Question

I made a listview that has three textviews and a checkbox and put it into a BaseAdapter. What it has to do is if an item is at the ‘unread‘ status, then make its textviews BOLD. However, I encountered two problems.

1. the top item is always BOLD no matter it is read or unread.
2. If I do scrolling, then items reloaded by scrolling start to be bold

I researched about it but couldn’t find any good things for me. If anyone has an idea, would you please help me? Below is getView().

public View getView(final int position, View convertView, ViewGroup parent) {
            View view = convertView;
            ViewHolder viewHolder;

            if(convertView == null){ // check if convertView exists
                // get and inflate layout
                view = layoutInflater.inflate(R.layout.row, null);

                viewHolder = new ViewHolder();
                viewHolder.tv1 = (TextView)view.findViewById(R.id.list_callerIDname);
                viewHolder.tv2 = (TextView)view.findViewById(R.id.list_callerIDnumber);
                viewHolder.tv3 = (TextView)view.findViewById(R.id.list_messageSentTime);
                viewHolder.cb = (CheckBox)view.findViewById(R.id.checkBox1);

                // get each CheckBox into cb_array for future use
                this.cb_array[position] = (CheckBox)view.findViewById(R.id.checkBox1);

                // use it as a tag
                view.setTag(viewHolder);
            }
            else{
                viewHolder = (ViewHolder)view.getTag();
            }

            viewHolder.tv1.setText(this.callerIDnames[position]);
            viewHolder.tv2.setText(this.callerIDnumbers[position]);
            viewHolder.tv3.setText(this.messageSentTimes[position]);

            // if message is unread, then make texts bold
            if (messageRead_list[position] == false){
                viewHolder.tv1.setTypeface(viewHolder.tv1.getTypeface(), Typeface.BOLD);
                viewHolder.tv2.setTypeface(viewHolder.tv2.getTypeface(), Typeface.BOLD);
                viewHolder.tv3.setTypeface(viewHolder.tv3.getTypeface(), Typeface.BOLD);
            }

            return view;
        }

Answer 1

You will have to pass null in setTypeFace() instead of using getTypeFace().

When getTypeFace() doesn’t return null the style wont be set correctly.

// if message is unread, then make texts bold
if (messageRead_list[position] == false){
    viewHolder.tv1.setTypeface(null, Typeface.BOLD);
    viewHolder.tv2.setTypeface(null, Typeface.BOLD);
    viewHolder.tv3.setTypeface(null, Typeface.BOLD);
} else {
    viewHolder.tv1.setTypeface(null, Typeface.NORMAL);
    viewHolder.tv2.setTypeface(null, Typeface.NORMAL);
    viewHolder.tv3.setTypeface(null, Typeface.NORMAL);
}

Or you could use this directly which is what’s done when you pass null.

setTypeface(Typeface.defaultFromStyle(Typeface.BOLD));

and

setTypeface(Typeface.defaultFromStyle(Typeface.NORMAL));
