카카오톡과 비슷한 채팅UI를 만드는중에 안되는 부분이 있어서 질문합니다..
기존 소스
public class AwesomeAdapter extends BaseAdapter{
private Context mContext;
private ArrayList<Message> mMessages;
public AwesomeAdapter(Context context, ArrayList<Message> messages) {
super();
this.mContext = context;
this.mMessages = messages;
}
@Override
public int getCount() {
return mMessages.size();
}
@Override
public Object getItem(int position) {
return mMessages.get(position);
}

public View getView(int position, View convertView, ViewGroup parent) {
Message message = (Message) this.getItem(position);

holder = (ViewHolder) convertView.getTag();
holder.message.setText(message.getMessage());

이처럼 바꾸었는데 기존의 XML을 사용할 경우엔 직접보내기한 내용은 우측정렬로 나오고 미리 설정해놓은 내용은 좌측 정렬이 되는데, 바꾸면서 전부 좌측정렬로 되네요... 어딜 수정해야할지..
sms_row.xml부분
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical" >
<TextView
android:id="@+id/message_text"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_margin="5sp"
android:textSize="20sp" />
</LinearLayout>
