Android - unexplained crash

I am trying to show a bitmap image inside an image view using the following code:

ImageView imageView = (ImageView) findViewById(R.id.item_picture);
byte[] decodedString = Base64.decode(temp, Base64.DEFAULT);
Bitmap decodedByte = BitmapFactory.decodeByteArray(decodedString, 0, decodedString.length); 
imageView.setImageBitmap(decodedByte);

However it keeps crashing on the last line and i dont know why.

Heres the logcat:

Here the getView code:

@Override
    public View getView(int position, View convertView, ViewGroup parent)
    {
        //make sure we have a view to work with (may have been given null)
        View itemView = convertView;

        if(itemView == null)
        {
                itemView = getLayoutInflater().inflate(R.layout.list_item, parent, false);
        }

        //Find the user to work with
        Users currentUser = myUsers.get(position);

        //Fill the view
        TextView text;
        text = (TextView) itemView.findViewById(R.id.item_name);
        text.setText(currentUser.getName());

        text = (TextView) itemView.findViewById(R.id.item_location);
        text.setText(currentUser.getLocation());

        String temp = currentUser.getPicture();

        if(!temp.equals("noPicture"))
            {
                ImageView imageView = (ImageView) findViewById(R.id.item_picture);
                byte[] decodedString = Base64.decode(temp, Base64.DEFAULT);
                Bitmap decodedByte = BitmapFactory.decodeByteArray(decodedString, 0, decodedString.length); 
                imageView.setImageBitmap(decodedByte);
        }

        return itemView;
    }

Can anyone see a reason for it crashing??

Solution

  • Replace:

    ImageView imageView = (ImageView) findViewById(R.id.item_picture);

    with:

    ImageView imageView = (ImageView) itemView.findViewById(R.id.item_picture);

    You should search for the View in your itemView, since this View doesn't exist in the Main layout, it is only visible in your ListView items, so findViewById will return null.
