity {

ListView lvItem;
private Button btnAdd;
String Ptype, Etype;
int contactPhoneType;

String displayName="", emailAddress="", phoneNumber="";
ArrayList<String> contactlist=new ArrayList<String>(); 
ArrayAdapter<String> itemAdapter;

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);

    lvItem = (ListView)this.findViewById(R.id.lvitems); 
    btnAdd = (Button)this.findViewById(R.id.btnAddItem);

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

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

} 

private void readContacts()
{
    ContentResolver cr =getContentResolver();
    Cursor cursor = cr.query(ContactsContract.Contacts.CONTENT_URI, null, null, null, null);


    while (cursor.moveToNext()) 
    {
        displayName  = "" ;
        ArrayList<String> phoneNumber  = new ArrayList<String>();
        ArrayList<String> emailAddress  = new ArrayList<String>();

        displayName = cursor.getString(cursor.getColumnIndex(ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME));       
        String id = cursor.getString(cursor.getColumnIndex(ContactsContract.Contacts._ID));

        /*                   Email                   */ 

        Cursor emails = cr.query(Email.CONTENT_URI,null,Email.CONTACT_ID + " = " + id, null, null);
        while (emails.moveToNext()) 
        { 
            emailAddress.add(emails.getString(emails.getColumnIndex(Email.DATA)));

        } 

         contactPhoneType = emails.getInt(emails.getColumnIndex(ContactsContract.CommonDataKinds.Phone.TYPE));

        switch(contactPhoneType){
        case ContactsContract.CommonDataKinds.Phone.TYPE_HOME: 
        Etype = "Home";
        break;

        }


        emails.close(); 


      /*            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()) 
            {
                 phoneNumber.add(pCur.getString(pCur.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER)));                               
           }

            contactPhoneType = pCur.getInt(pCur.getColumnIndex(ContactsContract.CommonDataKinds.Phone.TYPE));


           switch(contactPhoneType){
           case ContactsContract.CommonDataKinds.Phone.TYPE_HOME: 
           Ptype = "Home";
           break;

           }


            pCur.close();  
        }   

int phoneNumberCount = phoneNumber.size();
int emailCount = emailAddress.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"); 
          }

        }
      }
    }      
    }
    Collections.sort(contactlist);
    itemAdapter.notifyDataSetChanged();
    cursor.close(); 
}

}

Answer 1

可能是这一行：

while (cursor.moveToNext())

对我来说，看起来你在读取第一个光标位置之前移动了光标，并且你得到了一个CursorIndexOOB例子。

尝试使用do-while循环，看看是否有帮助。

另外，请检查您的应用程序是否有权阅读联系人数据。

uses-permission android:name="android.permission.READ_CONTACTS"

Answer 2

我的代码中出现错误。将光标移动到最后一条记录（p {{{}}循环超出最后一条记录后的pCur.moveToNext（））后，您正在检查phoneType和emailtype。您需要在while循环内检查它，而不是在if。之后。更改以下内容：

while

也对emailType进行相同的更正。

Answer 3

看起来问题是索引

android.database.CursorIndexOutOfBoundsException: Index 1 requested, with a size of 1

获取Phone.TYPE可以根据此http://www.vtgroup.com/#ContactsContract

尝试以下代码

    //  Get all phone numbers.
    //
    Cursor phones = cr.query(Phone.CONTENT_URI, null,
        Phone.CONTACT_ID + " = " + contactId, null, null);
    while (phones.moveToNext()) {
        String number = phones.getString(phones.getColumnIndex(Phone.NUMBER));
        int type = phones.getInt(phones.getColumnIndex(Phone.TYPE));
        switch (type) {
            case Phone.TYPE_HOME:
                // do something with the Home number here...
                break;
            case Phone.TYPE_MOBILE:
                // do something with the Mobile number here...
                break;
            case Phone.TYPE_WORK:
                // do something with the Work number here...
                break;
            }
    }
    phones.close();

Answer 4

正如Dheeresh所说，你必须改变这种状况

手机类型和电子邮件类型不起作用？
