ListView Rowlayout in a own coded Chat

问题

What I'm trying to do

I'm trying to create a chat which has to diffrent row's. For every row I made a own layout file, but the problem is that the layoutfile of one row dosn't fit the screen.

Question

What do I need to change in the row layout that it fits like it should. You'll find the code and also a printscreen of what I'm trying.

ListAdapter public class ChatListAdapter extends BaseAdapter {

            private ArrayList<String> ContentList;
            private ArrayList<Integer> ChatUserList;

            private static LayoutInflater inflater = null;

            public ChatListAdapter(Activity activity, ArrayList<String> _ContentList,
                                   ArrayList<Integer> _ChatUserList) {
                        ContentList = _ContentList;
                        ChatUserList = _ChatUserList;
                        inflater = (LayoutInflater) activity
                                               .getSystemService(Context.LAYOUT_INFLATER_SERVICE);

            }

            public int getCount() {
                        return ContentList.size();
            }

            public Object getItem(int position) {
                        return position;
            }

            public long getItemId(int position) {
                        return position;
            }

            public View getView(int position, View convertView, ViewGroup parent) {
                        View vi = convertView;
                        TextView tv_text;
                        TextView tv_date;

                        SimpleDateFormat sdf = new SimpleDateFormat("HH:mm");

                        if (ChatUserList.get(position) == 1) {
                                   // I'm RECIVER -> Message is left align
                                   vi = inflater.inflate(R.layout.rowlayout_leftalign, null);
                                   tv_text = (TextView) vi.findViewById(R.id.tv_chat_leftalign);
                                   tv_date = (TextView) vi.findViewById(R.id.tv_chat_leftalign_date);
                        } else {
                                   // I'm SENDER -> Message is right align
                                   vi = inflater.inflate(R.layout.rowlayout_rightalign, null);
                                   tv_text = (TextView) vi.findViewById(R.id.tv_chat_rightalign);
                                   tv_date = (TextView) vi.findViewById(R.id.tv_chat_rightalign_date);
                        }

                        tv_date.setText(sdf.format(new Date()));
                        tv_text.setText(ContentList.get(position));
                        tv_text.setMaxWidth(((Chat.display.getWidth() / 4) * 3));

                        return vi;
            }

回答1:

for both XML add android:layout_width="fill_parent" and android:layout_height="wrap_content" like followings

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
            android:background="@android:color/transparent" 
            android:layout_height="wrap_content"
            android:layout_width="fill_parent" >

and so on...
