Android Android Lists and Adapters (2015) Using Parcelable Data Retrieving Parcelable Data

Posted by Juan Jose

Why is no information on the items list?

After i did the Parcelable implementation, I run the project, i can see the list and the icons that there is by dafault, but i can't see the information that I retrieve from forecast IO, the first page (MainActivity) looks ok, but when I clicked on the 7 days button I just see the 8 items on the list and the 2 icons... but no info.

I debugged the parcelable data that i get from Main Activity and there is the data array info with the daily info into the array that i pass to the adapter but still not display info.

you can see my code here

In your DayAdapter.java remove the if statement: If(convertView==null) put all the code inside if and else statment together.There is no requirement for the if condition.

Sagar Suri thanks I just fixed my problems just the way you told me, i did the wrong way, sorry, i take out the values set out of the else the fixed code for the getView Method on the adapter just look like this: Thanks!!!

public View getView(int position, View convertView, ViewGroup parent) {
        ViewHolder holder;
        if(convertView == null){
            //brand new
            convertView = LayoutInflater.from(this.mContext).inflate(R.layout.daily_list_item, null);
            holder = new ViewHolder();
            holder.iconImageView = (ImageView) convertView.findViewById(R.id.iconImageView);
            holder.temperatureLabel = (TextView) convertView.findViewById(R.id.temperatureLabel);
            holder.dayLabel = (TextView) convertView.findViewById(R.id.dayLabel);
            convertView.setTag(holder);
        }else{
            holder = (ViewHolder) convertView.getTag();
        }

        Day day  = mDays[position];
        holder.iconImageView.setImageResource(day.getIconId());
        holder.temperatureLabel.setText(day.getTemperatureMax() + "");
        holder.dayLabel.setText(day.getDayOfTheWeek());
        return convertView;
    }
