[android-developers] How to manage CheckBox or EditText item in a ListView ?

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 !

    }

    }

    }

}

   }
