@seshu
You mean updating onListItemClick method in
TestListItemsView1Activity :
---------------------------------------------------------------------------------------------
protected void onListItemClick(ListView l, View v, int position,
long id) {
super.onListItemClick(l, v, position, id);
Toast.makeText(this, "Click-" + String.valueOf(position),
Toast.LENGTH_SHORT).show();
dataValues..remove(position);
}
---------------------------------------------------------------------------------------------
This does not work for me, I need to click remove button to remove
listrow.
My ListView contains [TextView and delete Button], I need to delete
list row, when I click on Delete button, When I click On Delete button
it will not enter into onListItemClick method under
TestListItemsView1Activity class , it will enter only when I select
TextView (Text).
Onlick method for delete button located in EfficientAdapter class.
