Question

I asked this question yesterday, but I wrote it far more complicated than I think this problem is. I am very confused and I found some very similar questions here, but neither of them solved my problem. So I have a listview, every listview contains an image, a textview and an edittext, but only the edittext is important.
If I click on the textview, I want to log the content of it for testing. My problem is if the user changes it then after the change I log the same thing. So changing it in the emulator and not using setText, it does nothing. I have a database, in every of the listview there is an edittext (holder.quant).

class MyAdapter extends ArrayAdapter
{

    LayoutInflater inflat;
    ViewHolder holder;
    public MyAdapter(Context context, int textViewResourceId,
            ArrayList<EachRow> objects) 
    {

        super(context, textViewResourceId, objects);
        // TODO Auto-generated constructor stub
        inflat=LayoutInflater.from(context);
    }
    @Override
    public View getView(int position, View convertView, ViewGroup parent) {
        // TODO Auto-generated method stub

        if(convertView==null)
        {
            convertView=inflat.inflate(R.layout.row_checkox, null);
            holder=new ViewHolder();
            holder.textView=(TextView)convertView.findViewById(R.id.textView111);
            holder.image=(ImageView)convertView.findViewById(R.id.imageView111);



            holder.quant = (EditText)convertView.findViewById(R.id.quantity);


            holder.image.setOnClickListener(CustomList.this);
            convertView.setTag(holder);
        }
        holder=(ViewHolder) convertView.getTag();



        holder.textView.setOnClickListener(new View.OnClickListener() {


          @Override
            public void onClick(View v) {

                 TextView tv = (TextView) v ;
            String text_of_clicked_textview = tv.getText().toString();

             final String[] ddata = text_of_clicked_textview.split(" "); //split the result using the spaces (so you could obtain the name, hotness and the other string you use)


                final long yy = Long.parseLong(ddata[0]);



                info.open();
                info.updateQuan(yy, holder.quant.getText().toString());
                Log.i("tagitagi", holder.quant.getText().toString());
                info.close();
            }
        });



        EachRow row= getItem(position);
        EachRow row2= getItem2(position);
        holder.quant.setText(row2.text);

        holder.textView.setText(row.text);
        NullPointerException
        holder.image.setTag(position);
        holder.quant.setTag(position);

        return convertView;
    }

    @Override
    public EachRow getItem(int position) {
        // TODO Auto-generated method stub
        return list.get(position);
    }
    public EachRow getItem2(int position) {
        // TODO Auto-generated method stub
        return list2.get(position);
    }

    private class ViewHolder
    {
        TextView textView;
        ImageView image;
        EditText quant;


    }
}

private class EachRow
{
    String text;
    boolean checkBool;
}

I tried addTextChangedListener, but it gives me an error when I use settext. So what is the problem?

Thanks in advance!

Answer 1

I managed to figure out how can I make it work. The holder.quant.gettext().toString does not work, even if I click on the textview of one of the rows I cannot log the content of the textview. The holder somehow blocks it, I will always log the same textview…

So I needed to create a new method:

public String getTextOfSelectedRow(int position) {
                       return list.get(position).text;
        }

The list contains the rows, the .text comes from the method:

private class EachRow
    {
        String text;
        boolean checkBool;
    }

and the definition of the holder:

 public View getView(final int position, View convertView, ViewGroup parent) {
            // TODO Auto-generated method stub

            if(convertView==null)
            {
                convertView=inflat.inflate(R.layout.row_checkox, null);
                holder=new ViewHolder();
                holder.textView=(TextView)convertView.findViewById(R.id.textView111);
                holder.image=(ImageView)convertView.findViewById(R.id.imageView111);

                holder.quant = (EditText)convertView.findViewById(R.id.quantity);
           holder.button = (Button)convertView.findViewById(R.id.dialogQuan);
                holder.image.setOnClickListener(CustomList.this);
                convertView.setTag(holder);
            }
            holder=(ViewHolder) convertView.getTag();



            holder.button.setOnClickListener(new View.OnClickListener() {....

So after this the onClick method:

kmultip = getTextOfSelectedRow(position).toString();

So with this I can refer to the holder.quant or holder.textview or anything that is in a row. I still do not know why the simple holder.quant.getText().toString does not work, but with this, so refering to the position of a row will makes it work.
