onreceive方法我想显示发件人姓名和日期和时间

Question

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 );


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

        smsList.clear();

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


        ListView smsListView = (ListView) findViewById( R.id.SMSList );
        smsListView.setAdapter( new ArrayAdapter<String>( this, android.R.layout.simple_list_item_1, smsList) );
        smsListView.setOnItemClickListener( this );

目前我使用地址栏显示短信发送者，因此会显示电话号码。我想用人名替换电话号码。我希望那个人包含它，但对于大多数短信来说它都是空的。然后，日期字段包含长值，当我想以DD.MM.YYYY格式显示它时
