Android Multiple EditText fields in a ListAdapter

Question

I have a screen (see picture) that is populated by a GridView using a custom extension of BaseAdapter.

When the user enters some text into the EditText fields, the text

I would again preface this, as in the other answer, by saying I wouldn't implement it this way. You're doing scary stuff. Carrying lots of references around. However, I think this should help:

Map<EditText, MyTextWatcher> watchers = new HashMap<EditText, MyTextWatcher>();

public View getView(int position, View convertView, ViewGroup parent)
{
    View MyView = convertView;
    if (MyView == null)
    {
        LayoutInflater li = getLayoutInflater();
        MyView = li.inflate(R.layout.shape, null);
    }

    EditText textbox = (EditText) MyView.findViewById(R.id.shape_edittext);

    textbox.setText(strings[position]);
    MyTextWatcher myTextWatcher = watchers.get(textbox);

    if(myTextWatcher == null)
    {
        myTextWatcher = new MyTextWatcher(position, textbox);
        watchers.put(textbox, myTextWatcher);
    }

    myTextWatcher.setIndex(position);

    ImageView image = (ImageView) MyView.findViewById(R.id.shape_image);
    image.setBackgroundResource(images[position]);

    TextView text = (TextView) MyView.findViewById(R.id.shape_text);
    text.setText("Seq:");

    return MyView;
}

The problem here is that you created the TextWatcher, added it to an EditText, but then kept a reference to it in a list by position, so the references between EditText and the TextWatcher were broken.

This solution assumes that 'equals' for EditText will do an object instance compare and not a value compare. If that is NOT the case, you'd need to keep a reference to all EditText instances, and do an '==' compare to each and find a match.

I think there are safer ways to do this, but give it a shot.
