</LinearLayout>

</LinearLayout>

但我的结果变成了

我怎么能解决它？

UPDATE1
我的listAdapter.java

public class ListAdapter1 extends BaseAdapter {
private LayoutInflater myInflater;
private List<SmsInformation> list;

public ListAdapter1(Context context) {
    myInflater = LayoutInflater.from(context);

}

public void setData(List<SmsInformation> list2) {
    this.list = list2;

}

@Override
public int getCount() {
    return list.size();
}

@Override
public Object getItem(int position) {
    return null;
}

@Override
public long getItemId(int position) {
    return 0;
}

@Override
public View getView(int position,View convertView,ViewGroup parent) {
    ViewHolder holder;        

    if (convertView == null) {
        if (list.get(position).getTypeOfSms().equals("send"))
            convertView     = myInflater.inflate(R.layout.raw_left,null);
        else
            convertView     = myInflater.inflate(R.layout.raw_right,null);

        holder          = new ViewHolder();
        holder.message      = (TextView) convertView.findViewById(R.id.message);
        holder.dateAndTime      = (TextView) convertView.findViewById(R.id.dataAndTime);



        convertView.setTag(holder);
    } else {
        holder = (ViewHolder) convertView.getTag();
    }

    holder.message.setText(list.get(position).getMessageContent());
    holder.dateAndTime.setText(list.get(position).geTime()+list.get(position).getDate());




    return convertView;
}

static class ViewHolder {
    TextView message;
    TextView dateAndTime;
}

}
