Hello Mark,
I have been trying to implement the same functionality as Moazzam.
Specifically, I want each row in my list to have a "delete" (in my
case a process kill) button.
I read carefully your very good tutorials on lists, and tried to
follow the approach you describe in tutorial #5 (see the code below).
The result is as follows:
1) Each row does have a "kill" button
2) The first row is always blank (except for the "kill" button
3) On the "kill" button in the first row is active, i.e. performs the
required action
4) When clicking on the "kill" button in the first row, the item at
the bottom of the screen (the last visible item) is "killed"
a) I have not been able to wire all buttons
b) The button which is wired does not act on the desired item because
the value of the "position" parameter returned by getView.
I would appreciate your thoughts (or anyone else's) on this, and any
pointers regarding the errors in my code.
Thanks.
Alex Donnini
public View getView(int position, View convertView, ViewGroup
parent) {
ViewHolder holder;
holder = new ViewHolder();
try
{
if (convertView == null) {
convertView = mInflater.inflate
(R.layout.list_item_icon_text, null);
Button kill2 = (Button) findViewById
(R.id.kill2);
kill2.setOnClickListener(new
View.OnClickListener() {
public void onClick(View v) {
//Button click action processing
} });
holder.text = (TextView)
convertView.findViewById(R.id.text);
holder.icon = (ImageView)
convertView.findViewById(R.id.icon);
convertView.setTag(holder);
}
else {
holder = (ViewHolder) convertView.getTag();
Button kill2 = (Button) findViewById(R.id.kill2);
kill2.setOnClickListener(new View.OnClickListener
() {
public void onClick(View v) {
//Button click action processing
} });
}
holder.text.setText(activityList.get(position));
holder.icon.setImageBitmap((position & 1) == 1 ?
mIcon1 : mIcon2);
}
catch(Exception e)
{
e.printStackTrace();
}
return convertView;
}
