I want to manage checkbox and edittext in a ListView.
I fill the list calling fill(), user (un)check and modify content of each
line, then I want to save modifications calling read(). Here is a sample
code.
What is the way to interact with the listview and get the modified content ?
Thank you for your help !
ArrayList<HashMap<String, String>> mylist = new ArrayList<HashMap<String,
String>>();
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
mContext = this;
managecontent();
}
void fill()
{
// fill the list
HashMap<String, String> map;
mylist.removeAll(mylist);
map = new HashMap<String, String>();
map.put("choice", "choice#1");
map.put("valeur", "123");
mylist.add(map);
map = new HashMap<String, String>();
map.put("choice", "choice#2");
map.put("valeur", "345");
mylist.add(map);
ListView list = (ListView) findViewById(R.id.choicelist);
SimpleAdapter listAdapter = new SimpleAdapter(mContext, mylist,
R.layout.line,
new String[] {"choice","valeur"},
new int[] {R.id.choice,R.id.value});
list.setAdapter(listAdapter);
}
void read()
{
// read the list / change content by program
View listItem;
CheckBox c;
EditText e;
String title;
ListView list = (ListView) findViewById(R.id.choicelist);
SimpleAdapter listAdapter = (SimpleAdapter) list.getAdapter();
if (listAdapter == null)
return;
for (int i = 0; i < listAdapter.getCount(); i++)
{
listItem = listAdapter.getView((int) i, null, list);
if (listItem!=null)
{
c=(CheckBox)listItem.findViewById(R.id.choice);
if (c!=null)
{
title=c.getText().toString(); // get the original label : choice#1
then choice#2
if (!c.isChecked())
{
c.setText("change !"); // no effect !
c.setChecked(true); // no effect !
}
e=(EditText)listItem.findViewById(R.id.value);
if (e!=null)
{
title=e.getText().toString();// always get the orignal content : 123
then 345 (not the data user set in the EditText item)
e.setText("X");// no effect !
}
}
}
}
}
