通过电话号码获取正确的联系人姓名

Question

我试图从电话号码中获取正确的联系人姓名以将其显示为ListView。

但我正在逐渐每次只能在同一联系人姓名所有的电话号码......

这里是我的代码：

private String getContactName(String string){ 
    String name=null; 

    ContentResolver cr=getContentResolver(); 
    Cursor cur=cr.query(ContactsContract.Contacts.CONTENT_URI,null,null,null,null); 

    if(cur.getCount()>0){ 
     while(cur.moveToNext()){ 
      String id=cur.getString(cur.getColumnIndex(ContactsContract.Contacts.HAS_PHONE_NUMBER)); 
      name=cur.getString(cur.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME)); 
     } 

    } 
    return name; 
} 


public void onClick(View v) 
{ 
    ContentResolver contentResolver=getContentResolver(); 
    Cursor cursor=contentResolver.query(Uri.parse("content://sms/inbox"),null,null,null,null); 

    int indexBody=cursor.getColumnIndex(SmsReceiver.BODY); 
    int indexAddr=cursor.getColumnIndex(SmsReceiver.ADDRESS); 

    // int indexAddr = Integer.parseInt(getContactName(Integer.toString(cursor.getColumnIndex(SmsReceiver.ADDRESS)))); 

    //getContactName(Integer.toString(indexAddr)); 
    //// 

    if(indexBody<0||!cursor.moveToFirst())return; 

    smsList.clear(); 

    do 
    { 
     //String str = "Sender: " + cursor.getString(indexAddr) + "\n" + cursor.getString(indexBody); 
     String str="Sender: "+getContactName(cursor.getString(indexAddr))+"\n"+cursor.getString(indexBody); 
     smsList.add(str); 
    } 
    while(cursor.moveToNext()); 


    ListView smsListView=(ListView)findViewById(R.id.SMSList); 
    registerForContextMenu(smsListView); 

    smsListView.setAdapter(new ArrayAdapter<String>(this,android.R.layout.simple_list_item_1,smsList)); 
    smsListView.setOnItemClickListener(this); 
} 

我找不到哪里是我的错误...并且只为所有发件人号码获取相同的名称。

谢谢

这里是你的函数的正确代码。

private String getContactName(String phoneNumber) 
{ 
    String name = null; 
    ContentResolver cr = getContentResolver(); 
    Cursor cur = cr.query(Uri.withAppendedPath(PhoneLookup.CONTENT_FILTER_URI, 
     Uri.encode(phoneNumber)), new String[]{ PhoneLookup.DISPLAY_NAME }, null, null, null); 
    if(cur != null){ 
     try{ 
      if(cur.getCount() > 0){ 
       if(cur.moveToFirst()){ 
        name = cur.getString(cur.getColumnIndex(PhoneLookup.DISPLAY_NAME)); 
       } 
      } 
     } 
     finally{ 
      cur.close(); 
     } 
    } 
    return name; 
}
