Question

我的自定义列表视图存在某种独特的问题，我无法追踪问题所在。自定义列表视图用于我正在创建的聊天应用程序，其中我使用用户输入的消息动态添加文本视图。添加了每个文本视图后，列表视图将移动到屏幕的左侧，文本视图 enter image description here 在左侧被切割，我搜索了很多可能是原因但不能找到任何人，有人可以帮我解决这个问题吗？图像显示每个条目在右侧增加的间隙。这是xml代码

这是我的适配器 `

public class ChatMessageAdapter extends  ArrayAdapter<Chat>
{
        List<Chat>listmsg=new ArrayList<Chat>(); 
        Activity context;
        Bitmap bitmapfriend,bitmapuser;
        public ChatMessageAdapter(Activity context,List<Chat> listmsg, Bitmap friendimage, Bitmap userimage) 
        {
            super(context, R.layout.list_row_layout_even, listmsg);
            this.listmsg=listmsg;
            this.context=context;
            this.bitmapfriend=friendimage;
            this.bitmapuser=userimage;
        }


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

        try 
        {
            try 
            {
        LayoutInflater inflater = context.getLayoutInflater();

        String type=listmsg.get(position).getType();

        if(type.contentEquals("even"))
        {
            convertView = inflater.inflate(R.layout.list_row_layout_even, parent, false);
            TextView textLabel = (TextView) convertView.findViewById(R.id.text);
            textLabel.setText(listmsg.get(position).getMessageSpannable());
            ImageView image=(ImageView) convertView.findViewById(R.id.rightProfilePic);
            if (bitmapuser==null) 
            {

            }
            else
            {
            image.setImageBitmap(bitmapuser);
            }   
        }
        else if(type.contentEquals("odd"))
        {
            convertView = inflater.inflate(R.layout.list_row_layout_odd, parent, false);
            TextView textLabel = (TextView) convertView.findViewById(R.id.text);
            textLabel.setText(listmsg.get(position).getMessageSpannable());
            ImageView image=(ImageView) convertView.findViewById(R.id.leftProfilePic);
            image.setImageBitmap(bitmapfriend);
        }           
            }
            catch (Exception e) 
            {
                throw new IOException("Error connecting");
            }
        } 
        catch (Exception e) 
        {

        }       
        return (convertView);
    }

} `
