My app uses a gridview to display a list of values (imagine a
calendar). I have a button that forces the list of values to be
recalculated.
When the apps starts the grid view is correctly displayed and
individual cells can be selected and the correct position is displayed
(ie position 0 is at the top left and the last position is at the
bottom right).
When the button is clicked, the list is recalculated, invalidateview
is called to reload the view, all is well except when a cell is
selected the positions are reversed: ie. position 0 is now at the
bottom right and the last position is at the top left.
If the button is clicked again, the position reverts to the original.
Basically, for even clicks the position is correct and for odd number
the position is flipped.
This is the code I use is below, same as the code in the gridview demo
with the addition of the onsetclicklistener
Is this the behavior of a list? Should I keep track of hoe many times
the list is updated and recalculate the correct position index?
Thanks
public class MyAdapter extends BaseAdapter {
private Context context;
public MyAdapter(Context context) {
this.context = context;
}
public int getCount() {
return 48;
}
public Object getItem(int position) {
return null;
}
public long getItemId(int position) {
return 0;
}
public View getView(final int position, View
convertView, ViewGroup
parent) {
TextView tv;
if (convertView == null) {
tv = new TextView(context);
tv.setOnClickListener(new
View.OnClickListener() {
public void onClick(View view) {
Log.d("onClick","position "+position);
}
});
}
else {
tv = (TextView) convertView;
}
tv.setText(dateList[position]);
return tv;
}
}
