Multiple SeekBars in Adapter, only last SeekBar updates

Question

I have a ListView which has a SeekBar in each row. the size of the list and therefore the number of SeekBars will vary.

I've set a SeekBar.OnSeekBarChangeListener and from that i update a TextView based on the integer the SeekBar is displaying.

The problem is that only the last SeekBar in the list seems to update from the SeekBar.OnSeekBarChangeListener.

How can i make all of the SeekBars work?

Thanks in advance.

        private final Context context;
        private final ArrayList<?> list;            

        public MySimpleArrayAdapter(Context context, ArrayList<?> list) {

            super(context, R.layout.monitoringrowlayout);
            Log.e(TAG, "inside adapter constructor");
            this.context = context;
            this.list = list;               

        }

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

            LayoutInflater inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);

            sb.setOnSeekBarChangeListener(customSeekBarListener);

};    

private void upDateTextBox(int progress){

    rating.setText(String.valueOf(progress));       

}

Answer 1

This was obviously going to happen.

Since sb will always be the "last" SeekBar, and rating will be always the "last" rating TextView.

Change your code:

    private class MySimpleArrayAdapter extends ArrayAdapter<String> {
    private final Context context;
    private final ArrayList<?> list;


    public MySimpleArrayAdapter(Context context, ArrayList<?> list) {

        super(context, R.layout.monitoringrowlayout);
        Log.e(TAG, "inside adapter constructor");
        this.context = context;
        this.list = list;


    }

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


        LayoutInflater inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);

        View rowView = inflater.inflate(R.layout.monitoringrowlayout, parent, false);

        final int pos = position;


        Log.e(TAG, "list size in adapter = " + list.size());



        String record = list.get(position).toString();
        rowView.setTag(record);
        String[] itemsInRecord = record.split(",");
        Log.e(TAG, "itemin record = " + itemsInRecord.length);
        String[] recordItem = new String[itemsInRecord.length];

        for (int x = 0; x < itemsInRecord.length; x++) {

            recordItem[x] = itemsInRecord[x];

            Log.e(TAG, "recordItem[x]" + x + " " +recordItem[x] );

        }

        recordItem[0] = recordItem[0].replace('[', ' ').trim();
        recordItem[3] = recordItem[3].replace(']', ' ').trim();

        TextView description =  (TextView) rowView.findViewById(R.id.rowmonitoringdescription);
        description.setText(recordItem[1]);



        SeekBar sb = (SeekBar)rowView.findViewById(R.id.seekbarmonitoring);
        sb.setOnSeekBarChangeListener(customSeekBarListener);
        sb.setTag(rowView.findViewById(R.id.rowmonitoringrating));






        return rowView;




    }

    @Override
    public int getCount() {
        return this.list.size();
    }

}// end of adapter class



    private SeekBar.OnSeekBarChangeListener customSeekBarListener = new SeekBar.OnSeekBarChangeListener() {

        @Override
        public void onStopTrackingTouch(SeekBar seekBar) {
            // TODO Auto-generated method stub

        }

        @Override
        public void onStartTrackingTouch(SeekBar seekBar) {
            // TODO Auto-generated method stub

        }

        @Override
        public void onProgressChanged(SeekBar seekBar, int progress, boolean fromUser) {

            upDateTextBox((TextView) seekBar.getTag(), progress);

        }
    };


    private void upDateTextBox(TextView tv, int progress){

        tv.setText(String.valueOf(progress));


    }
}
