Question

I have a list view in which I add items dynamically. I want that some items ( of my choice) should align to the left hand side and some to the right hand side. Is this thing possible with the ListView of Android??

//Adapter

if (convertView == null) {
                holder = new EventViewHolder();
                if (type == 1) {
                    convertView = inflater.inflate(
                            R.layout.multi_line_list_item, null);
                    holder.mtvMessage = (TextView) convertView
                    .findViewById(R.id.tvMessage);
                    holder.mtvMessage.setGravity(Gravity.LEFT);
                    holder.mtvMessage.setBackgroundResource(R.drawable.chatbluebox);
                    convertView.setTag(holder);
                }else{
                    convertView = inflater.inflate(
                            R.layout.multi_line_list_item, null);
                    holder.mtvMessage = (TextView) convertView
                    .findViewById(R.id.tvMessage);
                    holder.mtvMessage.setGravity(Gravity.RIGHT);
                    holder.mtvMessage.setBackgroundResource(R.drawable.chatgreenbox);
                    convertView.setTag(holder);

            }

Please let me know if it can be done and suggest me a good solution?

Answer 1

Use following.

adapter.notifyDataSetChanged();

And then

listView.setSelection(items.size()-1);

For gravity You need to set gravity dynamically in your getview() method.

FOr example :-

textview1.setGravity(Gravity.RIGHT);
